* I will use them but will never buy them again. The screen turns off quickly. Probably, the Chinese think that the additional screen somehow improves cleanliness, but they are wrong. I would rather buy the more expensive iRobot models as there are two companies involved, the UK and the US who are the manufacturers. I would rather support US jobs and get a better product. My other iRobot filters have lasted quite a long time - several months. They won't last long...I should have noticed they are the same type I've bought before and in a week I won't be able to reuse or clean them. I'll be more careful next time I buy. *ETA: I tried the new one again. Turns out the inside is plastic too...fine dust goes through the whole system and Roomba gets dirty, dust everywhere. I will NOT really use them again.
