As always, robot vacuums have been one of the stars of the Prime Day show.

The sale has been the perfect excuse to upgrade, but without spending as much as you would normally. And right now, there's still a great deal on the iRobot Roomba 415X. It's a vacuum and mop combo, and it's currently $400 off. Yes, you read it right. This has taken the price down to $399.99, its best-ever price according to camelcamelcamel.

Combining 20,000Pa of suction with DualClean mop pads, this robot vacuum gives you incredibly clean floors, with dust and dirt standing no chance. The SmartScrub feature applies extra pressure to break down dried-on dirt like food spills and muddy footprints.

It's even capable of handling homes with pets, thanks to its tangle-free rubber brushes that handle hair without needing to be constantly untangled. Plus, the AutoWash Dock keeps things hygienic by washing and heat-drying mop pads after every run, automatically emptying debris for up to 90 days and refilling water so you don’t have to think about upkeep.

You can find this robot vacuum deal at Amazon right now.
