It is a vacuum cleaner whose main job is wet cleaning (biological cleaning). It makes quite a bit of noise, but I know that this type of vacuum works that way. The work it does is evident when you go to empty the black tank that is for dirty water. Its operation is satisfactory. It definitely requires caution when pulling it because it doesn't easily go over carpets (just like practically other vacuums don’t easily go over them either). Also, it can't easily ride over its own cord. So this means we need to be careful to maintain it. Also, whatever we do with the vacuum, we do it carefully without violent movements because no matter how high quality the plastics are, they are still plastics and need just attention. I bought it a month ago and I have cleaned 6 carpets, a sofa, and a mattress. The cleaning it does has left me satisfied. In case you want something more, you repeat the process. The cleaner I used is the carpet pro professional. Half a scoop in 4 liters of water is the dosage of detergent I use. Finally, it would be very good if there was also a small attachment for spots where you can't use the large one.

Well guys, because I see many negative comments here regarding its functionality, being an owner for five months now, I also want to write about my experience with this specific vacuum cleaner. Indeed, if you don't pay attention, the machine can easily tip over and the motor can burn. Personally, I got stuck on the side auxiliary wheels and had no issues. If the bin collects too much foam, it penetrates the air filter and goes into the motor, resulting in burning. Personally, this happened to me the first time I used it and I immediately stopped the vacuum cleaner, opened it, and cleaned it. Then I researched why this happens and the solution was to buy an anti-foam agent, specifically the Kärcher 6.295-873.0 Foamstop 125ml, and since then I have been saved. The quality for its price is okay. Be careful when closing the bin, how you position the soap container, as there is a high risk of breaking one of the locking mechanisms on the sides. For its price, it is very powerful and strong, I have cleaned all the carpets in my house and it continues to work perfectly. Don't expect miracles with this money, for amateur use it is great!

It was mainly purchased to be used for cleaning the car (interior, floor-carpet, seats). However, in order to use it for this purpose, the company sells the special attachment (wet suction nozzle) separately, with a cost starting from about 24 euros.
But let's start with the description. It has the necessary components that such a vacuum cleaner should have. It includes a dust bag for solid suction. For liquid suction, it consists of two internal tanks, one for clean water where you add the chemical, and one where the dirty water ends up. For solid suction, these two smaller-sized tanks are removed, and the larger external one is used together with the dust bag.
As a vacuum cleaner for liquid suction, it did a very good job on the car floor-carpet and seats. In an old vehicle, where this type of cleaning had never been done before, it changed the appearance and color of the seats, as well as the carpet. I have recorded in a video how the water came out after the first application... However, when it was first put into operation, the pump that pushes the water to the wet suction nozzle did not work because it did not fit well in the tank with clean water. This was probably due to poor assembly. It was resolved, but it frustrated us.
But as a vacuum cleaner for solid suction, it does not have much power. It's mediocre. I don't know why, but it doesn't have enough power to easily pull up dirt.
Country of manufacture, Romania.

I am reviewing the vacuum cleaner evaluation.
I had given it 1 star, now I give it 3.
It takes a little time to learn its weaknesses, but then it does the job it is intended for.
So, I will briefly write the disadvantages/advantages.

CONS:

- Do not buy it for dry vacuuming, it requires a bag and it is very noisy. I would consider it poor in performance for dry vacuuming.
I bought it specifically for wet cleaning (car interior, carpets, sofas, etc).

- The vacuum easily topples over! It even falls by stepping on its own cord. Be careful because it is not completely waterproof, if you catch it in time, you might save the motor...

- When you open it to remove its bins, there is a small round seal that attaches to seal the nozzle pump. I lost it within 3 uses and the pump didn't work as it lost pressure. The service told me it is a common occurrence. Luckily, it is a small cost (around 2€).

- DEFINITELY after each use, let the parts of the vacuum dry COMPLETELY!! Remove its filter!! It got moldy in just a few uses and had to be replaced!!
Also, rinse the nozzle with 1 liter of clean water and the attachments in general.

PROS:

- With hot water in its bin and the company's soap, using the correct technique/patience, you will achieve good results. You will also notice it from the dirt collected in the dirty bin.

- On dirtier fabrics/carpets, etc., I first spray the detergent with hot water, let it work for 2-3 minutes (not letting it dry) and it cleans better. You can repeat if it hasn't cleaned to your desired level.

I wonder about the reviews! I was deceived by them and bought it for 250 euros, after my previous vacuum cleaner, which I had for 6 years, a Chinese one with a disposable bag, bought for 40 euros, had twice the suction power. On a simple carpet, it doesn't pick up the dirt and fluff, it takes 4-5 passes in the same spot, the cleaning time is 3 times longer than the cheapest Chinese vacuum cleaner. For floor washing, it takes hours to do half the job, you don't even consider doing it.. for fabric cleaning, for example, a sofa, it freshens it up but you need to have the ability to take the sofa outside, otherwise, due to the weak suction, all the water remains in the fabric and doesn't dry, also it doesn't clean on its own, it requires a lot of hand scrubbing with a brush to say that it removes light stains. For example, ash from the fireplace doesn't go away with just the vacuum cleaner. Overall, the vacuum cleaner is not worth buying, even if it cost 50 euros, it doesn't do the job of a vacuum cleaner, so you should get another one! In no case would I say it's German, but Bulgarian, like some rotten woodworms that emit smoke and fill the house! Finally, be careful, it is completely incapable for household use, especially if you have a child and need it permanently, it triples the cleaning time. Finally, I bought another one, much more powerful, for 80 euros, I take it outside and with one pass, I quickly cleaned. The vacuum cleaner has been tested for 2 months and it is ungrateful!

My review concerns only carpet cleaning. Coming from a similar Phillips vacuum cleaner that gave up after 20 years of use, what will disappoint you in this vacuum cleaner is that it is made in a simple and economical way. The goal is obviously to limit costs, as without being poorly made, it has the following disadvantages:
- It does not have much power to suck up liquids from the carpet, which means that the circular motion of the liquid (with the soap) on the carpet is not effectively done, and therefore it does not clean as well and the carpets are slightly wetter. It also makes a lot of noise.
- The foot that sucks up the liquids is very narrow, so it covers less surface area and cleaning is delayed, not to mention that you have to press it because it does not have the power to suck up.
- The container with clean water and soap is small and needs constant refilling.
- The way the motor is attached requires attention because many times the pump makes noise because it does not fit properly.
- It is narrow and has small wheels, making it easy to tip over.
In summary: if they paid attention to some details, it would be a much better product, and furthermore, the fact that it is simply constructed and does not have any foamy plastics, sponge filters, etc. shows a device that will last for several years.

I will give it only one star because it is designed to work with both solid and liquid waste, necessarily with the solid waste filter on the top, and while it is designed to be squeezed, it leaks and eventually gets destroyed (because it is made of paper) and needs replacement. Also, almost always a few liquids spill on the floor of the yellow inner bucket and not on the black one, which is useless. The white bucket where we put the diluted cleaner also has a filter that needs attention because it gets dirty easily. It was tested in the first year of operation with more than 30 square meters of carpets in 3 houses (the main reason for purchasing it). Since then, it has been used with the car nozzle on velvet chairs, which it made new again, and on countless cars that it literally revived. It even managed to lift a lot of dirt from a seemingly spotless tile floor (using a thick chlorine solution). It happened while cleaning a carpet and even though it was full of liquid, water spilled and went outside. Fortunately, the machine did NOT break and continues to work for the third consecutive season.

In my opinion, the vacuum cleaner is great both as an electric and as a washing machine. I have washed everything from carpets and sofas to our mattresses, and it has a very good suction power for picking up liquids and removing odors, which you can see when you empty the bin. It's not exactly quiet, but it doesn't bother me. It also comes with plenty of attachments for both uses of the vacuum cleaner. Additionally, you will need to purchase the small nozzle separately in order to easily clean car seats or other small surfaces, which costs around 27 euros. As for the bins it has, each one can hold 4 liters of water, and the attachments seem very reliable. Despite some negative reviews I saw, it turned out that they didn't apply to me, as it does its job more than well. One downside is that it doesn't have a place to store the power cord, but in the end, you can wrap it around and it's all good. If you take care of it properly after each use, you won't have any issues, and also be careful not to drop it while using it, as there is a chance of damaging the motor. I should also mention that when you finish the task you're doing, you should let it run on its own by adding a liter of water inside and leaving it like that to flush out any remaining dirt or residue. Overall, I would definitely buy it again, which is why I give it 5 stars.

Update 8/4/2021: After almost a year and a half, it has truly proven itself. I have cleaned around 8 cars and everything is going well. I'm including a link for you to see a small sample for those who claim that the vacuum cleaner doesn't have good suction.

Positives:
Build quality
Ease of use
Ease of movement
Power

Negatives:
Noise (without at least two levels to reduce it)
On/off for both spraying and vacuuming (no adjustment for water pressure, quantity, or spray beam)
Storage of accessories

Really powerful vacuum, it feels like you're next to a fighter aircraft when you open it :)

The truth is that it should have at least two levels to reduce the noise when you just want to clean and not do a general cleaning, but I don't think anyone buys it as their main vacuum...
Another missing feature is that there is no adjustment for the spray nozzle, resulting in a little extra water being sprayed to the right and left (but nothing drastic).

In terms of transportation, it's fine for what it is... not too heavy and with very good wheels... The storage of a vacuum of this size... of course, it's a problem. This is also contributed by the fact that there is no way to store the accessories (not even the power cord). But as I said... you don't buy it as your main vacuum...

After cleaning with spraying, you feel that the fabrics are wet (chairs, cushions, etc.), but it definitely reduces the drying time by a lot... I still have reservations about whether it removes all the detergent it sprays or if you need 2-3 passes to be sure.

Overall, I am satisfied with the purchase (especially from the store that offered several extras at a very good price)...

Regarding a comment above that it's the same as spraying and vacuuming with a wet vacuum... it's not... the vacuum sprays and immediately pulls most of the liquid before it has a chance to soak deeply, but at the same time, it releases a lot of water with pressure to clean.

In the next few days... it will be tested on carpets and also on the car, so I will have a more complete picture...
