If you’ve been meaning to give robot vacuums a try, this deal on the iRobot Roomba Plus 405 Combo Robot Vacuum and Mop might be worth checking out. Right now, this deep-cleaning gadget is a whopping 50% off, bringing its $799.99 sticker price down to $399.

After sucking up dust and debris, the device's mop pads take over to wash away anything leftover. Throughout each mopping session, the pads are continuously rinsed and refreshed. The dock helps keep the device maintained, giving you about 75 days of use before you need to change the bag in the dock and four weeks before you need to refill the mop water. The iRobot Roomba Plus 405 also includes LiDAR to map out each room in your home, so as to avoid any possible obstacles, like a sleeping pet or a staircase.

With the Roomba's companion app, you can modify the device's four cleaning modes, customize how the floors in each room are cleaned, and get intel on which floors might need extra scrubbing. While the iRobot Roomba Plus 405 only comes with one extra "AutoEmpty" bag and one extra set of mop pads, a box of 26 replacement bags is available for $27.98, down from $31.99—and an eight-pack of mop pads is slightly discounted too.
