The one and only one you will need for cleaning your floors in your home. Huvi is one hard working cleaning robot. It has a HEPA 13 filter that traps almost anything up to 99.5% Comes packing with  a UVC  which is a plus and a half! Sends + and - ions in the air to neutralize and picked them up as it cleans. It picks up really easy and leaves nothing behind with one pass. The Wi-Fi connection is very strong and doesn't lose connection while moving through out the house. The app is very easy to use and you can use it with Alexa or google! and best of all the one thing we like very much was the fresh home scent diffuser. As  Huvi Robot  cleans it gives gentle fragrance thought out its path. This will be our one and only ever cleaning robot thanks Kalorik for creating the one and only Huvi!
