Quite a good wash. Of course, it cannot be compared with a professional one, but for home use it is exactly what is required. Quite economical in terms of water consumption. The pressure is great. During operation it does not overheat at all. After it the car looks completely like new. I am pleased with the purchase and recommend it to everyone.
At the moment I don't see any shortcomings.

Washing equipment under the German brand Karcher is a guarantee of quality and efficiency. The K5 Classic high-pressure washer is an excellent, albeit expensive, helper not only in a private home, but also in a small production or car wash.

Appearance

In places, glossy plastic gives the model a spectacular look. The case is durable, reliably protected from shock and shaking. The dimensions of the sink are 870x350x430 mm and the weight of 13.3 kg is not the most compact, but thanks to the wheels and a comfortable high handle, it is easy to move even a teenager around the site. There is a hose hook on the body, but the power cord can only be wrapped around the body, which is some inconvenience.

Technology capabilities

The sink is equipped with an aluminium alloy pump and a water cooling system that protects the engine from overheating. This allows you to work continuously for 45 minutes. The performance of the model is 500 L / h and the working pressure is up to 145 bar, which means that with its help you can easily remove dirt of any age, wash sand and even small stones from the track.

Comes with mud nozzle and fan spray nozzle. Separately, you can buy a foam gun, brush and other nozzles to expand the functionality of the model. To deal with particularly difficult soiling, the device has a reservoir for cleaning agent.

What else?

The sink can take water from a tank, which eliminates the need to connect to the water supply in certain situations, and the 8-metre long high-pressure hose makes it possible to work with large objects, such as a jeep or van.

The K 5 Classic sink is sure to get the job done, but it costs a lot – around $350. So, if you want to save a hundred dollars, you can safely buy a unit from another manufacturer with almost similar characteristics, for example, Bosch Universal Aquatak 135, and for Karcher adherents, a compact model of the same K 5 Compact series will do.

  • Pick nozzle
  • Foam nozzle 0.3 L
  • Universal cleaner RM 555 1 L
