Maybe not this exact model, but 20 years ago when I was a young gun in college for the first time, I got one of these because I hated cleaning the fucking shower and tub.

It worked about as badly as you'd expect. I don't know if modern versions are any better, but holy shit they're a lot more expensive than they used to be. I remember spending like $40 at the time.

I quickly learned to just wipe down the shower after use and clean it more often. Thing was fucking worthless.
