The eufy RoboVac 11S is a slimmed-down version of the original RoboVac 11. It’s one of the most affordable robot vacuums eufy has in its arsenal. This little robot is best for maintenance cleaning on hard floors and low-pile carpet.

It has a lot going for it, including the very slim profile that allows it to get under more furniture and other low points than its bigger brothers.

RoboVac 11S Review India

What do you get with the RoboVac 11S?

Inside the box, there’s the vacuum, charging station with AC power adapter, a remote control, 2 AAA batteries, cleaning tool, extra set of filters, 4 side brushes, and 5 cable ties to wrap up cords that can tangle up the machine.

RoboVac 11S is a powerfull and quiet robotic vacuum cleaner


  • Battery run time: Up to 100 minutes
  • 0.6 L dustbin
  • Noise level ~ 55 dB
  • Dimensions: 12.8” W x 12.8” L x 2.85” H
  • Weight: 5.85 pounds
  • Warranty: 12-month limited


Setup and usage

To prepare the 11s for cleaning, you must first attach two of its side brushes. These snap onto two studs at the front of the vacuum with little effort. Then turn it on—the switch has been moved from the side to the bottom of the vac—and place it on the charging pins of its dock. Eufy says its high-capacity Li-ion battery will deliver up to 100 minutes of cleaning on a full charge.

The 11s offers several cleaning modes, all of which can be activated from the remote. Single Room mode intensively cleans a specific area for 30 minutes and is best used in a specific room with the door closed. In Edge mode, the 11s reduces its speed to approach a wall and then cleans along it for 20 minutes before returning to its dock. In Spot cleaning mode, the 11s will clean an area of concentrated dirt in a spiral for two minutes. With Manual mode, you can direct the vacuum to an area using the directional buttons on the remote.

Less than 3 inches tall, the 11s can easily get in and out from under low-clearance furniture.

For general maintenance cleaning, though, your best choice is Auto mode, which automatically chooses different modes as needed until the job is done. I used it for daily cleanings of my approximately 400-square-foot downstairs living area. The vacuum had no problem managing the three types of flooring there—carpet, hardwood, and linoleum—or transitioning over a lip between the living room and foyer. It usually covered that space completely without needing a recharge. Because the 11s will move in a straight line until it bumps into an obstacle and changes direction, its cleaning pattern can seem haphazard. But it never failed to take at least one pass over every area it could reach.

Despite regularly being littered with pet hair, food crumbs, stray bits of paper, and other detritus, the 11s left my floors even cleaner than the original RoboVac 11. That’s no doubt due the increased suction (1300Pa) and new BoostIQ technology, which automatically increases suction power on carpeting. Eufy's robot vac also did a better job of avoiding stray articles on the floor than the RoboVac 11, which meant I could leave it unsupervised for longer periods of time. Depending on how dirty the floor was, I could typically get through two cleanings before I had to empty the dustbin, so it’s probably big enough to handle one cleaning of a single floor in a larger house.

The Eufy RoboVac 11s comes with a physical remote control with a monochrome display. 


Four cleaning modes with scheduling

  1. Auto
  2. Spot
  3. Edge
  4. Single room

On the remote, you can direct the RoboVac 11S to clean with one of 4 different modes. Auto mode works with the scheduling feature on the remote so you can direct it to clean at set times on different days.

Each mode has different timed cycles, with auto being the longest. Spot clean and auto mode are customer favorites.

BoostIQ and suction power

BoostIQ allows to auto-adjust suction power depending on the floor type

When you first start the RoboVac 11S, it will be on BoostIQ by default. This is an auto-adjusting suction feature. More suction the thicker the carpet. Less for hard floors. You can turn this off and choose a specific amount of suction if you’re not seeing the results you want.

The edge clean feature works well for capturing those dust bunnies that hang out at the baseboards. The round shape allows the RoboVac to reach corners as well as some of the square models. The brushes that sweep out in front of it help with that.

Some customers recommended using auto mode for the main cleaning, then switching to edge mode to better clean the corners.

What do customers like about the RoboVac 11S?

As one of the best-selling robot vacuums with tons of positive reviews, it’s clear that customers really like this machine. By far, the favorite aspects of this vacuum were its ease of use and affordability. Another favorite feature was the low profile, with several people mentioning how the vacuum got into places they never thought to clean, like under shoe racks, TV stands, etc.

Customers like how quiet it is. The low profile of RoboVac 11S is it's another advantage.

Several customers mentioned how quiet it is. At 55 dB, it’s no louder than a normal conversation. People who work at home liked that they could be on a conference call and not be disturbed with it running in the background. If you’re trying to sleep or watch a quiet TV program or something, it might be a little distracting.

Where some robot vacs have issues going over thresholds between rooms, customers reported that this machine just kept on trucking, even going from hard floor to shag carpet. While it did well over most rugs, a few customers said the brushes got tangled on long rug tassels. They recommended picking up rugs with tassels before running the RoboVac 11S or tucking the tassels under if it’s a big area rug.


If you’re looking for an affordable, no frills, quiet robot vacuum, the eufy BoostIQ RoboVac 11S is a great option. It’ll do best in homes that are relatively uncluttered with simple layouts and on hard floors or low-pile carpeting.
