Robot vacuum frequently reports 'stuck' or stops in open areas without visible obstacles.

Safety first: Turn OFF the robot before manipulating the bumper.

• Test bumper movement: Press the bumper in and release across its width. It should move smoothly and return fully.
• Clean bumper gap: Use compressed air or a thin brush to remove dust and debris from the gap between the bumper and body.
• Inspect springs: Look for broken or dislodged springs visible through the bumper gap.
• Power cycle and test: Turn the robot ON and run it in an open area to see if the false stuck messages continue.
• Service if needed: If the bumper still misbehaves, the internal switch assembly may need adjustment or replacement.
