    iRobot Roomba S9+ Vacuum Cleaner
    Roomba S9+

    If you’re after the maximum pickup that a robot can offer, the Roomba s9+  (and s9, which is similar, but without its own dustbin that it self-disposes into) should definitely be on your shortlist, according to our lab tests. Like most other robot vacuums that cost more than $350, the s9+ can learn the layout of your home, and you can then use a smartphone app (or voice assistant) to tell it where and when to clean. While it navigated quite well around the obstacles in our lab tests, a staffer found that it had a few quirks in his own home, like being prone to getting snarled on the edges of rugs. This robot vac uses a  20 V Li-ion battery and is equipped with 1 side brush. It also comes with an extra filter.
