What is common between the Eufy RoboVac 15C and Eufy RoboVac 11S
- Both have a short 7.2 cm body that fits under most furniture.
- Both are quiet when vacuuming.
- Have strong suction.
- Both Eufy can clean carpets up to 16 mm height.
- They have the same battery capacity.
- Both can clean for 100 minutes.
- The same amount of accessories in the box.
- Boost IQ automatically increases suction power when needed. Supported by both models.
- Cleaning performance. Because of the same size of wheels, strong suction and Boost IQ, both Eufy 15C and 11S perform well on carpets not thicker than 16 mm and bare floor. However, they are not able to provide deeper cleaning on carpets.
What is different?
- Eufy 15C supports Wi-Fi and comes with an app. In the app, you can start/stop the robot, schedule it, switch between cleaning modes, manually control the Eufy like a radio car.
- Eufy 15C is integrated with Alexa-enabled devices and Google Home.
- Price. The Eufy 11S costs $70 cheaper though it lacks Wi-Fi, app and smart voice assistants compatibility.
Which Eufy to buy?
In terms of cleaning performance, both Eufy 15C and 11S do a good job. If you own Alexa or Google Home and want your robot to start/stop from hearing your voice commands, go with the Eufy 15C.
If you do not need the app to control the vacuum consider buying the Eufy 11S. It is budget and offers enough to satisfy your needs.
Please note: if you have thick carpets, have a look at other models such as the Roborock Xiaowa C10 or Roborock Xiaowa E20 since Eufy is not able to do the job on medium and high-pile carpet flooring.
