Max. pressure
The maximum outlet water pressure provided by the miniwash; for models in which the pressure is not regulated, this paragraph indicates the standard operating value.
The higher the water pressure at the outlet, the more efficiently the unit handles with chronic and stubborn contaminants. On the other hand, strong pressure requires high engine power, which affects the dimensions, weight and price of the device — despite the fact that not every dirt requires such pressure, and excessively intensive washing can damage the surface to be treated. Thus, the pressure is chosen by manufacturers in accordance with the general class of the miniwash. Thus, values
up to 100 bar are found in the most compact and low-power domestic models (see "Type"). A pressure of
100 – 125 bar is considered relatively low for household sinks, and most of these models are in the range of
125 – 150 bar — this is most often quite enough, taking into account the characteristics of the application. For professional units, the average is considered to be
150 – 175 barhowever, there are many models that give out
more than 175 bar.
Working flow
Water consumption characterizes productivity, that is, the amount of water that the unit can supply to the nozzle per hour. In most models, performance can be adjusted; for such cases, the characteristics indicate the flow rate at maximum power.
Higher
performance allows you to better handle large volumes of work and stubborn dirt, but requires adequate power — and this, in turn, affects the size, price and electricity / fuel consumption. So it is worth choosing according to this parameter, taking into account the features of the planned application. If we talk about specific numbers, then
low-capacity washes include models with a rate of up to 350 L / h, which are designed for simple tasks like cleaning windows in a private house, a small car or smaller equipment like bicycles. The unit with a flow rate of 350 – 500 L / h is perfect for washing cars and other similar tasks; if you have to deal with a large car like an SUV, you should pay attention to more performant options — up to 600 L / h. A capacity of 600 L/h or more makes it possible to classify the sink as a professional level, and values of 1000 L/h or more are typical for the most powerful and advanced models that can handle almost any task.
Power cord
The length of the power cord provided in the mini washer with an electric motor (see "Motor type"). The longer the cord, the more manoeuvrable the device is, the farther it can be installed from the outlet and the less you will depend on outlets. On the other hand, a long cable can create inconvenience by getting under your feet; however, many mini-washers with this feature provide a winding system (see "Functions and Capabilities") that eliminates this drawback.
