Possible Causes

Clogged main filter, Dust bin overfilled, Debris blocking suction channel, Worn or damaged main brushes, Air leak around bin seal

How to Fix / Troubleshooting

Safety first: Turn off the robot and remove it from the Home Base before cleaning.

Steps to improve cleaning:

  • Empty the bin: Remove and fully empty the dust bin. Tap it gently to dislodge compacted dust.
  • Clean or replace filter: Remove the filter from the bin. Tap it against a trash can to remove dust (outdoors if possible). Replace the filter if it is more than a few months old or visibly damaged.
  • Check suction path: Inspect the bin’s suction inlet and the robot’s suction channel for clumps of hair or debris and remove them.
  • Inspect main brushes: Remove and clean the main brushes and end caps. Replace brushes if they are worn smooth, cracked, or permanently deformed.
  • Check bin seal: Inspect the rubber gasket around the bin opening for tears or deformation; ensure the bin seats tightly.

When to replace parts: If suction remains weak after cleaning, replace the filter and main brush set. Persistent low suction may indicate a failing vacuum motor.
