UP TO A MONTH OF HANDS-FREE CLEANING AND MAINTENANCE: The robot automatically empties debris into the 60-day-capacity bin, automatically refills its own water tank for up to 30 days, and washes and dries the mopping pad after every clean. 5 INTELLIGENT POWERDETECT CLEANING TECHNOLOGIES: Five powerful cleaning technologies help to target hidden debris, stuck-on stains, edges and to optimize cleaning for every floor type, handling the toughest cleaning challenges. UP TO 2X BETTER CLEANING COVERAGE*: With NeverStuck Technology, the robot lifts itself over obstacles and across thresholds. When mopping, it keeps the pad above carpets to prevent wet messes and deliver whole-home coverage. (*vs. Shark ION)
