The vacuum cleaner has very low suction power. It won't struggle on a thin carpet or rug. However, on a thick carpet or especially on a thick rug, it requires many passes over the same spot to extract water. On sofa fabric, it performed excellently (especially when the fabric is vertical), as well as on car upholstery.

The cleaning power on difficult local stains was insufficient, even with the help of scrubbing with the vacuum's brush. A rotary brush was used on a drill and had very good results.

The water extraction hose of the vacuum is very short and very flexible. Its length couldn't be longer due to the vacuum's low suction power.

If you want to clean an entire carpet like in my case, you will have to kneel and keep the vacuum very close to you. But not too far to the side in relation to the hose nozzle, because the hose bends. It forces you to always keep the vacuum behind your hand/elbow.

This specific version of the vacuum comes with a nozzle that has a small water collection container, so that the hose and the dirty water tank don't get dirty. Unfortunately, it is almost useless. I initially tried it because of the wider nozzle, hoping it would shorten the cleaning time. The nozzle cannot suck up any water if it has been sprayed and has had time to seep into the carpet/rug. On the contrary, it only pulls part of it if you immediately move the nozzle to suck it up while spraying. This means you can't let the liquid soak and scrub the carpet first to break the stain. Also, the sprayer on this nozzle is located on top and not underneath. You have to push the nozzle forward and not pull it to suck up the water. Therefore, the only case in which this specific attachment might be useful is if you want to go over your carpet, not to clean a local stain, but simply to clean the surface dust and give a fresh scent to any fabric due to the chemical cleaner.

The second attachment used to rinse the vacuum hose was quite a bit more useful. With the remaining water in the tank, you rinse the hose (which is not detachable), without needing to put the hose in a bucket of water to start sucking it up for cleaning. With the attachment, you can lift the hose vertically high and return the water it sprays back into the dirty water collection tank.

And since I reached the tanks, they come out/in very easily and fill/empty also very easily. A small downside is that the dirty water collection tank, although large, can only fill up to just below the middle. It has a plastic float inside that acts as a float, and when the level reaches a certain point, the vacuum operates and makes noise, but it stops sucking and you can hear it making a slight noise. You have to empty the dirty water for it to start sucking again. This results in the dirty water tank having less usable space than it actually does. However, it empties very easily and quickly, so it won't be bothersome.

Is the vacuum worth it in the end? In Greece compared to abroad, its price is a bit high and will probably depend on the type of use. I have a huge corner white sofa, which I cleaned from dust and local stains from shoes down low.
I also cleaned the upholstery of the ceiling, seats, and upholstery on the doors, floor, and trunk in the car. Those who have pets or generally have problems with odors in carpets/fabrics will solve this problem as well. The vacuum essentially claims to be a SPOT cleaner, and it doesn't lie about that. However, when it comes to cleaning large whole carpets, especially thick ones, it will tire you out during use and will take quite a while.

In conclusion, I have cleaned a huge white sofa that gets dirty easily, cleaned the car if it gets stained by sea salt/vacation stains, and cleaned two carpets every year (where the cleaning cost is quite high, as well as the fact that I can lend it to family members to use it too... yes, it’s worth owning it. With what I cleaned for the first time, I feel like I have already recouped my investment.

Since the cleaning products line is relatively expensive, I would like all versions of their new concentrated 2X cleaners to be released in Greece soon (at the same price, so half the amount is needed).
