The only thing better than a robot that vacuums for you is one that empties its own dust tray, too. The popular Shark AI Ultra robovac, which is normally a hard-to-swallow 600, is half off for Prime Day, bringing the cost down to just 295. You can control this vacuum with voice commands -- it supports both Amazon's Alexa and Google Assistant -- and it uses Matrix Clean Navigation to make sure it hits every spot in your home. This Shark AI Ultra is a version of one of our favorite robot vacuums, and comes with a bagless, self-emptying base that holds up to 60 days' worth of dirt and debris. It's made to tackle even the daily accumulation of pet hair, with powerful suction and a self-cleaning brushroll that has an anti-hair wrap to prevent tangling.

Robot vacuums are some of the pricier smart home gadgets you can get, which is why waiting until a sale like Amazon Prime Day is a smart shopping move.

It's always a good idea to look for discounts on big-ticket items on Prime Day, and robot vacuums are no exception. These machines can be some of the most expensive gadgets you buy for your home, with high-end models costing close to (or more than) $1,000 normally. Thankfully, Prime Day is a good time to pick up a robo-vac for much less than that since premium models tend to be hundreds of dollars off, and even those that already have budget-friendly prices are also often discounted. Here are the best robot vacuum Prime Day deals we could find on all of our favorite machines. The iRobot Roomba 694 has dropped to $199 for Prime Day.
