Question 1

it's not emptying the dustbin into the clean station, just docks and beeps then says check dustbin.

Accepted Answer

DIAGNOSIS The failure of the Samsung Bespoke Jet Bot Combo AI to empty its bin usually stems from a breach in the pneumatic seal between the robot's internal dustbin and the Clean Station's suction intake. When the robot docks and beeps with the "Check Dustbin" error, the system has detected that the expected airflow (measured in kPa) was not achieved during the vacuum cycle, triggering a safety timeout to prevent the motor from overheating. This is most commonly caused by a "bridge" of debris—such as a clump of pet hair or a piece of cardboard—lodged in the robot's exit port or the Clean Station's intake throat. Alternatively, if the Clean Station dustbag is saturated or improperly seated, the backpressure prevents the vacuum from pulling debris out of the robot, leading the sensors to believe the bin is still full or the path is obstructed. You can confirm this by listening for a high-pitched whistling sound during the docking process, which indicates a partial leak, or a muffled, strained motor sound, which indicates a total blockage. FIX Follow these precise steps to restore the auto-empty functionality: Inspect the Robot's Exit Port: Power off the robot. Remove the dustbin from the chassis. Look at the rear of the bin where the rubber flap is located. Use a flashlight to check for any stuck debris (like a pebble or hair clump) wedged in the seal. Manually push the rubber flap open and closed five times to ensure it snaps back instantly. Clear the Intake Throat: Inspect the base of the Clean Station where the robot docks. Look into the suction hole. If you see a clump of debris blocking the opening, use a pair of long-nose pliers or a vacuum hose to remove it. Ensure there is no plastic wrap or cardboard blocking the entry point. Reset the Dustbag Seal: Open the Clean Station lid. Remove the dustbag entirely. Check the cardboard collar of the bag; if it is bent or torn, the seal will fail. Reinsert the bag, ensuring the cardboard flange is pushed firmly and flush against the plastic housing. Slide the bag's plastic clip into the locked position. Clean the Bin Sensors: Use a dry microfiber cloth to wipe the contact points on the robot's dustbin and the corresponding sensors on the Clean Station to ensure the "Docked" signal is transmitting clearly. Test Cycle: Place the robot back on the dock and manually trigger an empty cycle via the SmartThings app to verify the fix. IF THAT DIDN'T WORK Check for Filter Saturation: If the HEPA filter inside the robot's dustbin is completely clogged with fine dust, air cannot flow through the bin, making it impossible for the Clean Station to suck out the debris. Remove the filter, tap it firmly against a hard surface, or replace it if it has turned dark grey. Inspect the Station Motor Vent: Check the rear and sides of the Clean Station for dust buildup on the exhaust vents. If the motor cannot breathe, it cannot create the necessary vacuum pressure to empty the bin. Use a handheld vacuum to clear the external grilles. Verify Bag Capacity: Even if the bag doesn't feel "heavy," micro-dust can clog the pores of the bag fabric, creating an air barrier. Replace the bag with a brand new genuine Samsung part to rule out fabric saturation. Perform a Hard Reset: Power the robot off using the physical switch on the side. Unplug the Clean Station from the wall for 60 seconds. Plug it back in and restart the robot to clear any cached sensor errors. HEADS UP Avoid Wet Debris: Never allow the robot to suck up liquids or damp materials. If wet debris enters the bin, it creates a "mud" that glues the dustbin flap shut, permanently damaging the auto-empty seal. Bag Replacement Timing: Do not wait for the "Replace Bag" notification. If you have high-shedding pets, replace the bag every 2 months regardless of the app status to maintain peak suction pressure. Avoid Third-Party Bags: Generic replacement bags often have thinner materials or slightly different collar dimensions, which can lead to air leaks and trigger the "Check Dustbin" error. Brush Roll Maintenance: Ensure the main brush roll is cleaned weekly. A clogged brush roll can cause the robot to push more debris into the bin than it was designed for, leading to more frequent "bridge" blockages in the exit port.

Question 2

the lidar cover on top keeps spinning but the robot isn't moving, then it errors out.

Accepted Answer

DIAGNOSIS The Samsung Bespoke Jet Bot Combo AI relies on a Laser Distance Sensor (LiDAR) that rotates at high speeds to map the room. When the LiDAR cover spins but the robot remains stationary before throwing an error (typically "Laser Sensor Error" or a red light blinking on the chassis), it indicates a "stalled motor" state. This happens when the internal spinning mechanism encounters physical resistance, causing the motor to draw too much current, which triggers a safety shutdown to prevent the motor from burning out. The root cause is almost always a foreign object—typically a strand of long hair, a piece of clear fishing line, or a thick dust bunny—that has bypassed the outer casing and wound itself around the spindle. Because the LiDAR is an optical system, even a tiny piece of debris can obstruct the laser's path or create enough friction to slow the RPMs below the required threshold. You can confirm this by listening closely: if you hear a rhythmic clicking or a high-pitched grinding sound before the error occurs, the spindle is physically obstructed. FIX To resolve the LiDAR stall, you must perform a manual clearance of the optical assembly. Follow these precise steps: Power down the unit completely by pressing the Power button on the top of the robot and ensuring it is not docked in the Clean Station. Locate the clear plastic LiDAR turret on the top of the device. Grip the outer ring of the cover firmly. Rotate the cover counter-clockwise approximately 15 degrees. You will feel a slight click as the locking tabs disengage. Lift the cover straight up and away from the chassis. Inspect the central silver spindle. Use a pair of fine-tipped tweezers or a needle to pluck out any hair or thread wrapped around the base of the rotating shaft. Do not pull forcefully, as you may bend the sensor arm. Using a can of compressed air, blow short bursts of air around the base of the spindle to clear out microscopic dust particles that may be causing friction. Manually flick the spindle with your finger to ensure it spins freely for several seconds without stopping abruptly. Reinstall the cover by placing it centered over the spindle and rotating it clockwise until you hear a distinct click, locking it back into place. Restart the robot and initiate a "SmartThings" map update to recalibrate the sensor. IF THAT DIDN'T WORK Hard Reset the Logic Board: If the sensor is clean but the error persists, the system may be stuck in a software loop. Hold the Power and Home buttons simultaneously for 10 seconds while the robot is off the dock. This clears the volatile memory and forces the LiDAR to re-initialize its startup sequence. Check for Drive Wheel Obstructions: The robot may be timing out because it thinks it is moving (due to the LiDAR spinning) but the wheels are physically jammed. Flip the robot over and inspect the two main drive wheels. Use a pair of scissors to cut any hair wrapped around the axle of the wheels, which can cause the robot to "slip" and trigger a navigation error. Clean the Optical Window: Use a dry, lint-free microfiber cloth to wipe the inside of the clear LiDAR cover. If there is a smudge or a fingerprint on the plastic, the laser may reflect back into the sensor, causing the robot to believe it is touching a wall when it is actually in open space, leading to a "stuck" state. Check for Infrared Interference: Ensure there are no high-intensity infrared heat lamps or direct, blinding sunlight hitting the LiDAR turret. Strong IR signals can "blind" the sensor, causing it to spin indefinitely while searching for a return signal, eventually timing out into an error state. HEADS UP Avoid Chemical Cleaners: Never use Windex, alcohol, or wet wipes on the LiDAR spindle or the interior of the cover. These chemicals can strip the anti-reflective coating off the laser lens, permanently degrading the mapping accuracy. Pet Hair Maintenance: If you have long-haired pets, check the LiDAR cover once every two weeks. Hair can migrate into the turret through the small gaps in the casing, leading to motor failure if left unaddressed. Avoid Manual Forcing: Never attempt to force the LiDAR spindle to rotate manually with a tool. The internal gears are precision-molded plastic and can snap easily, which requires a full sensor assembly replacement.

Question 3

the robot keeps getting stuck under my couch, it goes in but then just spins its wheels.

Accepted Answer

DIAGNOSIS The issue occurs because the Samsung Bespoke Jet Bot Combo AI possesses a chassis height that is nearly identical to the clearance of many modern couch frames. When the LiDAR sensor detects a gap, the robot attempts to enter; however, once inside, the top-mounted LiDAR turret or the chassis's upper edge makes physical contact with the underside of the furniture. This creates a "pinch point" where the robot is physically wedged, but not enough to trigger a hard collision sensor. Because the robot is stuck, the drive wheels lose traction on the floor, causing the "spinning wheels" behavior. The AI navigation system detects that it is not moving despite the motors running, which triggers a recovery loop. The robot will spin in place attempting to find an exit path, but because the friction from the couch frame is holding it in place, it cannot execute the reverse maneuver required to escape. You can confirm this by checking the SmartThings app for a "Stuck" or "Unable to move" notification, or by noticing the robot is centered exactly under the lowest hanging rail of your sofa. FIX To permanently prevent the robot from entering the "danger zone" under your couch, you must implement a digital perimeter using the SmartThings ecosystem. Follow these precise steps: Open the SmartThings App on your mobile device and select your Bespoke Jet Bot Combo. Navigate to the Map view. Ensure you have already completed a full "Home Mapping" run so the app has a precise layout of your living room. Tap on the No-Go Zone icon (usually located in the bottom menu or under the 'Map Settings' gear icon). Select Add Zone. Instead of a broad square, use the drag-and-drop handles to create a narrow rectangular strip exactly where the couch's under-clearance begins. Ensure the zone extends at least 2 inches beyond the actual edge of the couch to account for the robot's turning radius and sensor buffer. Tap Save or Apply. The map will now show a shaded red or grey area. The AI will now treat this area as a solid wall and will not attempt to enter the gap, regardless of what the LiDAR sees. IF THAT DIDN'T WORK Adjust Object Recognition Sensitivity: If the robot is still trying to "peek" into the zone and getting snagged, go to Settings > Robot Settings > Object Recognition. Change the sensitivity from 'Medium' to 'High'. This forces the AI to be more cautious around low-profile obstacles, making it more likely to avoid the couch entirely. Physical Furniture Risers: If you actually want the robot to clean under the couch, the clearance is likely less than 4.5 inches. Install heavy-duty rubber or plastic furniture risers (available in 1-inch or 2-inch increments) under the couch legs. This provides the necessary overhead clearance for the LiDAR turret to rotate without friction. Physical Barriers: If the software zones are glitching due to poor Wi-Fi signal in that specific corner, place a discreet physical object (like a decorative floor plant or a weighted doorstop) at the entry point of the couch's under-area. The Bespoke Jet's 3D sensors will detect the object and steer clear. Reset Mapping Data: If the robot is ignoring No-Go Zones, the internal map may be corrupted. Go to Map Settings > Delete Map and run a fresh mapping cycle. Ensure all doors are open and the floor is clear of small debris to ensure the most accurate spatial coordinates. HEADS UP Avoid Magnetic Strips: Do not waste money on third-party magnetic boundary strips. The Bespoke Jet Bot Combo relies on LiDAR and AI vision; it does not have a magnetic strip sensor and will drive right over them. Check the LiDAR Turret: Periodically wipe the top LiDAR sensor with a dry microfiber cloth. Dust buildup on the rotating sensor can cause "ghost" obstacles or a failure to recognize the boundaries of your No-Go Zones. Avoid "Dark" Under-Couch Areas: If your couch is extremely deep and dark, the AI vision sensors may struggle to distinguish the floor from the furniture frame, increasing the likelihood of the robot attempting to "explore" the void.

Question 4

the clean station makes a really loud high-pitched screeching noise when it empties the robot.

Accepted Answer

DIAGNOSIS The high-pitched screeching or whistling sound during the auto-empty cycle is almost always a result of "air cavitation" or a partial vacuum leak. This occurs when the Clean Station's powerful suction motor is attempting to pull debris through the robot's internal conduits, but the airflow is restricted by a dense clump of debris, a piece of cardboard, or a misplaced dustbag seal. When air is forced through a tiny gap at high velocity, it creates a sonic vibration—similar to a tea kettle—which manifests as that piercing screech. You can confirm this by checking the "Empty" indicator on the Bespoke Jet Bot Combo's display. If the robot reports the bin is still full despite the station running its cycle, there is a physical blockage. Additionally, inspect the dustbag; if the bag is not seated perfectly flush against the cardboard collar, air escapes around the edges rather than flowing through the bag, creating a high-frequency whistle. If the sound persists even with a brand-new bag and a clear path, the internal impeller bearing in the station's motor may have failed, though this is rare compared to simple blockages. FIX Follow these precise steps to clear the airflow path and seal the vacuum system: Power down the Clean Station completely by unplugging it from the wall outlet to prevent the motor from triggering while your fingers are near the intake. Open the front cover of the Clean Station and remove the dustbag. Carefully examine the cardboard mounting flange; if it is bent or torn, the seal will fail, causing the screeching sound. Using a high-lumen flashlight, look directly into the suction throat (the opening where the robot docks). Look for "bridge" blockages—large items like a clump of pet hair mixed with a piece of plastic or a thick coin—that may be partially blocking the aperture. Use a pair of long-nose pliers or a flexible vacuum retrieval tool to reach into the station's intake port and pull out any lodged debris. Do not use a screwdriver or metal rod, as you may puncture the internal plastic lining. Inspect the robot vacuum's own dustbin exit port. Ensure the rubber gasket on the robot's bin is clean and not pinched, as a poor seal here forces the station motor to work harder, increasing the pitch of the noise. Install a fresh, genuine Samsung Bespoke dustbag. Ensure the bag is pushed firmly back until it clicks into the holder and the plastic slide-lock is fully engaged. Plug the unit back in and trigger a manual empty cycle via the SmartThings app to verify the sound is gone. IF THAT DIDN'T WORK Check the Station Filter: Locate the motor filter at the top or rear of the Clean Station. If this filter is clogged with fine dust, the motor cannot "breathe," creating a high-pressure vacuum that screams. Remove the filter, tap it firmly against a hard surface to release dust, or replace it if it is grey/black. Inspect the Robot's Internal Conduit: Sometimes the blockage isn't in the station, but in the robot's internal "throat" leading to the bin. Remove the dustbin from the robot and use a flashlight to look up into the vacuum channel. Use a flexible pipe cleaner or a thin zip-tie to clear any compacted debris. Verify the Docking Alignment: If the robot is not docking perfectly flush against the station's intake, air leaks from the sides during the emptying process. Ensure there are no rugs or thick mats pushing the station slightly forward or tilting it, which prevents a vacuum-tight seal. Test with a Different Power Circuit: In rare cases, voltage drops on a shared circuit can cause the motor to run at an irregular frequency. Plug the Clean Station directly into a wall outlet rather than a surge protector or extension cord to ensure the motor receives full power. HEADS UP Avoid using generic third-party dustbags. Non-OEM bags often have slightly different dimensions or thinner materials that collapse under pressure, causing the air-leak screeching. If you have a high-pile carpet, move the Clean Station to a hard-floor surface. This ensures the robot docks at the exact millimetric angle required for a silent, airtight seal. Clean the robot's sensors and the station's charging contacts every 30 days with a dry microfiber cloth to ensure the robot docks precisely every time. If the screeching sounds more like "grinding" than "whistling," this indicates a mechanical bearing failure in the motor; stop use immediately and contact support for a motor assembly replacement.

Question 5

it won't connect to the smartthings app, gets stuck on 'connecting to your robot' forever.

Accepted Answer

DIAGNOSIS The "Connecting to your robot" hang is almost always caused by a handshake failure between the SmartThings app, your smartphone, and the robot's internal wireless module. The primary culprit is the dual-band nature of modern routers. The Samsung Bespoke Jet Bot Combo AI utilizes a 2.4GHz wireless chip for long-range penetration through walls; it cannot "see" or authenticate with 5GHz bands. When your phone is on 5GHz and the robot is attempting to bridge to the router, the SmartThings app often fails to pass the SSID and password credentials correctly, leaving the robot in a perpetual state of waiting for a confirmation packet that never arrives. Secondary causes include "Smart Network Selection" or "Band Steering" enabled on your router, which forces devices to a specific band based on signal strength. If the router tries to push the robot to 5GHz during the pairing process, the connection will time out. You can confirm this by checking your router's connected devices list; if the robot appears as "Connected" in the router but "Connecting" in the app, the issue is a firewall or IP conflict. If it doesn't appear in the router list at all, it is a frequency or credential mismatch. FIX Follow these exact steps to force a successful handshake: Isolate the 2.4GHz Band: Enter your router settings via your web browser. Temporarily disable the 5GHz band or, preferably, create a separate SSID for the 2.4GHz band (e.g., change "HomeWiFi" to "HomeWiFi_2G"). Save and restart the router. Phone Configuration: On your smartphone, go to Wi-Fi settings and "Forget" all previous networks. Connect specifically to the newly created 2.4GHz network. Turn off "Mobile Data" in your phone settings to prevent the app from switching to LTE/5G when the Wi-Fi signal momentarily drops during pairing. Hardware Reset: Power off the Bespoke Jet Bot Combo using the physical power switch on the unit. Wait 10 seconds, then power it back on. Place the robot on the Clean Station charging pins to ensure it has full power; a low battery can cause the Wi-Fi module to enter a power-saving mode that rejects new pairings. App Sequence: Open the SmartThings app. Delete any previous "ghost" versions of the robot from your device list. Tap the "+" icon, select "Add Device," and choose "Vacuum." When prompted, allow the app to access "Precise Location" and "Nearby Devices" permissions—without these, the app cannot scan for the robot's temporary setup broadcast. Final Pairing: Follow the on-screen prompts. When the app asks for the Wi-Fi password, double-check for typos. The robot's status light should blink rapidly during the "Connecting" phase and then turn solid once the handshake is complete. IF THAT DIDN'T WORK Disable Router Security Protocols: Some Bespoke models struggle with WPA3 security. Log into your router and change the security mode to WPA2-PSK (AES). Once the robot is connected, you can try switching back to WPA3, though WPA2 is the most stable for Samsung AI appliances. Clear SmartThings Cache: On Android, go to Settings > Apps > SmartThings > Storage > Clear Cache and Clear Data. On iOS, offload the app and reinstall it. This removes corrupted temporary pairing tokens that may be blocking the new connection. Change DNS Settings: In your router's WAN settings, change the DNS server to Google's Public DNS (8.8.8.8 and 8.8.4.4). Samsung's cloud servers occasionally fail to authenticate the robot's MAC address if the ISP's default DNS is lagging. Test with a Mobile Hotspot: To determine if the router is the problem, set up a mobile hotspot on a second phone using a 2.4GHz setting. Try connecting the robot to this hotspot. If it connects instantly, your home router's firewall or "Airtime Fairness" setting is blocking the robot. HEADS UP Avoid Special Characters: Ensure your Wi-Fi password does not contain complex symbols (like @, #, or $) as some firmware versions of the Jet Bot Combo fail to parse these characters correctly during the initial setup. Signal Dead Zones: The Clean Station acts as a shield. If your router is too far, the robot may connect but frequently drop off. Ensure the router is within 15 feet of the Clean Station for the initial pairing. Firmware Updates: Immediately after a successful connection, check for a firmware update in the SmartThings app. Samsung frequently releases patches specifically to improve Wi-Fi stability and connectivity. VPN Interference: Disable any active VPNs or Ad-Blockers (like NextDNS or AdGuard) on your phone during the setup process, as these intercept the local network discovery packets required for the "Connecting" phase.

Question 6

why is my bespoke jet leaving wet streaks instead of mopping? it just drags a dirty line.

Accepted Answer

DIAGNOSIS The "dirty line" or wet streaking effect on the Samsung Bespoke Jet Bot Combo AI is typically caused by a failure in the fluid distribution system or a saturation imbalance in the microfiber mop pads. When the pads are overly saturated or the water flow is set too high for the floor material, the robot ceases to "wipe" and instead begins to "plow" water and suspended particulates across the surface. This creates a concentrated trail of dirty water that settles into a streak as the robot moves forward. This issue is often compounded by "pad bunching," where the microfiber cloth shifts during the rotation or linear movement, causing one edge to drag more heavily than the rest. If you see a single, consistent line of residue, it is likely that the mop plate is not perfectly flush against the chassis, or the water pump is delivering a continuous stream rather than a controlled drip. You can confirm this by inspecting the mop pad after a cycle; if the center is dry but the edges are soaked, the pad is misaligned. If the entire pad is dripping, the flow rate is too high for your floor's absorption rate. FIX To resolve streaking and restore a clean wipe, follow these precise calibration and installation steps: Power down the unit and remove the mop plate assembly from the base of the robot. Detach the microfiber mop pads and rinse them under warm water. If they have been used for more than 10 cycles, replace them with new genuine Samsung pads, as worn fibers lose the capillary action required to lift dirt. Wring the pads out by hand until they are damp but not dripping. A common mistake is attaching bone-dry pads, which causes the robot to over-pump water at the start of the cycle to achieve saturation, leading to initial streaks. Align the pads precisely on the Velcro strips of the mop plate. Ensure the edges of the fabric are flush with the plastic rim of the plate; any overhang will cause the "dragging" effect. Slide the mop plate back into the robot chassis until you hear a distinct mechanical click. Gently tug the plate to ensure it is locked and not floating. Open the SmartThings App on your mobile device. Navigate to Robot Settings > Cleaning Settings > Mop Water Level. Change the setting from 'High' or 'Medium' to 'Low'. For polished hardwood or laminate, 'Low' is the only setting that prevents residue lines. Clear the floor of all loose debris using a "Vacuum Only" cycle before initiating the "Mop" or "Combo" mode. IF THAT DIDN'T WORK Check the water tank's rubber gasket and the intake valve. Remove the water tank and inspect the small rubber O-ring at the connection point. If there is a hair or piece of lint trapped here, it can cause an irregular pressure vacuum, leading to "glugging" where the robot releases a large burst of water instead of a steady stream. Clean the seal with a damp cloth and re-seat the tank firmly. Perform a "Hard Reset" of the water pump. Remove the water tank, turn the robot off and on again, and then re-insert the tank. This forces the AI to recalibrate the pump pressure for the current floor type. Inspect the mop plate for warping. If the plastic plate has been bent or scratched deeply, it will not maintain a consistent distance from the floor, causing the pad to dig in at one specific point. If the plate is warped, replace the mop plate assembly (Part No. check your specific regional model). Check for "Floor Residue Build-up." If you previously used a non-compatible floor cleaner or a wax-based product, the Bespoke Jet Bot may be reacting with the chemical residue. Mop the floor manually with a mixture of white vinegar and water to strip the residue before running the robot again. HEADS UP Never add detergent, bleach, or third-party cleaning solutions directly into the water tank. These chemicals can clog the microscopic nozzles of the distribution system, leading to permanent streaking or pump failure. Wash your mop pads in a washing machine without fabric softener. Softeners coat the fibers in a waxy layer, which prevents the pad from absorbing water and causes the robot to leave "slippery" streaks. Always empty and dry the water tank after a long period of non-use to prevent biofilm or algae growth, which can block the internal filtration system. Run the "Self-Cleaning" cycle on the station frequently to ensure the mop pads are being scrubbed effectively; a dirty pad will only move grime from one area of the room to another.

Question 7

the robot keeps saying 'please empty the dustbin' but i just did, it's not full at all.

Accepted Answer

DIAGNOSIS The "Please empty the dustbin" error on the Samsung Bespoke Jet Bot Combo AI is typically triggered by a false positive from the infrared (IR) proximity sensors. These sensors operate by emitting a beam of light that reflects off the debris inside the bin; when the light is interrupted or reflected back too quickly, the robot assumes the bin is at capacity. Because this model handles both vacuuming and mopping, humidity from the mop system can sometimes cause fine dust to "clump" or create a filmy residue on the sensor lens, tricking the AI into thinking the bin is full even when it is physically empty. Another common cause is a misalignment between the dustbin assembly and the internal chassis. If the bin is not seated with a perfect seal, the sensor may detect a gap or a reflection from the internal housing rather than the bin's interior. You can confirm this is a sensor issue if the robot triggers the alert immediately upon starting a cycle or immediately after you have manually emptied the bin and reinserted it without the robot having collected any new debris. FIX To resolve the sensor obstruction and reset the bin detection system, follow these precise steps: Power down the robot completely using the physical power switch located on the side or bottom of the unit to prevent accidental activation during cleaning. Remove the dustbin assembly by pressing the release trigger and pulling it straight out of the chassis. Locate the IR sensor window. Inside the robot's main cavity (where the bin slides in), there is a small, recessed clear plastic window. Use a dry, lint-free microfiber cloth or a cotton swab dipped in 70% isopropyl alcohol to gently wipe this window. Ensure there are no streaks or "ghosting" films left behind. Examine the dustbin itself. On the rear wall of the bin, there is a corresponding transparent area. Clean this surface thoroughly. If you see any gray buildup in the corners of the bin's interior, use a vacuum hose or compressed air to clear the edges, as dust trapped in the seams can interfere with the sensor's line of sight. Inspect the bin's rubber gaskets for any debris or hair that might be preventing the bin from clicking fully into place. Slide the bin back into the robot. You must hear a distinct, audible "click" to ensure the electronic contacts and the sensor alignment are locked. Restart the robot and run a "Test" cycle for two minutes to see if the alert persists. IF THAT DIDN'T WORK Perform a Hard Soft-Reset: Occasionally, the AI logic hangs on a cached error state. Turn the unit off, remove the dustbin and the mop pads, wait 60 seconds, and then reinsert everything. This forces the system to re-poll all sensors from a zero-state. Clean the Clean Station Dock: If you use the All-in-One Clean Station, the blockage might actually be in the dock's suction channel rather than the robot. Check the disposable dust bag in the station; if it is over-compressed or saturated, the station cannot pull debris out of the robot effectively, leading the robot to believe the bin is still full after a docking cycle. Inspect the Main Brush Roll: A massive clog of hair or a stuck object (like a coin or pebble) at the entrance of the dustbin channel can create a "dam." This debris reflects the IR sensor's light even if the rest of the bin is empty. Remove the brush roll and clear the intake throat using a long brush or tweezers. Update Firmware via SmartThings: Check the Samsung SmartThings app for a firmware update. Samsung has released several AI optimization patches for the Bespoke Jet Bot series that adjust the sensitivity thresholds of the bin sensors to reduce false positives. HEADS UP Avoid using wet wipes or soap on the sensor windows; residues from cleaning agents can create a haze that mimics the appearance of dust to the IR sensor. If you are vacuuming high-pile carpets, the "bin full" error may trigger more often due to the volume of fibers; consider increasing the frequency of manual bin checks. Always ensure the dustbin is pushed in until it clicks; a gap of even 2-3 millimeters can cause the sensor to misread the distance and trigger a false alert. Periodically clean the contact pins on the bottom of the robot and the dock to ensure the "empty" command is being communicated correctly between the two units.

Question 8

my bespoke jet bot combo is showing 'error 26' and just sits there beeping, what is that?

Accepted Answer

DIAGNOSIS Error 26 on the Samsung Bespoke Jet Bot Combo AI is a critical "Main Brush Obstruction" alert. This occurs when the robot's onboard current sensors detect that the motor driving the main roller brush is drawing excessive amperage, indicating that the brush cannot rotate at its required RPM. This is almost always caused by physical resistance—typically long hair, carpet fibers, or a foreign object like a piece of plastic or a thick string—winding tightly around the brush axle or the drive gear. When the brush is jammed, the system triggers a safety shutdown to prevent the motor from overheating or burning out. You can confirm this by attempting to manually rotate the brush with your finger while the unit is off; if it feels stiff or refuses to budge, the obstruction is internal. In some cases, the error is triggered not by the brush itself, but by a debris buildup in the brush housing that prevents the roller from sitting flush, causing it to rub against the plastic chassis. FIX To resolve Error 26, you must perform a deep clean of the brush assembly to remove all resistive materials. Follow these exact steps: Power down the unit completely by pressing the power button on the top of the chassis until the lights go off. Carefully flip the robot over onto a soft surface to avoid scratching the AI sensors or the mop pads. Locate the two plastic release latches on the main brush cover. Press these firmly inward and lift the cover plate upward to expose the main roller. Grasp the brush roller and pull it straight out of the housing. Note that if the brush is heavily jammed, you may need to wiggle it slightly to break the vacuum seal. Inspect both ends of the roller. Remove the end caps (if applicable to your specific regional sub-model) to access the axle. Use a pair of sharp scissors or a seam ripper to cut through hair and string wound around the bristles. Do not pull the hair forcefully, as this can warp the bristles or damage the plastic axle. Use a microfiber cloth to wipe the interior of the brush housing, specifically the gear teeth on the left side, to ensure no debris is interfering with the drive mechanism. Reinsert the brush, ensuring the alignment notches click firmly into place. Press the cover plate back down until you hear a distinct click on both sides. Flip the robot back over and initiate a "Test Run" via the SmartThings app to verify the error has cleared. IF THAT DIDN'T WORK Check the Side Spinners: While Error 26 specifically targets the main brush, a severely jammed side brush can occasionally cause a system-wide motor error. Remove the side brush by unscrewing the single Phillips head screw, clear any hair from the gear peg, and reinstall. Inspect the Drive Belt: If the brush is clean but the error persists, the internal drive belt may have slipped or snapped. Gently try to rotate the drive gear in the housing with a small screwdriver; if it spins freely without any resistance from the motor, the belt has failed and the brush assembly requires professional replacement. Hard Reset the AI Logic: Occasionally, the error persists in the cache. Hold the power button and the "Home" button simultaneously for 10 seconds to force a hard reboot of the onboard controller. Clean the Wheel Modules: Check the main drive wheels for jammed pebbles or debris. If the wheels cannot move the robot forward while the brush is spinning, the system may misinterpret the lack of movement as a brush jam. HEADS UP Avoid Wet Cleaning the Brush: Never rinse the main roller brush under a tap. Water can seep into the axle bearings, causing rust and permanent motor failure, which will trigger a permanent Error 26. Routine Maintenance: To prevent this error, clear the brush every two weeks if you have pets or long-haired residents. The AI sensors cannot detect hair buildup until the motor is already struggling. Manual Restart Required: After clearing a brush jam, the Bespoke Jet Bot will not automatically resume its path. You must manually restart the cleaning cycle via the SmartThings app or the physical button. Avoid Thick Rugs: If you encounter Error 26 frequently on a specific rug, the pile may be too high for the AI's torque limit. Use the "No-Go Zone" feature in the app to avoid these areas.
