COMMON CAUSES · RANKED

Debris in the lift mechanism MOST COMMON

Hair and grit collect in the moving parts behind the mop plate and stop it lifting or dropping.

Mop bracket not clicked in

A bracket seated at an angle binds the module the moment it tries to move.

Worn VibraRise module RARE

If a clean, correctly fitted module still jams, the actuator inside is failing — a support case.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Remove the mop cloth and bracket

Slide the mop bracket off the underside of the robot.

Clear the mechanism

Pull hair and debris out of the lift area and wipe the contact surfaces.

Reseat until it clicks

Refit the bracket flat and square — it should click in on both sides.

Run a short mopping test

Start a mop run and listen for the module's vibration. A repeat jam with a clean module means contacting support.
