DIRECT ANSWER

Error 3 means a wheel is hanging in the air. The robot is beached on a threshold, a chair base or a stair edge and refuses to drive. Set it back on flat floor and restart.

COMMON CAUSES · RANKED

1

Robot beached on an obstacle MOST COMMON

Door thresholds, chair bases and floor lamps lift the chassis just enough for a main wheel to lose contact.

2

Robot half over a drop

One wheel over a stair edge or sunken floor leaves the suspension fully extended.

3

Robot picked up mid-clean

Carrying the robot while it runs triggers the same wheel-drop sensors.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Lift the robot clear

Pick it up off the threshold or obstacle it is stranded on.

Check both main wheels

Press each wheel in and let it spring back. Pull out any debris in the wheel wells.

Restart on flat floor

Place the robot on open, level ground and start the clean again. Block off the trouble spot in the app if it repeats.
