Why Won't My Roborock S8 Pro Ultra Dock Empty the Dustbin?

Device: Roborock S8 Pro Ultra (Roborock S8 Pro Ultra, S8+, S8 MaxV Ultra, Q Revo)

Your Roborock returns to the dock after cleaning but the auto-empty feature does not activate leaving the dustbin full. The dock should vacuum the dustbin contents into the dock bag automatically but no suction sound occurs and the dustbin remains full.

Why Won't My Roborock Return to the Dock?

Device: Roborock Robot Vacuum (S7, S8, S8 Pro Ultra, Q5, Q7 Max, Q Revo)

Your Roborock robot vacuum finishes cleaning but fails to return to its charging dock. The robot wanders near the dock area or drives past it repeatedly without successfully parking on the charging contacts. Eventually the battery dies and the robot stops in the middle of a room. Without successful docking the auto-empty and auto-mop-wash features on Ultra models never activate and the robot cannot recharge for the next scheduled cleaning.

Why Does My Roborock Mop Leave Streaks and Not Clean Properly

Device: Roborock Robot Vacuum (S8 Pro Ultra, S8 MaxV Ultra, S7 MaxV Ultra, Q Revo, S8)

Your Roborock mop leaves streaks on hard floors instead of cleaning them. The mop starts wet but dries out or drags dirty water creating visible streaks. Roborock has not solved this across multiple generations. The root cause is usually a warped mop plate inadequate water flow or dirty mop pads redistributing grime.

Why Does My Roborock Keep Saying Laser Sensor Error or LiDAR Blocked

Device: Roborock Robot Vacuum (Roborock S7, S7 MaxV, S8, S8 Pro Ultra, Q7 Max)

Your Roborock displays a Laser Distance Sensor Error or LiDAR Cover Blocked message and either spins in circles, stops mid-clean, or refuses to start. The LiDAR turret — the small spinning dome on top of the robot — powers the entire navigation system. When it cannot spin freely or its laser window is obstructed, the robot loses its ability to build or follow a map and throws this error. In the majority of cases the cause is dust or a thin film on the turret window, hair wrapped around the turret shaft, or direct sunlight shining into the room. A physical obstruction blocking the turret from rotating is less common but also possible.

Why Does My Roborock Show a LiDAR Error and Spin in Circles?

Device: Roborock Robot Vacuum (S7, S8, S8 Pro Ultra, Q5, Q7 Max, Q Revo)

Your Roborock displays a LiDAR sensor error and spins in circles or bumps into furniture randomly. The error typically reads Check that the LiDAR turret turns freely or Error 1. The LiDAR turret on top may be physically stuck or the internal laser sensor has failed. This renders the robot unable to map or navigate making it useless for autonomous cleaning.

Why Is My Roborock Not Connecting to WiFi During Setup?

Device: Roborock Robot Vacuum (Roborock S7, S7 MaxV, S8, Q5, Q7, Q Revo, S6, S5 Max)

Your new Roborock robot vacuum fails to connect to WiFi during initial setup. The app may time out, show connection failed, or get stuck on connecting to robot. The robot may announce WiFi connection failed or the indicator light keeps blinking. This prevents app control, scheduling, and map features.

Why Is My Roborock Mop Pad Soaking the Floor Instead of Lightly Dampening It?

Device: Roborock Robot Mop (Roborock S7, S7 MaxV, S8, S8 Pro Ultra, Q7 Max+, Roborock Mop)

Your Roborock robot mop is depositing too much water on the floor during a mopping run, leaving it visibly wet rather than lightly damp. Puddles or saturated sections appear behind the vacuum as it mops. Hardwood floors are at risk of water damage when the mop over-saturates. This is different from streaking caused by a dry or dirty mop pad. Over-saturation is caused by the water flow setting being too high for the floor type, a clogged or faulty water pump delivering intermittent bursts, or the mop module not being properly seated to regulate water flow.

Roborock Dock Station Leaking Water on Floor

Device: Roborock Auto-Empty Dock / Dock Ultra (S7 MaxV Ultra, S8 Pro Ultra, Q Revo)

Your Roborock docking station with auto-mop washing and filling capabilities is leaking water onto the floor. You may find puddles around the dock, the dirty water tank overflowing, or water dripping from the clean water tank area. This can damage your flooring and indicates a problem with the dock's water management.

Why Won't My Roborock Dock Wash the Mop Pad Properly?

Device: Roborock Dock Station (S8 Pro Ultra Dock, Q Revo Dock, S7 MaxV Ultra Dock)

Your Roborock auto-wash dock station is not properly cleaning the mop pad when the robot returns. The pad comes out of the wash cycle still dirty stained or smelling bad. The dock may run through washing motion but the pad is no cleaner. Dirty water may not drain properly or fresh water is not dispensed. This means the robot spreads dirty water across floors on subsequent passes instead of cleaning with a fresh pad.

Why Won't My Roborock S8 MaxV Ultra Lift the Mop When It Goes on Carpet

Device: Roborock S8 MaxV Ultra (S8 MaxV Ultra, S8 Pro Ultra, VibraRise)

Your Roborock S8 MaxV Ultra is not lifting its mop when it encounters carpet even though mop lifting is enabled. The robot drags the wet mop across your carpet, getting it wet and potentially causing damage. The VibraRise mop lift feature seems to be not working properly.

Why Won't My Roborock Mop Clean Properly or Leaves Streaks?

Device: Roborock Robot Vacuum (S7, S8 Pro Ultra, Q Revo, S7 MaxV Ultra)

Your Roborock mop leaves dirty streaks or water marks instead of actually cleaning the floor. The mop pad may drag across the floor without scrubbing or the water tank dispenses too little or too much water. This turns mopping into pushing dirty water around which defeats the purpose of a combo vacuum and mop unit.

Why Is My Roborock Main Brush Not Spinning?

Device: Roborock Robot Vacuum (Roborock S7, S7 MaxV, S8, Q5, Q7, S6, S5 Max, E4)

Your Roborock robot vacuum runs but the main brush underneath does not spin. You may notice poor cleaning performance, debris left behind, or the brush sitting motionless. The app may show a brush error or the robot announces main brush tangled. This dramatically reduces cleaning effectiveness.

Why Is My Roborock Q Revo Mop Pad Not Drying and Smells Bad

Device: Roborock Q Revo (Roborock Q Revo, Q Revo Pro, Q Revo MaxV, Q Revo Master)

Your Roborock Q Revo finishes cleaning and returns to the dock, but the mop pads remain wet and develop a musty or mildew smell. The auto-dry function either does not activate or runs but fails to fully dry the pads. Wet pads left in the dock overnight grow bacteria and create an unpleasant odor.

What Does Roborock Error 18 Mean and How Do I Fix Fan or Suction Faults

Device: Roborock Robot Vacuum (S5, S6, S7, S8, Q5, Q7, Q Revo)

Roborock Error 18 is typically tied to vacuum fan malfunction behavior where suction weakens or stops, and the robot exits cleaning runs early. Users often report sudden loud fan changes before failure. This can come from debris in the fan path, filter restrictions, or fan wear after extended heavy use.

Why Does My Roborock S8 MaxV Ultra Keep Running Into Obstacles?

Device: Roborock S8 MaxV Ultra (Roborock S8 MaxV Ultra)

Your Roborock S8 MaxV Ultra has advanced obstacle avoidance with cameras and AI but it keeps running into objects and pushing things around.
