Amazon is hosting a Prime Big Deal Days sales event today and tomorrow, featuring some of the best discounts we've seen all year. One of them, the iRobot Roomba Plus 405 Combo , offers a self-emptying, self-washing robot vacuum and mop at a 50% discount, bringing its price down to $400.
The Plus 405 is part of the latest Roomba lineup that iRobot has released, and it is one of the company's most capable. You can use it with the new Roomba Home app, which allows you to customize maps, suction levels, cleaning sessions, and set your robot to revisit high-traffic areas.

The Roomba Plus 405 is a LiDAR-powered robot vacuum that features dual spinning mop pads. It can detect carpet and automatically lift its mops so it doesn't get your soft flooring surfaces wet. When it returns to the dock, the robot empties the contents of its dustbin into a dustbag, which can hold up to 75 days' worth of debris.
The mop pads are also automatically washed at the dock, which iRobot claims can go up to four weeks without needing to be refilled. SmartScrub delivers up to twice the scrubbing power of this Roomba's predecessors, and the robot can intelligently detect high-traffic areas to clean them twice.
For navigation, this Roomba utilizes ClearView LiDAR, an iRobot technology that enables the robot to create a map of your home in just a matter of minutes. This also helps the robot effectively avoid furniture and obstacles on the floor, which means you won't have to rescue it each time its roller brush gets stuck on a charging cord.
I've tested a couple of robot vacuums from iRobot's newest catalog and I like how they're more efficient and accurate than older models, so I wholeheartedly recommend the iRobot Roomba Plus 405 , especially at a whopping 50% off.
