Best robot vacuums according to reviews

At the cheapest end of the spectrum you’ll find this option from Housmile, which received 5 out of 5 stars by 85% of its reviewers on Amazon. Unlike other vacuums that require a docking station, this one has a simple charging cord, and one charging session can give it enough juice for 30 minutes of vacuuming. What you sacrifice at a cheaper price point are things like room scanning technology and a mobile app, but for someone who isn’t that much of a techie but wants to get in on the robot vacuum hype, this is a good option. (And it makes a great gift for grandma.)
