Product Overviews

Eufy 11S

The Eufy Boostiq Robovac 11S was widely regarded as the best robot vacuum cleaner in 2019 and still performs very well. It is an update on a previous model that has been re-engineered to a slimmer figure and has a quieter mode of operation. 

The Eufy 11S has a suction power of 1300Pa with an average speed of 10.5 in/s. The BoostIQ Technology also enables the suction power to be increased automatically on detecting carpet and harder to vacuum surfaces.

By adjusting the suction power automatically, it means the battery is used more efficiently for longer cleaning periods. One charge can go for up to 100 mins.

While I’m talking about the battery, it’s worth knowing that the vacuum will return to base when the battery is low. However, as it uses sensors, rather than smart mapping, if the base is not in a clear and obvious position, it can struggle to find it.

It has a few other important external features such as infrared sensors for evading obstacles, drop-sensing technology, automatic rechargeability, and a glass-top cover for protection. 

Despite its slim profile, it has large wheels that help it to roll over door ledges and other obstacles in order to move more freely and cover a wider range of motion.

A couple of nice features that are missing from this vacuum are a HEPA filter and WiFi connectivity. 

Other features include a remote control with 2AAA batteries, an AC adapter, high performance tools, side brushes, 5 cable ties and an accessible chargeable base. The Eufy 11S also has a 12-month warranty.

Eufy 30C

Much of the features in the Eufy Robovac 30C, such as the slim profile and Boost IQ Technology and multiple sensors are the same as the Eufy 11S.

One of the stand out features of the Eufy 30C is the fact it has WiFi. You are able to control the robotic vacuum via the Eufy Home app, Amazon’s Alexa, and the Google Assistant.

The Eufy 30C comes with some boundary strips so you can block off certain areas of your home that you do not want to be cleaned. These are great for stopping the vacuum running into pet food bowls or kids’ toys that could get tangled in the brushes.

The Eufy 30C also comes packaged with an extra set of high-performance filters, remote control with 2 AAA batteries, an AC power adapter, a charging base, a cleaning tool, spare side brushes, and a 12-month warranty.

The Eufy 11S vs 30C: The comparison

So now you know a little more about each model, let’s highlight some of the important aspects you should consider before making your purchase.


In terms of runtime, both the Eufy 11S and 30C have the same operation duration which is 100 minutes. They also have the same charging time of 300 minutes and will try their best to automatically dock when low on battery.

Neither of these models will be able to automatically resume after charging or remember where they were when they stopped.

Size of cleaning area

The 11S and the 30C have the same cleaning area range. They both cover floor areas of 1292 ft per every 120 meters square. Their cleaning modes also affect the range of operation.

Cleaning functionality

Neither of these robotic vacuums use smart mapping, they rely on bump and go. However, there are a few different cleaning modes available. Both the 11S and the 30S have auto-clean, spot cleaning, edge mode, and single room cleaning features.

On the belly of the robot, both models use a 3 point cleaning system that will loosen dirt before sucking it up into the large dustbin.

App control

The Eufy 30C supports 2.4GHz WiFi and works with the Eufy mobile app as well as voice controls. This means that you can track the progress of the vacuum, see live updates and also use the “Find Me” that enables the owner to be able to track it down in the occasion that is hidden in a corner or underneath something.

It’s also nice that you can set it cleaning from anywhere in the world. There aren’t many time you will want to do this, but it is fun to tell your parents you just need to vacuum your house while visiting them for dinner,

The Eufy 11S has no WiFi connection.


Both of these vacuums have this feature available. However, it is much easier to set up on the Eufy 30C due to the app connectivity. Setting timing on the Eufy 11S can only be set on a 24 hour basis and can be fiddly to do as there is no screen, you have to rely on counting beeps.


The 30C has a stronger suction power of 1500 Pa when compared to that of the 11S which has a suction power of 1300 Pa. This ensures good performance on bare floors and medium pile carpets. Both have intelligence features that enable them to increase these respective suction powers when it is required.

Boundary Strips

The Eufy 30C is able to detect magnetic boundary strips which enable you to mark off areas of your house while cleaning. I have used them in the past to mark off my toddlers’ room as I couldn’t face picking up all those toys before vacuuming. It’s also good to mark pet-friendly areas, where the food or water bowls are.

The Eufy 11S does not have this feature.


The Eufy 11S has a high-efficiency triple filter whereas the Eufy 30C contains a HEPA filter for better performance.

Size and structure 

Both models have a sleek thin design. They are just 2.65 inches in thickness and they weigh around the range of 5.75lbs. Amazingly they both still manage to fit a 600ml dustbin, up there with some of the largest on the market.

They share the similarity of a primary V-shaped brush roll and two side brushes. While they both lack a resume function, they can both recharge automatically and have the same battery life of 2600mAh.

In both vacuums, there are laser sensors for localization, drop detection sensors and obstacle detection sensors. 


While price ranges may differ according to where you buy, the 11S is generally cheaper with an estimated average of about $200

As you would expect, with the upgraded features, the 30C model is more expensive, usually found between $60 – $80 more than the Eufy 11S.

Who are these Eufy robotic vacuums for?

Both of the Eufy 11S and 30C are at the budget end of robotic vacuum cleaners meaning they are missing a few nice features, but both offer excellent value.

I would recommend these models for people who may have never owned a robot vacuum before and are wondering if they would find one useful.

I’d also add that due to the lack of smart mapping and intelligent features such as restarting from the same place it stopped previously, this is better suited to smaller homes. 

Finally, while they do an OK job on medium pile carpet, they are better suited to hard floors and low-pile carpet.

So which is better? The Eufy 11S vs 30C

These machines do all of the basics pretty much the same. They have the same great design, cleaning performance, large dustbin, runtime and return to charge.

In my opinion, there are really only two stand out differences, the WiFi connectivity, and the ability to use boundary strips. To be honest, while they are nice to haven neither has a huge impact on the actual cleaning performance of the robotic vacuum.

However, one huge benefit of the 30C Eufy robot vacuum is the much easier scheduling. I have my vacuum scheduled to run at 3am every night. While this is possible on the 11S, it is a bit finickity to set up.

Based on the fact that you will be using the vacuum for a couple of years at least, I really don’t see that $80 is too much to pay to include the extra features and upgraded filter, so overall I would recommend the Eufy 30C.

However, that is not to say I am not recommending the Eufy 11S. Both of these are extremely well made and popular robotic vacuums that deliver outstanding value for money.

Any other recommendations?

We do have a couple more articles about robots in this price range. I’d recommend reading. Be sure to check our post comparing the Eufy 11s vs 11s MAX and we also compare the Eufy 30C to the 35C.


  1. How often do you have to empty the Eufy 11s or 30c?

    Both vacuums have a generous 600ml dustbin, it can easily go 3 to 4 cleanings without emptying. However, for best performance, it’s good to get into the habit of emptying the bin and checking the brushes are not tangled once a day. It only takes a minute.

  2. How long does it take for it to get a full charge?

    Around 3 to 4 hours from empty.

  3. How do they cope with pet hair?

    Very well. For dogs and cats, neither the 11S nor the 30C will have problems picking up the hair. I would slightly favor the 30C for pets due to the inclusion of the HEPA filter that will help with odors and boundary strips so you can block off litter boxes and feeding areas.

  4. Where can I buy Replacement brushes?

    You can find a wide range of replacement parts on Amazon. Including brushes.

  5. Will they fall down stairs

    No, both have onboard anti-drop sensors that will prevent this.

  6. Will these robot vacuums clean under chairs and tables?

    Yes. At just 2.65 inches, these are two of the slimmest robotic vacuums on the market so will get under lots of furniture.

  7. The Eufy 30C has WiFi, does this mean the robotic vacuum must be connected to the internet to work? 

    No, it does not. There is an on-off button on the unit and remote control. I have actually found the remote control more convenient to use than the app for everything apart from scheduling.
