I am absolutely blown away with the performance of this vacuum, who is now known as Hazel! The set-up is very easy. Connecting to my WiFi threw me a little bit (probably operator error), but once connected and the unit charged, you'll find the app is very user friendly. I closed off 2 carpeted bedrooms, one of which is a never-used guest room and the other a carpeted "junk room". (Hazel would never have found her way out of there!) I did not do any vacuuming, sweeping, mopping or anything beforehand, because I wanted to have some debris to test her. Initially she mapped the house, which is pretty amazing in itself. Then I ran the first job which was also amazing to watch, because she meticulously covered every square inch. The majority of my place is hardwood floors, and I have a 5' X 7' short-nap area rug in my den. She does this little "dance" thing along the baseboards and in the corners to grab any debris with the edge brush. Then she began straight-line maneuvers, spinning around at the end of each row to head in the opposite direction overlapping the previous row and vacuumed literally every piece of ANYTHING in her way (kitty litter, cat hair, my medium-length hair and just plain dirt and dust). 741 square feet later, which took 1 hour, 4 minutes, the hardwood floors looked great. I wasn't really pleased with the area rug in the den, so I did a "spot cleaning" and changed the suction level to "strong". It consisted of 24 square feet, took 2 minutes to complete and it looks great. I will be telling everyone about Hazel. The only downfall ...... Snookie and Louie are terrified of her! We'll see how long it takes them to get to know her.
