COMMON CAUSES · RANKED

Clogged filter forcing the motor MOST COMMON

A blocked filter makes the fan fight for every bit of air, and heat builds fast.

Debris on the impeller

Hair or fluff wound into the fan unbalances it and adds friction.

Vacuum motor failing RARE

A motor that overheats with a clear airway is on its way out.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Give it time to cool

Park the robot and deal with the airway before asking the motor to spin again.

Fit a fresh filter

Don't try to revive a dust-caked filter after an overheat — replace it.

Clean the fan and scroll

Inspect the vacuum entrance and exhaust and blow the assembly out with compressed air.

Escalate if it repeats

Overheating with a clean air path means the motor or cleaning head assembly needs replacement — contact support.
