Any car owner wants to keep his car clean. But washing takes a lot of time - it’s not always possible to schedule for the right time, and sometimes the result is not happy (on older machines they often paint down under pressure). A famous proverb says: "If you want to do well, do it yourself." Many car owners buy individual mini-washers. One of these is Karcher K 7. Price, an overview of it and characteristics - further in our article.
Note: Karcher is a well-known German company manufacturing equipment for cleaning and tidying. Founded by Alfred Karcher in 1935.
Characteristic
Car wash "Karcher K7" is a universal tool for combating pollution. It can be used not only by car, but also in the household.
The Karcher K 7 Premium series was developed in 2014. This is a new generation mini-washer that works under high pressure. Water is supplied in two ways:
- From an external source (when connected to the water supply).
- Independently. The mini-sink has the function of automatically absorbing water from the tank.
But how to use such an apparatus in our conditions, if the liquid in the water supply system may contain dirt and other small mash? This question worries many motorists. But do not be afraid - there is a filter inside the unit. It pre-screens out all unnecessary deposits before the fluid enters the outside.
Device
This unit consists of several elements:
- Electric motor (asynchronous, water-cooled).
- Pomp (pump).
- Hose.
- Filter.
- Spray gun.
An electric motor is the main component of the Karcher car wash. Also note that some devices from this company were equipped with gasoline units. But due to the high noise, harmful odor and a number of other shortcomings, they are rarely found in the market of mini-sinks.
An electric motor drives the water pump. The latter draws water from the tap and feeds it to another channel under pressure. Typically, the pump is designed to handle liquids up to 8 liters per minute. Note that the material for the pump can be of two types:
- Plastic composite. It is applied on sinks of a budget class. These include the "Karcher" K2, K3 and K4.
- Alloy with silicon. These are silumin pumps. Are used on sinks of a high class - K5 and K7.
Particular attention is paid to the hose. So that it does not deform under high pressure, it is made of durable reinforced mesh. The hose has two high-density plastic layers.
Further, water under pressure falls on the spray gun. The latter has a specific structure with tips and slots. The manufacturer produces several nozzles for working with different types of surfaces. One of them is a mud mill. Tips can have a different degree of spraying.
Specifications
"Karcher K 7" refers to high-end sinks. The maximum pressure created by the device is 160 bar. The design uses a silumin pump. The connection is through the water supply (but also the unit can work autonomously, since it has a built-in capacity).
The maximum productivity of the Karcher K 7 apparatus is 600 liters per hour. The inlet water temperature is up to 60 degrees Celsius, which allows you to wash pollution of any complexity. The power of the electric motor is 3 kilowatts. The washing mass of Karcher K 7 is 20.3 kilograms.
Equipment
The kit for a mini-sink includes:
- Reinforced rubber hose. Its length is 10 meters.
- Gun with jet nozzle.
- Mud cutter.
- Nozzle "Delta Racer."
- Adapter adapter for connecting to a garden hose. The diameter of the latter is ¾ inch.
- 300 milliliter foam nozzle.
- 1 liter cleaning agent.
- Wipe for cleaning.
Cost
How much does the Karcher K7 German mini-car cost? The cost of the unit is from 30 to 40 thousand rubles.
At the same time, the manufacturer gives an annual guarantee for the operation of its equipment. This applies to all Karcher mini-sinks, including the K7 series unit.
Owner reviews: advantages and disadvantages
What do motorists say about this wash? Many note the high pressure generated by the pump. Karcher K7, unlike budget models, really works like a contactless sink. Water under a pressure of 160 Bar can remove even the most persistent contaminants - they do not have to be rubbed manually with a washcloth. Also in this model there is place for storing a foaming agent and a mud cutter. The user can change the pressure directly on the gun. This is a big plus - say the reviews. The owners also note the possibility of using many additional accessories.
As for the shortcomings of the Karcher K 7 mini-washer, reviews point to a too rigid reinforced hose. It’s hard to work with him. There is also no drum for winding wire. The filter element extends beyond the housing. The dimensions of the unit are rather big, so you have to think in advance about where to store this unit.
Otherwise, users are satisfied with the purchase. Many people choose the Karcher K7 mini-sink thanks to the aluminum pump. It is much more reliable than plastic and is capable of delivering good outlet pressure. The hose is not damaged even when the car wheel runs over. But the lack of a wire drum makes operation difficult.
Can I use the unit in winter?
This mini-sink can work with water heated to a temperature of 60 degrees.
Therefore, the operation of this unit at low temperatures is possible, but only when connecting a warm source (since there is no built-in heater here).
Conclusion
So, we found out what the German Karcher K 7 mini-sink is. Having a contactless washing at home is a very big plus. At any time, the owner can clean the car of dirt in a short time, and most importantly, for free. For what period will this unit be able to recapture its value? It all depends on the frequency of use. But as reviews say, the average payback period is two years. Many will say that this is too long. However, the main decisive factor is time saving and high-quality result.
