If you’ve been holding out on buying a robot vacuum because you couldn’t stomach the $500+ price tag, this deal is for you. I found a top-notch vacuum-mop combo that our Senior Shopping Reporter (and vacuum expert!), Leah Stodart, calls the “most impressive robot vacuum under $500,” for 56% off.

Right now, the 3i G10+ robot vacuum and mop combo is on sale for $199.99, down from $449.99. That’s a 56% discount or $250 in savings. It’s also a Black-Friday-level price.

The reason this one is a must-buy is the features you get for the price. The 3i G10+ uses patented debris compression that packs dirt quietly into the 1L dustbin, so you’ll get 60 days of hands-free cleaning without a huge, bulky self-empty dock. (You can store the unit under your bed, a chair, or wherever else, which is a big win for small apartments.)

It also has 18,000 Pa of suction power, which is only 2,000 Pa less than a $1,600 Roborock model — that’s seriously high suction for this price range. Plus, you get a full suite of flagship-level tech: smart mapping with LiDAR, obstacle avoidance that steers around socks and pet messes, and even a livestream camera for checking on pets (a feature usually seen on vacuums over $1,000).
