Different dust extractor

Removing pet hair out of a bristle brush is a pain for a lot of users
Roomba 890 uses a new brush bar concept (called tangle-free debris extractor). It is a soft brushless roller bar to pick up debris and hair. This tangle-free brush bar is expected to be less tangle when dealing with hair. However, if you have a lot of pet hair and long hair at home, it is also tangled too (using scissors to remove the wrapping hair from this roller bar is easier compared with Roomba 690)
