OMG, I it. It's a dry floor vac/ wet mop combo. First I use it to vacuum everything up off my tile and then fill the cleaning solution chamber w/ water and a little solution and then "mop" the floor. It squeegys the floor and sucks all the excess water back in. My floor has never been so clean. It works great on my friend's hard wood floors too. I know I sound like a commercial, but it's the coolest!
I think I payed $120 at Linens and Things w/ the 20% discount coupon that comes in the Sunday paper. They have them pretty much everywhere vacuums are sold, though. So worth the $$$.
