A mid-clean stop needs its error message preserved. A tangled wheel, full bin or exhausted battery calls for a different response from an app disconnection.

Start with these checks

  1. Photograph the error and battery level before clearing anything.
  2. With the robot off, check accessible brushes, wheels and the dustbin.
  3. Run the same room again with cables lifted and observe the stopping point.

What this looks like at home

Stopping at exactly the same doorway suggests a physical obstacle; stopping at different locations near empty charge suggests workload or charging.

Test the machine and the obstacle separately

Check What matters
One location only Examine the shape, surface and escape route.
Every location Check accessible wheels, bumper and brush assembly.
After maintenance Recheck the fitted parts before changing the map.

A mistake to avoid

Do not factory-reset first: it can erase useful evidence and your room map.

Buy a part only after identifying the cause

Check the exact model and part reference before buying. If cleaning resolves the problem, a replacement may be unnecessary.

What the result tells you

If the same patch repeatedly ends the job, photograph the floor and obstacle there. If the stopping point varies, record the battery level and error from each run; that makes a location fault easier to separate from a machine fault.
