Robot vacuum’s wheels spin but the unit barely moves forward, especially on carpets.

Safety first: Turn OFF and flip the robot over before inspecting wheels and brush.

Steps to try:

• 1. Clean wheel surfaces: Wipe the rubber treads with a damp cloth to remove dust or slippery residues, then dry thoroughly.
• 2. Inspect tread wear: If the rubber is smooth or cracked, replace the drive wheel assemblies.
• 3. Reduce brush drag: Clean the main brush and bearings to reduce resistance.
• 4. Test on hard floor: If movement is acceptable on hard floors but not carpets, consider reducing carpet thickness in cleaning areas or replacing worn wheels.
