Eufy BoostIQ RoboVac 11S Plus Robot Vacuum Review & Comparison

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.

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.

Remote Included

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.

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 robo vacs, 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 Plus vs. 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.

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 11S Plus vs. 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.

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 vac of value, the 11S Plus and the 30C automatically drive to the dock when their battery gets low.

Eufy RoboVac 11S Plus vs. iRobot Roomba 690

The Eufy RoboVac 11S Plus is powerful with its 1,500-pascal suction production, but the iRobot Roomba 690‘s self-adjusting plate gets its suction closer to the floor. Instead of a double-V brushroll and two side brushes, the Roomba 690 is equipped with two multi-surface rolling brushes and one side sweeper. However, both detect and respond to concentrated dirt by amping up their suction.

Eufy RoboVac 11S Plus vs. iRobot Roomba 690

White pinstripes on a black background and a black-and-silver finish make the 11S Plus and 690 quite different in terms of appearance. Both have a bumper and treaded wheels, but the 690 is about 2 pounds heavier, which is the reason iRobot built a tote handle into it. Since the 11S Plus has a tempered glass top, it’s less likely to get scratched.

Both robots can clean for long periods without their bins needing to be emptied. Their respective pop-out dirt boxes share approximately the same sizeable capacity. However, the RoboVac 11S Plus’s three-layer filtration system is more efficient than the Roomba 690’s AeroVac filter screen.

While Eufy and iRobot selected a lithium-ion battery, the battery inside the 11Splus has a higher capacity – 2,600 mAh to the 690 battery’s 1,800 mAh. Therefore, the 11S Plus can vacuum for 10 minutes longer than the Roomba 690. Regardless, both models will auto-dock when their battery must be recharged. Each one navigates with its own array of sensors, but the 11S Plus is 0.75 inches shorter.

Although the 11S Plus comes with a remote and both robots have a spot-clean and scheduling function, the 690 works with the iRobot HOME app. The Roomba 690 offers more localized controls, a dual-mode boundary wall and virtual-assistant pairing. However, you can’t direct it to edge or quick clean like you can with the 11S Plus.

Eufy RoboVac 11S Plus vs. Ecovacs Deebot N79S

Even though the Eufy RoboVac 11S Plus and the Ecovacs Deebot N79S provide variable-suction, the only way to engage it on the N79S is manually. The 11S Plus also generates 500 more pascals of suction at a lower sound of almost 10 decibels. However, the N79S has alternating rows of bristles and rubber sweepers on its V-patterned brushroll.

Eufy RoboVac 11S Plus vs. Ecovacs Deebot N79S

The Deebot N79S’ housing is designed with a lightly brushed finish instead of white pinstripes. Both robots have a durable bumper and drive on heavy-duty wheels, but the 11S Plus’s are more robust and able to traverse higher thresholds. The 11S Plus can also fit under lower clearances, measuring 0.26 fewer inches than the N79S.

As far as dirt capacity is concerned, the Eufy RoboVac 11S Plus wins. It can hold twice the amount of debris than the Deebot N79S can, which means downtime is drastically reduced. When it comes to their filter, these robots are evenly matched as both have a three-part high-efficiency filtration cartridge.

Each robot vacuum comes with a remote control, and both use infrared sensor technology to move in a random pattern when set to auto-clean mode. Nonetheless, you can access the N79S’ direct control, spot-clean, edge-clean and scheduled mode not only with its remote but also on the Ecovacs app. Additionally, the N79S is compatible with Alexa and Assistant.

These robo vacs do well in large homes thanks to their 100-minute runtime. When the 2,600 mAh battery gets low, both robots will automatically return to their dock. The charging time for the 11S Plus and N79S are average, but the RoboVac takes an hour longer to recharge than the Deebot robot.
