We chose to test the Eufy RoboVac 11S as our budget model to see what you would get in a robot vacuum at a low price point. It does not have any advanced navigation system, and there is no app nor any smart features. We felt that the Eufy would give us a baseline for what a low-cost robot vacuum was capable of.
- Good value
- Easy to use and operate
- Decent suction power on both hard and soft surfaces
- Quietest robot in our test
- Random navigation
- No obstacle recognition
- No mapping feature

As a basic robot vacuum, the Eufy has only a rudimentary “bump and run” navigation system that is based on a mapping algorithm, a bump sensor, and infrared sensors. This type of navigation was common on most robot vacuums when they were first released, but now it feels dated. Especially compared to other robots we tested.
In our tests, the Eufy seemed to randomly move around until it ran into an object, and then it redirected at a perpendicular angle. This meant that it was hard to gauge how well it actually covered the entire space because it did not follow any uniform pattern. Because of the randomness, it did take longer to clean our test room than other robots with more advanced navigation technologies.
It has no object recognition, so if there is anything in its path, it will try to suck it up. This included cables, socks, and anything else that might be left on the floor.
The Eufy also struggles with “seeing” dark colors. We had a lightweight white and black tables in our test room, and it gently bumped the white table and moved around it very well, but it simply slammed into the black table moving it a few centimeters before bumping in a different direction.
The nice thing is that it does remember where its dock is, and through a combination of a mapping algorithm and infrared sensors, it is able to find its way home when it is finished cleaning or low on batteries.
It may miss some spots while cleaning, and it is hard to tell if there is any logic to its movements, but it can return back to the dock when it finishes. Because of its lack of navigation or object recognition, you need to be sure to pick up anything you don’t want the Eufy to suck up or get tangled on when you set it loose. Overall we scored it as a 2 out of 5 for navigation.
Despite its lack of navigation and smart technology, the cleaning performance of this little robot was not bad. It is rated at 1300 Pa of suction power which is the lowest-rated performer on our list, but in actual tests, it seemed to punch above its weight. One reason for this could be that it has 2 spinning brushes which are effective at feeding debris into the cleaning brush.
It features 4 cleaning modes: auto, spot, edge, and single room, and it claims to have BoostIQ which they claim automatically increases the cleaning power when needed, but we did not note any change in power. Equipped with dual rotating side brushes, these help to sweep debris from corners and hard-to-reach spots into the suction zone.
In our cleaning tests, it performed relatively well and was able to suck up most of the flour and cat litter. But because of its poor navigation, it did leave spots untouched. The suction power was also not enough to clean between the cracks in tile and hardwood floors.
It did fairly well cleaning up pet hair from carpet and was in the middle of the pack in most of our cleaning tests. We were impressed that it was able to pick up all the coins from the carpet without spitting them back out.
Overall, it is not great at cleaning, but for the price it seems to actually do an okay job, and it earned a 4/5 in our test.
Ease of use
We do like the Eufy for how easy and straightforward it is to start using right out of the box. It comes with a simple remote control, and once you plug in the dock and charge it up, using it is as easy as pushing the Autoclean button and letting it do its job.
The remote control does allow you to schedule cleaning times, but we found that the only way to reset these was to remove the batteries from the remote control.
As far as loudness goes, the Eufy is relatively quiet, reaching just 71dB at the highest setting, which is as loud as a quiet conversation.
It was able to overcome a 1cm threshold in our test, but got stuck on the 2cm. It is rated to be able to climb 16mm, and this is normal for most robots.
It has 100 minutes of run time and the manufacturer’s estimate is that it takes 5–6 hours to charge. This should be enough to completely clean an average-sized home.
The 600ml dustbin is large and easy to remove and empty. It is open at the top, so getting it completely empty just took one shake in the trash can. Other maintenance includes cleaning the brush weekly and replacing it after 6–12 months. The filter is meant to be cleaned weekly and replaced after 6 months. Other parts are stated to last 6 months or more and should be replaced after they wear out. This is fairly standard for a robot vacuum.
We rated it 4/5 for Ease of use.
While the Eufy doesn’t have many features, smart functions, or a mop, it does clean relatively well, and we think it is a decent buy at this price point. With a final score of 2.5/5, it is an average robot vacuum, but this is a decent performance for a budget brand. There are better options available, however, and you should check out our Best Robot Vacuum article to see our picks.
