Question 1

the side brush doesn't spin at all anymore, just hangs there during cleaning

Accepted Answer

DIAGNOSIS The side brush motor is obstructed or has failed. Hair and string commonly wrap around the brush's central post, seizing the mechanism. FIX Remove the side brush by pulling it straight off its post. Inspect the post and the brush's hub for wound debris. Clean thoroughly. Manually spin the brush on the post to ensure free movement. Reinstall. IF THAT DIDN'T WORK The motor gearbox under the side brush cover may be jammed. Remove the two screws securing the side brush cover and inspect for a debris jam in the gears. HEADS UP Check and clean the side brush post weekly. A seized motor will not be covered under warranty.

Question 2

it keeps missing big patches of floor, just goes around them like they're not there

Accepted Answer

DIAGNOSIS The robot's LiDAR navigation sensor, located on top, is dirty or obstructed. This prevents accurate room mapping and coverage. FIX Power off the robot. Locate the rotating laser turret under the clear dome on top. Use a dry microfiber cloth to gently wipe the entire clear dome and the spinning lens window. Ensure no objects like tall vases are placed on the robot. IF THAT DIDN'T WORK The room may be too dark. The LiDAR sensor requires ambient light. Turn on lights or open shades during cleaning cycles. HEADS UP Never place items on top of the robot. Never spray cleaners directly onto the LiDAR dome.

Question 3

shark app says my detect pro is offline even though the wifi router is right there

Accepted Answer

DIAGNOSIS The robot cannot maintain a connection to the 2.4 GHz Wi-Fi network. Dual-band networks or certain router security settings often cause this. FIX First, ensure your phone is connected to the 2.4 GHz band, not 5 GHz. In the router settings, temporarily disable WPA3 security or any 'Smart Connect' band steering. Set up a separate 2.4 GHz network with WPA2 security for the robot. Re-run the app setup. IF THAT DIDN'T WORK The robot's Wi-Fi module may need a reset. Hold the DOCK and MAX buttons on the robot for 10 seconds until it beeps. This resets network settings without deleting maps. HEADS UP The Shark Detect Pro does not support 5 GHz Wi-Fi. It must connect to a 2.4 GHz network.

Question 4

my robot's brushroll keeps stopping and it says 'clean brushroll' even though it's totally clear

Accepted Answer

DIAGNOSIS The brushroll end caps or the motor gearbox are jammed with fine hair and debris, not the main brushroll fibers. FIX Remove the brushroll. Use a small tool or scissors to cut and remove any hair wound tightly around the plastic end caps, especially in the deep grooves. Also, inspect the silver bearing on one end and the gear teeth on the other for obstructions. IF THAT DIDN'T WORK The brushroll motor or its sensor may be faulty. Manually spin the brushroll with your hand. It should turn freely with minimal resistance. HEADS UP Perform this cleaning every 2-3 weeks with pet hair or long human hair. Failure to clean end caps will burn out the motor.

Question 5

the auto-empty base makes a super loud grinding sound for a second when it runs, then stops

Accepted Answer

DIAGNOSIS A large or rigid piece of debris is caught in the base station's impeller fan. Common culprits are cat litter granules, cereal, or pebbles. FIX Unplug the base. Remove the clear debris canister. Shine a flashlight into the metal impeller chamber at the bottom of the base. Use long-nose pliers or tweezers to carefully remove any foreign object lodged between the impeller blades. IF THAT DIDN'T WORK The impeller itself may be cracked or damaged. Inspect the plastic blades for breaks. This requires part replacement. HEADS UP Regularly check the robot's bin for large debris before docking to prevent this. The impeller is not user-serviceable; contact support if damaged.

Question 6

shark detect pro is stuck in one room and won't go back to its base, just wanders the perimeter

Accepted Answer

DIAGNOSIS The robot has lost its map and cannot locate the base station. This occurs after a factory reset, moving the base, or a significant change in room landmarks. FIX Manually return the robot to the base. In the SharkClean app, go to Map & Positioning. Select 'Update My Smart Map'. Run a full cleaning cycle without interruptions to allow the robot to rebuild its map. Keep the base station in its permanent location. IF THAT DIDN'T WORK Ensure the base is plugged in directly to a wall outlet, not a power strip. Clear a direct path of at least 3 feet in front and 1.5 feet on each side of the base. HEADS UP Do not move the base station after a map is saved. Moving it will cause navigation failures.

Question 7

robot keeps saying 'clean cliff sensors' but i already wiped them, it won't start cleaning

Accepted Answer

DIAGNOSIS The robot's infrared cliff sensors are dirty or obstructed. Wiping the clear plastic covers is not sufficient if the sensor lens underneath is obscured. FIX Power off and flip the robot. Locate the four clear plastic sensor windows on the underside. Use a dry cotton swab to gently clean the actual sensor lens inside each window. Ensure no stray brush bristles are dangling over the sensors. Power on. IF THAT DIDN'T WORK The error can be triggered by a very dark or solid black floor surface that absorbs the infrared light. Place a light-colored mat or run the robot in a different room to test. HEADS UP Do not use liquids or cleaners on the sensor windows. Moisture can damage the internal electronics.

Question 8

my shark detect pro won't empty its bin into the base, it just makes a loud noise and gives an error 7

Accepted Answer

DIAGNOSIS The bin is not docking properly with the auto-empty port. Error 7 indicates a bin removal or docking fault. The most common cause is a clog in the vacuum's dust bin intake or the base's hose. FIX First, remove the robot's dust bin. Inspect the rubber flap and the rectangular intake port on the back of the bin for debris. Clear any blockage. Second, detach the clear debris canister from the base station. Check the flexible hose inside the base for a clog. Remove any obstruction. Reassemble and run a manual empty cycle. IF THAT DIDN'T WORK The bin may not be fully seated. Ensure the bin is clicked completely into the robot. Also, clean the bin's electrical contacts and the corresponding pins inside the robot with a dry cloth. HEADS UP Do not use compressed air to clear the base hose, as it can force debris deeper. Manually remove any visible blockage.
