The Eufy RoboVac 11+ keeps your floors clean of pet hair and fine dust on a daily basis. It can’t replace a traditional vacuum, but will let you do major vacuuming less often. The robot has all the basic functions and is a great choice for a limited budget.


  • Decently cleans pet hair and other dirt on hard floors, low and medium-pile carpets
  • Automatically increases suction on carpets
  • Quiet operation


None: all the features work as expected


Eufy RoboVac 11+ is round in shape, 12.8 inches in diameter. The faceplate is made of dark specular anti-scratch tempered glass and has only one Auto cleaning button and a Eufy logo.

The rest of the robot is made of black plastic. At the rear, there is a semi-transparent dustbin with a release button on top of it. The front part is covered with a moveable bumper that detects collisions with obstacles and protects the robot and furniture from scratches.

On the side there is an on / off switch.

On the bottom of the robot, you will find two big driven wheels on suspension, so the robot can travel on uneven surfaces.

Between the wheels, there is a roller brush in a special compartment, covered with a metal frame.

At the front, there are two side brushes, with two charging pins between them. Between the charging pins, there is a swivel wheel, which spins freely.. Colored with black and white checkers, it is also a part of the movement sensor.

Along the front bumper, there are three cliff sensors, which protect the robot from falling down the stairs.

The height of the Eufy 11 plus is 3.4 inches, which should allow it to go under most furniture for cleaning.

Cleaning Power

The RoboVac 11+ cleans pet hair and other dirt fairly well on hard floors and low carpets. It can miss some spots on a single run, but if you run it every day it will pick up more pet hair and dust than the once per week vacuuming. It’s not as powerful as a traditional vacuum and you still need to do major vacuuming from time to time, but you can do it less often.

Three-stage cleaning system

The robot uses two side brushes to sweep dust towards its main brush. The roller brush agitates dirt on the floor, picks up what the side brushes sweep to it, and transfers dirt towards the vacuum intake. Then the vacuuming fan sucks all the dirt into the dustbin.

This layout can be found in most round robotic vacuums and has proven its efficiency. In the RoboVac 11+ it works just fine and picks up pet hair and dust fairly well.

Main brush

The main brush has V-shaped threads of bristles and plastic blades with cut-offs. It’s covered with a metal frame to reduce the chance of tangling on cords or socks left on the floor.

It gets tangled with hair quite easily and should be cleaned periodically. The robot comes with a cleaning tool to do this job easily.

BoostIQ (automatic power boost on carpets)

The robot can be run in two power modes, standard and maximum. By default, it will automatically increase suction to maximum value on carpets and switch to standard mode when it goes back to hard floors. This feature is called BoostIQ (previously known as Power Boost).

The default behavior can be changed. You can choose between standard, maximum and automatic settings.

Noise levels

The robot is quiet even in the maximum power mode. When it runs in the standard mode, you can barely hear it; it’s quiet enough to watch TV and talk on the phone.

Cleaning along the walls and in corners

With side brushes that swirl and extend beyond the round edges the robot does a decent job of cleaning along the walls. It also gets corners, but not as effectively.


The RoboVac 11+ uses random navigation and mostly bounces between obstacles, randomly changing direction. As it does not have any memory of what it has done or where it will be going, it can clean some areas multiple times while completely missing other spots. However, if you run it daily, it will eventually cover and keep clean the whole area.

Return to the charging dock and to resume cleaning

When the battery runs low or a cleaning cycle ends, a steady blue light on the robot will change to a steady purple-red light and the RoboVac will start searching for its charging base. Once it has a line of sight to the base, it will go straight to it and dock.

Eufy RoboVac 11+ docked

Most of the time it finds the dock and recharges, but sometimes it can fail. To make it easier to find the dock, place the dock flat against the wall and make sure there is 3 ft of free space on either side of it, and 6 ft in front of it.

Single-room cleaning

The RoboVac 11+ cleans best in a single room or an open-plan apartment. You can run it in multiple rooms, but most probably, it will clean one of the rooms thoroughly while missing others. It also will have trouble finding its way back to the charging dock if the battery runs low while it is not in the same room as the dock.

A workaround to thoroughly clean a multi-room apartment is to isolate the robot in one room, then move it to another room, and so on.

Navigating modes

Auto mode

In auto mode, the robot will clean in a random pattern until the battery runs low, then return to the charging dock.

Single room mode

If you run the robot in a small room, the single room mode can come in handy. This is the same as auto mode, but the cleaning time is limited to 30 minutes.

Spot mode

The spot mode allows cleaning a specific area of concentrated dust. Being run from the center of the dirty area, the robot will go out in a spiral fashion for two minutes.

Edge mode

In edge mode, the robot will go until it meets a wall and then go along it for 20 minutes. This does work pretty well to cover the perimeter of the room, where the dust tends to collect.

Ability to go over moldings and carpets

With large and fairly powerful wheels, the RoboVac 11 plus can climb thresholds up to 0.59” high, which is enough to go over most area rugs, moldings and carpets.

Ability to go under furniture

At 3.4 inches of height, the RoboVac 11+ fits under most furniture and therefore can clean in places where you rarely reach with a regular vacuum.

If you have furniture with clearance close to the robot’s height, the robot may try to go under it and get stuck. In such a case, it’s recommended to block these areas off with some boxes.

Going between furniture legs

The RoboVac 11+ detects and avoids obstacles without touching them. However, it can fail to “see” thin furniture legs and may gently bump into them. The front bumper is designed to easily push in about a quarter inch when it hits something. This causes the robot to back up a little, turn and go in another direction.

If you have many chairs, going between them can be a challenge for the robot; however, it will finally find its way out of the maze.

Cliff sensor

The robot has three cliff sensors, which prevent it from falling from stairs. They work fine, and the robot never falls.

The sensors recognize black or very dark floors as a drop and won’t let the robot to go over them. So, if you have dark flooring, you most certainly won’t be able to run the RoboVac 11+ on them.


The RoboVac 11+ has a Li-ion 14.4V 2500mAh = 36Wh battery.

Operating time

The robot’s input power is 28W and on a single charge it can run about 77 minutes in standard power mode or about 60 minutes in maximum mode.

Room coverage

The RoboVac 11+ can effectively clean around 1000 sq ft. You can run it in a bigger area, but it will miss some spots on a single run. You can also split your house into several parts and clean them separately.


It takes 5 hours to fully charge the battery. After the battery is charged, the robot should be left on the charging base to be ready for cleaning whenever you need it.


The battery on the RoboVac 11+ is not replaceable. If the battery fails during warranty period, it will be replaced by the manufacturer.


The RoboVac 11+ can be operated with controls on the robot itself and via remote control.

Controls on the vacuum itself

Using the switch on the edge of the robot you can turn it on / off, and using the button on the top you can run it in auto mode or pause cleaning.

Remote control

The RoboVac 11+ has a remote control with an LCD display, powered with two AAA batteries (included). The remote control requires plain line of sight to the robot since it uses IR signals for operation.

With the remote, you can run / pause the robot in auto, spot, small room or edge mode, send it home or even steer it with arrow buttons.


After setting the correct time on the remote, you can schedule the robot to run every day at a specified time.

Sound notifications

When the robot is stuck somewhere, it will stop and ask for your help with a series of loud beeps.

Before cleaning

As any other robotic vacuum cleaner, the RoboVac 11+ will get tangled on cords, socks or long carpet fringe. For seamless cleaning, it’s advised to pick up all small items from the floor and fold fringe under carpets.


The dustbin is made of half-transparent plastic and has capacity of 0.55 liters, which is enough to hold dirt from one cleaning cycle. If your pets shed a lot, it might be overfilled after the first run, but following that it should be sufficient for everyday cleaning to keep your floors always clean.


The RoboVac 11+ employs three-stage filtration: a sieve, which covers other two filters, a foam filter, and a high-performance pleated filter. The sieve and the foam filter capture most particles and significantly reduce the need to clean the pleated filter.

The triple-filter system works fine and greatly reduces allergy symptoms.


The RoboVac 11+ requires some maintenance for best cleaning results. Aside from emptying the dustbin, you should regularly clean the filters, brushes, sensors and charging pins.

Emptying the dustbin

The dustbin should be emptied after each cleaning cycle. It’s easy to do – press the button to release the dustbin, open it like a book and empty into a trashcan.

Cleaning the filter

To keep maximum performance, filters should be cleaned occasionally. It’s easy to take them out when you empty the dustbin. The sieve and the foam filter are washable, as well as the dustbin overall, but not the pleated filter!

Eventually the foam and pleated filter should be replaced. The robot comes with one spare set of filters.


When the brushes get tangled with hair, they should be cleaned.

The side brushes can be unscrewed and the hair coils around the bases and comes off with a flick of the finger.

When the side brushes are worn, they should be replaced. An extra set of two side brushes is included in package.

To clean the main brush, you should first remove the cover by pulling the two red tabs, and then the main brush underneath pops out easily. It has end caps that also pop off easily, allowing for very easy removal of hair from there also.

There is a multipurpose tool included that has a slicer for cutting hair or other things that wrap around the underneath brush as well as two comb/cleaner devices for getting dust and debris off of the bristles.

Sensors and contacts

The cliff sensors and charging contacts should be cleaned from fine dust once in a while.

RoboVac 11 vs Robovac 11+

The RoboVac 11+ is an upgrade of the RoboVac 11. The new model looks similar to the old one, but has some design and internal changes:


  • The RoboVac 11+ has BoostIQ (Power Boost) Technology, which automatically increases suction power on carpets or can be set to run the whole time in maximum or standard mode. The Max button on the remote is gone.
  • Bigger wheels climb thresholds up to 0.59” high now (RoboVac 11‘s maximum threshold is 0.4 inches).
  • Redesigned rolling brush and suction inlet. The metal frame over the brush reduces trapping cables or fringe, and the cover is now fastened with plastic latches instead of screws for easy removal to clean the brush.


  • The RoboVac 11+ is higher than its predecessor, 3.4 vs 3.1 inches.
  • The RoboVac 11+ has slightly smaller battery (36Wh vs 38.5Wh in RoboVac 11), which is not replaceable anymore.
  • Smaller dustbin (0.55 liters vs 0.6 liters in RoboVac 11).
  • There is no charger inlet on the robot anymore, it can now be charged only in the dock.

Design changes

  • Redesigned front bumper.
  • Filter cover is brown, was blue.
  • Dustbin release button is on the top, there is no separate filter door in the dustbin anymore.
  • Auto cleaning on/off button shape changed from square with rounded corners in RoboVac 11 to rectangle with more rounded corners in RoboVac 11+.
  • There is no place for remote control in the charging dock anymore.
