Negatives:
1) It cannot clean corners and due to its bulk it cannot fit under low furniture like sofas, or in narrow spaces. It is therefore necessary to use an additional device to clean these areas.
2) It needs thorough cleaning after EVERY use. That is, it adds to the amount of work you have to do. (I rinsed the bins with water and already after a week of use, it smells strongly. It is necessary to use a cleaner to wash the containers each time.) - This was known before its purchase -
3) It is relatively heavy and bulky.
4) It does not vacuum carpets satisfactorily.
5) The "mopping" in no way compares to a typical mop.

Positives:
1) You can mop without having vacuumed first.
2) It has no cord so it is very flexible in terms of the distance it can cover.
3) It has an LED screen for switching functions.

It is a product that is not sufficient for cleaning the house. If I had the opportunity to try it before buying it, I would not have bought it, especially given its cost. Not recommended.

I tried a vacuum/mop for the first time, and the lucky one was the Rohnson Mamba M30 Wetglide. And now I think I can't live without it...

First impression:
Inside the package we find the body of the WetGlide M30. On the handle there are 3 buttons: For power on/off, changing the cleaning modes, and self-cleaning.
The 4 cleaning modes are iSense with automatic power adjustment, Turbo for maximum power, Sterilization for hygienic cleaning with water electrolysis, and Dry without water for drying and vacuuming.
All these, of course, appear on the LED screen, along with the vacuum's status, battery level, and notifications. With every button press and in every problem, there are also voice notifications (in English) that inform you.
The clean water tank has a capacity of 650ml and opens very easily to fill. You can also add cleaning liquid to it, which is also included in the package.
The dirty water tank has a capacity of 550ml and is naturally divided into 3 parts for cleaning. At the top is the HEPA13 filter.
To make all this happen, there is the BLDC motor that provides 18,000Pa suction, 800 revolutions per minute on the brush, and the 28.8V battery that offers autonomy of up to 55 minutes.
The base opens so you can remove the brush and clean it if you want, and of course, the stand is included where self-cleaning takes place.
The Rohnson WetGlide M30 weighs 4.5kg.

Testing:
So what does vacuum mop mean? I had the same question. I had never used one before, we had been saying for years at home to get one and now the time has come. Essentially, it allows you to vacuum and mop at the same time. Just like the name says.
I was quite skeptical about the performance and especially the cost, as such devices from good brands start from €150-200 and up.
The more I used it, the more I understood its usefulness and the freedom it offers. Especially with a big and a small child who spend many hours in the living room, which is open plan with the kitchen.
Generally, it didn't struggle anywhere, whether it was some spilled liquid like water, milk, or coffee, liquid with solids like cereals, or even tougher stains I had to try for the review, like a nice mix of ketchup, mustard, and mayonnaise on the tile.
Of course, it also does great with dry stains like crumbs, dust, but also ground coffee, sugar, or flour. This is the nice part because you have the option of just vacuuming but also the option to mop at the same time for extra cleanliness.
Generally, I expected it would leave a lot of water during use, but it leaves very little due to the brush, which tries to be efficient with the minimum. And obviously, the amount of water does not translate to better cleaning, if someone wanted to compare it to traditional mopping, just to get ahead of that. In 1-2 minutes it has dried, depending on the temperature, of course. And it didn't leave marks either.
Its performance was equally good on tile, marble, and parquet, which is what I have at home. Obviously, it's not for carpets, I mention this because many people ask about these types of devices.
Something I messed up as a beginner and hadn't considered is to empty the dirty water tank immediately after each cleaning cycle. You might say, don't you do the same with a mop? Well, yes, but because it wasn't in front of me, I didn't remember. The first 1-2 times I used it and forgot to empty it after a day, it smelled really bad (which is logical).
As for the weight, it is definitely more comfortable than a classic stick vacuum, as its weight is at the bottom. Definitely more comfortable than traditional mopping as well. It moves smoothly and easily around the space and turns as it should. The noise is normal and not disturbing.
I should note that the vacuum does not start in an upright position as soon as the power button is pressed. It goes into standby and starts when released, which is quite convenient in case it is pressed by accident or you are in the middle of moving it.
And of course, the self-cleaning feature is extremely, extremely convenient so you don’t have to do anything. You place it on the base, and as long as there is water in the tank, it does it by itself. Of course, after 3-4 times, I also washed the brush manually with hot water. From time to time, the base also needs cleaning at the brush slot.

Final verdict:
The Rohnson WetGlide M30 was recently released and costs about €300. There are more affordable models in this category, but from what I see, they lack a bit in features and especially autonomy.
It may not replace the classic mop 100%, but for daily quick use for an unexpected stain and for maintaining floor cleanliness, it does an excellent job. These devices are lacking due to their design in use in corners, under low furniture, and if something needs to be scrubbed really well and you trust your muscle power and experience more.
I’ve had it in the kitchen for 3 weeks now and it’s needed somewhere every day, apart from cleaning the whole house. And it will stay there. It’s one of those devices you might snub at first, but after trying, buying, or using it, they seem so necessary. Maybe not necessary, but definitely useful and handy.
