I own a Roomba AND a Scooba. They're both in the GARAGE. They should be in the GARBAGE. The Roomba "worked" for about a month. I quote "worked" because it picked up almost nothing, left the floor visibly dirty and then broke down. Even when it worked, it couldn't climb over the edge of an area rug, so it only traveled in a third of the room when it moved.
The Scooba worked a week longer I think. It cleaned about as much as the Roomba vacuumed and then decided to start cleaning without using any fluid. It took at least three times longer to prepare and clean up after than a bucket and mop. I bought 4 bottles of the fluid right after I got it, and I still have ALL FOUR. That's how long IT lasted! As with everything else, repair costs more than replacement, so they're both disposable.
Save the cost, irritation and clutter!
