We’ll just come right out and say it. This one is the apple of our eye. It’s a nice mix of affordability and high performance.
You get a nice, solid robot vac for a good price:
- Suction Power —1300 Pa, quiet at 55 db
- Auto, edge, spot and single room
- Auto dock and recharge
- Affordable, under $250
- Comes with 1 year warranty
- 2600 mAh battery with 1 hour 40 minute run life
- Scheduling and IR remote control
- Slim body
- Does not have wifi
- Has cliff sensor and carpet boost
Although it’s a bump and track robot, its smaller body and sleek shape give it really good maneuverability. It very rarely gets stuck —if ever. But if it does, it has has the ability to free itself by rocking back and forth or backing up.
The 11S is shorter than most of the competition. At 2.85 niches in height, it can fit under furniture better, and under your bed. This means it can collect more dust and dander without getting trapped.
It comes equipped with a long battery life (1 hr 40 min) and a single bristle combo brush. This blade style easily loosens debris from short rugs, and works well on hard floors too.
The Euyfy 11S boasts 1,300 Pa of suction —which means it has a bit more pull than some of the competition. It may not make a dramatic difference, but it’s good to know it’s above par.
All-in-all, the RoboVac 11S is a quality, low-cost robot vacuum. But keep in mind that It doesn’t work with boundary markers. That means you will have to set up physical boundaries to keep it from going into other rooms or spaces.
Affordable robots like the 11S tend are not built to last as long as high end models. But Eufy always honors its 1 year warranty, and often goes above and beyond when it comes to fixes.
