How to Choose a High-Pressure Washer
The first stationary high-pressure washers appeared in the 30s of the twentieth century after in America the car from the category of luxury moved into the category of common personal vehicles. As technology developed, high-pressure washers were made in a compact, portable version.
High-pressure washers are divided into stationary and portable, which are also called mini-sinks. It should be understood that the dimensions and weight of a mini-car wash can actually be quite significant: “mini” it is only relative to a stationary car wash.
How to Choose a Pressure Washer
A stationary high-pressure washer, like 80 years ago, remains an attribute of service stations and car washes, so this equipment will not be considered in this article.
A good high-pressure washer is …
To choose a high-quality high-pressure washer that will meet your expectations, you need to start to figure out what kind of device it is and what details it consists of. In fact, a high-pressure washer is not a very complicated unit. Its main elements are a motor, a pump that supplies water, a hose with a washing nozzle, a housing and a cable.
High-pressure washers vary widely in their characteristics. What points should pay attention to when choosing such a device?
The class of washer
First, you need to decide which model you want to buy – domestic or professional. Household equipment is suitable for work on the plot, washing the car and the facade of the house, garden tools, etc. Such sinks are compact, designed for light loads – up to 1.5 hours per day, and their power is rarely above 1.5 kW.
Professional units with a capacity of up to 3 kW buy various service stations. Such car washes are at work in public utilities. The devices are sometimes equipped with a gasoline engine.
Special attention should be paid to this characteristic since the convenience of working with the unit depends on the length of the hose. For washing the car there is enough hose up to 4 meters long, but if you need washing for garden work and washing the facade of a country house, choose models with a longer hose – at least 7 meters.
This indicator determines the force of water pressure. Quality of cleaning is better if it is higher. For domestic needs, 70–100 bar is enough. By the way, good sinks, as a rule, have a pressure adjustment function.
This indicator indicates water consumption. High-pressure washers for domestic use usually spend 350-400 liters per hour. Professional models – 2-3 times more.
Most high-quality high-pressure washers are supplemented with a reservoir for detergents. This is a small container located on the hose nozzle. Mixing with water, the detergent gives an abundant foam. If this tank is not there, the process of washing the car, the floor tile or the facade of the building will be much more difficult.
Water intake function
This function is absolutely necessary if, where you will use the sink, there is no access to the water supply. It is enough to place the washing hose in a container (for example, in a barrel or a well) and water will begin to flow into the hose. Productivity at the same time will not be as high as when the water supply from the water supply system.
Pump body material
The most inexpensive material is plastic. It is light, cheap and does not fear corrosion. However, there is a minus – plastic is very fragile. And if a crack is formed on the case, it will be impossible to fix it, you will have to either change the case or buy a new car wash at all. But do not assume that the plastic casing of the pump – a sign of poor quality. Most household sinks are equipped with just such a pump. It’s all about the quality of plastic. The one used in models of reliable manufacturers is very durable and designed for long service life.
Brass and aluminum are considered more reliable, while the cost of products from them is much higher. Typically, these materials are made body professional sinks.
Complete with high-pressure washers usually comes with a set of nozzles designed for different purposes. The fan nozzle widely disperses water, it is suitable for washing large and not very polluted objects – walls or garden paths, with its help it is convenient to wash the foam from the car.
For very strong contamination using rotary nozzles, washing off dirt by contact, and mud mills.
Excellent addition to any high-pressure washer will also be the automatic on and off features, as well as the ability to turn the water jet around its axis.
