Replacement brushes are too short, rattle, and make a horribly loud noise. The result is a significant loud “rumbling” noise while operating. They are so noisy that it drives us round the bend.

Not compatible as described. Keeps popping up because the plastic attachment is too long. Had to tape the lid shut. After resetting, it works a minute or two and again stops with an error code.

Clearly not well designed, or cheaply manufactured. I’m not sure how this product rated so high but not worth the money!
