this was meant for rumba machines I have a friend dog, a labrador retriever who thinks there's nothing better in the world than me. Hearing does a good job of lifting hair. I didn't have my original filter so I decided to try these to see how they would work. The filter seemed to pick up a lot of fine dirt, which also came from just living on the floor and carpet, possibly including dog hair. The brush is easy to clean. It's been a good experience so far.
