I received this Kalorik Home HUVI Robot Vacuum to try and it's pretty cool. This vacuum is easy to set up for use straight out of the box (not referring to connecting to app) and charges pretty quickly. I was so impressed my first time using it as it picked up a lot more than I was able to see and the results were great. It's a decent size as it goes under my couches and chairs with ease, not getting stuck. It goes over the door jams in my rooms as well with no problem. The only problem it gave me was with my very fluffy round area rug. It seems to get stuck on that, but works well with the area rug in the living room as it's not as fluffy. Overall, I  like this robot vacuum. I have been using it quite often and I'm enjoying every minute.
