Purplepixie's response is exactly what I would put. I hate to get rid of mine because they were more expensive than the ones I can get at
Walmart, but the truth is, they just don't work. I'm going back to the plain old bristle brushes.
I'm happy you posted pixie, because, like you, I was thinking...how would I explain this to her. It's like the bristles need to be longer or something. I think because the handle is long (unlike the rubba scrubba) that you can get enough force behind it to really scrub.
