We’ve tested out quite a bit of robotic vacuum cleaners, and there aren’t very many budget-friendly models out there that have stolen our hearts quite as much as the Eufy 11. We originally thought there wouldn’t be much room for improvement, but we were sorely wrong.
At first glance, the Eufy 11 and 11S MAX appear identical, but looks can be deceiving. The 11S MAX has been upgraded in several different ways, leaving the 11 in the dust and crumbs that it, on occasion, fails to pick up. Let’s take a closer look at what the disc casing houses and how it performs.

The size of the 11S MAX has been reduced to only 2.9 inches from the original 3.1-inch height of the 11 and 11+. Although a 0.2-inch difference may not seem like much, it does mean a lot when the robot needs to venture under furniture to deliver a thorough cleaning. The shorter 11S MAX has a better chance of reaching under couches and nightstands than most budget robots on the market.
The 11S MAX attacks and retains dust and other microscopic particles by passing them through three different filters. The first two stages are a large pre-filter and a washable foam filter for trapping the largest pieces. The final stage is a high-efficiency filter that traps the remaining particles. Just so you’re aware, this is not a True HEPA Filter.
Great Suction Power (for a budget robot)
The 11 and 11+ delivers a moderate 1,000 Pa of suction power – more than enough power to pick up most debris. The 11S MAX has an upgraded motor that works at 1,300 Pa. The 200-Pa difference may not seem significant, but when dealing with large-sized crumbs and carpets, you’ll be thankful for the extra boost in suction.
Low Noise Production
Despite the 11S MAX being equipped with a beefier motor compared to the 11, this unit is a lot quieter. On auto mode, it generates about 55 decibels of noise. Now, we admit that this isn’t the quietest robot vacuum in existence, and in fact, some users may find it to be downright noisy at times, but by budget-robot standards, 55 decibels is more than tolerable (60-plus decibels on the 11 and 11+).
2nd Generation BoostIQ Technology
The 11 and 11+ used the outdated Power Boost Technology that sometimes failed to detect when the robot transitioned from carpeted to smooth floors and back. The 11S MAX comes with the BoostIQ Technology – the second generation of Boost Power if you will – that does a much better job. With this, the 11S MAX automatically adjusts its suction power based on what surface it’s currently cleaning. The robot delivers more suction power when roaming onto carpets, then cranks down the power when venturing onto tiled floors.
Although the 11S MAX is rated at 100 minutes of continuous cleaning, many users have found their robots to run for much less. This drop in runtime is mainly due to the BoostIQ Technology which adjusts the robot’s suction power based on the surface it’s cleaning – the battery drains faster when the 11S MAX is cleaning carpets than tiled floors.
Even with the 100-minute runtime, you won’t need to worry about the robot running out of fuel in the middle of its vacuuming cycle. The 11S MAX has an auto-docking feature which sends the robot straight to the charger to refuel. Unfortunately, the robot doesn’t have an auto-resume function to pick up where it left off, so you’ll need to command the robot to get back to work manually.
Eufy 11S MAX in a nutshell
As you can see, the Eufy 11S MAX isn’t the most technologically advanced robot out there, but that’s OK since it’s it a part of the “budget-friendly” selection of robotic vacuums. The Eufy 11 does an admirable job at maintaining clean floors and carpets, but it is missing a lot of convenience features we’ve grown accustomed to (Amazon Echo, a downloadable app, and auto-resume function).
Eufy 11S MAX vs. Ecovacs Deebot N79W+
If you’re familiar with Ecovacs, then you are probably already aware that Eufy still has some work to do to reach the same quality and price of the Ecovacs robot vacuums.
The N79W+ is one of the more basic Deebots available. Just like the Eufy 11S, the N79W+ does not have an integrated mapping and navigation system, so it gets around by cruising freely across your floors. It has built-in sensors to keep the robot from tumbling down stairs and bumping into obstacles.
But unlike the 11S, the N79W+ does not have a suction boosting feature for carpets. This model should be used specifically on hard floors – even low-pile carpets may prove to be too difficult for this robot. This is a real shame considering how most modern robots are designed to tackle all sorts of surfaces.
The good thing about the N79W+ is its convenience. Other than the infrared remote control, users can download an app on their mobile devices to configure cleaning cycles and even move the robot around. The N79W+’s Wi-Fi connectivity makes it compatible with Alexa and Assistant. These are basic convenience features that are, for whatever reason, lacking in the 11S.
Finally, the most noteworthy thing about the N79W+ is its True HEPA Filter. This type of filter is used to trap allergens and microscopic organisms (dust mites, their eggs, and waste). The 11S has a super-fine filter, but there’s no guarantee that it will capture and retain pollen and dander. For those suffering from seasonal allergies, the N79W+ might be the better option.
Eufy 11S MAX vs. iRobot Roomba 675
Although iRobot is the current market leader in in-home robotic appliances, comparing the iRobot Roomba 675 to the Eufy 11S is a bit unfair as they both belong to different generations of robots. But even though the 675 is older, it’s still a worthy option in today’s sea of robot vacuum cleaners.
The 675 has a suction rating of 600 Pa which is less than half that of the 11S. However, this doesn’t necessarily mean it’s a bad robot. In fact, in turbo mode, the 675 can perform rather well on low-pile carpets. We’d still recommend getting this robot if you have hard floors and very little carpeted areas.
The Roomba 675 comes with a large 1,800-mAh battery that delivers up to 90 minutes of continuous cleaning. With the bot’s auto-docking feature, you won’t need to worry about it running out of fuel in the middle of a job. However, you will need to command the robot to get back to work and start its cleaning cycle from the beginning.
The 675 comes with an AeroVac filter that is similar to a True HEPA Filter but with an efficiency rating of between 70 and 80%. This filter works just about the same as Eufy 11S’ in trapping dust but works much better at trapping allergens like dust mites pollen and dander.
This robot has built-in sensors for detecting the presence of collections of dirt. Unlike the hit-and-miss Eufy 11S, this robot will go out of its way to hunt down dust.
The Roomba 675 does not come with its remote control. Instead, you’ll have to download the mobile app or use Alexa or Assistant to help you conveniently control the robot from a distance.

Eufy 11S MAX vs. ILIFE V3s Pro
The final comparison in this article is the Eufy 11S against the ILIFE V3s Pro. If there’s one comparison where the 11S is the clear winner, it’s this one. The ILIFE V3s isn’t a bad robot per se, but let’s just say that there’s room for improvement.
The V3s delivers a maximum for 850 Pa of suction power – a little bit over half that of the 11S. But the clear difference in suction power is in its performance on a carpeted surface. The V3s should not be used on carpets at all. You’ll be sorely disappointed with how much this unit fails.
On the bright side, the V3s has a pretty large battery. The 2,600-mAh Li-Ion battery allows the robot to work for 120 minutes straight before needing a 3-hour rest to charge. Afterwards, you’ll need to command the robot to get back to work since it does not have an auto-resume function.
One of the most disappointing things about the V3s is its tiny dustbin. This robot can collect only up to 300 mL of dust before stopping in its tracks. With its large 1,200-square-foot of area coverage per charge, the bin will fill up rather quickly.
Similar to the Eufy 11S, the V3s is not compatible with Alexa or Assistant. Instead, users give commands to the robot via an included infrared remote control.
Overall, there’s nothing that fascinating about the ILIFE V3s Pro. You can get the same features and much, much more with the Eufy 11S.
