Dreame D9 Max vs Roborock S7 MaxV - Where are the differences?
Where are the differences?
The D9 Max robot vacuum cleaner differs a few points from the Roborock S7 MaxV. Let's go into the differences in detail.
release date (release)
For the comparison of the two vacuum cleaner robots it is of course the age of the models interesting. After all, every year there is new technology. The products were introduced in two consecutive years. The Dreame D9 Max was introduced in the year 2021. Thus the Roborock S7 MaxV is newer from the year 2022.
Which robot vacuum cleaner is falcher?
When it comes to the technical specifications of a robot vacuum cleaner, height is especially important. Robot vacuums with a lower height can clean better under furniture, as they can better drive under cabinets or even the couch. The Dreame D9 Max and the Roborock S7 MaxV have an identical device height of 9.6 cm and thus do not differ in the point of height.
Vacuum power comparison
The suction power depends on the maximum suction force. This is specified in Pascal (short: pa). In this point there is a difference in the comparison Dreame D9 Max vs Roborock S7 MaxV. The Roborock S7 MaxV offers higher suction power in comparison with 5100 pa. This makes it the better vacuum robot in this point. However, the suction power is lower depending on the suction level. The maximum suction power is always indicated. With the Dreame D9 Max you get a suction power of 4000 pa.
Does the battery performance differ?
The Dreame D9 Max has a lower battery life than 2,5 hours with the Roborock S7 MaxV in comparison. The longer battery life means the Roborock S7 MaxV has to return to the charging station less often, allowing it to clean longer at a stretch. This also allows the model to vacuum more quad meters at a time.
What can the apps do?
Numerous vacuum robots can now be programmed and also controlled via apps. Adjustable are, for example, premises, maps as well as running times. Some suction robots can then be started conveniently on the go. For both vacuum robots, the Dreame D9 Max and the Roborock S7 MaxV, there is an App. The app of the Dreame D9 Max is . Both vacuum robots allow zone cleaning via the app. Thus, only certain areas are cleaned without having to set up additional obstacles.
Voice control
Many robotic vacuum cleaners can now be controlled by voice assistants, allowing for convenient operation.
The two vacuum robots can be operated with Amazon's Alexa voice control. Neither device can be controlled using Google's voice assistant (Google Assistant).
Is there a wipe function?
In addition to the pure suction function, some vacuum robots also have an integrated wiping function. This combines two devices in one and the cleaning performance is significantly increased - not to mention the time saved. The models are then called suction-wiping robots.
The both vacuum robots can feature an integrated wiping function and are thus both wiping robots. The Roborock S7 MaxV* offers as a special feature a vibrating wiping plate. Through this, scrubbing is realized, with which the dirt is better removed and a better cleaning result is produced. The pure wiping function without vibration has not shown good cleaning result in most suction-wiping robots. Basically, the mop is just dragged across the floor.
For a carpet, the Roborock S7 MaxV automatically raises the wiper and only vacuums. This offers the advantage that the carpets do not have to be cleared away. The Dreame D9 Max cannot do this.
The water tank of the Dreame D9 Max has a larger capacity with 270 ml than that of the Roborock S7 MaxV with only 200 ml. This is an advantage for Dreame D9 Max.
Which vacuum motor has the larger collection tank?
Since the collection bin of the Dreame D9 Max with 570 ml has a larger capacity compared to the Roborock S7 MaxV, it can hold more dirt. Thus, the dust chamber of the D9 Max needs to be emptied less frequently. The Roborock S7 MaxV has a dust bin with 400 ml capacity.
