Roidmi Eva test: an efficient robot vacuum cleaner, but not very thorough


Convenience of use

The Eva makes us think of a small futuristic tank. Made of white and black plastic, topped with an imposing bumper, this robot is ready to do battle with the dust. And to do this, a laser rangefinder installed on its hood allows it to move around in its environment and detect obstacles in its path. This turret, on the other hand, makes it reach 10.6 cm in height, which can be complicated to pass under certain furniture, unlike the 7.7 cm of the Yeedi Vac 2 Pro.


Under its hood hides a dust collector with a capacity of 300 ml, to which is hung a HEPA filter. For comparison, it is half that of the Dreame L10 Pro which peaks at 600 ml. The robot vacuum cleaner is therefore obliged to multiply the back and forth to empty this collector into the dust bag nestled in the base. These back and forth movements are also necessary to moisten the mops of the Eva, because the robot does not carry any water tank. Next to the dust bag, the station has two bins of 4 l each: one filled with clean water and one which is responsible for recovering the dirty water after cleaning.

To collect the waste, a large brush takes place in the belly of the Roidmi. Made of rubber and nylon bristles, it is effective on all surfaces, but we will come back to this when discussing the results of our suction tests. A small side brush is also installed on the side of the device and takes care of bringing the dust towards the central brush.

Two mops can be installed under the robot vacuum cleaner. The Chinese manufacturer informs us that they perform 180 revolutions per minute and exert a pressure of 12 N on the ground. They are attached to the device with two magnets and detach from the support to go to the machine. The user therefore does not have to wash them by hand, unlike the pads of the Dreame W10, for example.

Finally, three buttons sit on top of the robot to launch a complete or targeted cleaning, or even to ask it to return to the station. Others are placed on the latter and order the Roidmi Eva to empty its collector, moisten its mops, return to its base or launch a cleaning. The station also houses a screen that alerts the user in the event of a maintenance problem. Icons appear in particular when the dust bag is full, just like the waste water tank, or when the battery is low and there is a shortage of clean water. But the robot vacuum offers many more options when the user goes through the Roidmi mobile app.

Connectivity and app

The robot pairing procedure is very simple. You must select the device from the list of products offered, then connect the vacuum cleaner to wifi. The Eva then appears on the home screen and we immediately have access to its battery level and a summary of the cleaning session in progress. Four suction powers are offered by the manufacturer, as well as different cleaning modes: wash and vacuum, only wash or only vacuum. Namely that when the mops are installed, the robot cannot help but wash the floor. Indeed, he is unable to lift his two skates and will therefore have to go around the mats.

As with the majority of robot vacuum cleaners, the user can define the area to be vacuumed. It selects one or more rooms in the home, draws a specific area or restricts the space to be cleaned. An option called Point, redundant and not very useful we must admit, is also available and automatically draws an area of ​​1.6 x 1.6 m.

Several options are available by clicking Next, such as routines, multi-stage, or device component health. The app then alerts the user when the sensors need to be cleaned or the filter changed.

For our test, we installed the Roidmi application, but you should know that the user has the choice between it and Xiaomi Home. The latter is preferable for people with other connected objects from the Xiaomi ecosystem, because it allows you not to multiply the apps on your mobile. Above all, the Xiaomi app is much more comfortable than the second: the menus are more intuitive, as are the main controls. Indeed, the Roidmi app deserves some improvements to make it easier to find the options and features of the robot.

As we mentioned earlier, the docking station empties the robot’s dust collector, even if it is possible to deactivate this option via the application. The user therefore does not have to worry about this step; he simply has to change the dust bag once it is full.

This configuration is all the more comfortable as the collector is not very easy to remove and the residues contained inside sometimes fall inside the robot. Note that debris can also be sown around the docking station, on the Eva’s return path. In order to remedy this defect, Roidmi makes it possible to unclip the station’s interior tray to clean it with water and prevent the proliferation of bacteria.

This gray tray can be unclipped to be more easily washed.

Finally, we wanted to test the filtration performance of the robot vacuum cleaner. Remember that it is equipped with a HEPA filter located in the dust collector. To do this, we scatter 20 g of cocoa on the ground and ask the device to swallow them. Once its task is complete, it naturally returns to its base to empty its dust container. We then weigh the filter again, and what a surprise to find that there is no longer any cocoa residue. Although the Roidmi’s filtration performance is excellent, it does not relieve the user of having to clean the filter with clear water when it is too clogged.

Navigation system

From the first cleaning sessions, we noticed that the Eva returned to its base very easily. Each time, he begins by going around the room, then covers the rest of the surface by making zigzags. Its movements are fluid and its trajectory unhesitating.

To better understand its navigation system, we scattered piles of sawdust in several strategic places: under the radiator, in a corner of the room, next to the trash can, under the table, under a curtain and even in the middle of the room. middle of the lab. The Eva begins its run and we let it operate alone in our laboratory. After a few minutes, we come back and unfortunately discover that most of the piles are still there.

The robot indeed considers the curtains as walls and therefore does not bother to push them, even slightly, to vacuum behind them. Despite its side brush, we also find a lot of sawdust in the corner of the room and under a piece of furniture; a place that didn’t seem particularly difficult to clean. Finally, streaks are apparent around the base and even in the middle of the room…

Now we observe the behavior of the Eva against certain obstacles. Roidmi claims in particular that his robot is able to climb over obstacles of 20 mm – 15 mm when equipped with mops. We confirm the statements of the Chinese manufacturer since the vacuum cleaner passes without difficulty above the bars of chairs, as well as on large cables. However, he decides to swallow the finer ones, at the risk of blocking his brush.

Strong points

  • Very complete docking station.

  • Decent suction performance.

  • Good stamina.

Weak points

  • Average surface coverage.

  • Poor washing performance.

How does grading work?

With its Eva, Roidmi promises an almost autonomous robot vacuum cleaner. Indeed, the device vacuums and washes the floor, while its station takes care of emptying its dust collector, moistening its two mops and washing them after the cleaning session. Equipped with a laser rangefinder, the Eva navigates methodically. On the other hand, it struggles to suck in corners and under certain pieces of furniture, and its pads are not very effective.
