iRobot launches a $1,399 premium Roomba combo vacuum/mop and dock
The premium vacuum and mop solution like no other. It's the only 2-in-1 with a mop that lifts itself to the top of the robot, completely away from carpet preventing wet messes entirely. On hard floors, it vacuums and mops at the same time. The 4-stage cleaning system combines our edge-sweeping brush, dual multi-surface rubber brushes, power-lifting suction, and first-of-its-kind mopping.
