This Eufy robot vacuum is half off for Prime DayIt's now only 50 percent off and down to $140.

One of our favorite robot vacuums from Eufy, the 11S Max , has dropped to $140 thanks to Amazon Prime Day deals . That's half off its regular price and one of the best discounts we've seen.

This model earned a top spot on our list of the best budget-friendly robot vacuums . Arguably the coolest feature here is the 11S Max's thin profile, which allows it to slide under short tables and other places typical robovacs are too chonky to reach. It's also extremely quiet during use, so it can be operated at night without waking everyone up.

The vacuum automatically adapts suction power to suit different floor types. We found the obstacle avoidance here to be excellent, thanks to an included infrared sensor. It also ships with a remote control for those who want to ensure certain parts of the home get extra attention.

ADVERTISEMENTAdvertisement This is a budget robovac, so there are some tradeoffs. First of all, it doesn't connect to WiFi and there's no affiliated app. It doesn't really need it, as the obstacle avoidance tech gets the job done, but this does mean that owners can't set schedules or create maps with no-go zones.

Finally, it's just a vacuum. There's no mop here and it doesn't ship with a debris canister. It'll have to get emptied after every use. Still, the price is certainly right.
