Question 1

the auto-empty dock for my s7 is super loud and sounds like it's choking, but no dustbin is full.

Accepted Answer

DIAGNOSIS That choking sound is the dock's motor straining because the airflow path is blocked. It's not the main bin; it's a clog in the internal tubing or the robot's dust port. FIX 1) Unplug the dock. 2) Remove the dust bag and look inside the empty chamber. Use a flashlight to check the opening where the bag sits—you might see a clump of dust and debris. Carefully clear it with a long, thin tool (a straightened coat hanger works). 3) Now, check the robot's side. Clean the rubber seal around its dust port. 4) Most importantly, take out the robot's main dustbin and look at the small, rectangular hole on the back of it. Clear any compacted dust from that opening and the filter inside the bin. IF THAT DIDN'T WORK The clog could be deeper in the hose between the dock's opening and the bag chamber. Detach the hose from the dock (if your model allows) and blow through it or use a vacuum to pull debris out from the other end. HEADS UP Never use compressed air to blast a clog deeper into the dock—you could damage the internal motor. Always work from the bag chamber back towards the opening. And empty the robot's bin more frequently than the dock's bag; a overfull robot bin is the number one cause of these clogs.

Question 2

roborock s7 won't connect to my wifi during setup, it just times out every single time.

Accepted Answer

DIAGNOSIS This is almost always a 2.4GHz vs. 5GHz network issue. The S7 only connects to 2.4GHz networks, and many modern routers broadcast both under the same name, which confuses the robot. FIX 1) Go into your router's settings (usually via a web browser) and temporarily create a separate, uniquely named network that is 2.4GHz ONLY. 2) Disable any "band steering" or "smart connect" features that automatically switch devices between bands. 3) On your phone, forget your home wifi and connect to this new 2.4GHz-only network. 4) Now try the Roborock app setup process again. It should find the robot and connect smoothly. After setup, you can reconnect your phone to your main network; the robot will stay on the 2.4GHz one. IF THAT DIDN'T WORK The robot's wifi antenna might be struggling with distance or interference. Move the dock and your router closer together for the initial setup, avoiding thick walls or microwave ovens in between. HEADS UP Some mesh network systems can also cause problems. If you have one, try connecting the robot to the main router's signal, not a satellite node, for the initial pairing. The robot's wifi chip isn't the most powerful, so it needs a strong, simple signal to handshake.

Question 3

why does my roborock s7 keep missing big obvious spots? it goes around whole sections of the room.

Accepted Answer

DIAGNOSIS This is typically a sensor issue. The cliff sensors (usually four, on the underside) are getting "phantom" drops, making the robot think there's a staircase where there isn't one, so it avoids the area. FIX 1) Flip the robot over. 2> You'll see small, clear plastic windows near each wheel. These are the cliff sensors. Clean them thoroughly with a dry Q-tip or soft cloth. 3) Also, check the corresponding reflective surface right next to each sensor window and clean that too. 4) The problem is most common on very dark, shiny floors (black tile, dark hardwood) that don't reflect the sensor's light back properly. Try turning off the cliff sensors in the app's settings if you have no actual drop-offs, but do this with caution. IF THAT DIDN'T WORK Strong, direct sunlight flooding the floor can also blind the sensors. Try running it at a different time of day or closing the blinds to see if the behavior changes. HEADS UP Don't use glass cleaner or liquids directly on the sensor windows. Moisture can seep in and damage them. A dry microfiber cloth is all you need. If the problem only happens on specific rugs, the pattern or fringe might be tricking the sensors.

Question 4

my s7 is vacuuming fine but it won't map my house at all, the map is just a blank grey blob.

Accepted Answer

DIAGNOSIS The LiDAR sensor on top isn't getting a reading, usually because it's physically obstructed or its spinning mechanism is jammed. FIX First, check for obvious blockages. 1) Power the robot off. 2) Look at the clear plastic dome on top—the LiDAR tower. Wipe it clean with a dry microfiber cloth. 3) Now, gently try to rotate the silver disc underneath the dome with your finger. It should spin freely and smoothly. If it's stuck, carefully clear any hair or string wrapped around its base. 4> Power it back on. You should see the LiDAR spin up immediately and hear a faint whirring sound. IF THAT DIDN'T WORK The robot might be starting in a very dark room. The LiDAR uses lasers, but it still needs some ambient light for its other sensors to initialize. Try moving the dock to a brighter area or turning on some lights for the first few mapping runs. HEADS UP Never place objects on top of the robot or store it under a shelf that rests on the LiDAR dome. Even slight pressure can misalign the delicate mechanism inside, leading to permanent mapping failure.

Question 5

the vibrating mop on my s7 is making a really loud grinding noise, sounds like it's gonna break.

Accepted Answer

DIAGNOSIS That grinding is almost always a foreign object—like a small piece of gravel, glass, or hard debris—caught between the vibrating mopping plate and the robot's chassis. FIX 1) Remove the water tank and mop pad assembly. 2) Look at the silver mopping plate that vibrates. You'll need to detach it. Push the two plastic locking levers on the sides inward and lift the plate off. 3) Now inspect the cavity where the plate sits and the underside of the plate itself. Remove any debris. 4) Also, check the mop pad's velcro area on the plate for stuck-on bits. 5> Reattach the plate, ensuring it clicks securely into place on both sides before putting the cloth back on. IF THAT DIDN'T WORK The noise could be from the plate's motor or gears failing. Without debris, try running a mopping cycle with the plate detached (just set the robot on the floor). If it's still making a bad mechanical noise from inside the robot, the mopping module itself likely needs service. HEADS UP Always do a quick vacuum run before mopping, especially on hard floors. The mop plate sits very low and will suck up any small, hard objects that the main brush might have missed, causing this exact problem.

Question 6

roborock s7 keeps getting error 13, what does that mean and how do i stop it?

Accepted Answer

DIAGNOSIS Error 13 means "Main Brush stuck." It's not necessarily that your brush is tangled, but that the robot's motor is detecting too much resistance when it tries to spin. FIX 1) Flip the robot over. 2) Remove the main brush cover by pressing the two tabs. 3) Take out the main brush itself and clear any hair, string, or debris wrapped around the ends of the brush or inside the bearing housing. 4) Also, check the side brush—if it's mangled or caught on something, it can cause enough drag to trigger the error. Clear that too. 5) Reinstall everything, making sure the brush spins freely by hand before you click the cover back on. IF THAT DIDN'T WORK The issue might be the brush cover not being fully snapped into place, which misaligns the brush. Remove and firmly reseat it, listening for a solid click on both sides. A worn-out main brush with bent fins can also cause constant resistance and needs replacing. HEADS UP Run your fingers along the entire brush chamber with the brush removed. Sometimes a staple or small rock gets lodged in there, causing friction you can't see. That'll give you the error even with a brand new brush.

Question 7

just got an s7 and the mop pad isn't getting wet at all, it's just dragging a dry cloth around.

Accepted Answer

DIAGNOSIS The most common cause is air trapped in the internal water tank's tubing, blocking the flow. It happens often with a brand new unit or if you've let the tank run completely dry. FIX You need to prime the water pump. 1) Remove the water tank from the robot. 2) Fill it completely to the max line, seal it, and then turn it UPSIDE DOWN. 3) Gently squeeze the tank a few times. You should see water droplets come out of the mopping module's nozzle. 4) Keep it upside down, reattach it to the robot, and start a mopping-only cycle. The vibration should push the rest of the air out and water will start flowing. IF THAT DIDN'T WORK Check the mop pad itself. The grey, rubberized 'water guide' plate must be installed correctly between the cloth and the robot. If it's missing or upside down, water can't wick through to the cloth. HEADS UP Only use water in the tank. Cleaning solutions or vinegar can clog the tiny nozzles and valves in the mopping module, which is a much harder fix than clearing an airlock.

Question 8

my roborock s7 is stuck on 'charging' but the battery never goes above like 20%, it just sits there forever.

Accepted Answer

DIAGNOSIS This is usually a battery communication or calibration issue, not a charging hardware problem. The robot thinks it's charging, but it's not actually accepting a full charge from the dock. FIX First, let's try a hard reset to clear the communication glitch. 1) Pick the robot up off the dock. 2) Press and hold the power button on the side for about 15 seconds until you hear a shutdown sound and all lights go off. 3) Place it back on the dock, making sure the charging contacts on the robot and dock are clean and touching. Let it sit for a full, uninterrupted 4-6 hours. This often forces a proper calibration cycle. IF THAT DIDN'T WORK The battery itself might be failing and not holding capacity. You can check this by manually starting a cleaning run after it says it's charged. If it dies almost immediately, it points to a bad battery that needs replacement. HEADS UP Constantly running it from a low state of charge can permanently damage lithium batteries. If the hard reset doesn't fix it within a day, stop the cycle and look into a replacement battery to prevent further damage to the system.
