• THE WORLD’S MOST ADVANCED ROBOT VACUUM AND MOP COMBO – Introducing Roomba Combo j7+, the only vacuum and mop robot that seamlessly transitions from carpet to hard floors and vacuums and mops in the same mission without any intervention from you. It cleans your home without avoiding carpets or requiring you to change cleaning modes.
• KNOWS WHEN TO MOP AND WHEN TO VACUUM – On hard floors, it mops and vacuums at the same time. On carpet, it lifts its mop pad safely away and continues with powerful vacuuming avoiding wet carpet messes.
• CLEANS WHERE YOU WANT, WHEN YOU WANT – You can set specific cleaning preferences by room: For instance, set it to vacuum the living room, then vacuum and mop the kitchen. You can also choose how much liquid the mop should use by room.
• THE ONLY MOP THAT KEEPS CARPET DRY – Most robot vacuum and mop combos don’t lift at all, resulting in wet carpet messes. But ours completely lifts its mop pad up to the top of the robot, safely away from carpet.
• ADVANCED 4-STAGE CLEANING – It combines our first-of-its-kind mopping, edge-Sweeping Brush, Dual Multi-Surface Rubber Brushes, and Power-Lifting Suction to deliver an incredible clean on carpets and hard floors.
• KNOWS EXACTLY WHAT TO AVOID – iRobot OS is thoughtfully intelligent, enabling it to recognize (original word was detect) and avoid obstacles like, clothes, shoes, towels, and even pet waste (seriously).
• AVOIDS PET ACCIDENTS ON PURPOSE – WE GUARANTEE IT – Only iRobot brings you P.O.O.P. (Pet Owner Official Promise). You can rely on your Roomba Combo j7+ to avoid pet waste, or we’ll replace it for free. Additional terms and conditions apply – see iRobot for full details.
