The vacuum cleaner has very low suction power. On a thin carpet or rug, it won’t struggle. However, on a thick carpet or especially on a plush rug, you need to go over the same spot many times 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 tough local stains was not sufficient, even with the help of scrubbing with the vacuum’s brush. A rotary brush on a drill was used and had very good results.

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

This particular version of the vacuum has the nozzle with the small water collection tank, so the hose and the dirty water bin don’t get dirty. Unfortunately, it is almost* useless for general use.
I tried it initially due to the wider nozzle, hoping it would shorten cleaning time. The nozzle, because of its larger opening, sucks even more weakly.

So the only case where this accessory might be useful to you (and probably what it’s intended for) is if you want to clean your carpet to remove pet droppings, etc., and have them end up in the nozzle’s built-in tank without dirtying the hose and dirty water bin, which would require you to clean everything well to prevent odors.

The second accessory, which you use to rinse the vacuum’s hose, is useful.

With the water from the bin, you rinse the hose (which is not detachable), without needing to put the hose in a bucket of water to start sucking so it cleans itself. With the accessory, you can simply lift the hose vertically and the water sprayed returns to the dirty water collection bin. Easy and effortless.

And since I mentioned the bins, they come in and out very easily and fill/empty just as easily. A small negative is that the dirty water collection bin, although large, is only allowed to fill up to just below the middle. It has a plastic part inside that acts as a float, and when the level reaches a certain point, the vacuum still runs and makes noise, but stops suction and you notice a slight increase in noise.
You need to empty the dirty water for it to start sucking again. As a result, the dirty water bin has less usable space than its actual capacity. However, it empties very easily and quickly, so it won’t bother you.

Is the vacuum worth it in the end?
In Greece, compared to abroad, its price is higher and it will probably depend on the type of use.
I have a huge white corner sofa, which I cleaned from dust and local stains from shoes at the bottom.
I also cleaned the headliner upholstery, seats, and upholstery on doors, floor, and trunk in the car.
Anyone with pets or generally with odor problems in carpets/fabrics will also solve this problem.

The vacuum essentially claims to be a SPOT cleaner and it’s not lying about that. However, for cleaning large whole carpets and especially thick ones, it will be tiring to use and will take quite a while.

In conclusion, for me, with the cleaning of a huge white sofa that gets dirty easily, cleaning the car if it gets stained by sea salts/holidays etc. stains, cleaning two carpets every year (where the cleaning cost is considerable, as well as the fact that I can lend it to family members to use it too...yes, it is worth owning it.
With what I cleaned for the first time, I feel that I have already recouped the cost.

I do not recommend it exclusively for use on very large carpets, it is not made for those, you and the machine will both get tired.

Since its line of cleaning products is relatively expensive, I would like all versions of its new cleaning products, which are 2X concentrated (at the same price and thus requiring half the amount), to be released soon in Greece.
