Bought for my Roomba. I have 3 dogs and 3 cats so the filter needs to be cleaned every day. With roomba's branded filters, I was able to blow them out with compressed air and extend their life, but with this one. The weave/mesh/filter material is different, so you can't blow it like that. I have to replace it about once a month because eventually Yvonne's Roomba will NOT tell me the trash is empty until I give her a new one.
