Usage
Generally, pressure washers can be divided into household and professional types. If you use the washer for less than 50 hours a year, you only need to buy a household washer. They are relatively cheaper, lighter, made of simpler materials, and not heat-resistant. If you use it for more than 100 hours a year, you should consider a professional pressure washer. These are larger, made of durable materials such as copper alloy pump heads and stainless steel valves, and are naturally much more expensive. Therefore, the choice depends on the consumer's needs.
Hot and Cold Water
Pressure washers can also be divided into hot and cold water types depending on the application. Most on the market are cold water types, which can be used by simply adding room temperature water from the tap. However, some commercial establishments require hot water washing, in which case a hot water type pressure washer must be specially purchased. Using a cold water type with hot water will quickly damage internal parts, including the pump, resulting in more harm than good.
Spray Nozzles
Different spray nozzles produce different cleaning effects. For example, round water jet nozzles can increase cleaning efficiency, fan-shaped nozzles can rotate to create low-pressure sprays (for soapy water) and high-pressure fan-shaped water jets, and low-pressure brush heads can spray low-pressure water streams for gentle scrubbing.
Brands
High-pressure washer brands are divided into domestic and foreign brands. Generally, domestic washer machines are somewhat weaker in performance and quality compared to foreign ones, but domestic high-pressure washer machines are relatively cheaper. Foreign brands such as Kärcher are good choices.
