The Eufy RoboVac 11 is a robot vacuum designed to make cleaning your floors effortless. With just the click of a button, this vacuum cleaner will crawl your home looking for dirt and debris to clean up. With a few different modes to choose from, the Eufy RoboVac 11 vacuum allows you to specify exactly what type of cleaning you want.

Continue reading below to discover if the Eufy RoboVac 11 is the best robot vacuum for you.


  • Remote allows you to control the vacuum from a distance
  • Several modes for specific cleaning types


  • The Eufy continues working until you send it back to its base
  • Tends to clean slower than other robot vacuums

Bottom Line

  • The Eufy RoboVac 11 is a good option for the user who likes specific cleaning styles when vacuuming.
  • If you’re looking for a robot vacuum with all the bells and whistles, this may not be the best choice for you.


The Eufy RoboVac 11 robot vacuum cleaner offers a sleek, black modern design, much like its competitor the iRobot Roomba series.

The top of the vacuum features a simple auto cleaning on/off button with the brand’s logo in silver letters. There is a large rounded bumper that extends around about half of the robot vacuum. This helps protect itself (and your furniture) while navigating and cleaning your space.

  2. Bumper
  3. Dust bin release (on side)

On the side of the unit is the dust collector release button which allows access to the dust cup and filter.

The underbelly of the Eufy RoboVac has two large rubber wheels which steer and move the robot vacuum while sensors at the front of the unit help it to decipher where to clean. Side brushes sweep debris from sides and edges up into the dust cup.

The Eufy RoboVac 11 uses a single roller brush to help guide dirt, dust, and debris into the dust cup.

This robot vacuum has two contact charging pins which engage with the charging base when the battery is low. With the Eufy RoboVac 11 vacuum, you can either schedule your cleanings or use the remote control for spontaneous sessions.

How it Cleans

The Eufy RoboVac 11 uses integrated infrared light technology to navigate around the space. Eufy’s “Bounce Technology” causes this robot vacuum to drive until it senses an obstacle and then change direction. Drop sensors on the front of the vacuum help to prevent it from driving off staircases or other lofted areas.

There are six different cleaning modes with the RoboVac 11. Depending on the type of cleaning you’re doing, each mode has a different path of cleaning.

  • Auto Cleaning: In this mode, the Eufy RoboVac 11 automatically evaluates the space and determines appropriate cleaning modes for each area. When the area is clean or when the battery becomes low, this robot vacuum will automatically return to the charging base.
  • Spot Cleaning: In this mode, the Eufy robot vacuum cleans a particular area in a spiral pattern. This is mainly used where there is a concentrated area of dirt or debris.
  • Single Room Cleaning: In this mode, the RoboVac 11 will only clean one room and then stop.
  • Edge Cleaning: In this mode, the robot vacuum will follow the walls and travel along the edges of a room, avoiding the middle of the room.
  • Manual Cleaning: In manual clean, the user has the power of direction. Using the remote control, you can drive the robot vacuum cleaner forward, back or side to side to clean a very specific area.
  • Max Cleaning: While I don’t really think this counts as a separate cleaning mode, Eufy does offer a “Max Clean” option which uses the higher possible suction that is required for vacuuming carpets.

During any of these cleaning modes, the Eufy RoboVac 11 robot vacuum uses three cleaning tools – an underbelly spinning brush, roller brush and suction power to collect debris. There are two filters in this vacuum, one HEPA filter and a washable foam filter.


All of the separate cleaning modes can be accessed with the remote control or you can simply press the auto clean button and let it get to work.

Size & Dimensions

This Eufy robot vacuum sits at 3.1″ tall and has a total width of 13″. Like many other robot vacuums, the smaller stature allows it to drive underneath furniture and other low spaces.

One of the most common issues with many different types of robot vacuums is simply getting stuck- or rather, getting slightly stuck.

This can happen if the robot attempts to squeeze under or in-between tight spaces, which can result in cosmetic scratches on the vacuum.

As a result, I would recommend keeping an eye on the Eufy (or any robot for that matter) the first few cleaning sessions to see if it has problems with any areas in your home.

The Eufy RoboVac 11 is definitely on the lighter side at only 6.7 pounds. This can be advantageous compared to heavier robot vacuums, as the relative weight difference should make it less likely to be potentially knock furniture and other objects over in your home. Despite the lighter weight, it still has a solid and durable feel to it.

Accessories & Parts

The Eufy RoboVac 11 robot vacuum includes the following accessories and parts:

  • Four spinning brushes
  • Two HEPA filters
  • Remote
  • Charging base and cord
  • Cleaning tool

Cleaning Tests

The following vacuum cleaner tests are designed to show how the Eufy RoboVac 11 performs on different surfaces, picking up a variety of debris types. We test on three different floor types, including hardwood floors, low pile carpet, and high pile carpet. For each floor type, we test the vacuum cleaner against:

  • Rice – 3 ounces
  • Dry Cereal – 1 ounce
  • Kitty Litter – 3 ounces
  • Sugar – 3 ounces

The base surface of our testing lane is an engineered hardwood floor. For our carpet tests we slide in a low pile and high pile carpet insert on top of the hardwood floor.

Testing Debris – From left to right: Rice (3 oz.), Kitty Litter (3 oz), Cereal (1 oz), Sugar (3 oz)

Our vacuum cleaning process strives to be as consistent, fair, and true to real world use as possible. Our tests utilize the following procedure:

  1. Measure the weight of the testing debris and the weight of the empty vacuum debris container.
  2. Spread the respective debris type evenly across the central portion of the testing lane.
  3. Run the vacuum cleaner over the testing lane.
  4. Measure the weight of the now filled container and take notes on the cleaning performance.

Hardwood Floor

As the first test surface the Eufy vacuum went up against, it seemed to work a bit slow. That said, it was able to clean up almost every ounce of debris that we spread out across our testing lane. While time may not have been the best attribute on hardwood floors, the Eufy RoboVac 11 certainly performed well with regard to how much dirt / debris it was able to pick up.

Low Pile Carpet

The low pile carpet test was a bit better when it came to time, but the Eufy RoboVac vacuum did struggle a bit with some of the debris types. Cereal and rice were both cleaned up with ease. However, kitty litter and sugar gave this Eufy robot vacuum a little more trouble. While the vacuum was able to suck up a majority of the mess, the remaining debris seemed to be a result of lower suction power.

While watching the Eufy 11 on the sugar portion of our low pile carpet test, I was able to spot the sugar quite clearly after the vacuum had already made a few passes down the lane. In comparison, the iRobot Roomba 690, had strong enough suction to lift more of the sugar and suck it up.

High Pile Carpet

After completing the high pile carpet tests on the Eufy RoboVac 11 vacuum, I saw results similar to that of the low pile carpet. It seemed as if the kitty litter and sugar had sank too deep into the carpet and this Eufy vacuum did not have strong enough suction to clean it up. Therefore, the results for both kitty litter and sugar were both slightly worse than the low pile carpet.

Setting up the Eufy 11 robot vacuum is quite simple. Remove all of the parts and accessories from the box, pop two of the four brushes into their respective slots (the other brushes are for replacement), place the vacuum on its charging base to charge, then let it go. There are no tools required, as this vacuum comes entirely built with the exception of sliding the two spinning brushes into their appropriate notches.

Using this Eufy robot vacuum is just as easy as setting it up. Press the power button on the actual face of the unit or use the remote included with the vacuum. Either will allow you to vacuum your floors with very little effort on your end.

The interface on the top of this Eufy vacuum is also easy to understand, as the power button is the only button. That said, you have to be sure that the vacuum is actually turned on by the smaller power switch on the side of the Eufy, then pressing the top button will put the Eufy RoboVac 11 into action.


Maneuvering the Eufy RoboVac 11 is as easy as it gets. Turn it on and you’re good to go. In fact, you even have the option of controlling this robot vacuum with a remote, which is included with the purchase of the vacuum. There is no pushing this unit around, as it is designed to automatically drive around your home and do all the hard work for you.

Built with a circular design, this vacuum cleaner is able to rotate in a 360° degree manner. This allows the vacuum to wrap around extremely tight turns, cleaning areas most vacuums would need a few passes to get.

With this circular construction, cleaning corners can be a bit more difficult. That said, the Eufy RoboVac vacuum contains two spinning brushes attached to the bottom of the vacuum, which adds a little reach to the unit. Therefore, these brushes are able to reach into the corners, fling the dirt or debris out of the corner, and go clean it up. To that end, these brushes may also fling debris back into those corners, so there could be times where this robot vacuum cleaner is having to work twice as hard to get one mess.

  • Weight: 6.7 pounds
  • Width: 13″
  • Height: 3.1″
  • Turning: 360°


The following table indicates the frequency at which you will likely want to replace the various parts and components of the vacuum. The following replacement frequencies are what the manufacturer recommends. However, your individual experiences may vary.

Accessory / PartReplacement Frequency*Replacement Cost
Filter set (HEPA & Foam)4 monthsCheck Price
Side brush6 monthsCheck Price
Rolling brush12-24 monthsCheck Price

Maintaining the Eufy 11 vacuum is relatively simple. Empty the filter, clear the brushes and rollers of any tangles, and replace parts when necessary.

As a smaller unit, compared to larger upright (like the Shark Rotator), the Eufy RoboVac 11 does not have many parts that need tending to. Keeping the brushes spinning and the filter / dust bin empty will allow for optimal cleaning performance.

Monetarily speaking the Eufy does not cost a whole lot to take care of. Noted in the table above, this vacuum should cost around $22 a year to maintain.

*Unfortunately, we were unable to find the manufacturer’s specific recommendations for the replacement frequency of the various parts on the RoboVac. As a result, the replacement frequencies indicated in the table above are estimations based on other common recommendations for robot vacuum replacement frequencies.


All vacuum cleaner reviews on Modern Castle are put through our standard noise test. For this test, we use a sound meter to measure noise in terms of decibel level approximately 3 feet away from the vacuum.

At 3 feet away, the Eufy RoboVac 11 robot vacuum emits 56 dB of sound.


The Eufy RoboVac 11 uses a Lithium-Ion battery to power the unit. According to Eufy, new battery will last for 3 years when RoboVac is left in stand-by mode. To preserve the lifespan of the internal battery, be sure to use RoboVac at least once every 3 months.

In addition to the internal Lithium-Ion battery, the remote control also requires 2 AAA batteries.

Charging Time5-6 hours

Replacement Cost

Perhaps my biggest concern with the Robovac 11 is simply how difficult it is to get a replacement battery. We searched several sites around the internet, including and, which does not appear appear to have Eufy Robovac replacement batteries for sale.

I thought this was odd, so I reached out to Eufy’s chat support directly who told me the following:

“To purchase an extra battery for [the Robotvac 11], please make a payment of 15USD (including the battery and the shipping cost) to [email protected] PayPal.”

I must admit, I was shocked that this is Eufy’s system for getting replacement batteries to their customers. I personally would not want to go through the trouble of emailing customer service and sending direct PayPal payments just to get a replacement battery.

Run Time

Eufy RoboVac 11 can run for up to 100 minutes and takes 5-6 hours for a full charge.

Priced moderately, the Eufy RoboVac 11 offers a good value. There are some ups and downs with the cleaning performance, but for the price you pay, this is a well-rounded vacuum cleaner.

Compared to other robot vacuums we have tested thus far, the Eufy is one of the lower cost options. That said, the lower price point does somewhat reflect the overall performance. 

By no means is it bad, in fact, I would classify it as well above average, but slightly more expensive options, such as the Roomba 690 robot vacuum, are equipped with wifi and performed better in our cleaning performance tests compared to the Robovac 11.

Eufy does offer a 1 year warranty with their vacuum and a 30 day return period is offered through Amazon. Within Eufy’s warranty, they state the following:

Eufy will replace a defective product with a brand new product if the replacement request is made within six months of purchase; if the replacement request is made after six months of purchase, Eufy will replace the defective product with a factory refurbished model of equal value.

For the most part the Eufy warranty is similar to other robot vacuums. However, I will say that I don’t love their replacement in months 7-12 with a refurbished model. In cases where my robot vacuum had completely died I would not be terribly excited to receive a refurbished unit.

Who Should Buy the Eufy RoboVac 11 robot vacuum?

The Eufy RoboVac 11 is a robot vacuum built to clean your house with just once click of a button.

The Eufy is sold at a lower cost, creating a more affordable robot vacuum for the everyday user. If you’re someone who needs constant vacuuming around the house, the Eufy may be a good option to explore.

I would recommend the Eufy RoboVac 11 if you’re looking for the following features in a robot vacuum.

  • Like the idea of a robot vacuum – Robot vacuums are designed to create a labor free environment when it comes to vacuuming your home. This Eufy robot vacuum will automatically drive itself around your home and clean up messes without you having to lift a finger.
  • Want a remote to control the vacuum – The Eufy Robovac 11 comes with a remote, allowing you to control the vacuum from a different room, or even right in front of it. Whether you want to set it to go do a specific clean, a spontaneous clean, or just need it to pick up a quick debris field, the remote gives you that option.
  • Don’t need the extra bell and whistles – Although the Eufy is a robot vacuum, it does not include many bells and whistles. Compared to some of the other robot vacuums we have tested, this vacuum does not include wifi or a memory feature. Therefore, it will have to drive around your home and search for dirt and debris instead of mapping out exactly where it should clean every time. This can lead to a slightly slower cleaning session, as compared to more advanced robot vacuums.
  • You’re okay with extra hassles to get a replacement battery – as of the writing of this review you cannot simply purchase a replacement battery by going to Eufy’s website. Instead, you must contact their customer support and make a PayPal payment to (the company that I assume manufacture’s their batteries) in order to get a new battery if your original battery dies outside of the warranty.
