Currently, high-pressure washers are mainly divided into cordless models and household 220V plug-in models. The biggest advantage of cordless models is their portability, but due to voltage and water pressure limitations, they are only suitable for high-rise residents' car washing needs.
For homes with yards, it's crucial to choose a 220V plug-in model. The voltage and water pressure are more advantageous, and you don't need to worry about battery life, making the cleaning process more comfortable.
High-pressure washers come in induction motor and series-wound motor types; the essential difference is whether they have brushes or not. If your budget allows, it's recommended to prioritize induction motors, as they have a longer lifespan and lower noise.
When choosing motor power, also consider this; prioritize higher power for a better cleaning experience. Generally, an induction motor of 1800W or higher is sufficient for yard cleaning needs.
Choosing a high-pressure washer requires comprehensive consideration of its type, performance parameters, and applicable scenarios. Electric models (noise <75dB) are suitable for home and small commercial use, with a pressure range of 140-200 bar and a water flow rate of 5-10 L/min. Fuel-fired models (pressure 200-300 bar) are suitable for industrial applications, offering unrestricted power and stronger performance. Key parameters such as pressure (bar/psi) directly affect cleaning effectiveness, while flow rate (L/min) determines efficiency; it is recommended to match the pressure level according to the type of dirt. For portability, a lightweight design (<15kg) with wheels and a telescopic handle enhances ease of movement. A variety of accessories (such as 0°-40° adjustable nozzles) expands application scenarios, such as vehicle washing or floor cleaning. After-sales service (such as a 2-year warranty) and professional technical support are equally important, reducing long-term operating costs.
