iRobot Roomba E5 Wi-Fi Connected Robot Vacuum Cleaner with Powerful Suction for Pet Hair, Carpets & Hard Floors - Smart Home Cleaning for Busy Families

The Roomba vacuums very well. I would give it a 5 overall if it wasn’t for inconsistency in covering the entire floor area which I estimate to be 1,400 square feet. It seems to get lost once in awhile and does not cover the entire floor area every time. The randomness of its travels I think assures it will cover the entire floor in 2 or 3 days. We run the Roomba 6 days a week. Also, our Roomba makes it back to home base half the time so we are carrying it back to the base from wherever it ran out of battery. This is not a big deal though. I also like it’s ability to get underneath a number of furniture items which we would otherwise have to move for our traditional upright vacuum. That’s a plus.Glad we bought this unit. Overall performance is worth the investment.
