Ecovacs Deepoo D56 review

The Ecovacs Deepoo D56 is the second vacuum cleaner robot that we have had in the last few months. Although this model is only the second cheapest floor cleaning robot in the Ecovacs portfolio, it offers everything I expect from an average robot.

Design and Technology

The red Deepoo D54 is acceptable, the golden yellow D58 is kind of elegant, but it is hard to say anything nice about the color of the Deepo D56. This pink is extremely harsh. Although my daughter (4) loved it as any other pink objects, it is not appropriate in an elegant home. Most visitors in our house said that it is ugly, and I agreed with them, but over time I got used to it. I would probably prefer the yellow if I was to pick from the three, but I can imagine a niche where this color is considered attractive.

Ecovacs Deepoo D56

The plastic used in the housing of the robot is not colored in the material, but painted on the surface. This means that any scratches will be more visible than on most of the other robots. At least the light color camouflages the dust that will settle on it after a while.

Painted on the outside

Although the general shape and size of the robot (33.5×9.8 cm, 3 kg - 13.2×3.9 in, 6.6 lbs) is very similar to that of the more expensive models, the front bumper is larger and more visible. When I unboxed the robot I thought that the front bumper was broken. The sides of the bumper are not held away by springs, so the bumper can be tilted to any direction. After a few runs I realized that it must be like that on purpose to ensure better connectivity while on the dock.

Charging is provided by the contacts on the front, while the black rubber strip on the bottom of the bumper prevents the robot from ruining the furniture it bumps into. The small openings on the right hold an IR distance sensor for better wall following.

The 0.4 l (13,5 fl oz) dust bin of the robot is hidden under a removable door. Unlike in the D76, the cover comes off totally, and the sensors forcing closed lid position are also from the cheaper kinds. Although I could not compare them side by side, the dust bin seems to be identical to the bin in the larger model. Despite the cheaper design, the robot is equipped with a full bin indicator. The cover opener doubles as a feedback light.

User interface

The user interface looks a bit different from the UI of the D76, but offers almost the same functionality. The LCD display is indeed the same as in the more expensive model, only the design of the buttons were changed to a style that is cheaper to build. Two buttons on the left provide up and down functionality to raise or lower values, while the third one between them gives access to the clock and scheduling. The buttons on the right are used more frequently. The one on the top is the power button to turn the robot on and off, the one in the middle is a mode selector, and the bottom one is a play/pause button to start and stop the selected program. The user interface is simple, easy to use, and thanks to the backlit screen, it is easy to read.

The top of the dock covers the user interface

Unfortunately it is not without a big design flaw: when the robot is on the dock, the screen and the buttons are fully covered by the upper part of the dock, so the robot is totally uncontrollable when parked (no remote).

Bottom of Ecovacs Deepoo D56

The bottom of the robot is simple and straightforward. The two larger wheels on the sides move and turn the robot, the third on the front is only there to support. The side brush on the right side of the robot (left when it is upside down) helps cleaning the floor along walls and furniture.


The 14.5 cm (5.7 in) bristle bar is 3 cm (1.2 in) longer than the one in the more expensive model. The vacuum motor sucks the air through the opening of this brush bar, so to concentrate this force, the opening is surrounded by a small rubber skirt on three sides.

The bar itself is thick, the bristles organized in a wave shape, and it has no rubber squeegees. The bar and the drive motor is connected by a belt. To clean the bar, the covering frame must be removed. Unfortunately it is held in place with 2 screws, that makes this basic maintenance task a bit complicated.

14.4 V 2100 mAh Ni-MH battery

The 2100 mAh Ni-MH battery, hidden behind the main brush, right under the dust bin, provides enough juice to power the robot for about an hour. According to the manufacturer this allows the robot to keep a 40 sq m (430 sq ft) area clean.

Drop sensor

The Deepoo D56 is equipped with 3 drop sensors to avoid the robot falling at the stairs or other drops.

Docking station

All Deepoo robots come with a docking station that automatically charges the robot while it is not in use. The Ecovacs dock is very unconventional, as it has a large covering part that protrudes above the docked robot. As I have mentioned, it covers the entire user interface of the robot, making it hard to even start the previously selected program. An infrared LED built into this covering part helps the robot during the docking process.

The Deepoo D56 has no remote control, virtual wall or magnetic strip to limit the territory of the robot. The robot is sold with these three accessories in the Deepoo D58 bundle.
