Sudden loss of pickup is often about restricted airflow rather than a changed motor rating. Work along the short path from the floor opening to the bin and filter.

Start with these checks
- Empty the dustbin and check the intake for a compacted hair plug.
- Inspect and clean the filter exactly as its manual permits.
- Refit the brush, bin and cover, then compare the same small debris area.
What this looks like at home
A full-looking bin is not required for a blockage: a felted layer of fine dust on the filter can restrict airflow.
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
Never run the robot without its required filter to test whether suction improves.
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.
Browse Amazon UK results for robot vacuum compatible replacement filters. These are search results, not a verified recommendation for your particular machine.
What the result tells you
If cleaning the permitted filter and intake restores pickup, track how quickly they load again. A rapid recurrence may point to unusually fine dust or a damaged part rather than a need for maximum suction at every run.
