What should I do if the robot alerts: Error 42 Maintenance brush jammed?

The following applies to S7MaxV Ultra, S7Max Ultra and S8 Pro Ultra.

  1. If the brush stops at the left side, it may be jammed. Remove any items jamming it.
  2. If the brush stops at the right side, the filter may be blocked or is not installed in place. Clean and correct installation.

If the issue persists, please contact Customer Support for further assistance.
