If you've been shopping around for a robot vacuum, you'll have come across Roomba. They're one of the most popular brands (despite their struggles), and not without reason. This model offers dual vacuum and mopping features. It has seriously powerful suction, strong enough to lift dirt of all kinds. You also get four suction levels, repeat-pass options, SmartScrub deep scrubbing, Clean Zones for targeted areas, and Keep Out Zones for restricted spaces, so you can clean exactly the way you want.

This model uses DualClean spinning mop pads and SmartScrub to apply pressure and tackle tough stains much more easily. It can mop with either water or a cleaning solution, and the pads automatically lift when the vacuum detects carpet. The AutoWash dock then washes, dries, and refreshes the mop pads so they’re ready for the next use, with nothing for you to do.

This robot vacuum deal has a limited-time stamp, so grab it from Amazon now.
