This Eufy robot vacuum is half off before Prime Day

The Eufy 11S Max robot vacuum is on sale for $140 as part of an early Prime Day sale. That’s half off, as the typical cost is $280 for this particular model. This is extremely close to a record-low price.

This device made our list of the best budget-friendly robot vacuums. Perhaps the coolest feature here is that the 11S Max is extremely thin, so it can 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.

It runs for around 100 minutes per charge and it’ll head to the outlet on its own for some juice. 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.

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.
