Dreame D9 Max vs Roborock Q7 Max: they are vacuum fortresses from two renowned Chinese brands, both reputed for storming the market with bots brimming with features – and these models are no different. These bots are all designed to clean your living space with minimal intervention on your part. They can map out your home, navigate for cleaning, and return to their clean bases when the battery is low.

However, the Roborock Q7 Max has better cleaning performance, fights tangles better (thanks to its bristle-free roller), and offers more features on the app. On the other hand, the Dreame D9 Max has a larger dustbin and operates quieter.

Dreame D9 Max Vs Roborock Q7 Max: Differences

The Dreame D9 Max wins 4-2 against the Roborock Q7 Max. Delve into my detailed comparison of these two powerhouses for more insights!

Cleaning Performance

Winner: Roborock Q7 Max

Hard Floor

Dreame D9 MaxRoborock Q7 Max
≈ 94%≈ 97%

Although the Q7 Max and the D9 yielded almost identical results on my hard floor, the former Max was better suited for cleaning this type of surface with a very high score. As for the D9, it didn’t pick up debris cleanly, leaving visible remnants behind.

Carpet

Dreame D9 MaxRoborock Q7 Max
Low-pile Carpet≈ 92%≈ 94%
High-pile Carpet≈ 94%≈ 95%

Both of these two bots also performed very well on my two types of carpets, with among the best results. Of course, they are far from replacing a stick or upright vacuum for cleaning embedded dirt.

Hair

Dreame D9 MaxRoborock Q7 Max
5-inch Strands≈ 67%≈ 87%
10-inch Strands≈ 48%≈ 61%

To check how well they can pick up hair and resist tangles, I tested them on a combination of five and ten-inch hair, and the Q7 Max took the lead again. It gathered a more significant amount of hair and, notably, demonstrated superior tangle resistance thanks to its lack of bristles.

Weight8.38 lbs8.38 lbs

The D9 Max and the Q7 Max are both vacuum-and-mop robots that are similar in round-shaped frame and weight, with the former being the more cost-effective option. Both have a LiDAR tower, making them a bit taller than these camera-based bots from iRobot, for example, but they could still navigate under my TV cabinet, coffee table, and sofa. They also come with compact charging docks instead of bulky self-cleaning bases, so they conserve space in your living area.

Extractor & Side Brush

Both are equipped with a single brush roll and a single side brush beneath them, but there’s a distinct difference in their main brush rollers.

The Q7 Max employs a bristle-less rubber roller to avoid hair tangling, while the D9 Max incorporates a combination of rubber fins and bristles, which are prone to tangle with hair. But this is hardly a concern since both can be taken off easily for convenient cleaning of entangled hair and fur. What’s more, the D9 Max includes a cleaning brush featuring a bladed end, specifically designed to tackle stuck debris and tangled hair in its roller.

Speaking of the side brushes, the Q7 Max has a single all-rubber brush, surpassing the bristled one on the D9 Max in terms of durability. During my testing, they did a great job of directing dust and dirt into the main cleaning path instead of causing them to scatter in various directions.

Navigation

Both the D9 Max and Q7 Max rely on LIDAR technology to map out your living space and navigate efficiently. That means they use laser beams to scan their surroundings quickly and accurately (even in pitch-black conditions), contrasting with built-in cameras that necessitate sufficient light and often require multiple runs.

Unfortunately,  D9 Max bypasses some nifty features that it should have, and the obvious one is the lack of a map-saving function. Yes, while the Q7 Max can remember four maps, the D9 Max can save nothing. This means that if you transport the D9 Max to another floor, the map needs to be recreated – This is a big con for those who live in multi-level apartments.

These bots are not very good at avoiding obstacles. From my testing, they touched faux pet waste instead of completely avoiding it, like the Roomba J7+ or Roborock S7 MaxV. This might be acceptable for regular obstacles, but it poses a real issue if it were to come into contact with dog waste, wouldn’t you agree?

Battery Life

Dreame D9 MaxRoborock Q7 Max
Battery Life≈ 68-143  mins≈ 91-183 mins
Charging Time≈ 212 mins≈ 198 mins

Each model operates on a large 5200 mAh battery, boasting impressive working life between charges. The presumption of them having smaller batteries should not be a concern, thanks to their recharge and resume feature. This means they autonomously navigate back to the charging base after a cleaning cycle or upon battery depletion, recharge fully, and then return to the last uncleaned spot to resume cleaning.

Control

Winner: Roborock Q7 Max

Manual Control

The control panel atop both is minimalist, with just a few physical buttons. To access their full functionality, you need to download the corresponding app, but if you just want something like starting a cleaning trip, these buttons have you covered. Both have a “Power” button to give you a quick way to start or end a cleaning cycle without your phone and a “Home” button to navigate the bot to its charging base. The Q7 features a “Cleaning Spot” button for cleaning a specified zone before automatic deactivation.

App Connectivity

To unleash all the capabilities of these smart bots, you need to connect them to your phone via the app. The D9 Max works with the Xiaomi Home, whereas the Q7 Max is compatible with the Roborock app. Both apps are free to download and are compatible with both iOS and Android devices.

Both apps offer a live map where you can check where your robot is in real time. The Roborock can even show the map of your living space in 3D, but I didn’t really see it as a must-have feature.

Both apps give you some options to virtually block the D9 Max and Q7 Max from going into some off-limit zones in your house, so you don’t need to block them physically. They include no-go zones and invisible walls with the same function. They have the option to set no-mop zones as well to prevent these hybrid robots from unwantedly dampening your carpeted areas, which is especially necessary since they both lack a mop-lifting system.

Both apps also have the option to clean specific areas instead of the entire house after you are done with setting partitions. The Xiaomi app only enables you to assign preset names to each room rather than custom ones like Roborock. Once all your rooms have their own names, you can have the D9 or Q7 set to clean your kitchen and bypass the rest, for example. You can even do this with your powerful voice if you have Google Assistant or Amazon Alexa.

Both apps also allow you to schedule cleaning and alert you when the side brush, main brush, and filter necessitate change, but this prompt should not be your only reminder. Regular inspection of these parts is still highly recommended to determine if cleaning or replacement is needed.

Cleaning & Maintenance 

Winner: Tie

Talking about the dust bin, the D9’s bin has a capacity of 0.57 liters, larger than the 0.4-liter one the Q7 carries, so the latter can hold more dirt. In return, the water container on the D9 Max has a capacity of 0.27 liters, smaller than the Q7’s 0.35-liter tank. This factor should be taken into account because both don’t come with a self-cleaning base, meaning you need to empty their bins and refill their tanks manually. If you are interested in the clean base, it comes with the Roborock Q7 Max+.

The D9 Max and the Q7 Max incorporate HEPA and E11 filters, respectively, both proficient in filtering out 0.3-micron dust particles and preventing secondary pollution.  By the way, they are washable, but they need to be completely dried before being used again.

Noise

Working≈ 56-68 dB≈ 59-75 dB
Self-EmptyingNoneNone

I also employed a sound meter to assess their noise levels and determined that, in lower settings, they operate quietly enough not to interfere with nearby conversations. But when increased to their maximum setting, they could disturb those sensitive to noise or, at the very least, startle your furry friend. By the way, both the D9 Max and Q7 Max have four suction settings.

Mopping Ability

As 2-in-1 robots, the D9 Max and Q7 Max can vacuum and mop at once. So if you are too busy to clean your floors every day, they should be on your wishlist. But spoiler alert: Their mopping ability is good but not great enough for you to say goodbye to your real mop.

First off, they are among the cheapest hybrid robots with electronic water tanks I’ve tested. All it takes to set up the mop unit on both are filling their water tanks and setting the water flow via the corresponding app, and they are good to go. Be mindful not to use any cleaners or detergents since that’s the shortcut to kissing your robot goodbye, or at least that’s what the manufacturers advise. The mop pad can be washed and reused repeatedly.

But due to the lack of a mopping sonic vibration system, they have proven to be less effective than more advanced hybrids in dealing with stubborn stains, such as dried BBQ sauce. But for lighter things like pet footprints, a quick mop with them would do the trick. What’s more, given they don’t have liftable mop units, it is essential to demarcate no-mop zones through the app to protect carpeted areas.
