Clear cords and floor clutter, then clean the obstacle and cliff sensors.
The Q Revo manual tells owners to keep appliance cords out of the cleaning area and to clean its obstacle-avoidance, wall, carpet and cliff sensors with a soft dry cloth. If it always gets stuck in one place, inspect that rug edge, narrow gap or wheel path before assuming the navigation system has failed.

Find what is trapping the Q Revo
Is there a cable, rug fringe, small object or very tight furniture gap where it gets stuck?
Check the exact location rather than the whole room.
How to stop repeated stuck events
Clear loose cords and small objects
Remove cables and loose items from the cleaning path. Roborock's Q Revo safety guidance specifically says appliance cords should be kept out of the area being cleaned.
Fix repeatable rug and furniture traps
Flatten curled rug edges, secure long fringe and open gaps that are just wide enough for the robot to enter but not turn around in.
Clean all navigation sensors
Wipe the Reactive Tech obstacle-avoidance sensor, wall sensor, carpet sensor and four cliff sensors with a soft dry cloth. Roborock lists these as routine sensor maintenance.
Inspect both main wheels
Remove trapped hair or fibers and check that each wheel moves and springs back normally. Do the same around the front omnidirectional wheel.
Use a no-go zone for an unavoidable trouble spot
If one carpet or transition remains problematic after physical cleanup, mark that area as a no-go zone in the app. The Q Revo manual explicitly supports carpet no-go zones.
Retest the same room
Start a normal clean from the dock and observe the previous trouble spot. If the robot now passes it repeatedly, the cause was environmental or maintenance-related rather than an internal navigation fault.
When to stop DIY
If the floor is clear, sensors are clean and the wheels move freely but the Q Revo repeatedly traps itself or behaves abnormally in open areas, avoid opening the LiDAR, drive-wheel assemblies or internal sensors. Use Roborock support or qualified service.
Use these guides when the symptom is more specific
Cannot Find Dock
Use this if the robot navigates the room but cannot reliably locate or return to the charging dock.
Side Brush Not Spinning
Use this if the robot moves normally but an edge brush is tangled or stopped.
