Very useful!
I like my scrubber a lot! Great for faster coverage of larger spaces. Could use a bit more power but charges well & stay charged well. The flat scrubber sponge is the only one I have trouble keeping on it pops off a lot. The last one I had before this was bought second-hand years ago and I found it after getting this one and it still works and the batteries do interchange but the parts don't that's okay I still have two to work with.
