Today, we’re taking a look at five Eufy robot vacuums. These vacuums are the Eufy 11S, the Eufy RoboVac 12, the Eufy RoboVac 15C, the Eufy RoboVac 30C, and the Eufy RoboVac 35C.

You’re going to learn all about the unique features and attributes of these robot vacuums. And, by the end of this article, you will know which one of these robot vacuums is the right one for you!

Eufy 30C

Now, let’s start with the Eufy 11S.

Eufy RoboVac 11S

Out of all of the vacuums on this list, this is the most affordable, but it is also the “weakest”, and it contains the least amount of features.

With the Eufy 11S, you have access to a total of 1300Pa, when it comes to the overall suction power. This is a decent amount of suction, and it will work great on hard flooring, but it won’t work as well on softer flooring, such as carpets or rugs. Especially not on thick ones. This is because dirt, dust, and debris tend to get lodged into those types of surfaces, and the suction isn’t always powerful enough to vacuum all of that stuff up.

During the cleaning process, there is a feature known as “Boost IQ” that is activated automatically. Boost IQ is a simple feature, that is also very effective, and very convenient.

Whenever the Eufy 11S goes from one surface, to another surface that requires greater suction power and speed, it automatically changes the suction speed, based on the information that the sensors are feeding the vacuum. You don’t have to adjust the speeds, or the other settings manually, and this makes things especially convenient. On top of that, when the vacuum goes to another surface that doesn’t require that amount of suction power, it will revert back to the normal speed, which will save battery life.

The cleaning process is done using a “3-Point Cleaning System”, that consists of the main brush roll, which is located on the front of the vacuum. This is the biggest brush, and also the most effective brush, and it’s used to gather up most of the dirt, dust, and debris. On the back of the vacuum, there are two other, much smaller, brushes, on both sides. These also help to gather up the dirt, dust, and debris, and then to push it into the suction pathway.

Everything flows through a filtration system that consists of a single dual-layer filter, and a third filter that consists of only a single-layer. The dual-layer filter is designed to break up and filter out all of the larger particles, and then the single layer filter breaks down all of the smaller particles, such as allergens.

Finally, at the end of the cleaning process, everything goes into a 0.6-liter dust box. For a robot vacuum, this is a fairly large dust box, which is very convenient, since it means you won’t have to constantly empty out the dust box, while the vacuum is cleaning.

You can run the robot vacuum for a total of 100 minutes, before you need to recharge it.

Ultimately, the Eufy 11S is a great robot vacuum, if you want something simple, easy-to-use, and affordable. It’s not very powerful, but it works well, and you won’t have any issues.

Eufy RoboVac 12

The Eufy RoboVac 12 improves certain aspects of the Eufy RoboVac 11, but other than those small improvements, it is a very similar robot vacuum.

Instead of having access to only 1300Pa of suction, the Eufy RoboVac 12 gives you access to 1500Pa of suction. Now, there isn’t a huge difference between 1300Pa of suction, and 1500Pa of suction. However, the difference is notable enough, because it makes it a lot easier for you to clean carpeting and rugs.

With only 1300Pa of suction, you can still clean those things, and you can still clean them well, but some of the material that is stuck within the carpet will be a lot harder to vacuum. With the 1500Pa of suction, it makes that process a lot easier.

Other than that, there are no differences. Even the price is quite similar. So, if you want some extra power, you don’t need to spend much more to have that.

Eufy RoboVac 15C

Unlike the Eufy RoboVac 12, the Eufy RoboVac 15C only offers 1300Pa of suction power. This is a downgrade in comparison, and so if you want something that is especially powerful, you’re probably not going to want to purchase the Eufy RoboVac 15C.

However, the Eufy 15C does offer some other features that are very useful and important.

Unlike the previous RoboVac models we’ve looked at, the 15C has smartphone functionality, and it also works with Amazon Echo.

Instead of having to rely entirely on a remote control that has access to all of the main features of the vacuum, you can install the special app that Eufy has developed. Using this app, you can create a custom schedule for the vacuum, turn the vacuum on – even when you’re at work or far away from the vacuum – change the cleaning mode – there are four, including “Spot Cleaning” and “Automatic Cleaning” – tell the vacuum to recharge, or use the “Find My Robot” feature. The “Find My Robot” feature tells the robot vacuum to emit a sound, and this sound will enable you to find the 15C, if you have lost it.

Using Amazon Echo, you can say certain voice commands aloud, and these commands are then sent to the 15C, and it will do what you tell it to do, such as turning on, or turning off.

Other than the differences mentioned, the Eufy RoboVac 15C is pretty much the same exact vacuum as the other ones. But, the price isn’t too different from the other models, which means you can have access to this extra convenience for only a little bit more money.

Eufy RoboVac 30C

One of the more recent vacuums developed by Eufy, the Eufy RoboVac 30C is quite similar to the previous models, but it is a more efficient robot vacuum than any of the previous ones.

In terms of the suction power, you have access to 1500Pa of suction power. This is a really nice amount of power, and it makes cleaning most floors and surfaces an easy process. Even if you are cleaning carpets and rugs, and even if they are thick, you’ll still be able to clean them very well. Not as well as you’d be able to clean them with an upright vacuum, but the cleaning process will still go smoothly.

You also have access to the same smartphone functionality, which is incredibly convenient. Using Amazon Echo is also an option, as is using Google Home. Both of these Smart Home devices are compatible with the Eufy RoboVac 30C, and they work very well, you won’t encounter any issues or problems with these devices, and using them with the 30C.

However, the main feature that Eufy has added is the inclusion of these things called “Boundary Strips”. Boundary Strips are unique devices that you lay down on the floor, and they create a barrier that defines the boundaries of where the robot vacuum can, and cannot, go. They emit a signal that tells the vacuum not to cross them.

The biggest benefit of this is the fact that it makes it much easier to have the vacuum clean one particular area extra thoroughly, rather than the vacuum running around, seemingly at random. If you want to clean your bedroom, for example, and there is no door, you can put the boundary strips in the frame of where the door would be, and the 30C will clean for as long as you want, ensuring your bedroom is extra clean.

Eufy RoboVac 35C

The Eufy RoboVac 35C is Eufy’s newest robot vacuum. It came out only recently, and while it isn’t too different from the other Eufy robot vacuums we’ve looked at, it does improve on some things, and is, overall, a great robot vacuum.

With 1500Pa suction, you can clean just about any type of surface/floor using the Eufy RoboVac 35C. It doesn’t matter if you have soft floors, or hard floors. This is a very versatile robot vacuum.

Once again, you also have boundary strips. These boundary strips are 6.6 feet long, and so you can lay them out within many spaces, making it easy to designate specific areas to clean.

Other than that, this is a very similar vacuum, in comparison to the 35C.
