Installation Tips

• Ensure the robot vacuum is powered off before performing any part replacements.
• When installing rollers, match the square and hexagonal end-caps with the corresponding icons on the cleaning head module.
• The corner-cleaning brush requires a small screwdriver for removal; ensure the screw is tightened firmly but do not over-torque.
• Snap filters firmly into the dust bin housing to ensure a vacuum-tight seal.
• Use the included cleaning tool regularly to clear the roller bearings, as hair accumulation can cause mechanical resistance and battery drain.
