Eufy by Anker BoostIQ RoboVac 11S Plus Robot Vacuum Review

To better meet the needs of those who have medium-pile carpet, Eufy offers up the 11S Plus. The RoboVac 11S Plus’s claim to fame is its extra-strong suction system and super-slim housing. Features such as its lithium-ion battery and three-part filter provide reliable performance.

Operating the robot is a user-friendly experience. The remote has five cleaning-mode options, including programmed scheduling. You’ll also appreciate that the filter has a separate access door, and the robot won’t deafen your ears when it automatically increases the suction.

1,500 Pascals of Quiet Suction

You’ll be amazed out how much dirt the Eufy RoboVac 11S Plus Robotic Vacuum pulls from your carpet.

Now, the 11S Plus can reach a praiseworthy 1,500 pascals of suction thanks to Bostic Technology, which kicks up the robot’s suction within seconds whenever there are heavy areas of dirt. That extra oomph is even delivered quietly at a mere 55 decibels.

A Solid Brushroll System

The three-part brush system is reliable. Two side brushes spin rapidly to help the robot collect debris along its cleaning path. The double-V brushroll loosens and lifts stubborn dirt from low and medium-pile carpet, and the guard comes off without needing a tool.

Shorter Than Most

Standing only 2.85 inches tall, the RoboVac 11S Plus is one of the shortest robotic vacuums you can buy. At this height, the robotic vacuum is able to travel where many others can’t, including the floor underneath bed frames, kick plates, and living room furniture. With its pinstriped housing encased by glossy, protective tempered glass, the robot even manages to look good while cleaning.

The 2.85″ tall RoboVac 11S Plus glides underneath beds and sofas with ease.

Infrared Sensor Navigation

Effective yet simple. The Eufy RoboVac 11Splus is equipped with multiple infrared sensors that help it navigate. Some of these sensors detect objects while others look for drop-offs like stairs. Sliding and hanging rarely occur since the robot has a set of treaded wheels that boast a climbing capability of 0.63 inches.

Putting the robot in auto-clean mode is easy to do from the onboard control panel. However, Eufy included a remote that lets you choose from three other modes – spot clean, edge clean and quick clean. Setting an automatic cleaning schedule is easy due to the remote’s display screen.

Large-Capacity Dirt Bin

Debris won’t increase the time it takes for the 11S Plus to clean your floors. The bin can hold 20.3 ounces worth of dirt.

During daily floor maintenance, it’s highly possible the bin will only need to be emptied once. A handle-integrated release button makes it a breeze to slide out the bin and dump its contents.

The RoboVac 11S Plus is only 2.85″ thin but packs 1500Pa of suction strength.


Consolidated Filtration

The RoboVac 11S Plus traps the majority of allergens that are suctioned. The filtration system is comprised of three layers, two of which are combined into a single pre-filter that captures large particles before they reach the main high-performance filter.

The filter set is reachable through a separate access door on the dirt bin, so large debris won’t contaminate it.

100 Minutes of Runtime

Eufy chose to use a 2,600 mAh lithium-ion battery, which is powerful enough to produce the runtime needed for larger homes. On a full 5 to 6-hour charge, this battery will last for 100 minutes.

When it’s time to recharge, off to the dock the 11S Plus goes until you send it out for another run.

Budget-Friendly But Not a Letdown

Often, manufacturers sacrifice even the most basic of performance features to give consumers a robotic vacuum at a rock-bottom price, but this isn’t the case here. Eufy’s 11S Plus is a robot vacuum with strong suction, a long-lasting battery charge and all the cleaning modes that should come standard on a robotic vacuum.

How well did Eufy build its other robot vacuums, and do economically priced models from other brands measure up? Take a look at how these four robots compare to the RoboVac 11S Plus.

Eufy RoboVac 11S Plus vs. Eufy RoboVac 11S (Slim)

When it comes to suction strength, the 11Splus has the edge – You’d be amazed at what a difference 200 extra pascals can make. To the Eufy 11S’ credit, it shares the same low-decibel output and automatic suction increase. Additionally, both models are equipped with an efficient double-V brushroll and two side brushes.

Eufy RoboVac 11S
Eufy RoboVac 11S

Eufy kept the 11S Plus the same size as the Eufy RoboVac 11S (Slim), and that’s a positive point since both are only 2.85 inches tall. Each one has a treaded pair of wheels that can climb thresholds up to 0.63 inches. While their scratch-resistant tempered glass top gives these robotic vacs a high gloss, the pinstriped housing on the 11S Plus differs from the 11S’ brushed black finish.

When presented with obstacles or stairs, the 11S Plus and 11S (Slim) are programmed to turn away and move in another direction. To spot these dangers, they rely on infrared sensors. Both come with a remote control that allows you to pick from auto, edge, spot-clean and quick-clean mode. You can even set a daily cleaning schedule.

Eufy RoboVac 11S

Although they are slim, these robotic vacuums have a dirt capacity of 20.3 ounces. The bin is easy to remove thanks to its release button. Inside the bin’s top compartment, there’s a two-piece filter unit that provides three layers of protection against allergens.

Eufy put a 2,600 mAh battery in both robots. Due to the battery’s high capacity, the 11S Plus and 11S (Slim) have a working time of 100 minutes and a recharge time of 5 to 6 hours. They also automatically dock to the charger when the battery needs to be replenished.

Eufy RoboVac 11S Plus vs. Eufy RoboVac 30C

Scheduling, four cleaning modes and infrared navigation are shared features of the 11S Plus and 30C. However, the 11S Plus only has a remote while the Eufy 30C offers Wi-Fi connectivity, and the 30C works with the EufyHome app, Alexa or Assistant. With the 30C, you can issue voice commands, locate the robot and receive notifications, and it comes with magnetic strips to create no-entry zones.

Eufy RoboVac 30C
Eufy RoboVac 30C

Eufy chose pinstripes to jazz up both robotic vacuums, but the 30C’s are more pronounced. Each robot only measures 2.85 inches in height, allowing them to reach where taller robot vacuums cannot. They’re also equipped with heavy-duty wheels that maintain traction even when running across thresholds of 0.63 inches.

Suction strength is a tie. Both generate 1,500 pascals of suction when their manual max suction or automatic suction boost function is activated. Thankfully, neither robot is loud – Each one tops out at 55 decibels. They also have a double-V brushroll along with two side sweepers.

Eufy RoboVac 30C

A large dirt bin is included with both robots. The Eufy 11Splus and the 30C can hold approximately 20 ounces of dirt and debris in their slide-out bins. You also get a three-piece filtration media with a pre-filter, a sponge layer and a high-efficiency cartridge.

These robotic vacuums have a runtime of up to 100 minutes. Their 2,600 mAh lithium-ion battery takes 5 to 6 hours to recharge when fully depleted. As with any robotic vacuum of value, the 11S Plus and the 30C automatically drive to the dock when their battery gets low.
