There is no point in talking about a design that cannot be more classic than the Dreame D9. Like many other robot vacuums, it has a round shape and a shiny white plastic dress. A smart choice, as fingerprints or dust on the lid will stand out less than on a black model.
There are exactly three buttons on the hood: one to manually return the robot to the base, another to pause and restart it, and the last one, finally, to start the Spot Clean mode (the robot will vacuum a certain area).
Dreame D9 is equipped with a laser rangefinder, which allows it to determine its location in space and thus the best way around the obstacles encountered in its path.
In addition, the manufacturer has equipped its robot with a washing function. As such, it comes with a microfiber mop and a 0.4L water tank that attaches to the bottom of the device. Please note, strictly speaking, this is not a floor scrubber like the Yeedi Mop Station.
Indeed, the D9 mop is not capable of removing stubborn stains. Here, rather, a function aimed at giving the floor freshness between two “real” sinks. However, we appreciate that the D9 can mop the floor while vacuuming, and the user doesn’t have to remove the dust box to replace it with a water tray.
Application and connection
There are no changes in the app between our Dreame Bot L10 Pro test and the D9 test. As we have already said, you should not use the Dreame app, but the Xiaomi app, which is called Xiaomi Home. Pairing only takes a few seconds, just follow the instructions and you’re done.
Once in the main interface, numerous functions are available. You can select a cleaning mode (quiet, standard, strong and turbo), a water flow setting (low, medium and high) or even a restricted cleaning zone. This last feature allows you to demarcate areas so that the vacuum cleaner avoids them while cleaning, as well as create virtual walls – handy when you’re scheduling cleaning while away from home.
There is also a map management component which, as its name suggests, gives you access to various saved maps since the D9 can save multiple. Thus, if necessary, it can be used on several floors. The live display is also pretty well presented and you can easily tell which room the robot is in.
By entering the settings, the user gets access to the cleaning history, programming of cleaning sessions or the remaining life of consumables (filter, brushes).
The waste collector has the form of a cassette and slides under the casing. The capacity of this reservoir (0.5 l) is large enough so that it does not have to be emptied too often. However, emptying is not very hygienic and it is not uncommon for dust to fly out when the cassette is opened. We recommend submerging the latter to the bottom of the bin when emptying to avoid blowing off the dust.
This collector is accompanied by a HEPA type filter. It will just be necessary to detach it from the tray in order to gain access to it and wipe off the dust. We recommend that you remove it after every cleaning to prevent too much dust from accumulating on it. Of the 20g of cocoa we sucked up with the Vacuum D9 to test its filtration efficiency, 1.4g got stuck in the filter. This may seem small, but it can ultimately reduce suction performance.
Turning the robot on its back reveals a side brush (just pull it out to remove and clean) in addition to the rubber and nylon bristle main brush. Instead, we would prefer a simple blade made of soft plastic so that the hair is less tangled in it, imitating, for example, iRobot robots.
At the same time, this brush is very easy to remove from the device: just lift the grid covering it. The small brush included with the vacuum cleaner is used to remove debris tangled in the main brush.
Like a fish in water, the Dreame Vacuum D9 moves carelessly through our lab, despite the traps we have deliberately placed in its path.
On startup, the device pauses for a few seconds to analyze its environment before starting to work. He then starts following the walls and then attacks the center of the lab.
The Vacuum D9 zigzags brilliantly avoiding the legs of a table in the middle of the room and, conversely, passes over the legs of chairs with no problem. At the end of the cleaning cycle, we find some sawdust, which we have deliberately scattered in our laboratory along the baseboard and also under the curtains. Nothing terrible though. Most robots fail to extract material from behind curtains, which they usually mistake for a wall.
The Dreame D9 made a tour of our lab in just 10 minutes. We found 86% of the sawdust scattered on the ground in its picker, which suggests that navigation was efficient and fast.
Excellent suction performance.
Navigation with small bows.
Extra quiet vacuum cleaner.
How does assessment work?
With the D9, Dreame confirms its reputation and once again signs a contract with an excellent robot vacuum cleaner. The suction performance is there and, above all, it orients itself perfectly, avoids obstacles and manages military navigation. At the same time, the D9 turned out to be quiet and hardy, so it did not leave much to be desired.
