Xiaomi Roborock S55 smart vacuum: classic and compact

The Xiaomi Roborock S55 looks like your standard robotic vacuum cleaner: it's circular in shape and quite compact. The device measures 13.9 x 13.78 x 3.8 inches and weighs 3.5 kg.

On the top, you will see the three main control buttons: on/off, charging and spot cleaning. In the middle of the top lid, there is a small "tower" housing the laser sensor that allows the vacuum cleaner to map out your home's interior.

Underneath, there are two large wheels, the main brush and a side sweeper. The lid opens up easily revealing a cleaning tool, dust box and HEPA filter.

One of the main convenience factors when using most of Xiaomi's smart home appliances is easy control via the dedicated Mi Home app. Once you've downloaded and installed the app on your smartphone and registered an account, you will need to pair it with your vacuum. When everything is set up, you will be able to control and monitor the Xiaomi Roborock S55 right on your smartphone. The modes on the main screen are Dock (the robot returns to the charging base), Pause/Start and Spot Cleaning. You can also use these same controls manually — as mentioned above, you will find them right atop the vacuum cleaner. But there is a whole lot of other useful data in the app like house mapping, duration of the current session, battery status, the area already cleaned, etc. You will also be able to set the timer, choose a cleaning mode, set up the Do Not Disturb Mode, receive email notifications about the robot's performance and more.

You will see reports of cleaning sessions in Cleaning History and will be able to check if the brushes and filters on the vacuum are working well in the Care section.

Another feature that makes the S55 stand out is the extensive use of sensors. There are 13 sensors located on the vacuum cleaner, which help it navigate around any interior, watch out for walls, avoid obstacles and falling. Using the information, the vacuum builds a map and used the SLAM algorithm to calculate the best way to clean the area — you will be able see the created plan in the app.

There are 5 cleaning modes: Mop, Quiet, Balanced, Turbo and MAX. There is a rather large 150ml water tank onboard, which is enough for about 50 minutes of wet cleaning. Note that in Mop Mode the vacuum can mop and sweep at the same time. Even though the Roborock S55 robotic vacuum is quite powerful — 2000Pa super suction – it will not be able to conquer stubborn stains, even in Turbo mode.

On the positive side, the vacuum comes with the option called "carpet boost" that automatically increases suction when a carpeted surface is detected. Plus, the vacuum is an impressive climber able to go over obstacles up to 0.78 inches in height: it will easily make its way through thresholds and over doormats and rugs.

The Roborock S55 runs on a 5200mAh battery and can work non-stop for two and a half hours and cover an area of 250 square meters when fully charged. When the battery goes down to 20%, the robot will make its way back to the dock and recharge to 80% before returning to the point where it left off to resume the cleaning process.

Xiaomi Roborock S55 smart vacuum: the verdict

The Roborock S55 is a very strong addition to Xiaomi's line of smart home appliances. Primarily, thanks to the smart incorporation of app control that makes keeping a home clean that much easier and gives the S55 smart vacuum a rightful place in the Xiaomi Mi Home family.

So, let's sum things up.


Xiaomi Roborock S55 smart vacuum Pros

Strong suction power, 2000Pa

Large 150ml water tank

Long battery life with the 5200mAh battery

Multiple cleaning modes: Mop, Quiet, Balanced, Turbo and MAX

Smart and easy control through the app

HEPA filter for getting rid of

Classic design and sturdy build



There are no specific cons that we could find. However, the Roborock S55 model is basically no different than the slightly cheaper Roborock S50. The only difference between the two gadgets is color: the S50 comes in Xiaomi's signature white and the S55 is available in sleek black.
