SAVE OVER $400: As of July 29, the iRobot Roomba Plus 405 is on sale for $398 at Amazon. That's a 50% discount on the list price.

iRobot is one of the best-known names in robot vacuums, and for good reason. The brand is synonymous with effective devices that automate one of life's most arduous chores.

If you've been looking for a good deal before purchasing your own iRobot, Amazon has a great deal on the iRobot Roomba Plus 405. Not only is it currently 50% off at $398 (a total discount of $401.99), but it is also the best-ever price for this vacuum.

This is a robot vacuum and mop combo designed to tackle everyday dirt and spills. It uses DualClean Mop Pads, SmartScrub technology, a multi-surface rubber brush, and an edge-sweeping brush to clean across different floor types. And for deeper floor cleaning, the spinning DualClean Mop Pads apply downward pressure, and SmartScrub technology gives more thorough scrubbing to help remove tougher messes.

It also works with very little effort from you. For example, its navigation is handled by ClearView LiDAR navigation. This allows the vacuum to map your home quickly, plan efficient cleaning routes, and avoid obstacles, while sensors help prevent falls down stairs. Also, it has an AutoWash Dock that automatically empties the dustbin for up to 75 days, washes and dries the mop pads, and keeps them refreshed to ensure efficient mopping.

Say goodbye to manual floor cleaning for good with this iRobot deal at Amazon.
