If you’re too excited and want to know the winner, it’s the eufy Robovac 25c. Continue reading below for the details of why I picked the 25c as the better vacuum.


Size Dimensions

The Robovac 11s has a small, compact build similar to that of the Robovac 25c. They both possess a diameter of 12.8 inches and height of 2.8 inches.

This small size is particularly helpful in getting under low furniture but could also become a problem when it comes to climbing carpets or rugs.

Eufy previously experimented with varying sizes early on and soon stuck with the smaller size for subsequent designs.

Battery and Charging Capacity

Eufy ensured they spared no cost in the battery design of both the Robovac 11s and the Robovac 25c. Eufy equipped the 11s and 25c with the Lithium-ion battery that has a capacity of 2600 mAh. That implies you get a lot of run time from your vacuum robot, which is approximately 100 minutes of vacuuming before it gets low and you need to recharge.

Charging from a low charge to 100% takes about 5-6 hours and Eufy recommends you charge your Robovac fully before using it.

What Kind of Filter Do They Use?

The 11s and 25c are both equipped with high-performance filters and a foam filter. With this combination of filters, Eufy designed two robots that can trap smaller dirt particles like dust that would otherwise escape when using other products.

Eufy also includes another filter that traps larger dirt, it functions to protect the high-performance filter and the foam filter from dirt that could clog it.

Yes, that’s three filters altogether.

Types of Brushes, Suction Power and Cleaning System

The brushes of both the 11s and the 25c are similar. Both robots come equipped with 2 side brushes, one on each side that moves by counter-rotating and sweeping up dirt and dust.

They also have a brush underneath that digs into tough rugs and carpets to remove deep-rooted dirt. To complete the triple brush system, they are also equipped with roller brushes that also help in sweeping different kinds of surfaces.

The difference between the two vacuum robots is in the suction power. While the 11s has a suction power of 1300Pa at maximum level, Eufy went a step further with the 25c giving it a suction power of 1500Pa at max level.

That means the 25c can increase its suction power when it needs to, making it more suitable to clean tough carpets and rugs.

Navigation and Mapping Technology

Eufy equips both the 11s and 25c with Infrared sensor technology that enables navigating their way around the room without bumping into obstacles or falling downstairs.

The movement for the 11s and 25c is random, so there is no specific planned path to clean. The robots move randomly and still find a way to clean every inch of the room.

The Robovac 11s and the 25c move easily from one surface to another without wobbling or turning over because of its smaller size and low center of gravity.

Controlling the Robot Vacuums

The Robovac 11s has a power button at the top of the robot and a remote to control its movement and functionality. It doesn’t support voice commands nor the EufyHome app.

With the Robovac 25c, it has several alternative methods of control. With the backlit controls on the top of the vacuum, you can start and end cleaning too.

The new WiFi technology Eufy added enables you to control the robot from your phone once you install and connect to the EufyHome app. There’s also a function to control where you want it to go as well, like a remote control car.

The 25c is also compatible with Alexa, Amazon’s digital assistant, giving you voice control ability. This means you can control your vacuuming without even being in the same room.

Maintenance of the Robots

Eufy recommends certain cleaning and maintenance measures that promote the shelf life of both the 11s and 25c. These measures include periodic cleaning and maintenance of the detachable parts that make up the robot and emptying the dust collector after each vacuuming session.

These detachable parts include; the side brushes which should be inspected for deformity in the shape or for damage and should be replaced accordingly. Underneath the vacuum robot is another brush design that is used for much deeper cleaning of tough rugs and carpets.

The roller brushes should also be inspected for anything that could hinder its movement. The entire robot is cleaned with a dry napkin or dust vacuum. You’ll want to clean them to avoid the accumulation of dust. This is true for any robot vacuum too.
