The eufy RoboVac 11S Max scored 97% in cleaning tests, which is a lot of performance for the price. Reviewers praised the 2000 Pa suction with BoostIQ technology, the 100-minute runtime, and how quietly it runs. At 2.85 inches tall it slides under low furniture other robots can't reach. There's no app control and no digital mapping, and running max mode cuts the runtime sharply. Budget-conscious buyers who want reliable basic vacuuming are the fit; anyone after advanced smart features isn't.
Full review
Strong on hardwood, ordinary on carpet
The 11S Max leans on 2000 Pa of suction with BoostIQ, which steps the power up within about 1.5 seconds when the floor demands it, and on hard floors that combination does the job. TechGearLab scored its carpet cleaning 6.8 out of 10, below average for the category, and fine debris pressed into pile is where it visibly struggles. Pet hair is the other soft spot, so households with shedding animals should treat it as a supplement to a proper vacuum rather than a replacement.
Bump-and-turn navigation with no map
There is no camera, no lidar and no map. The robot drives until it hits something, turns and carries on, and TechGearLab called the result clumsy and prone to missing spots on a single run. Cords and loose clothing will stop it, so a quick tidy before each run is part of the routine. The upside of the simplicity is a 2.85-inch body that clears furniture taller robots cannot get under.
Quiet, slim, and nothing to install on your phone
Noise is genuinely low, around 55 decibels, quiet enough to run while someone is in the room. Dad Blog UK's John Adams found the charging base felt light and cheap even though it worked, and the 0.6-litre bin fills quickly in a family home. Control is by remote only: there is no app and no WiFi, so scheduling happens on the unit itself and there are no no-go zones to draw.
A first robot vacuum rather than a last one
Running the highest power setting cuts sharply into the 100-minute runtime, so the practical configuration is standard mode plus BoostIQ. For a home that is mostly hard floors and wants a daily sweep without configuring anything, this is a lot of vacuum for the money. Anyone who wants mapping, zone cleaning or app control is shopping in a different bracket and should decide that before buying.
Strengths
- +2000 Pa suction power with BoostIQ technology that automatically increases suction when needed
- +100-minute runtime on hardwood floors
- +2.85-inch slim profile for navigating under low furniture
- +self-charging capability with automatic return to charging dock
- +quiet operation comparable to a standard microwave
Watch-outs
- −Lacks digital mapping for advanced navigation
- −No compatible smartphone apps for remote control
How it compares
The eufy RoboVac 11S Max stands out for its 2000 Pa suction power and BoostIQ technology, which automatically increases suction when needed—a feature not found in the Lefant M210 or iRobot Roomba i3 EVO. However, it lacks digital mapping and smartphone app control, unlike the Roborock Q5 Pro and Tapo RV30 Max, and its max mode significantly reduces runtime.
Rating sources
Counts as 3.24/5 in our score — this publisher's 138 scores on the site average 3.66, so its scores are adjusted up to compare fairly with other publishers.
“The RoboVac 11S features powerful suction capabilities of 1300 Pa. To be honest, I didn't know what 'Pa' was at first, but it turns out, it means this little guy can suck up debris like nobody's business.”
“I'm quite surprised at how the 11s has changed our behaviour as a family. I take it easy on the sofa while the robovac does the hard work.”
Our 3.2 score is the average of the 1 scored review above, each adjusted for how strictly its publisher scores; 2 more reviewed it without printing a score and are not in the average. More about methodology.
