They have some lofty claims, and One is 3000Pa for suction. I don’t have a proper test for it yet, but we’ll find out how much airflow it got and how it compares to the top brands.
Dreame D9 review
D9 is DreameTech’s first LIDAR-based navigation robot With advanced features such as restricted areas and an invisible wall to keep it out of the restricted areas. There are not many robots In this price range It offers these two features. Navigation is a strong point and efficiency thanks to the LIDAR sensor. That was fine in the cleaning tests, but could be better – I’ll explain more in the Cleaning Performance section.

- LIDAR-based and affordable robotic vacuum cleaner
- Above average trash capacity (570ml)
- Long run time up to 150 minutes
- One of the least expensive options with the invisible wall and restricted areas combination
- Efficient Navigation
- Doubles as a robotic mop
- No map save feature
- Permits weren’t as clean as other premium brands like iRobot and Roborock
- Only two passes max, so it lacks accuracy
Introduction to Dreame D9 Robot Vacuum Cleaner
DreameTech first contacted me to review their product with the V10 a few months ago. Now, it’s the S9 smart robotic vacuum cleaner.
This robot has Roborock shades in its design, which is not surprising as it is a Xiaomi product.
It aims to compete with (the likes) of Roborock and 360 in the robot vacuum space between $300 and $400. The spec sheet is impressive: 3.0 LIDAR, smart navigation, up to 150 minutes runtime, 270ml water tank. But how do you adapt to a real-world scenario?
First, we’ll go over the features.
3.0 LDS + SLAM laser system
Dreame put the latest LDS sensor technology into the D9 – they called it the “New Laser System 3.0 LDS”.
It scans the room at 2080 points per second with high accuracy. Combine this technology with SLAM, and you get a highly efficient navigation robot capable of traversing through a maze of rooms without getting lost.
The advantage of LIDAR is that it requires no light – you can operate it in very dark conditions.
Two-in-one robot and vacuum cleaner
Like the Roborock S5 Max, the Dreame D9 can vacuum and mop, with the latter being the cheapest option.
I was so surprised Capacity 270 ml Since it has a flat design similar to the Roborock S6 Pure.
It’s a good idea to spread the right amount of water over the pillow to keep it damp but not wet (more on this in the wiping section).
The Dreame D9 only comes in one color (for now) – glossy (and matte) white. Above the LIDAR cover are three buttons – position, clean, and dock.
I don’t think you are going to use these buttons much since it has an app which I will talk about in another section.
Under the LIDAR there is a storage bin and brush cleaning tool. Like Roborock, Dreame’s trash is loaded from the top. The minus of the huge water tank enabled Dreame to use a larger litter box Capacity 570 ml.
It’s larger than the Roborock S4 Max and S5 Max (only 460ml), so it holds more dirt.
Beneath it, it has one side brush and one combo brush, again similar to the Roborock brush. The D9 has an interesting design with the rubber flaps in front of the brush and a rubber seal behind.
I’m not sure why Dreame put these plates on, I think it compromised cleaning performance because it impeded the transfer of debris directly into the brush.
Behind the brush there is a hole through which you can slip into the wiping reservoir/pad.
With LIDAR and SLAM, the D9 travels nearly as well as the Neato and Roborock. Cleaning the edges begins before moving towards the middle parts in straight lines.
I would say it has its quirks. The first is the wider overlap when it turns around. It shouldn’t be a problem with regular cleanings because it should only deal with dust and hair.
By default, the D9 will only pan twice, and it has no option to go further than two. I hope Dreame will increase this to three apps in the future to compete with the likes of Roborock.
Invisible wall, restricted areas, and no-entry areas
Dreame is one of the least expensive options I’ve tested, with access to an invisible wall, restricted areas, and restricted areas.
I think these features are essential in any robotic vacuum. Provides you a tool to prevent the bot from going into restricted areas. So it eliminates the need to physically block the bot. Believe me. Every home has these areas.
An invisible wall is a line that prevents the robot from crossing it. You can set straight or diagonal lines – there are many options about which areas to block.
The blocked and unerased area are similar in that they block a square or rectangular area.
Does Dreame D9 remove furniture
D9 is excellent at avoiding objects, even in the middle of a room. For testing, I placed an alcohol dispenser and a smaller alcohol bottle to see how much to push the robot.
I barely moved the alcohol dispenser and avoided it on subsequent passes. And while he was pushing the alcohol bottle, it wasn’t hard to fall.
This means that the D9 will slow down and not hit the furniture as hard.
Dreame D9 is compatible with the Xiaomi Home app. I will run through the features.
The D9 app has a live map where you can see, in real time, where the bot is located on the map, the size of the area, the battery status, and more.
Unfortunately, it does not have any possibility to save the map. So it is suitable for single level homes. Those who live in a multi-storey dwelling may have to choose the Roborock S4 Max unless you are okay with the bot remapping and have to adjust the invisible wall or restricted areas when cleaning another floor level.
Users can assign names to each section of the map, but there is no custom naming feature. You only choose from a pre-selected set of names that the app provides.
Selective room cleaning
There is also the option to mark the areas to be cleaned. This is done by clicking on an area on the map (only after setting the sections). You can adjust the order in which these rooms are cleaned and the corresponding power and water levels (if a mop is connected).
The D9 is the cheapest robot vacuum so far I’ve tested with this feature.
It has a carpet boost feature, where the robot automatically increases suction when it detects carpet. I like this feature because it helps to extend the uptime to the maximum without careful management.
So you can leave it on a low setting and rely on the booster rug to only increase the suction on the carpet.
Invisible wall, restricted areas, and no-entry areas
I have already touched on these features above. But I will quickly review what each function does. The invisible wall are straight lines that you can adjust vertically, horizontally and diagonally to block out specific areas you don’t want the robot to enter.
No-entry zones and mop zones are square and rectangular zones that are off-limits to the robot. These features, I believe, are essential features that all robot vacuums should have.
Dreame also adds unlimited scheduling to D9. This means that you can schedule an unlimited number of rides per day. It’s something that isn’t available with mid-level Roomba options like the 980. It gives users more options when powering the bot, with the corresponding power mode to suit the time.
So you can ask the bot to work at night at any of the lower settings, and it won’t disable most activities.
Recharge and resume
Users can also turn on the resume feature, which instructs the bot to recommend cleaning after a recharge if it hasn’t finished the task beforehand.
Power and water settings
There are four power settings and three water level settings on the Dreame D9. The water level setting will only appear when the water tank is connected.
Shows you past cleaning cycles along with corresponding maps. This tab also provides users with an overview of total usage numbers – hours, area, and total runs.
This tab provides heads for users when changing the filter, side brush, and main brush. But don’t rely solely on this. Always check these parts regularly to see if they need cleaning or replacement.
Some features I wish the D9 had
Unfortunately, Dreame omitted some features which I feel they should add. The obvious thing is the inability to save maps. You cannot save maps with the D9 app. If you are taking the bot to another level, the map must be reset.
There are several drawbacks to this. The first is the need to frequently create unbreakable walls and no-go areas if you constantly need to move different floors.
Next is the inability to name the rooms.
While these are all downsides, it is an easy fix as it is a software issue.
Finally, he can only make two passes.
How much power does Dreame D9 have?
Dreame claims the D9 has up to 3000Pa of suction. For now, I’m still trying to figure out how to measure suction, so I can’t confirm that.
To measure airflow, I use the main brush’s anemometer.
Below are the results for the Dreame D9 at its four power settings.
- calm: 8.8 CFM
- Basic: 11.05 cubic feet per minute
- strong: 13.39 cubic feet per minute
- Turbo: 15.97 cubic feet per minute
The airflow results are good but not excellent, and the results of the deep cleaning confirm the airflow levels have increased by an average of 65.55% after two runs.
Airflow is a factor for deep cleaning, but other aspects come into play as well, such as the brush roller’s design and seal.
Dreame D9 has undergone a series of tests to check how well it catches various debris and tried it on things like Quaker oats, coffee grounds, quinoa, pet litter, sand, hair, etc.
First, here are the scores.
- Total: 87.01
- Solid ground: 95.9%
- Carpet (surface): 95.92%
- deep cleaning: 65.55% (Second round: 74.2%)
- Sand on the hard floor: 90.7% (second range: 98.9%)
The scores above are from a single two-track round, which is the maximum that the Dreame D9 offers. I did a second two-track run of sand on the hard floor test and the deep clean test (results in parentheses).
Although with nearly identical results on hard floor and carpet, I feel the D9 is Best suited for carpet cleaning.
The lack of a third pass and wider turns are detrimental to her ability to clean. When I say more broadly, it means that there is almost no overlap between the classes. So, if debris is in between the overlay, the robot will probably miss it.
hard floor results
- Quaker Oats: 97.2%
- Cafe floors: 96.6%
- Quinoa: 94.4%
- pet litter: 95.4%
The results were good but lagging behind other brands like Roborock and iRobot.
Despite above-average airflow, the D9 didn’t pick up debris cleanly. There was visible debris after the initial pass.
I suspect the culprit is the culprit, so I use masking tape to get it out of the way. But the results remained the same.
The lack of interference and the operation of only two passes also harm the cleaning ability of this surface.
Another concern during cleaning tests was a scattering problem with the side brush. It spun faster than I expected, and the debris spread to a wider area.
Sand test on hard floor
Sand is one of the most difficult elements to clean on hard floors. To check how well the D9 picks up, I sprinkled 50 grams into the test area.
I picked up 90.7% after the first two passes A noticeable patch is left. So I took a second round, and the score went up to A More respectful 98.9%.
There were traces of sand left, so it’s not something I would recommend for regularly cleaning sand.
I scattered leftover coffee in one corner of the room to see how much the D9 was picking up.
This is a before and after picture.
D9 did a pretty decent job capturing most of it after two passes. However, the circular frame hindered its access and did not reach every crumb.
I tested the DreameTech D9 on a low and medium pile carpet using the same debris set.
Eye testing showed that the D9 performed better on carpet than on hard surfaces. There was minimal scattering of the side brush as it had more friction. The aisles were cleaner, but it would struggle to pick up a large amount of fine debris such as ground coffee.
- Quaker Oats: 98.6%
- Cafe floors: 86.4%
- Quinoa: 100%
- pet litter: 100%
D9 got 100% from quinoa and pet litter and was suffering the most from ground coffee. The airflow isn’t the issue here, but the agitation and possibly the seal behind the brush.
- Quaker Oats: 98%
- Cafe floors: 84.4%
- Quinoa: 100%
- pet litter: 100%
Mid-stack results reflect the low lint test; It also contains 100% quinoa and pet waste, while only 84.4% ground coffee.
deep cleaning test
For the deep cleaning test, I rubbed 100g of fine sand on a medium pile rug.
The D9 was shot with an average 65.55% after the first two passes.
I did my second run and the result improvement to 74.2% – Good result, but it does not replace the vertical or stick vacuum cleaner to clean the existing dirt.
hair wrap test
To check how tangle-resistant the D9 is, I tested it on one gram of human hair five and seven inches in diameter, then weighed the contents of the box and the strands around the brush.
The results for both five and seven inch threads are identical.
- 5 inch test: 0.4g inside the container (40%) and 0.6g around the brush
- 7 inch test: 0.4g inside the container (40%) and 0.6g around the brush
Part of the maintenance should include detangling the hair. The D9’s anti-tangle system isn’t enough to keep long strands of hair out of the brush.
The DreameTech D9 is one of the least expensive options I’ve tested with an electronic water tank. It looks small with a flat design, but it has a capacity of 270ml. But you cannot use any cleaners or cleaners as they can damage the rubber and electronic components inside.
I’ve tried it on dried red wine stains (I left it on overnight), and the results were similar to the more expensive S5 Max.
In this experiment, I used the highest setting for the water flow. I used the middle setting during the first pass, but it didn’t saturate the pad enough.
But after going to the maximum flow level, I succeeded in removing the stain without leaving much residue.
It left tire marks at first, but they quickly dissipated because the floor was only wet. If scanning is a benchmark for you, the DreameTech D9 should be on your shortlist.
How noisy is the Dreame D9?
I used the audio meter to check the noise levels on the D9, and here are the results.
- calm: 59.1 dB
- Basic: 60.5 dB
- strong: 62.8 dB
- Turbo: 64.7 dB
The results were similar to those of the Roborock S5 Max, also under 65 dB. At the lower settings, it’s quiet enough to use without interrupting the conversation. But the lowest setting is not usable apart from cleaning dust, but ideal for wiping.
How long does the Dreame D9 last?
D9 . will turn on For up to 150 minutes at its lowest level. Uptime shouldn’t be an issue with the D9 since it’s recharging and resuming. So even if you haven’t finished cleaning the area, it will resume cleaning after recharging in the location you left earlier.
What comes in the box?
You will get these items from the box.
- Dreame D9 Robot Vacuum Cleaner
- Charging station and plug
- Manual and quick start guide
- Water tank plus microfiber pad
Availability of spare parts
Since the D9 is a new product, there isn’t much in terms of parts availability. Hopefully, components such as the side brush, main brush and filter will be available.
Maintenance is critical to the longevity of any robotic vacuum cleaner. I will enumerate the components that you should clean and replace periodically.
- Basic brush: This part takes the most beating because it is responsible for cleaning up debris and hair. Check this ingredient regularly for hair and dust buildup.
- Side brush: Check this section for any hair wrapping on the base. The D9 version does not have a threaded screw, so it is easy to detach.
- Dustbin: Vacuum the contents after each cleaning cycle to prevent dust mites from breeding indoors.
- filter: Dreame says the HEPA filter is washable. My recommendation is to tap it on a hard surface to get any debris stuck on it out. Use a handheld tool with a brush attachment as part of its maintenance.
- Sensors: Wipe the drip sensors underneath with a clean microfiber towel.
- Wheels: Use a clean towel to wipe the side wheels and wheels.

Does the Dreame D9 provide excellent value?
Dreame offers a feature set that makes it a compelling choice for people who are looking for an affordable robot vacuum.
It’s the least expensive I’ve tested with an electronic water tank, no-go zones, no-no zones, and an invisible wall.
This robot will wipe something more expensive, like Roborock. But they don’t sweep the floors either.
Its quirks with the navigation and cleaning dynamics hamper it with the latter, but it should hold up well for everyday cleaning tasks.
Verdict: Great for mopping, average with sweeping floors
After spending several days testing this bot, the results were somewhat disappointing. I expected more with the navigation and cleaning performance, but it wasn’t as good as brands like Roborock and Roomba.
Clearances weren’t clean, and while the navigation was efficient, it lacked the precision I was looking for in a robotic vacuum cleaner.
The wipe feature was a pleasant surprise, but DreameTech will have to improve with the navigation and cleaning dynamics if they are to seriously compete with home brands.
Mid-level robot vacuum cleaner with advanced features
- Mobility – 94%
- Surface cleaning – 94.17%
- deep cleaning – 65.55%
- Quality – 95%
- Design – 94%
- Values - 97%
- TOTAL AVERAGE: 90%
I had high hopes in Dreame, and I achieved a degree with a survey job. However, it stunned the cleaning tests. The passes weren’t as clean as I would have liked them to be, and the navigational quirks hampered them even more. But it is difficult to determine the price and features that it brings to the table.
