iRobot's Roomba s9+ robot vacuum is down to its best price yet

The high-end Roomba s9+ may normally be too expensive for most people to justify spending on a robot vacuum, but a one-day-only deal has shaved the price nearly in half, bringing it down to an all time low of $500. If you've been holding off on buying the premium model, which we ranked as one of the best robot vacuums out there, now's the time to scoop it up.

The Roomba s9+ is a splurge in every sense of the word, and boasts 40x the suction power of iRobot's more basic vacuums. Its 1.5-foot-tall self-emptying base holds up to 60 days worth of waste. And with a sleek, black and copper design, it isn't an eyesore. The s9+ is D-shaped, as opposed to being fully circular, meaning its flat edge can more effectively get into corners. We found the s9+ paired quickly with WiFi and the iRobot app for an easy setup, and wasn't unreasonably loud when it emptied its bin.

The vacuum works on carpets and hard floors, and has multi-surface rubber brushes to handle more difficult types of debris, like hair. It also promises to filter out microscopic particles and allergens like those that might be accumulating around the house from your pets. But, while it's meant to excel at cleaning up pet hair, its sensors aren't made for spotting and avoiding pet poop. It does, however, have Careful Driver" technology to avoid slamming into objects while it cleans. At the current discount, the s9+ offers premium cleaning power at a mid-range price.
