Automate your vacuuming and mopping with 400 off the Roomba Combo J9

If you're looking to automate more of your home cleaning setup, iRobot's flagship Roomba Combo J9 is on sale for 400 off. The vacuum-mop hybrid robot, which only arrived last fall, has a redesigned dock that automatically empties debris and refills the device's mopping liquid. Take 400 off the vacuum-mop hybrid. The Combo J9, Engadget's pick for the best vacuuming-mopping robot, has an upgraded motor and four-stage cleaning system that takes multiple pass-throughs across your carpets and floors. This version also adds dual rubber brushes for better suction and pressurized scrubbing. Its motor automatically lifts the mop pads when it reaches carpets and rugs to help keep them dry.
