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 aimlessly, stops in the middle of a room, or drives near the dock but cannot align with the charging contacts. Roborock vacuums use a combination of LiDAR mapping and infrared dock signals to navigate home. The dock emits an IR beam that guides the robot for the final approach and alignment. Models with auto-empty or auto-mop docks (S7 MaxV Ultra, S8 Pro Ultra, S8 MaxV Ultra, Q Revo) have additional alignment requirements because the robot must connect to the dock dust port and water system precisely. Dock return failures trace to IR signal blockage, dirty charging contacts, dock position issues, or map corruption.

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 Roborock can see Wi-Fi but fails during setup handoff in the app, usually at 20-99% or right after password submission. The root causes are usually not just signal strength: 2.4GHz/5GHz steering, WPA3-only security, blocked local-network discovery, wrong app region, or stale robot pairing state. This guide walks a strict order that fixes the most common setup loops without factory-resetting maps.

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 robot vacuum displays a LiDAR sensor error, spins in circles, or bumps into furniture randomly instead of navigating in straight lines. The LiDAR turret on top of the robot spins at approximately 300 RPM to create a 360-degree map of the room. When the turret is blocked, dirty, or mechanically stuck, the robot loses its ability to navigate and falls back to bump-and-go behavior. This affects all Roborock models with LiDAR navigation including the S5, S5 Max, S6, S6 Pure, S6 MaxV, S7, S7 MaxV, S7 Max Ultra, S8, S8 Pro Ultra, S8 MaxV Ultra, Q5, Q7, Q7 Max, and Q Revo. The error message varies by model — common messages include "Laser distance sensor error", "LiDAR sensor blocked", "Please check if the LiDAR sensor is stuck", and error code 1.

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 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 visible streaks, water marks, or dirty lines on hard floors instead of cleaning them. This is the most common mopping complaint across all Roborock models with mop functionality: S7, S7 MaxV, S7 Max Ultra, S8, S8 Pro Ultra, S8 MaxV Ultra, Q Revo, and Q Revo Pro. The Roborock mop system uses a vibrating or rotating mop pad that scrubs the floor while a water tank dispenses solution. Streaks happen when the pad is dirty, the water flow is wrong, or the mop pad is not making proper contact with the floor. Models with auto-mop washing docks (S7 MaxV Ultra, S8 Pro Ultra, Q Revo) can develop streaks when the dock itself is not washing the pad effectively between rooms.

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 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.

Why Won't My Roborock Mop Scrub or Make Contact with the Floor?

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

Your Roborock mop module is attached but the mop pad is not scrubbing or making proper contact with the floor. The robot moves across the room but the mop either hovers above the floor, barely touches the surface, or does not vibrate or rotate. For streaking issues where the mop does touch the floor but leaves marks, see our Roborock mop streaks guide. This guide covers the mechanical and software reasons the mop module fails to engage: mop lift not disengaging on hard floors, vibration motor failure, rotating pad motor issues, and mop plate not lowering correctly.

Why Does My Roborock Map Keep Getting Deleted After Firmware Updates?

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

Every time your Roborock gets a firmware update your saved map disappears. You have to let the robot remap your entire house again then recreate all your room divisions, no-go zones, and furniture labels. This keeps happening with every update. Losing the map means losing hours of customization work.

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 is not spinning. The robot moves across the floor and suction may work, but the rubber or bristle roller brush does not rotate. This dramatically reduces cleaning performance because the main brush agitates carpet fibers and feeds debris into the suction path. Roborock models use different brush types: the S7 and S8 series use a full rubber brush (easier to maintain, no hair tangles), while the S5, S6, and Q5 use a bristle-and-rubber combination brush that tangles more easily. The brush is driven by a dedicated motor through a side coupling — the most common cause of brush failure is hair wrapping around the brush ends and bearings until the motor cannot overcome the resistance.

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.

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.
