The eufy RoboVac 11S isn't a bad overall robot vacuum, but there's nothing special that stands out about it. It's fairly well-built, the dirt compartment is of a decent size, and it has excellent battery life. Unfortunately, it's difficult to maintain as there are a lot of parts you need to take care of regularly, and there are also a number of parts you need to replace often. Luckily, it comes with an extra set of side brushes and filters, so you won't need to worry about replacing those for a bit. There's no dedicated app, so instead, it comes with a remote with which you can control the vacuum. It can maneuver easily under couches and tables, but because it doesn't have a smart pathing feature, it moves around your room randomly and might miss some spots.

Our Verdict

6.5 Bare Floor

The eufy RoboVac 11S is okay to use on bare floors. It has decent performance on this surface as it easily cleans small debris like rice and it's good with large debris like cereal. Sadly, it's disappointing at cleaning hair. It's also difficult to maintain and there are a lot of recurring costs. On the upside, it has an adequately-sized dirt compartment for a robot vacuum.

Pros
  • Fairly well-built.
  • Sucks up most debris like cereal or rice on bare floors.
Cons
  • Difficult to maintain.
  • A lot of parts you need to replace regularly.
  • Struggles with hair on bare floors.
5.7 Low-Pile Carpet

Disappointing on low-pile carpet. The eufy RoboVac 11S does a great job at vacuuming hair, although it can get stuck around the brushroll. It cleans some large debris like sand, but it loses its performance as the dirt compartment fills, and it's bad with small debris. Unfortunately, it's difficult to maintain and there are a lot of recurring costs.

Pros
  • Fairly well-built.
  • Cleans a good amount of hair on carpet.
Cons
  • Difficult to maintain.
  • A lot of parts you need to replace regularly.
  • Can't clean up much large and small debris on carpet.
6.0 High-Pile Carpet

The eufy RoboVac 11S isn't bad on high-pile carpet. It cleans a good amount of hair, but it struggles with cleaning both small debris, like baking soda, and large debris like sand. It's a fairly well-built vacuum but unfortunately, it's difficult to maintain and you need to regularly replace several parts.

Pros
  • Fairly well-built.
  • Cleans a good amount of hair on carpet.
Cons
  • Difficult to maintain.
  • A lot of parts you need to replace regularly.
  • Can't clean up much large and small debris on carpet.
6.0 Pets

The eufy RoboVac 11S is passable if you have a pet that sheds a lot. It cleans a lot of hair on low-pile and high-pile carpet, but it struggles on bare floors. Hair gets stuck around the brushroll, but luckily it's removable if you need to clean it. It's a fairly well-built vacuum but it's difficult to take care of.

Pros
  • Fairly well-built.
  • Cleans a good amount of hair on carpet.
Cons
  • Difficult to maintain.
  • A lot of parts you need to replace regularly.
  • Struggles with hair on bare floors.
6.0 Stairs

Build Quality

The 11S has a decent build quality and it pretty much has the exact same design as the eufy RoboVac 30C. It's mainly plastic, with a matte finish underneath and a glossy coating on top. The two wheels are rubber and feel durable. The entire vacuum feels sturdy although, like most vacuums, the plastic dirt compartment feels like it could break if dropped. On top, there's an on/off button with a battery indicator light. The power switch for the vacuum is located underneath, and this allows you to completely shut off the vacuum. The robot vacuum is easy to assemble when you first get it as you just need to set up the charging dock and attach the side brushes.

User Maintenance

The 11S is hard to maintain as there a lot of parts that need maintenance, but each part is easy to access.

  • Dirt compartment: The dirt compartment is easy to pull out and you should empty it after each use.
  • Brushroll: It can be taken out by removing the brushroll guard first. You need to clean the brushroll once a week, and the vacuum comes with a cleaning tool.
  • Brushroll guard: Unlike most other vacuums, you also have to clean the brushroll guard once a week with a dry cloth or the cleaning tool.
  • Pre-filter: The pre-filter is inside the dirt compartment and can be pulled out. You can wash it with water.
  • Filters: There are two filters located inside the dirt compartment: a black foam piece and a white high-performance filter. You have to clean them once a week, and the foam filter can be washed with water, while the high-performance filter can't, so you can clean it with another vacuum or the cleaning tool.
  • Side brush: Two side brushes lock into place and are easy to pull off to remove any hair. They need to be cleaned about once a month using a damp cloth with warm water.
  • Wheels: It takes a bit of force to remove and put the wheels back in. You should clean them about once a month with water.
  • Sensors: The sensors on the vacuum should be cleaned once a month with a cloth.
  • Charging pins: You also need to clean the charging contact pins once a month with a dry cloth to remove any dust or debris.

You can clean any part with the brush on the dedicated cleaning tool. If you wash any part with water, they must be air-dried before using them again. If you want a robot vacuum that's easier to maintain, look into the iRobot Roomba 675.

Sadly, there are a lot of parts that you need to regularly replace. You must replace the filters every two months and eufy sells packs of six sets of both the foam filter and the high-performance filter. The side brushes and brushroll guard must be replaced every three to six months, or when they're visibly worn. You must change the brushroll every 6-12 months, and eufy sells these replacement parts through their website or on their Amazon store.

Note that the manual we received with the 11S was Version 1 and didn't include the replacement time for the brushroll guard. The updated manual, Version 2, is available online and includes the replacement time for the brushroll guard.

If you want a robot vacuum with virtually no recurring costs, check out the Samsung POWERbot R7040.

The eufy BoostIQ RoboVac 11S is very easy to store. It lays on the ground and mounts onto the charging dock by itself. You need to make sure wires around the dock are tied with the zip ties that come with it, or else the vacuum sucks them up.

The size of the dirt compartment isn't bad for a robot vacuum. It's the exact same size as the eufy RoboVac 30C. It needs frequent emptying and even though there's no line indicating when it's full, it's fairly easy to see through the plastic.

The RoboVac 11S has excellent battery life. On its most powerful suction setting, 'Max', it lasts just over an hour. On the least powerful mode, 'Standard', it cleans for almost two hours. There's also a battery indicator light on the vacuum. It's blue when the vacuum is on standby, fully charged, or cleaning. When there's minimal battery life left, it turns solid orange and starts to return to the dock, and the battery flashes orange while it's charging. Lastly, the light flashes red when there's an error.

The BoostIQ RoboVac 11S has three power settings: 'Standard Power', 'BoostIQ', which is the default setting and automatically switches between the two other settings depending on the surface, and 'Max'. It also has different cleaning modes, which you can control on the remote.

  • Auto clean: It automatically chooses the cleaning mode and path to optimize its performance.
  • Spot cleaning: The vacuum cleans an area, turning in a spiral pattern for two minutes.
  • Edge cleaning: Near a wall, it reduces its speed to make sure it's cleaned properly, and it can stay in this mode for 20 minutes.
  • Quick clean: The vacuum automatically cleans for 30 minutes and this is the most efficient mode in terms of battery life and performance.

The 11S has decent performance on bare floors. It easily cleans small debris like rice but it struggles with hair as it gets wrapped around the brushroll. With large debris like cereal, the side brushes push some cereal to the side. Even though it sucks up a great amount of large debris when the dirt compartment is empty, it quickly loses performance as the dirt compartment fills.

Disappointing on low-pile carpet, but it's much better than the eufy RoboVac 30C. It sucks up a great amount of hair and a decent amount of large debris like sand, although it loses its performance with large debris as the compartment fills. Sadly, it struggles with small debris like baking soda.

Setting Used "Max"

The 11S is passable on high-pile carpet, especially for a robot vacuum. It sucks up a good amount of hair, although some can get stuck in the brushroll. It's bad with both small and large debris, and once again, it loses its performance as the dirt compartment fills.

This vacuum has just okay maneuverability. The 'Quick Cleaning' mode is efficient at cleaning a small room, but the vacuum loses track of areas it has already cleaned as it doesn't have a smart pathing feature. It's small enough to go underneath couches and tables, but wires are a real challenge for this vacuum. If there's an electric wire laying around, the 11S easily gets stuck, so you have to move the wires on your own or tie them up using the zip ties. It doesn't come with boundary strips, but you can buy some on eufy's store.

The eufy BoostIQ RoboVac 11S has mediocre automation features. It has a remote but there's no option to control the vacuum with a dedicated app. Luckily, you don't need an internet connection to use the robot vacuum. You can adjust the suction power or select different cleaning modes with the remote, and you also schedule cleaning times.

Differences Between Sizes and Variants

We tested the eufy RoboVac 11S, which is only available in black, but there are a few variants, which are listed below. Each variant has a slightly different design and different suction power, so we don't expect our performance results to be valid for the other models.

Model Name Advertised Max Suction Power
RoboVac 11S 1300Pa
RoboVac 11S Plus 1500Pa
RoboVac 11S MAX 2000Pa

If you come across a different variant of the 11S, let us know in the discussions below and we'll update the review.

Compared to other vacuums

As a robot vacuum, the eufy RoboVac 11S doesn't stand out much. It performs much better than the eufy RoboVac 30C, but its performance on bare floors isn't as good as any of the vacuums in the Roborock series, like the Roborock S4 and the Roborock S5. Also see our recommendations for the best robot vacuums, best vacuums, and best robot vacuums for pet hair.

eufy RoboVac 30C

The eufy RoboVac 11S is much better than the eufy RoboVac 30C. Both vacuums have a similar build, they each require the same maintenance needs, and their dirt compartments are the same. However, the 11S performs better overall and it does a much better job cleaning carpets.

iRobot Roomba 675

The iRobot Roomba 675 is a bit better overall than the eufy RoboVac 11S. It's easier to maintain, there are less recurring costs, it's better built, and it has a better battery life. However, the eufy has better performance, especially on carpet, and it's a better choice if you have pets.

iRobot Roomba E5

The iRobot Roomba E5 and the eufy RoboVac 11S are similar vacuums. The iRobot is easier to maintain and there are less recurring costs. It does a better job at vacuuming on both low-pile and high-pile carpet, and its battery takes a much shorter time to charge. On the other hand, the eufy has a bigger dirt compartment and it performs better on bare floors.

iRobot Roomba 960

The iRobot Roomba 960 is better than the eufy RoboVac 11S. The iRobot has a bigger dirt compartment, performs better on any surface type, and it has a smart pathing feature. However, the eufy has a slightly longer battery life, but it takes longer to charge.

Samsung POWERbot R7040

The Samsung POWERbot R7040 is much better than the eufy RoboVac 11S. The Samsung has a smart pathing feature, it cleans better on bare floors, it's easier to maintain, and there are virtually no recurring costs. However, the eufy performs better on high-pile carpet, it has a longer battery life, and the dirt compartment is also bigger.
