House maintenance takes up much needed time that just isn’t available anymore, and to offset this balance robot vacuums.

What’s the Difference between 11s vs 30c?

Running Duration and Battery Life

Eufy knows that these features are imperative to the pull of their consumers. They utilize a lithium-ion battery with a battery capacity of 2600 mah equipped with 14.4V and 24W suction power. The two models here, both have a running time of 100 minutes. This is after having a charging time of 300 minutes.

In cheaper robot vacuum cleaner brands, it usually takes quicker than that, but this is because those batteries are much smaller than the ones that Eufy employs. When the vacuum cleaner hits a low battery level, it’ll automatically set a course back home to its charging station.

Ideally, it will complete the journey and begin to charge for the next excursion, but if it gets lost and dies somewhere in your home then you will have to manually return it to its dock.

It’s an important aspect to think about, and given that both these models have the same advantages and disadvantages when it comes to battery life and their running duration, we’ll have to remain neutral.

Verdict: Eufy Robovac 11S and 30C

Cleaning Area Range and Quality

The next feature that’s on our minds, is how big is the area these vacuums can clean and how well can it do it? These Eufy models can each cover up to 1292 ft per 120 meters squared, which isn’t bad if you live in an apartment or smaller house.

Let it be noted that these vacuums don’t employ smart mapping and have a bump n’ go system. This means, depending on any items are in this area, could mean your vacuum cleaner is getting stuck or lost.

The quality of the cleaning can differ from these cleaning modes given the different filters and added features. Let’s explore where they remain similar. Both vacuums use 4 different cleaning modes that are as follows:

  • Auto-clean
  • Spot cleaning
  • Edge mode
  • Single room cleaning features

They also encompass a 3 point cleaning system and the utilization of different filters. The filters include a high-performance filter, a pre-filter, and a foam filter.

They collect and trap tiny particles ensuring that no debris is left behind. It means, wherever the little vacuum roams you can believe that it’s picking up the maximum amount of dirt. The side brushes on the bottom will continually rotate, swinging, and sweeping in any dirt and is perfect for room cleaning.

There are 2 on each side, gathering up larger particles of dirt and sending it to the rollers in the middle. The sturdy side brushes are made of bristle and rubber for those stubborn fuzz balls in your medium pile carpets. The Robovac 11s and 30c have a similar brush design consisting of 2 side brushes and both are great on hardwood floors with their side brushes.

The biggest and most notable difference between these models’ cleaning ability is one’s knack and adaptability to different terrain. The robovac 30C is perfect for low-build carpet and hardwood floors, whereas the boostIQ Robovac 11S is less adaptable especially for pile carpets.

If your living space encompasses more than just hard floors, then you might have to consider getting the Robovac 30C. Even though the boostIQ Robovac 11S is the more affordable option, there would be no point in investing in it if you can’t be 100% sure that it could clean your bare floors effectively and is perfect for cleaning your pet hair, if you own one.

We may be looking for convenience, but reliability should come undisputed with prices like these. This is why we have to go with Eufy 30c. Yes, they share many of the same qualities, but at least with the 30C we can trust that the job is getting done, no matter the terrain.

Verdict: Eufy Robovac 30C

Size, Structure, and Suction Power

We are talking sleek and slim when regarding the design of these two robot vacuums. They’re built to work in the background of your life and remain as unseen and unheard as possible. Eufy believed that smaller is better by compacting the size of their vacuum cleaner as they update their models.

The 30C Eufy Vacuum is the newer Eufy robot vacuum cleaner and has a height of 12.8 inches and a width of 2.8 inches. The boostIQ Robovac 11S is just a bit bigger, but depending on the cluttered state of your home, size just might not be an issue. We prefer the more compact design because it’ll have a better ability to reach those tucked away places.

As for the shape of the undercarriage, it is primarily in a V-shaped roll that is meant to collect the debris and sweep it to the back of the vacuum. The difference will lie in each model’s suction power when it comes to picking up particles.

The boostIQ Robovac 11S has a suction power of 1300 Pa which pales in comparison to the 30C’s 1500 Pa. It seems Eufy was able to compact their design without sacrificing any of it’s cleaning prowess. In fact, it’s even stronger than their bulkier design, showing that technology has made so many things possible.

For this reason, we have to go with Eufy 30C. There are many similarities, but the parts where the 30C excel is in features that really matter. There may be some bells and whistles, but the functionality is there.

Verdict: Eufy 30C


To reiterate a previous claim, the Eufy robot vacuums use a sensor technology that involves bump n’ go. There is not mapping technology installed in the robots that will allow them to recognize their surroundings.

This also means you won’t be able to map out a path for them or expect them to clean specific parts of your house. The cleaning will essentially be random. This doesn’t mean that their cleaning is any less effective. In fact, they both thoroughly clean well.

The only downside to this factor is that they can get lost or stuck if there are cluttered parts in your home. The Eufy 30C comes with an app that we’ll get into more detail later, but it utilizes a Find Me feature allowing you to keep tabs on your robot vacuum cleaners whenever you want.

Due to this feature, we are inclined to go with the Eufy 30C, even though the Eufy 11S has many similarities to the newer model. If an app is something you can live without, then by all means the Eufy 11S will get the job done.

We find the 30C more preferable in regards to the added features because it comes with so much more for only a slightly higher price. With everything that the 30C comes with, it continues to make us believe that we are getting the biggest bang for our buck! The boundary strips create “no clean zones.” Placing boundary strips down on the ground create boundary walls around objects or places you don’t want the 30c to clean.

Verdict: Eufy 30C

Controlling the Robots

This might be the feature that sways you from the boostIQ Robovac 11S for good because it certainly swayed us. Since the 11S is an older model it forgoes features like voice command and remote control. There is no WiFi technology associated with this model, which is why the 30C automatically wins here in our book.

The Eufy 11S is a more affordable option, but for only 50 dollars more, you receive the 30C complete with an accompanying app and WiFi features. Let’s go into more detail about what this means for the 30C. Eufy 30c comes with boundary strips technology as well.

The eufyHome app is free to download and install. From your phone, you’ll be able to do a variety of things such as stop, start, schedule, and more! Within an instant, your smartphone has also become your vacuum’s controller.

It’s able to bring something more to your vacuuming experience while remaining reliable and convenient. There is also a Find Me feature, that helps you track down where your vacuum is in case it doesn’t survive the journey to the charging dock.

This is a really helpful feature, considering this is bound to happen occasionally. Better to quickly track it down, rather than spending time checking every nook and cranny of your home to make sure it gets fully charged.

Though the Eufy 11S doesn’t have the range of remote control that the 30C offers, it still provides scheduling. If you care to, you can schedule a set time with the Eufy 11S, but this involves a tedious process of listening to beeps that signify the time of day because the Eufy 11S doesn’t come with a screen. Scheduling with the 30S is made much easier with the app, and the WiFi connection helps accomplish it with remote control.

To elaborate, the 11s and 30C can connect to the WiFi network of your home and because of this, you can control the robot vacuum wherever you are. This is more of a cool factor rather than a necessity.

It’s perfect for hypothetical situations where you’re about to have company over, but you’re at work and the floor could use a quick clean. The only downgrade that comes with a WiFi-connected robot, is that it will rely heavily on your network to function.

This may not seem like a huge problem, because chances are if you’re thinking about buying one of these you hopefully have a network that is better than 2G. If you have Alexa or Google Home, then we have good news for you.

With the 30C’s ability to connect to your WiFi connection, you are also able to connect with your home command system. This means you can have a voice command with your robot vacuum. Imagine the possibilities of utter convenience with an ability like this.

Another cool feature that may not read as a necessity, but given the slim price difference with the boostIQ Robovac 11S it definitely feels like an added perk. Once again, the 30C proves to be a superior robot vacuum and with everything it has to offer in this aspect, it becomes the winner.

Verdict: Eufy 30C


When looking for a robot vacuum, you can’t really go wrong with the Eufy brand. They have durable, well-built vacuums that fulfill the basic promises they set out to make. The whole point of a robot vacuum is to have something that conveniently cleans your home.

Anything more than that is extra, and depending on the cost either a flop or a steal. The 30C has proved to be a great product that accomplishes an effective clean and much more. With the WiFi connection and accompanying app, it really pushes the boundaries of what you can do with a vacuum.

Along with the other features the 30C seems to offer, especially when it comes to adaptability, it feels like a clear purchase to make. You’ve made it this far and done this much research, and it feels like there just couldn’t be a clear winner.

Yet, we do recognize that the boostIQ Robovac 11S still offers a similar clean that the 30C does, whilst being 50 dollars cheaper.
