With two small kids and no dog, our wood floors are always a mess. I was delighted when I received my Scooba -- I could now conquer the floor!
Scooba is a great little robot that vacuums the floor, sprays cleaning solution, then squeegees it up -- really cleaning your floor for you. All you have to do is keep it charged, add the cleaning solution, and empty it when it's done. It maneuvers around and under furniture, getting to places I know I wouldn't bother getting to.
While many have criticised Scooba for having only one choice for a cleaning solution (a Clorox product that is perfectly safe for wood floors), I don't mind not having to dwell over which one to buy. It has simplified my life, and keeps my floors clean. I am happy!
