At $399.99 for a limited time, this is the lowest-ever price for the iRobot Roomba Plus 405 Combo according to price tracker camelcamelcamel. This isn’t just another “vacuum that also mops” either; it’s a serious deep-cleaning machine with suction, scrubbing, and smart navigation that’s surprisingly advanced for the price point.

The Shark NV360 is Amazon’s Choice for upright vacuums with more than 94,000 5-star reviews. It has a detachable pod that allows you to target hard-to-reach spots under your furniture, and it’s easy to maneuver in tight corners. You can also switch seamlessly from hardwood floors to carpets thanks to its brushroll shut-off.

This is one of the best iRobot vacuums you can get. With its $799 price tag, it's prohibitively expensive. However, with this early Prime Day deal, you can save 50% off the regular price, leaving you with a high-end vacuum and mop for just $399.
