I am extremely suprised in a good way with this product, easy to navigate the app,it comes with a charging station so do not need to worry about the battery, it as a Uv function that destroys and disinfects the contents inside the dust container, a hepa filter  medical grade that leaves my house free of airborne particles, bipolar ionization that provides me cleaner air and aroma diffuser that fills my house with a pleasant fragrance, it allows me  me to regulate suction power,schedule cleanings and not only opt for a spot cleaning but also wall follow which is amazing and insures a thorough cleaning. 
The most complete and efficient robot vacuum I have ever seen.
