If you've been looking to buy a robot vacuum for yourself, or you know someone who would love to receive one as a gift this holiday season, Amazon's October Prime Day has a number of deals you'll want to check out. Big sale events like this one are a good time to shop for big-ticket items like robot vacuums, because you can usually find premium models at close to record-low prices. And affordable models aren't excluded either, so you could pick up a budget-friendly robot vacuum for even less. Here are the best robot vacuum deals we found for October Prime Day.

iRobot Roomba 694

iRobot's Roomba 694 has dropped to $199 for Prime Day. It's our favorite cheap robot vacuum thanks to its strong suction power, attractive design and easy to use app. It'll be a good option for robo-vac novices, or anyone that doesn't want to fuss too much with an automatic dirt sucker. It clears hard and carpeted floors well, and it automatically returns to its base once a cleaning job is finished so it can recharge.

iRobot Roomba s9+

The premium Roomba s9+ is on sale for $600 right now, if you have Prime. It's the most expensive model that iRobot makes, and it's currently one of our favorite high-end robo-vacs. Most people don't need something this advanced, but it's hard to deny how well this machine sucks up dirt and debris, and it doesn't choke up at the first sign of pet hair either. It also comes with a self-emptying base, so when it returns after each job to recharge, it will empty its dustbin into the base — no human interaction required.

Shark 2-in-1 robot vacuum and mop

Shark's 2-in-1 robot vacuum and mop machine is on sale for $400 right now, which is nearly half off its regular price. If you're looking for a robot that can thoroughly vacuum and give hard floors a good scrub with water and cleaning solution, this is a good pick. As a vacuum, it has strong suction power and decent obstacle avoidance. As a mop, it uses its reservoir and attached cloth to get rid of messier grime and stains. It also comes with a self-emptying base for the vacuum only that the machine will empty its dustbin into after every vacuuming job.

Shark AI Ultra robot vacuum

One of our favorite robot vacuums at the moment, Shark's AI Ultra is on sale for $403. It's just as easy to use and effective as a similar Roomba, but you can often find it at a notably cheaper price point. It cleans hard and carpeted floors well, and it has a bagless, self-emptying base, which is great because you will not have to continuously purchase proprietary bags over time to keep using it.
