The premium vacuum and mop solution like no other. It’s the only 2-in-1 with D.R.I. (Dry Rug Intelligence) means the Roomba Combo j7+ uses carpet detection and the Auto Retract Mopping System 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 with added pressure for a thorough clean. It's all designed to keep your carpet and hard floors cleaner while avoiding obstacles at the same time—so you can live your life. ​
