The ECOVACS OMNI station provides a completely automated solution for the best hands-free cleaning. It uses a big dust bag that can hold dust for up to 90 days and cleans itself by washing wipes in hot water at 131°F. In order to avoid offensive odors, it also uses hot air to dry the mop after every use and replenishes the robot's integrated water tank with clean water to cover up to 4300 square feet (400 square meters). 8000Pa Strong Suction with Extra-Long Roller Brush: For more effective cleaning, Ecovacs has a longer main rubber brush that measures 200mm. Its rubber construction reduces hair entanglement and, when paired with its strong 8000Pa suction, allows it to quickly and efficiently gather dust, hair, and crumbs from carpets and hard floors alike. Perfect for pet-owning households. 15mm Auto Intelligent
