Save time and money Buy genuine Neato parts. I bought this replacement set instead of spending $49 thinking it would work. Well now my botwak picks up NOTHING on startup. I literally don't even have to empty the trash can. I don't know if the brush is useless or if the filter doesn't let anything through (I thought it was a brush) but now I'm spending $49 on genuine parts and wasting $30. You get what you pay for.
