The Eufy RoboVac 11S robot vacuum packs a punch of suction that’s steady and long-lasting, using BoostIQ technology to periodically up its suction strength.

In order to keep dust emissions at a minimum, the robot vacuum contains three filtration media. You can even point and click the remote to drive the robot or start a specific cleaning session. Thanks to its slim design, you don’t have to shuffle your furniture to help the vacuum.

Carpets are no issue for the Eufy RoboVac 11+ with its wide-width brushroll and BoostIQ technology.

As 11 sensors help guide the robot’s path, the scratch-resistant cover and the durable bumper protect the robotic vacuum from sudden obstacles. Like the 11S, the 11+ comes with a remote control and a triple-filtration system.

Powerful Debris Pickup

Eufy RoboVac 11S
No need to go behind and clean what the RoboVac 11S left behind on your carpet. This robotic vacuum produces an impressive 1,300 pascals of suction. The second generation of BoostIQ technology used in this robot increases the suction automatically in a matter of seconds, never exceeding 55 decibels.

To give you a thoroughly clean medium-pile carpet, the 11S is equipped with a stiff-bristled brush roll. Plus, there are not one but two spinning brushes that extend from the edge of the robot.

Eufy RoboVac 11+
This robot vacuum can suction debris from almost all flooring, including standard residential carpet. It generates 1,000 pascals of suction at only 60 decibels. It is also the first of Eufy’s robot vacuum cleaners to offer the latest BoostIQ technology.

Even when lifting large debris, the vacuum’s suction doesn’t wane. The inlet is reinforced, lending it durability and optimizing the 11+’s airflow. Two side brushes flank the RoboVac 11+, so it can draw in dirt and dust.

Conclusion: There’s no doubt that both robot vacuums offer strong suction with the 11S pumping out 300 more pascals of it. Each vacuum uses auto-engaging BoostIQ technology. With the addition of a brush roll, they can handle carpet piles as high as 0.87 inches.

All-Encompassing Filtration

Eufy RoboVac 11S
Most robotic vacuum cleaners only have one filter in their dust compartment. However, the RoboVac 11S has three different types of filters. The combo filter consists of a protective pre-filter and a foam filter, and the high-performance filter takes care of allergens and other small particles.

The dust box itself holds all the crumbs, dirt and debris the robot suctions, and it certainly does hold a lot. With a capacity of 0.6 liters, you will probably only need to empty the container once every day or every other day.

Eufy RoboVac 11+
The same set of filters found in the 11S also come standard with the RoboVac 11+ – the dual-layer pre-filter and foam filter as well as the high-performance filter. This means contaminants of all sizes stay trapped in the filtration system instead of becoming airborne.

These filters are located in the 11+’s dust container, which has a 0.55-liter capacity. Dumping its contents is a mess-free process. As opposed to an open container, the box has a hinged lid to keep debris secure while you carry the box to the trash can.

Conclusion: Smartly, Eufy decided to stick with the same set of filters for both the 11S and the 11+. After all, if it’s not broke, why fix it? While each robot vac’s dust container has a large capacity, the 11S’ container is slightly bigger.

Daily Scheduling and More

Eufy RoboVac 11S
You have many ways to customize the Eufy RoboVac 11S’ performance. Pick up the included remote control and program a cleaning schedule that operates at the same time on the days you specify. Alternatively, you can engage perimeter, spot or single-room mode.

Whichever mode you choose, the suction won’t cut out prematurely. Due to the lithium-ion battery inside of it, the Eufy 11S can run for 100 minutes. Since the robot is designed to auto-dock, you don’t have to be inconvenienced by placing it on the charger yourself.

Spot, single-room, perimeter – All three cleaning modes are available on the RoboVac 11+. You can also set a weekly schedule and steer the robot’s movements with the controller. If you want to put the vacuum away, you can do so without getting up by pressing the home button on the remote.

The 14.4-volt lithium-ion battery in the 11+ lasts for 100 minutes between charges. Even though the dock button is handy, the self-dock blows the manual option out of the water in terms of convenience.

Conclusion: These robotic vacuums have a cleaning mode for almost every mess from spot mode that cleans up small piles of debris to perimeter mode that keeps wall edges dirt-free. Both Eufy robotic vacs come with a remote control and a lithium-ion battery that lasts for over 1.5 hours.

Intelligent Movements

Eufy RoboVac 11S
Its brushed black finish makes the RoboVac 11S an attractive appliance, but there is plenty going on underneath the vacuum’s hood. Infrared sensors detect obstacles in the vacuum’s path while drop-sensing technology prevents falls.

This model is equipped with a pair of sturdy wheels that can traverse 0.63-inch thresholds. It’s also super-thin at only 2.85 inches. If the robot attempts to slide under furniture that sits too low to the ground, the anti-scratch coating on the tempered glass cover will keep the vacuum in pristine condition.

Eufy RoboVac 11+
Eufy didn’t skimp on sensors with this robotic vacuum. The robot boasts a suite of 11 infrared sensors that keep an eagle eye on obstacles. Also, the gunmetal gray robot vacuum also has the same fall-detecting software that the 11S uses.

With its rubberized bumper and tempered glass cover, you won’t ever see any battle scars RoboVac 11+. Its two wheels can handle inclines as high as 0.59 inches, and the robotic vacuum has a maximum clearance of 3.1 inches.

Conclusion: The bumper, anti-scratch cover, and rugged wheels make it evident that Eufy built the 11S and the 11+ to last. Although the 11S has slightly bigger wheels, the wheels on the 11+ are still oversized. However, the RoboVac 11S has the advantage when it comes to height.

11S vs 11+: Spectacularly Streamlined

It’s incredible to think that Eufy managed to compile so many great features into two affordable robotic vacuum cleaners, like the BoostIQ technology integrated into both robots. A reinforced suction inlet wards off damage and the brush roll digs deep into medium-pile carpet. Plus, two side brushes widen the vacuums’ cleaning path.

These robot vacuum cleaners filter the contaminants that cause allergies to flare, and they do it without making a ton of noise. Then, there is the powerful lithium-ion battery, which gives a working time unrivaled by other leading brands. Of course, the remote makes it easy to access all of the robotvacs’ cleaning modes and scheduling function.

With suction strengths of 1,300 and 1,000 pascals, the 11S and the 11+ are mega-powerful. Each one has a high climbing threshold and a large-capacity dust box. If you thought the 3.1-inch height of the 11+ was short, Eufy managed to shave 0.25 inches off the 11S to give it more freedom of movement. The Eufy RoboVac 11S and Eufy Robovac 11+> are well-built robots that take vacuuming to the next level.
