Min. pressure
The minimum pressure of water at the exit provided by a minisink. This parameter is indicated only for models in which the pressure can be regulated; for other cases, only the maximum (it is standard) pressure is indicated, see below about it.
High pressure during washing is not always desirable: on the one hand, it increases the cleaning efficiency, on the other hand, it can damage the treated surfaces. Therefore, in some cases — in particular when working with delicate materials or using foam — it is necessary to work at a reduced pressure. Detailed recommendations on this matter can be found in special sources, but here we note that the minimum washing pressure should not be higher than the maximum allowable — otherwise the unit simply cannot be set to the desired mode.
Power
Power of the pressure washer motor expressed in watts. Such a designation nowadays is generally accepted for all types of engines; it is quite possible to compare electric and gasoline / diesel units with each other. At the same time, for sinks with internal combustion engines, power in horsepower can also be specified (see above), but most often it is indicated as an addition to watts.
The higher the engine power, the greater the performance and pressure can be achieved at the outlet of the miniwash. On the other hand, this parameter directly affects the cost, as well as fuel / electricity consumption. In addition, in some situations, high power is unnecessary — for example, a delicate surface can be damaged by strong pressure. So when choosing, it is worth considering specific tasks, and not chasing the maximum possible power.
Detailed recommendations on this matter for different cases can be found in special sources. Also note here that most household models (see "Type") have a power of up to 2 kW (
battery units — most often up to 100 W, although there are exceptions).
2 – 3 kW are considered a fairly solid indicator for household sinks, and values \u200b\u200bmore
than 3 kW are already found mainly among professional models. Professional equipment, however, is also low-power (
up to 2 kW), but there are few such dev
...ices — in general, the power of such units is quite high, in a fairly large number of models it exceeds 4 kW.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.
