Dry litter can be flicked sideways by the side brush before the main intake reaches it. Slow the problem down: identify the litter type and contain the tracking area.

Start with these checks

  1. Remove wet or soiled litter manually before starting the robot.
  2. Try a second pass through the dry tracking zone with fewer nearby obstacles.
  3. Inspect the main brush and bin airflow if granules pass underneath without being collected.

What this looks like at home

Put a washable litter mat outside the tray and compare how much escapes beyond it; prevention can matter more than maximum suction.

Follow the debris path

Check What matters
Floor opening Look for lodged debris or a displaced brush cover.
Bin and seals Check closure and seating after emptying.
Filter Follow its own cleaning and drying instructions.

A mistake to avoid

A robot vacuum is not suitable for collecting cat waste or damp clumps.

Buy a part only after identifying the cause

Check the exact model and part reference before buying. If cleaning resolves the problem, a replacement may be unnecessary.

What the result tells you

Compare the area after one pass and after a second controlled pass. If most litter is simply pushed beyond the route, containment and path planning deserve attention before assuming the motor lacks power.
