I liked the soft/flexible hose and the convenience of the pressure washer in terms of its space (hose storage, accessories, etc.) and also in terms of mobility as it is flexible with its wheels. I also liked the on/off rotary switch, it is a bit more practical than others. I liked its pressure a little bit, but don't think it has a big difference compared to the Lidl one at 49 euros. I also liked how easy it is to attach and detach accessories to the gun. And now the negatives begin. It is not powerful enough as I would expect with 125 pressure and a metal pump, I had an Einhell 130 psi and it would remove the dirt from the car if you weren't careful. The nozzle only adjusts pressure intensity (like a faucet) and not beam width, which is a clearly more useful function. It also has a nozzle for higher pressure (those rotating ones with a narrow beam), personally I find it useless. Overall, it is not worth the extra money, mainly because it doesn't have the promised pressure and secondly because the water beam cannot be adjusted in width. Made in China with some plastic parts that don't look good at all, but for now it holds up. In the end, it is another product that makes me wonder why there are such good reviews, for me it has shortcomings and doesn't justify its price.

2nd Update - 0/2023
The machine is definitely worth its money.

Car washing becomes a game with the included foam sprayer (at least in my package: the one with adjustable flow).

It performs equally well on carpets (so the money for its acquisition is quickly recovered).

I am considering getting an extra telescopic wand (for cleaning solar panels) and the attachment for cleaning gutters.
===================================
1st Update 10/7/23
3 cars were washed in 1 hour!

The foam with the extra foam sprayer (which has adjustable dosage and is included in the set) becomes as thick as needed to "stick" to the car and soften any dirt!

Cleaning with a 'good' sponge and maybe a little with the soft brush included in the accessory set.

Then rinse with light pressure and dry with an absorbent cloth - ready!!

The cost of purchase will be recovered within two months!!

(photos will follow)
===============================================

Switching to this machine from a much more amateur one from Lidl (which was also "quite good") I saw a huge difference.
The use is 'domestic': balconies, garage, cars, carpets.
The accessories in this set are 7: two foam sprayers, two brushes, three different nozzles.
It has three power levels. At max, it can cut fingers - so: be careful with hands and feet. Ideally: wear a light work glove and definitely shoes to avoid injuries. But it also cleans (easily) the joints from ... everything.

One brush is great for this/these when combined with a good foam, it works wonders. Changing the accessories is an easy task (with a click) while it helps that the nozzles are securely placed on the base of the pressure washer and do not get lost.

Carpets are cleaned very easily, so you recover the cost within a season.

Cars are washed very easily.

It has a 6-meter power cable and a 6-meter hose with a metal pump, which provides significant autonomy.
Use a good quick connector so as not to waste water.
Always keep the water running and do a good rinse at the end (so that no water remains in the system).

Initially, I wanted the C135, but in the stores I ordered it from, they called me to inform me that it was no longer being produced and was not available from their suppliers! So, they suggested the core 130, which I have to admit I didn't really like visually. But because I had decided to get a Nilfisk instead of a Karcher, I chose this one since it was within my budget for a pressure washer. The comments from users played a role in my choice of Nilfisk over Karcher (although improper use also plays a part, but I don't know about that and didn't want to take any risks), and the fact that it has a metal pump in the blue version (I'm not exactly sure about the impeller).

The purchase was made for €175.
So, as soon as I received it, I reviewed its appearance. Since it is very small and practical for storage, it looks like a toy!

I mainly use it for my car, and it covers my needs. I also bought a nozzle specifically for the car to avoid any issues with the paint.

It is quite powerful, although I don't have anything to compare it to (in terms of specifications).

As for noise, a pressure washer will obviously make noise. Compared to others, it is relatively quiet. When you press the trigger, it runs smoothly, but when you release it, it makes a strange noise, obviously metallic, which sounds like a bird.

I have been using it for about a month, so I can't speak about its durability and such yet. I hope it will last me a few years.

It is good to get a separate filter, which is sold separately, to capture small particles. It requires proper care, like I imagine all pressure washers do, such as with the quick connectors.

We shouldn't use it under pressure and should turn off the switch when not using it for a while. After finishing our work, we should turn off the power and water, and press the trigger to release any remaining water.

If I were to buy a pressure washer now, considering the prices I see, I would prefer the 140 for mainly psychological reasons and because it is roughly around the €175 that I bought the 130 for.

I will update my review in the future to see its durability!
