They can be categorized into cold water high-pressure washers, hot water high-pressure washers, electric motor-driven high-pressure washers, and gasoline engine-driven high-pressure washers.
Hot water washers include a heating device, using a combustion chamber or electric heating element to heat the water. However, hot water washers are more expensive and have higher operating costs (because they require diesel or electric heating), but many professional customers still choose them.
Based on the driving engine, high-pressure washers can be divided into three main categories: electric motor-driven, gasoline engine-driven, and diesel engine-driven. As the names suggest, all three types of washers are equipped with a high-pressure pump, but they are connected to an electric motor, gasoline engine, or diesel engine, respectively, to drive the high-pressure pump. The advantage of gasoline engine-driven and diesel engine-driven high-pressure washers is that they can operate in the field without a power source.
Based on application, they can be divided into three main categories: household, commercial, and industrial. First, household high-pressure washers generally have lower pressure, flow rate, and lifespan (generally less than 100 hours), prioritizing portability, mobility, and ease of operation. Secondly, commercial high-pressure washers have higher requirements for parameters and are used more frequently and for longer periods, so they generally have a longer lifespan. Thirdly, industrial high-pressure washers, in addition to general requirements, often have some special requirements; waterjet cutting is a good example.
