I had absolutely no problems. I never even read the instructions; it's that simple.
I washed 2 rugs measuring 250*200, 2 seats, one for a child, and two runners.
I have more than half a liter of detergent left.
The detergent doesn't foam or smell, it didn't damage anything, and it cleaned quite well.
It really helps to rinse.
Each “line” is one liter of water in the detergent tank. I used 100 ml per 3 liters of water.
Where I had a stubborn stain, I left it wet with the detergent solution for 5 minutes, twice.
After washing, I went over them once more with clean water, since I have a pet and a child and wanted to avoid contact with the chemicals.
There were no leaks.
The motor didn't heat up; I took normal breaks to prepare the mixtures and clean the tank.
To store it, I added clean water, ran 1 liter through the hoses, and left it to dry for a little while so it could be stored clean.
Cleaning is the first step in maintenance.

Button for throwing water was working less than 1 week. I took it 1 year ago, now it’s breaks peace by peace. Too much heavy. Big space for water not means that it’s will handle more than 1 litre go take in. Upper 1 L it’s stop working, and u must throw water out so u can continue cleaning. Big for no reason.

Very good job in terms of suction for dust and lint on the floor.
On my rug, which is embossed, it doesn't clean so deeply, so there I use the Dyson, which is incomparable.
Now for wet suction, I used it to clean a rug, armchair, suitcase, and a seat.
The rug changed color. On the others, which were upholstery, afterwards there was a feeling as if the fabric was sticky. It didn't give you the sense of clean fabric. So I went over them again with a wet cloth.
Also, although I used 4 liters of water, which is the full capacity of the tank, there was very little water collected at the bottom of the collection bin. I realized this also from the fact that everything I cleaned retained a lot of moisture. Even though the special nozzle seemed not to suck up any more (i.e., it had pulled as much as it could), the rug and the armchair were still quite damp.

it sprays water from where it blows air from the sides above next to the fastenings. The filter doesn't matter, neither of the two... It does it with both... The old yellow one is much better than this one...

I am very satisfied with its performance and I used it first for cleaning the sofa and then for a rug in the living room. The water tank was a bit small but for its price the vacuum cleaner is quite good.

After 5 minutes of use, it throws dirty water from the upper side where the air comes out. Apparently, the filter that is supposed to be suitable for water, in the end, is not. The special sponge filter for water should be provided. Until we realized it, on one hand we were cleaning and on the other we were causing more damage to the sofa. This problem is well known and is mentioned by many people abroad as well. For Karcher, such a mistake is inexcusable.

One of the best vacuum cleaners I have ever tried. I had vacuumed the house with a regular household vacuum just a day before, including the carpets, and when I tried to clean it with this one, I couldn't believe my eyes at how much hair and lint it had collected in its bin! Then, of course, I cleaned my fabric sofa and both of my large carpets with its liquid cleaner!! Excellent results! It makes things so much easier and you immediately realize you are handling a professional-quality vacuum cleaner!

It is almost professional. On the downside, it only uses their own detergent and its size. It cleans well.

Its wet cleaning is very good and it also sucks very powerfully when you use it as a regular vacuum cleaner. The only problem is that switching from wet cleaning vacuum to regular vacuum is time-consuming, so you don't go through this process often, only when you want to clean the whole house 2-3 times a year.

I would suggest to anyone who tries to clean with liquid to remove the filter and the bag because they will smell bad from the moisture the next day

Amazing job

Unfortunately, when it activates to collect liquids from the bin, the liquids are splashed out as seen in the video! Also, the button that sprays water sometimes gets stuck and sometimes unblocks! I am not at all satisfied with the vacuum in terms of construction! I give it two stars because it has enough power to collect moisture from the sofa

Fantastic vacuum, I got it for upholstery and carpets. Minus one star, because in my opinion it should have included the special nozzle for upholstery and not have us pay extra for it
