If a robot vacuum has been on your wishlist for a while, chances are you've come across the name Roomba. And with Prime Day around the corner, we're already seeing discounts on almost every single new Roomba.

As of July 3, the iRobot Roomba Plus 405 is on sale for $399.99. This deal saves you $400 on list price, and is the lowest-ever price according to camelcamelcamel. Our robot vacuum expert has hand-picked this deal as one of the best ahead of Prime Day.

And for under $400, you're getting a lot. It has seriously powerful suction, as well as intense cleaning with its dual mop pads and SmartScrub tech. It even has a rubber brush that works across surfaces alongside an edge-sweeping brush to get right into corners. The dual mop pads also spin and create a downward pressure scrub, so even the hardest of messes are no problem.

And it can map out your home quickly and efficiently with ClearView LiDAR, avoiding stairs and navigating around any obstacles.

You can control everything in the Roomba app; just open it up to schedule routines, check filter health, or tell it to focus on certain rooms. You can choose between vacuuming, mopping, combo cleaning, or vacuuming before mopping, and the mop pads lift automatically when your carpet is detected. All from the push of a (smartphone) button.

You can find this incredible deal at Amazon now.
