OMG this thing has changed my life!! I'm serious you have no idea. Background: I live in a basement apartment with an extra tiny bathroom. There is a standup shower that's a decent size, but the entire bathroom is tile. I've cleaned in the past, but had no idea how to get into the crevices of the tile. Over the past year the grout and soap scum build up became ridiculous and I was depressed everytime I went in there. I am a busy career gal with a social life. I was embarrassed of my bathroom when company came over. Pulled out this bad boy this past weekend and went to busting up all that nasty looking black scum and grout in between the tile. I only regret I didn't take a before and after picture. My bathroom looks like new. Trust me this will be your best purchase. Even get it for someone who hates to clean. My bathroom (and the rest of the house) will be forever spotless.. Yayyyyyyyyyy!
