Review on Impressive iRobot Authentic Replacement Parts - 800 and 900 Series AeroForce High-Efficiency Filters (3-Pack) by Brett Kolpack

This time I bought the original. They took our rumba with the original filter. Didn't know we had to change parts so often and they were so expensive! We've had fakes (8 I think) and they lasted about a month, each of which worked on average. 3 times a day. Once on each floor of the house. My husband said to try the legal ones to see the difference. Instantly? 4 times more expensive. I got 3 for $20 when I could get 8 for $16. I noticed that the cheap ones have a fabric cover on the suction side, which severely limits the suction power. It's like sucking on a filter cigarette instead of an unfiltered cigarette. I think the ability to pick things up is better, but for a simple pick up like animal fur? Go the cheap way. An easy hit for your money.
