iRobot takes orders for it's new floor washing robot Scooba.

iRobot sells the Scooba for $399.99 with free shipping and a 30 day risk free trial.
Only issue is that the delivery time is 8-10 weeks.

The Scooba features a four stage cleaning process in a single pass. It vacuums, washes, scrubs and dries floors automatically. iRobot announced the Scooba robot back in May. I think the Scooba has what it takes to be as successful as the Roomba.
The iRobot Scooba package contains:
iRobot Scooba Floor Washing Robot
8 oz bottle of Clorox solution
Measuring Cup
Charging Brick
Charging Base
Battery
1 Virtual Wall® (requires 2 D Batteries not included)
