â–º Cold water pressure washers don't change water temperature. This products are the most common and sold; vast catalogue of professional and economical models;
â–º Hot water pressure washers have more than one diesel boiler which enhances their efficiency due to the high temperature of the outgoing water; this machines are to be used by professionalsi;
â–º Petrol pressure washer (cold water) are designed for locations in which there is no electricity; the petrol engine requires a higher price and operating costs.
High-pressure pressure washers are cleaning machines which use a pump to put normal household water under pressure to achieve a much higher cleaning and degreasing power. They are divided in 3 subcategories depending on type and power supply:
Cold Water Pressure Washers:Â the most popular and sold, since they use home water which, once brought to high pressure, provides excellent cleaning power. These machines are fundamental since they are suitable for many uses thanks to their many accessories which allow cleaning walls and driveways or cars, motorcycles, bycicles or agricultural machines. This category usually includes more affordable pressure washers, however, you can also find heavy-duty cold water machines used in construction and industry.
Hot Water Pressure Washers: unlike cold water models, these machines feature a diesel boiler which brings the outlet water to high temperatures, improving effectiveness and cleaning power. This is due to the degreasing power of heat, which avoids using higher pressure or aggressive detergents. However, the boiler makes them heavier and bulkier,and therefore less practical. These machines are very popular among professionals who have to clean particularly dirty or greasy environments, such as workshops or in food industry. In this category of pressure washers we can also find models suitable for amateur and semi-professional use
Petrol Pressure Washers: they can be considered independent machines since they do not need a source of power supply. Very appreciated for the engine power, up to 10 HP in high-end models, which allows to reach much higher pressures and flow rates than single-phase electric machines. Petrol engines offer higher reliability, but also higher operating costs, noise levels and lower convenience due to their weight. Very popular among professionals and companies for the great power delivered by the engines, which allows water to reach pressures and flow rates that an electric motor cannot match. In addition, and perhaps this is the most important aspect, the possibility of use in any condition makes it an excellent machine also for its versatility.
All major brands producing high-pressure washers which are listed on our website (Karcher, Comet, Lavor, Annovi Reverberi & Stanley Black & Decker, Michelin, etc.), are of a good quality, it is important to remember that in order to make the right choice you should understand the classification of these pressure washers and identify the right level of machine to buy. The element you should look at first is always the delivered pressure, the data more directly associated with the level of power of the machine, however, it is not always high pressure which determines the quality level of the electrical pressure washer and the high durability. So it is important to evaluate a sufficient pressure level, but is even more important to establish the frequency and intensity of use (A) of the pressure washer and what type of objects or surfaces (B) are intended to be washed. We therefore provide the first ultra-concise handbook based on our personal rank, visible also above, from which you can take notice:
We provide you now a real QUICK HANDBOOK for the FILTERS placed in the column below to help you to carry out a fast and effective selection and identify, in a few simple steps, the specific model that suits your needs in this review of about 350 electric pressure washers.
