The positives of the vacuum cleaner:

* It doesn't release dust into the environment...half the dust that it absorbs. For the first time, I can clean without getting dirty, without making the room I just cleaned smell.
* Sturdy construction, inspires confidence.
* Flexible on its wheels - moves in all directions on the floor.
* Long and very flexible plastic suction hose.
* Easy disassembly of the device, easy cleaning.
* Relatively low noise for an electric vacuum cleaner. Let's say it doesn't drown out the stereo playing in the background (to motivate the vacuum cleaner operator during the cleaning phase!).
* Satisfactory suction power. Not for hysterics, as we will see below.
* Water - water is nice!

The negatives of the vacuum cleaner:

* Bulky and heavy. It weighs 7 kilograms and is quite bulky, making it difficult for the homeowner of a small house with a lot of furniture. In short, it prefers "open" spaces. It is good to see it in a store before buying it, in order to "weigh" it in relation to your home.
* The vacuum cleaner, when in use, should be used in a horizontal position and never vertically. In a vertical position, there is a risk of dirt coming out of it (not to mention the risk of electric shock). In any case, it is heavy and not particularly suitable for handheld use like small bagged vacuums. Fortunately, its movement on the floor is aided by the wheels it has.
* The satisfactory suction power will not satisfy those who expect their vacuum cleaner to be able to lift a carpet in the air or stick the nozzle to the floor with the power of its force and not come off...
* The vacuum cleaner needs to be disassembled, removed, cleaned, and the water tank dried after each use. This means that its use is not suitable for quick clean-ups. For small messes, the homeowner should have a small handheld vacuum cleaner nearby or simply an old good common broom and dustpan!
* The parquet, mattress, and upholstery nozzles are sold separately and are not included in the package.
* Given that the contents of the water tank (with the dirt!) will end up in the toilet bowl, the user is obliged to clean the floor from small objects that the vacuum cleaner usually finds along the way: tissues, napkins, coins, and other things. Either they should be picked up before vacuuming or the dirty water should be poured into the sink afterwards to avoid clogging the toilet - which, if you are a genuine homemaker, means you will have to clean the sink afterwards!
* Finally, the price of the vacuum cleaner will discourage many. For those who are unable to pay for it, even in installments, consider the option of buying a Singer water vacuum cleaner with less money, after getting to know it in one of the stores that sell them.

Personally, despite the quirks and peculiarities of the Karcher DS-6, I have not regretted my choice. I may take an extra fifteen minutes for all the meticulous details and side tasks, but...finally, civilization!

When you pay, you get. I have written a review for this vacuum cleaner before and I am coming back to help potential buyers. In the positives, German quality and absorbency that I don't think exists in any other vacuum cleaner on the market. For example, when you have the special lid closed to reduce the pressure in the suction hose, you need strength to clean. The accessories, although few, are stored in the vacuum cleaner while the filters last a long time and can be washed with water and a brush. The bin, in combination with the filters it has, captures everything. You can truly see the house clean. The bin needs cleaning after use and where it really impresses is that you can see the dust and dirt it collects from a house. The spare parts are a bit pricey but they last a long time. Can be used for dry and wet cleaning. It requires a special liquid that you pour into the bin's water to prevent foam and it is sold in various scents. You clean and at the same time the space is scented. Cost ranges from 9 to 11 euros and it is good for several uses. Its size is a problem as well as its storage, but its advantages outweigh its disadvantages. Ideal vacuum cleaner for hypochondriacs!

It's like having a Smart and getting the X5. Day and night. Classic vacuums are more flexible, but when you "drive" them two or three times, they get stuck. I use it on the tiles and on the stairs for the carpets because you think it will loosen the tiles and it's easier to clean. As for the carpets that have a "d" label, we had some concerns, but to clean the carpet, you have to adjust the lid on the handle so that it doesn't pull too hard. We were torn between this one and one with three filters. We preferred the Karcher because it doesn't release anything behind that the eye can't see, and I didn't want to blow and clean filters every three hours and inhale the smoke. As for cleaning the bin, it's a habit. As a friend mentioned in a previous post, I also add a few drops of essential oil and the house smells nice. If you have something to clean urgently that has fallen locally, it's difficult to prepare it just for that. You also need a rechargeable handheld vacuum.

AFTER ONE YEAR OF USE
The vacuum is indeed worth its money. I rarely add essential oil because the bottle fits where the deodorizer goes, and after a while, the plastic melted. I wash the first filter occasionally. It's a hassle. The second and third filters are like new. If you already have a vacuum, don't buy it. You will get bored using it. It only needs a handheld vacuum. It sucks strongly on both carpets and floors. It's quite difficult to handle, and you have to empty and wash the bin every time, but when you see what the bin has collected, especially the things that the regular vacuums without water can't see, it's worth the effort. In the advertisement, they empty the bin in the sink. Don't do it at home!!!

The whole process is a hassle. The vacuum hasn't had any issues. I haven't changed any filters yet. I only clean the first one occasionally. The positive aspect is what I mentioned above. It doesn't have filters to clean and release smoke, and it doesn't release anything behind that the eye can't see.

Really the best vacuum cleaner I ever had. The water filter system provides not only strong suction but also does not lose its power over time. No matter how much time passes, it will be like the first time, which is generally a problem with electric vacuum cleaners. In bagless vacuum cleaners, the problem is that every now and then you have to thoroughly clean the filter either with water if it is washable or with air pressure if it is not washable, otherwise it loses its power and smells. A real hassle. With bagged vacuum cleaners, you are constantly dependent on buying bags. With this specific Karcher water filter, you simply empty the dirty water, clean the container, and once it dries, you are ready to use it again. The only thing you need to keep in mind is not to forget the container with the dirty water because it will start to smell. It is a bit large in size, but it doesn't bother you when moving around the house. It has a long cord and accessories that all vacuum cleaners have. It is a bit expensive but worth its money.

I have had the vacuum cleaner since 24/4/18, so the description will be relevant. However, I will update for any developments and impressions. I hope to help future buyers!

--------------------- Update 1/10/2018 ---------------------

As a first impression compared to the vacuum cleaner I had before (a Mielle Jazz with a bag), it's like night and day.

During operation, the classic musty smell is replaced with a feeling of absolute cleanliness. I added 3-4 drops of eucalyptus essential oil and the whole house smells great.

Because it filters through a water container, its performance remains consistent, unlike its predecessor, which had a decrease in performance with each use. Additionally, the house stays clean for more than 2-3 days, except for the kitchen for obvious reasons!

Indeed, it makes a bit of noise at 82db, but with a pick at 500hz, it seems to not be bothersome.

--------------------- Basic equipment ---------------------

The basic accessories include: a nozzle for floors and carpets, a nozzle for corners, a small nozzle for sofas (I used this to clean the mattresses), and a small bottle of anti-foaming agent (optional, but recommended by the manufacturer for each use. I haven't used it yet, and it still works fine. Note: it is necessary to use the anti-foaming agent because sometimes the water foams, and if you don't notice it in time, it can reach the motor and cause damage.

Maintenance and tips for proper operation:

1) After each use, clean the nozzle from the hair and (importantly) clean the container (it collects a lot inside), otherwise it will accumulate dirt around the container, which is difficult to clean and causes a bad smell. After cleaning, let all the components dry.

USING ANY SOURCE OF HEAT IS PROHIBITED - RISK OF DAMAGE

2) The second stage of filtration also needs cleaning. I do it every 5th use or every 1-2 weeks. For cleaning the container and filter, I use diluted Vanish with water (1/20), spray it, leave it for 2 minutes, and rinse. It's a process that needs to be done and takes no more than 10 minutes.

Damage - Malfunctions:

--------------------- Update 1/10/2018 ---------------------

The floor/carpet nozzle:
The cleaning system consists of two parts that come into contact with the floor, brushing it and keeping the soleplate slightly above the surface to ensure smooth airflow. 1) The front part is a brush that we all know. 2) The back part is a rubber attachment similar to a window cleaner. Both are placed on the same plastic piece that lifts with the help of two springs.

The second attachment quickly deformed and got stuck, most likely due to the mentioned malfunction that may have occurred.

The springs were sliding inside the seats, resulting in an increased distance between the ends, dramatically reducing their effectiveness. This led to the attachment not only being tiring to use but also not cleaning properly due to the empty air it created.

Temporary solution: I removed the rubber!

Permanent solution: I enlarged the seat with pliers, put the rubber back in place, and everything is fine now.

To the manufacturers at Karcher, a little better quality control... It's a shame that such a good product has such small problems!

Update 10/10/2019
The nozzle, after the small repair I did, is still working without any problems and the windshield wiper rubber has returned to its original shape!

I noticed that if I fill the container slightly above the max mark, the water does not foam
