Pros

Cons

I would buy it again, but I decided to try the K5 full control.
30 April 2020 
An excellent device, it worked both in winter (in above-zero temperatures) and in summer, without any complaints, like clockwork, before that there were 2 Bosch sinks, they were used the same way, but they didn’t last more than 2 seasons, without any breakdowns. I bought a foam gun for it, and it became just a fairy tale. True, I always used water from the tap, I didn’t test taking water from a barrel and so on. As a result, the device went many kilometers away to wash a dacha in another region.
Reliable, takes up little space.
There is no way to properly wind the hose and electrical cable. If you change attachments frequently, the stopper on the attachments itself wears out a little.

There is no point in taking higher denominations. 3 kw no voltage no cottage. Will not work.
I'm just going to buy. waiting for my birthday to have discounts.
Expensive foam gun 3000 rubles.
a model with serious flaws
27 June 2019 
I won't buy another Karcher. And I won’t recommend it to anyone. They position themselves as a reliable assistant, but in reality they are just a burden. Maybe Karcher washers work for a long time, but probably on special ones. distilled water and use once a month. In short, g..but, not a car wash
At first it works flawlessly, but in the 2nd season it started to increase in pressure and does not produce 145 bar.
The life cycle is too short, I bought it in 2014, for the 3rd year of use (not intensive) I replaced the pump and rubber bands for 8 thousand. Now I am again asking for repairs for about the same amount. Pressure approx. 80-90 bar total. It doesn’t even remove foam from the foam generator. I washed my car about once a week. Rain water filtered from a barrel + filter before washing.

The German company Karcher has a reputation as the world's largest manufacturer of reliable cleaning equipment. The $270 K5 Compact is a high-performance model with a wide range of features for home use and beyond.

Design features

The model is produced in the corporate yellow colour, has compact dimensions of 520x300x280 cm and a moderate weight of 11.5 kg. During operation, it is located horizontally on the ground, it is brought to a vertical position only for transportation — wheels and a retractable handle are provided for this (the position of which for some reason is not fixed). Also, the unit can be carried by the side handles. With all the thoughtfulness of the body — the presence of places for nozzles and a gun, the model does not provide fasteners for winding the hose and cable.

Functional

If there are certain problems with the ergonomics of the device, then in terms of performance, the opposite is true. The K 5 Compact motor has a power of 2100 W, a flow rate of 500 L/h and a pressure of up to 145 bar. This is more than enough to clean garden tools, furniture, house facades, outdoor areas, bicycles, cars, and even motor homes. The hose length of 8 m is enough to walk freely around the car or in the yard. Thanks to Quick Connect connectors, all switching takes place in a fraction of a second.

A special mud cutter will remove adhering dirt, debris, dried clay, and nozzles with spot and fan spray will help clean hard-to-reach places and large surfaces. In an hour, the unit is able to clean the area up to 40 m²! In this case, do not worry about overheating. The water cooling system will ensure long-term trouble-free operation of the device. On the other hand, there are complaints about the plastic atomizer. Many complain that it bursts quickly enough, and replacing it is not cheap.

K 5 Compact can work with detergent, there is a tank where you can fill in liquid, and a tube that can be lowered into a container for collecting chemicals.

The sink draws water from a water supply or container, and provides good pressure even from the latter, so it is great for summer cottages without a centralized water supply, and a cleaning filter prevents debris from entering the system.

In summary, we can say that the K 5 Compact is an excellent sink in terms of performance and functionality, which you can safely buy for the claimed money, if you close your eyes to the shortcomings in ergonomics.
