The Roomba Combo™ j5+ robot vacuum & mop is designed for both wet and dry floor cleaning—converting our most popular Roomba® j7+ vacuum to a vacuum & mop solution with the simple switch of a bin. Unleash powerful, accurate cleaning when, where, and how you want. The Roomba Combo™ j5+ robot vacuum and mop packs not only Power-Lifting Suction, but also unique intelligence that learns your home and your routines to give you custom cleaning control. With PrecisionVision navigation, your robot knows to avoid objects like pet waste, cords, socks, and shoes for worry-free cleaning.

• POWERFUL PERFORMANCE. POWERFUL PICKUP. Experience a comprehensive clean with the powerful 4-Stage Cleaning System that pulls in dirt, debris, and pet hair from wherever it hides.​
• FOCUSES ON THE DIRT. Proprietary Dirt Detect Technology allows the Roomba Combo j5 plus robot to detect dirtier areas of your home and clean them more thoroughly when the Vacuum Bin is installed.
• AUTOMATICALLY EMPTIES ITS BIN ON ITS OWN FOR UP TO 60 days. Cleans up after itself, emptying its Vacuum Bin into a convenient enclosed bag that holds up to 60 days of debris, which means two whole months of not thinking about vacuuming.
• IT DOESN’T JUST LEARN YOUR HOME; IT REACTS TO IT IN REAL TIME. With PrecisionVision Navigation and a camera, your robot identifies and avoids obstacles of all sizes like pet waste, charging cords, socks and shoes to get the whole job done.
• PET MESSES HAPPEN. P.O.O.P. (Pet Owner Official Promise)* means your Roomba Combo j5 plus robot vacuum and mop will steer clear of your pet’s waste. If it doesn’t, we'll replace your robot for free.​ *Additional terms and conditions apply – see iRobot website for full details.​
• VACUUM WHEN YOU WANT, MOP WHEN YOU WANT. Just use the added Roomba Combo Bin and your robot vacuum instantly transforms into a robot vacuum and mop leaving your hard floors shiny and dust-free. ​
• GOES WHERE YOU WANT, SKIPS WHERE YOU DON’T. Use the iRobot Home App to create No Mop Zones and when the mop bin is in use, the Roomba Combo j5 plus will avoid mopping your carpets keeping them dry.​
• NEAT ROWS FOR A MORE THOROUGH CLEAN. Advanced navigation and 2 cleaning passes allows Roomba Combo robot to navigate your home in neat, efficient rows for a wall-to wall clean without missing a spot. With overlapping passes, your robot purposefully and logically cleans in parallel lines across multiple floor types.​
• A MOP DESIGNED FOR PERFORMANCE. Just fill the Roomba Combo Bin with water or a compatible cleaning solution* and the specialized microfiber pad tackles footprints, dirt, and dust. *See iRobot website for list of compatible cleaning solutions.​
