Dreame Bot D9 Pro is an updated version of the previously released Dreame Bot D9 Max, which we reviewed earlier, as well as a simplified version of the older Dreame Bot L10 Pro and Z10 Pro. Next, I will test this robot vacuum cleaner, and will express my opinion whether it is worth buying. The price at the time of preparation of the review is $400-480, which puts this model to the middle price segment. Let’s go!
Difference between Dreame Bot D9 Pro and D9 Max
First, I will explain what is different about Dreame Bot D9 Pro comparing to the previously released Dreame Bot D9 Max. The difference is not big, but it is there. All the main differences are summarized in the table below:
|Dreame Bot D9 Pro||Dreame Bot D9 Max|
|Control buttons on the body||Start/Pause, Return to base, Spot cleaning||Start/Pause, Return to base|
|Fall protection sensors||6||4|
|Additional||Plastic backing for docking station|
As you can see, the updated Dreame Bot D9 Pro got several small design improvements. But the price difference can be significant. That`s why, with a small difference, it still makes sense to choose an updated model. Now let’s move on to the review of this robot vacuum cleaner.
The robot came in such a branded box:
The package includes:
- Plastic backing for charging base.
- Charging base.
- Power adapter.
- Mopping nozzle with attached microfiber mopping pad.
- Documentation for the robot, translated into several languages.
The delivery set is minimal. There are no spare consumables.
Let`s see how the Dreame Bot D9 Pro is designed. It has rounded shape, made in black and glossy. A wall sensor is installed on the right side of the bumper, and an obstacle detection sensor is in the center. Case height – 97 mm from the floor.
Lidar is responsible for navigation. It is equipped with a spring-loaded cover that prevents the robot from getting stuck under furniture. There are 3 mechanical control buttons on the panel.
The dust collector is located under the top cover. A tool for cleaning the robot is conveniently stored next to it. The container holds up to 570 ml of dry waste. Filtration system based on mesh and HEPA filter.
The bottom of the robot has 6 fall protection sensors. Side brush one: three-beam, quick-detachable.
The central brush is bristly-petal, disassembled on both sides for cleaning from wound hair and wool. Behind the brush we see a comb for combing the hair wound on the brush. This design solution slightly untangles the brush, which further simplifies its cleaning.
Mopping nozzle holds up to 270 ml of water. Inside there is a pump for electronic adjustment of the liquid supply to the mopping pad. The mopping pad fastens on flypapers and with help of a groove.
In general, the build quality of the robot is high, there are no complaints.
The main characteristics of Dreame Bot D9 Pro, declared by the manufacturer:
- Battery Li-Ion 5200 mAh
- Suction power up to 4000 Pa
- Cleaning area up to 250 sq.m.
- Battery life up to 150 min
- Dust container capacity 570 ml
- Water tank capacity 270 ml
- Passage of obstacles up to 20 mm
- Dimensions 350*97 mm
The characteristics are completely identical to the Dreame Bot D9 Max and L10 Pro. We didn`t notice any changes.
Consider the functionality of Dreame Bot D9 Pro. The robot vacuum cleaner is controlled through the Mi Home app of the Xiaomi ecosystem. The application interface is in Russian, connecting the robot to a Wi-Fi network was easy.
On the main working panel, the robot vacuum cleaner builds a map of the room and automatically zones it into areas. Three modes of operation are displayed under the map. In the room mode, you can select the desired rooms, the sequence of their cleaning and the number of passes: 1 or 2. In automatic mode, the robot cleans the entire available area. In the “Zone” mode, you can set rectangular cleaning zones and the number of passes on the map.
In the map management section, we see that Dreame Bot D9 Pro can save multiple maps in memory. When working with the map, you can edit the boundaries of the room and name these rooms. In addition, restricted areas and virtual walls can be set on the map. And even separate restricted areas for the mode of wet cleaning.
Let’s go to the settings section. In the device settings, it first prompts you to adjust the volume of voice alerts and select their language. In addition, you can enable notifications to your smartphone, the function of automatically increasing power when driving on carpets, resuming cleaning after recharging at the base, setting the do not disturb mode and the frequency of reminders to rinse the mopping pad manually during cleaning.
Of the additional settings, it is proposed to adjust the suction power, the level of water supply to the mopping pad, as well as set up scheduled cleaning by selecting the time, days of the week, the desired rooms and cleaning parameters, view the cleaning log, track the status of consumables, switch to manual control mode and turn on the robot search by sound signal. Also, if necessary, you can change the name of the robot, share control with other users and update the firmware version to a more recent one.
In addition to all this, it is important to note that Dreame Bot D9 Pro supports voice control.
It is important to note here that in the settings, unfortunately, it is impossible to completely turn off the water supply when the tank is installed, and it is also impossible to flexibly adjust the cleaning parameters individually for each room. All other important functions are provided.
Let’s move on to the tests. First, let’s check the Dreame Bot D9 Pro navigation in the room with obstacles. First, the robot vacuum cleaner passes the perimeter of the room. It didn’t get stuck on the dryer, which is a plus. After passing the perimeter, the robot starts cleaning the entire available area with a snake, after which it again passes the perimeter and cleans with a snake in a perpendicular direction. He was able to sweep around the legs of the chair and the box, although the touch to the objects is not very soft and the robot moved them. However, the test passed successfully.
As for navigation within the house, the robot passes room by room, first along the perimeter, then in a snake. The cleaning speed is high, there are no uncleaned areas left. Navigation is good for this model!
Dreame Bot D9 Pro has a suction power of 4000 Pa. So, the robot vacuum cleaner was able to suck out debris from cracks up to 8 mm deep, like the previously released D9 Max. A 10 mm gap was too deep for him, although the older Dreame Bot L10 Pro was able to partially suck out debris from a 10 mm deep gap. It is not clear what is the reason, because constructively, robots are identical. Anyway, the robot in fact is very powerful!
The quality of dry cleaning on the laminate also satisfying. The robot vacuum cleaner was able to remove all debris from the floor, including wool and hair. Only the corners remained uncleaned, which is a problem for most round robots.
Some of the hair is wrapped around the side and center brushes, but most of the debris is still collected in the dust box. This test passed successfully!
The quality of carpet cleaning is high, the robot was able to collect all the debris, carefully cleaning the carpet with brushes, I have no complaints.
The quality of wiping off dirt is at the level of other robots in the Dreame line. The robot was able to wipe the dried dirt from the floor. A small area with a dirty streak was left along the baseboard, and minor streaks were found, as well as traces of dirt. Wet cleaning is not the Dreame Bot D9 Pro’s best feature; however, it will be enough to keep the house clean!
In addition, it is important to note that this robot vacuum cleaner can vacuum and mop the floor at the same time, although the water supply is not too strong!
Wet cleaning and carpets
As for wet cleaning in the area with carpets, Dreame Bot D9 Pro recognizes carpets, but does it with a slight delay, so it still drives onto the carpet with a mopping pad completely, after which the function works, and it moves off the carpet. So, it is better to protect carpets with separate restricted areas for the wet cleaning mode.
Passage of obstacles
Passage of obstacles in this model is good. The robot vacuum cleaner moves over 2 cm of the threshold easily, even with the wet nozzle installed. This is a plus.
Drive through dark surfaces
But Dreame Bot D9 Pro is afraid of black surfaces, recognizing them as height differences. This is important to consider.
And finally, we measure the noise level of the robot in different modes. At the minimum suction power, the noise level is about 60-62 dB, at medium power, the figure is in the range of 64 dB. In the intensive cleaning mode, the noise level reaches 66 dB, and in the Turbo mode, the peak value was 74.5 dB. Yes, this robot vacuum cleaner is noisy, but it is important to understand that the suction power is high, which is the reason for the increased noise level.
Dreame Bot D9 Pro was reviewed and tested in detail. On our rating system, it was able to score 73 out of 100 points, like the D9 Max, which is an excellent result for a mid-range robot vacuum cleaner. Both robots showed the same result in cleaning quality and similar functionality. Minor design changes did not particularly affect anything and, so was not considered in the evaluation algorithm.
The overall rating of all robot vacuum cleaners that passed the Robotobzor test you can find on the link below:
And here is my own opinion about Dreame Bot D9 Pro after testing. What I liked:
- Good navigation.
- High suction power.
- Simultaneous dry and wet cleaning.
- Good dry cleaning performance on both hard floors and carpets.
- All basic functionality in the application.
- Good passage of obstacles.
- High build quality.
Speaking about other comments, I would like to highlight not very high-quality wet cleaning and the fear of dark surfaces.
Well, if you are looking for a powerful robot vacuum cleaner with good navigation for dry cleaning and carpet cleaning, I recommend you considering this model or Dreame Bot D9 Max, if the price difference is significant for you.
