Roborock S7 MaxV Ultra: Review & Station Test

Roborock S7 MaxV Ultra Roborock

Hey guys, welcome to RobotObzor! As I promised, in this video I’ll go over and test the Ultra station that goes with Roborock S7 MaxV. This station comes with the Roborock S7 MaxV Ultra vacuum cleaner. Later I’ll mention what it’s capable of, how well it does its job, and if it’s really worth its money. Keeping in mind it’s price, or rather the difference between Roborock S7 and S7 MaxV is about $600 at the time of the video, I have high expectations of this robot. Now, let’s get started!

A brief review of the robot vacuum

To start, I’ll briefly talk about the Roborock S7 MaxV vacuum itself, which has its own video on our channel:

By design and functionality this is definitely one of the best if not the best robot vacuums of 2022. According to the tests, it’s well oriented, and perfectly recognizes objects like in light or dark areas, thanks to special LED-lighting under the camera. The quality of the vacuuming and mopping is good. I’ll also note that the robot can lift the cloth when driving into carpets, which allets it effectively mop and vacuum, and leave the carpets dry and clean. Additionally, the robot is very powerful and can go over 2 cm (.78 Inch) baseboards. The only concern I have is with the pitch dark flooring, which to be fair most robots can’t drive on either. Otherwise, everything’s on the same level as other premium robots, if not better.

Station overview

Now let’s look at the station. It comes in black, and is very sleek. At least the design looks like its worth its money. The plastic is good, with a clean matte finish. It’s dimensions measure 422*504*420 mm (16.6 x 19.8 x 16.5) .

Roborock S7 MaxV Ultra Station

The station came in a box like this, separately from the robot. But Roborock has said that the new batch will have the station included with the vacuum. Aside from the vacuum, I also got an extra trash bag and an instruction manual.

On top of the station are three little compartments: a tank with dirty water, a tank with clean water, and a see-through lid, under which is a trash bag for collecting the dirt that the vacuum hs picked up. The clean water tank holds 3 liters (.79 gallons), the dirty water tank holds 2.5 liters (.66 gallons), and the bag holds up to 2.5 liters (.66 gallons) of dirt.


Spoiler alert! By default, the tanks can’t connect to the water and sewage pipes to better automate the station and further simplify itself. Luckily, I found info on the internet that something like this is already a reality in the Chinese market, namely a conjoined dirty and clean water module that can connect to your utilities. This is very cool! Now let’s hope that this makes it into the western market!

Let’s keep going! The platform is equipped with a channel for moving dirt. The self-cleaning process goes through the central brush unit, just like the previous Roborock S7 and Q7 Max.

The charging ports are located on the end, the charging plugs for the robot are mounted on the front of the bumper. This sadly makes it so that the S7 and Q7 Max aren’t compatible with this station.

Inside the station is a fluffy roller in charge of cleaning the cloth at the station. This, by the way, can be replaced if needed.

Clean water goes to the robot’s cloth and the roller scrubs off anything stuck to the cloth. The dirty water passes through a coarse filter which you can take off and wash!

Unfortunately you can’t remove the platform, just in case you were thinking of washing it. The manufacturer recommends wiping it with a damp cloth.

But the station can refill the robot’s clean water tank. This is a cool feature, thanks to which Roborock S7 MaxV can clean not only with a clean cloth, but also supply it with water while its cleaning, getting the perfect amount of water.

According to the manufacturer, the robot that comes with the Ultra station has good mopping quality on areas up to 300 sq. m (985 sq.f). I think that by adding a module to connect to the utilities, the max area will increase even more and you could consider using Roborock S7 MaxV Ultra at a larger level, from your home to a business, for example an office. It would steal the janitor’s job! 🙂

Well, it’s also important to note that the station doesn’t have a module for drying the cloth, although the app has an option to do so, even having the amount of time you’d like to dry it for. Once again, the internet reveals that this option is sold on the Chinese market.

By the way, the last known option is a silver plate, which is apparently installed in the clean water tank to disinfect it.

It’s worth pointing out that after the cleaning cycle, the robot first cleans itself by unloading the dirt, then rinses its cloth by reversing into the station, and finally driving out and driving in forward to charge.

The last thing I’ll note is that the back of the station has a compartment for putting in your extra cord.

Let’s move on!

  • Battery Li-Ion 5200 mA*h.
  • Suction power 5100 Pa.
  • Battery life: 180 mins.
  • Cleaning area 300 sq.m (984 sq.f).

  • Trash bag: 2,5 L (.66 Gallons).
  • Size: 422*504*420 mm (16.6x 19.8x 16.5 Inches).


Roborock S7 MaxV’s functions have also been discussed in a separate review. Briefly, you can select the desired zones and rooms for cleaning, choose the amount of passes by the robot, adjust the suction power and the amount of water the wipe gets, and even adjust the cleaning parameters individually for each room. You can also set virtual walls and no-go zones on the map, and even separate no-go zones for the wet cleaning mode (No-Mop Zones). I’ll also add that Roborock S7 MaxV Ultra can save several maps, you can set up recognition of objects on the floor and how the robot behaves when it gets on carpets. It can lift the wipe on them, gently bypass them, or drive over the carpet with the wipe down. All in all, there are many adjustments and they allow you to flexibly individualize each room.

But of course it’s much more important that you know Ultra station’s functions. So, you can choose one of three cloth washing modes. Basically, from eco water use to deep cleaning. You can also set the frequency at which the wipe will be washed. Roborock took their own approach to this feature. Either the robot rinses the cloth after each room, taking into account its area and the possibility of washing it multiple times from one room, or after a given amount of time (from 10 to 50 minutes).

Speaking of self-cleaning, you can turn off the trash dumping function in the station if needed. You can also choose one of four self-cleaning modes.

And here’s the actual setting for drying the wipe, which only works if you have attached the optional dryer module. You can turn on the autodying and set how long you want it to dry for.

Quickly, let me show you the strange, but nonetheless hilarious Cupid mode, which when activated, will make the robot search for others and kiss them. Absolutely hilarious)

Lastly, here’s function showing you the water and filter status in the info side of the settings.


Cleaning time

Finally, let’s get to the tests. First we’ll check the vacuum’s cleaning time within the house, rinsing the cloth every 10 minutes. For comparison, I’ll bring out the Roborock S7 MaxV complete with generic charging base.

Under normal conditions, it took the robot 50 minutes to clean 50 square meters (164 ft) of the area. With the wipe rinse enabled, Roborock S7 MaxV returned to the base 4 times within one cleaning cycle, then returned to clean from where it left. Interestingly, the time stops during the return to the station or during the rinse cycle itself. The report shows the same 50 minutes. But if you compare the time displayed at the top of the screen, you can see that 70 total minutes have passed.

Self-cleaning quality

The following test will show S7 MaxV Ultra’s self-cleaning quality. For this, the floor was scattered with different dirt. The robot collected it perfectly.

We can see that all of the dirt is in the bin, and that the brushes didn’t wrap any hair on themselves. We start the self-cleaning process and wait. We see that some dirt is left in the container. Re-run the self-cleaning process and see that the station can’t suck anything else out. Remove the brush and see if there’s anything stuck inside. The suction duct is clean.

As a result, the problems that we saw with the Roborock S7 Plus with self-cleaning stayed. The self-cleaning quality isn’t ideal. If you’re already using this base, please let us know how it works for you in the comments.

Cloth rinsing quality

Well, in a similar test, let’s check how well it rinses the cloth. I smeared a little dirt on the floor beforehand. The floor’s clean, and here’s how the cloth looks. We can see that it took in all of the dirt.

Let’s rinse the wipe, and wait. We can see that the wipe is much cleaner. Take it out and check under the stream of clean water. Some dirt stayed, but it’s not terribly much. I’ll say from experience that it did good, not worse than others, so I’ve no complaints.

Here I’ll add that just one cycle in deep cleaning mode uses 250 ml (8.5 Oz.) of water. So in my 70 sq.m (230 Sq.F) apartment, it’s enough for 2 full cycles. This again, in deep cleaning mode and you need to consider the flow of water to refill the tank in the robot. The robot-vacuum itself is set to give out max water supply when cleaning.

Personal Opinion

Roborock S7 MaxV Ultra was fully reviewed and tested. I’ve already expressed my opinion about the robot, it’s almost perfect, and the only downsides are present in most other robots.

Now, I’ll share my opinion about the station. Here’s what I liked:

  1. Stylish design.
  2. Designed to clean the cloth and container.
  3. Good cloth rinsing quality.
  4. Flexible rinse interval settings.
  5. Automatic water pumping to the container.
  6. Optional module for connecting to the utilities.
  7. Well, in case anyone was wondering, the tanks are sealed. The dirty water’s smell doesn’t spread. The funky smell doesn’t spread around the room. At least I left dirty water in the tank for 3 days and didn’t smell anything coming from the station. But it’s best not to abuse this.

As for the downsides, I’d like to point out the following:

  1. The self-cleaning isn’t perfect.
  2. The cloth drying option is sold separately.
  3. The platform in which the vacuum gets rinsed isn’t detachable.
  4. Very expensive. I mean it doesn’t come separately, but I’m comparing it with Roborock S7 MaxV и Roborock S7 MaxV Ultra here.

Overall, the Roborock S7 MaxV Ultra has left a mostly positive first impression and can actually be considered a gear for automatic cleaning. It combines a large number of functions, advanced technology and intelligent design solutions that simplify the maintenance of the robot and increase the ease of use, to put it in technical terms. It’s expensive, but it’s worth it! You can’t call it perfect yet, just like many others. But Roborock is already very close to a perfect model.

On this note, I’d like to end the review. If you have any question left, make sure to ask them in the comments below. Have fun shopping, bye!
