Traditional mopping means hours spent pushing the same bucket of gray water from room to room. The iRobot Roomba Electro Plus 5-in-1 Vacuum/Mop Disinfecting Hard Floor Cleaner ends that routine by lifting dry debris and washing the floor in a single self-propelled pass, then cleaning its own roller between jobs. Fill the tank with plain tap water, and the machine makes its own disinfecting solution as it works. Because no chemicals are needed, you can feel safe running it in the kitchen where toddlers play or the hallway where pets nap, with no lingering odors or residues. Key Features and Benefits of the iRobot Roomba Electro Plus 5-in-1 Vacuum/Mop Disinfecting Hard Floor Cleaner Chemical-Free Disinfecting: Electrolyzed tap water forms a dual-action solution that kills 99.99 percent of germs, including bacteria and fungi, so no bottled cleaner is needed. PowerSpin Roller: The roller mop washes and rinses itself as it spins while suction lifts dry debris, leaving a streak-free, tangle-free pass behind you. ThermaClean Dock: The dock heat-washes, sanitizes, and heat-dries the roller after every run, so you never have to wring out an old roller by hand. Runtime and Range: Up to 35 minutes of cordless run time covers up to 1,292 square feet, enough for most main floors on a single charge. Electric Brushroll: The electric-powered brushroll picks pet hair and fine grit off bare floors rather than leaving the work to suction alone. Dirt Detect: Dirt Detect sensing technology flags heavier soil loads under the machine so you know when to hold position until the spot clears. Self-Propelled Drive: Powered forward motion pulls the cleaner along, and at 9 pounds it stays easy to steer around chair legs and appliance corners. Will It Work on Your Floors? Sealed hardwood, tile, laminate, stone, and vinyl are all listed as safe surfaces, so a home with a mix of them needs only this machine. It is not designed to clean carpet, so plan to keep area rugs and carpeted rooms out of its path or lift the rugs before you start. Sylvane's Expert Take If you have a home that is mostly tile and sealed hardwood and you're tired of juggling a vacuum and mop, this is the machine that replaces all of them in a single pass. What separates it from other mopping systems is the chemical-free disinfection system, so keeping floors sanitized costs you water and electricity, instead of cleaning solution. We also appreciate the ThermaClean dock, and how it heat-washes and dries the brush roller for you, rather than leaving a damp mop head to deal with later.
