The best: iRobot Roomba S9+

iRobot Roomba s9+ (9550) Robot Vacuum with Automatic Dirt Disposal-Empties Itself, Wi-Fi Connected, Smart Mapping, Powerful Suction, Corners & Edges, Ideal for Pet Hair, Black

The Roomba S9+ builds on the innovations introduced in Roomba i7+.

The Roomba S9+ received an Editor’s Choice Award from Digital Trends. Like the i7+, the S9 series is available with or without iRobot’s cool Clean Base charging station and self-emptying dust bin. There’s also a new, D-shaped body and an enhanced brush design that promises improved edge and corner cleaning, while suction is boosted forty times compared to the Roomba 600 series. You’ll also benefit from smart mapping, which allows you to select individual rooms for cleaning (as well as entire floors) and a unique anti-allergen system — a first for robot vacuums, according to iRobot — designed to trap dust and pollen.
