Size Dimensions

In designing products like the Robovac 11c and 15T, a lot of consideration was given to height and the possibility of having a home with relatively low furniture. Hence, the small size of the two.

They both have a diameter of 12.8 inches and a height of 2.8 inches for vacuuming under low surfaces. The only difference is in the more elegant look of the 15T. But that’s just my opinion as design thoughts are subjective.

Battery and Charging Capacity

What is the use of a robot vacuum if it’s always low on battery and seemingly takes forever to charge? Not much right?

Both the Robovac 11s and 15T have a 14.4V, 24W, 2600mAh Lithium-ion battery. That allows each vacuum to last up to 100minutes of vacuuming time.

The 11s and 15T will fully recharge in 5-6 hours.

Filter System

The 15T and 11s have the same triple filter system that consists of a High-performance filter and a dual layer filter.

eufy Triple Filter System

eufy designed a system in which a pre-filter does the job of trapping larger sized debris thereby preventing unnecessary clogging in the robot. A foam filter was included to trap smaller dirt particles and dust.

The major advantage of this filter design is that dirt of any size or form will be trapped during vacuuming.

Brushes, Suction Power and Cleaning Systems

The brush design in the 11s and 15T are the same. They include 2 sets of side brushes and roller brushes.

We now finally get to a major difference. The suction power of the Robovac 11s is 1300Pa while the Robovac 15T is stronger at 1500Pa. The additional 200Pa gives the 15T an advantage when sucking up more dirt from surfaces during vacuuming.

The cleaning system for both the Robovac 11s and 15T are the same. Except for the increased Suction Power, there isn’t much difference to spot in the cleaning ability of the Robovac 15T from the 11s.

The Robovac 11s and 15T are both good on thin carpets, thin rugs, tiles, and hardwood floors. If you own a pet, the 15T will be more useful in cleaning pet hair from the carpet.

Navigation and Mapping Technology

eufy includes Infrared and cliff sensors that help the robots in venturing across the room. The robots, however, don’t have the technology for mapping rooms or planning straight-line, more efficient paths for vacuuming.

The11s and 15T move randomly, but they still do a good job of covering the area.

Controlling the Robovacs

Two Ways to Start

The eufy 11s and 15T are both controlled with physical remote controls or by the buttons on top of the robot vacuums.

Unfortunately, neither the 15T nor 11s have WiFi connectivity, so you won’t be able to use the eufyHome app or voice control through Alexa.


Yep, maintaining and cleaning robot vacuum cleaners are important for longevity. It’s the same with all electronics.

You’ll want to empty the dustbins on the 11s and 15T after each use. You don’t know what’s been sucked into the dustbin, so you’ll want to empty it out into the trash.

Maintenance also includes checking the brushes and rollers for tangled pet hair or other debris. You’ll want to check filters, side brushes, and other moving pieces to see if they need to be replaced.

Replacement parts are inexpensive, so don’t be afraid to change them out if there’s the possibility of your eufy robot getting damaged. You’ll be able to find replacement parts like these on Amazon.
