The DEEBOT combines a comprehensive cleaning system with innovative technology for a more thorough and efficient clean. That means less chores and more free time for you. The DEEBOT uses Smart Motion to clean both carpet and hard surface floors. When in Hard floor cleaning mode, the DEEBOT follows a systematic, back-and-forth cleaning path allowing it to clean more thoroughly, efficiently and cover a larger cleaning area. Tackle those particularly problematic messes by engaging the Max Mode cleaning function. It increases suction power up to 2 times, and works on both hard surface floors and carpets.
