Since the introduction of its original Robovac 11, Eufy has been making reliable and affordable robot vacuums. We've come to expect decent but incremental improvements along the way. The Robovac 11S (available at Amazon) bucks that trend. It's slimmer (that's what the S stands for), quieter, and picks up more dirt—particularly in spots where other robot vacuums struggle. Now that's a winning combination.

At a glance

• Picked up 11.6 grams of dirt per run—more than some popular iRobot models
• Took a long time to clean—over two hours for our obstacle course
• No virtual walls or barriers to control where it cleans
• Quiet operation—55dB

Performance

Changes

Eufy learned from past models and user feedback to create a better robot vacuum.

As far as dirt pickup goes, we found the 11S to be up to snuff. Its slimmer profile, just 2.85 inches tall, means it can get further under couches and toe kicks. Combine the lower profile with improved suction, and you get a robot vacuum that can get to and pick up dirt.

On average, it picked up about 11.6 grams of dirt and debris per run. We know that 11 grams sounds like a paltry amount, the same volume as a tablespoon, but the 11S can be programmed to run everyday automatically, so we're taking the long view. Over the course of a week, you can expect the 11S to fill up with 80 grams of dirt and pet hair. Those kinds of numbers rival a light manual cleaning from a full-sized vacuum.

Height

Standing less than 3 inches tall, the 11S is one of the thinnest robot vacuums on the market.

The Competition

Typically, the 11S sells for around $200, and this is very competitive price range. There are a lot of robot vacuums at this price point, and they all offer different sets of features.

A4s

The A4s gives the Eufy Robovac 11S stiff competition.

iLife A4S: The A4S picked up more dirt, but it's also more noisy.

Ecovacs Deebot N79: The N79 is a little more expensive, but you can get a version with smart connectivity. It did get stuck more often than the 11S.

Eufy Robovac 11c: The 11c is just like the original 11, but with smart connectivity. The ability to turn it on from anywhere in the world gives the 11c an edge in usability over the S. But it is more expensive.

Who should buy this?

If you bought the Anker Robovac 11 or one of the early Eufy's, the 11S is different enough and better enough to warrant an upgrade. New buyers will also appreciate what the 11S has to offer: great dirt pickup, a lower profile, and quiet operation.
