Welcome to Home Appliance Review; This is our Eufy 11s Max review. The robot’s airflow was measured at 17 CFM; its suction was measured at 1.36 kPa.
Eufy 11s Max tests
In our carpet stress test, the Eufy BoostIQ RoboVac 11s Max picked up all debris types very well. This robot has a fairly narrow direct cleaning path, as this brushroll compartment is only 5.75 inches wide. But with the help of its side brushes and repeated movement over the same area, it was able to clean up well in this test.
Carpet deep cleaning
Over time in our carpet deep clean test, the 11s max picked up only 4 grams of debris after three passes over an area of carpet embedded with 30 grams of fine debris.
Hard floor cleaning
In our hard floor stress test, the 11s max once again picked up all debris types very well. Again, the robot doesn’t pick up all debris on a single pass, but with repeated movement over the same area, it does pick up most debris eventually.
The 11s max performed very well cleaning edges. This robot utilizes random padding to move around when cleaning, and this pathing allows it to approach a lot of edges head-on, which is good for cleaning them. It also does this back and forth movement against edges, which is especially effective for cleaning them.
In our robot vacuum crevice test, the 11s max did not perform well on default power. It did perform better on maximum power, but even after extensive runtime, it still could not pull most of the debris out of the crevice used for this test.
Human long hair test
In our human hair pickup test, the 11s max picked up all the hair, but most of that hair wasn’t pulled into its dustbin. More than 90 percent of the hair it picked up tangled around its side brushes and around its brush roll and had to be cleaned off manually.
Pet hair test
In our pet hair pickup test, the 11s max performed much better. It picked up and collected all of the shorter pet hair used for this test in its dustbin.
Navigation & coverage
We tested the robot’s cleaning efficiency and coverage in two different environments: an empty room and a cluttered room. In our empty room testing, we see the 11s max’s random cleaning pattern demonstrated quite well. We can also see it getting very even coverage across the whole room.
In our cluttered room testing, we again see the same random cleaning pattern, this time around a variety of different obstacles. We again see mostly even coverage across the room. The only area the robot doesn’t cover initially is this area towards the bottom and towards the right underneath the chair frame. Though it does get coverage over this area eventually as the test continues on.
Other important specifications
Battery life, dust bin volume, noise output, climbing threshold, and dimensions:
Other important specifications and test results we considered for this review are summarized here. Note especially how there are no boundary accessories like a magnetic strip, for example, included with the 11s max or available for purchase separately. Also note the 11s max’s runtime, bin volume, and noise output, and how those specifications and test results compare to the average for all of the random padding robots we’ve tested so far. Lastly, note the robot’s diameter and height. These dimensions make the Eufy 11s Max one of the smaller robot vacuums we’ve tested.
Pros and cons of Eufy 11s Max
Moving on to what we like and dislike about this vacuum.
First, let’s talk about what we like. The Eufy 11s Max offers high airflow and especially high tested suction for a robot vacuum in its price range. It offers good general pickup ability. It has very good edge performance, especially because of the back and forth movement it does against edges.
It picks up pet hair very well according to our testing. It has solid battery life and a good size dustbin for a robot vacuum in its price range. It’s slightly quieter than the average robot vacuum we tested, and it’s considerably smaller and not nearly as tall as most top-rated mapping robots.
Moving on to what we dislike about the Eufy BoostIQ RoboVac 11s Max.
It offers disappointing deep clean performance, especially considering its high airflow and suction. It struggles pulling longer hair into its dustbin; most longer hair tangles around its brush roll. We also don’t like the fact that there aren’t any boundary accessories even available for purchase separately for this vacuum.
Eufy BoostIQ RoboVac 11s Max vs 11S
In order to make general recommendations, let’s first compare the 11s max to the 11s. Compared to the 11s, the Eufy 11s Max is the same size with the same size dustbin, the same navigation system, the same battery life, and the same noise output. The Eufy BoostIQ RoboVac 11s Max does look slightly different with a different filter, and it also offers better raw performance, that is to say, higher tested airflow and suction than the 11s. But we didn’t really see this translate into any better real-world performance. In other words, the 11s max really doesn’t pick up debris any better than the 11s despite having more raw power.
The bottom line here is that the only substantial difference between the Eufy BoostIQ RoboVac 11s Max and the 11s is price. So between the two, Home Appliance Review recommend you buy whichever model you can find cheaper, which is usually the 11s, not the Eufy 11s Max.
Compared to other budget robot vacuums on the market, Eufy BoostIQ RoboVac 11s Max and 11s max are some of the best such robots we tested. Both offer terrific performance for the price, and you really can’t go wrong buying either one of them if you’re shopping for a budget-priced robot vacuum. Which one we recommend you buy today really just depends on the current pricing. And again, we recommend you buy whichever one is cheaper right now.
