i have DARK hard wood floors...this can be a pain in the rear with 4 kids. i used to get my mop out, grab the Boni...spray the floor, mop, mop, mop, rinse out the mop..repeat process. well, after talking to some friends, and seeing some pretty "great" infomercials. i was convinced this would change my life, and it HAS!! my sister and i are now totally hooked. it is so simple to use, and there are no harsh chemicals. just recently i got the hand shark steamer..and, i must say i do love!
