High-Pressure Washer
Frequently Asked Questions
What main criteria should I consider when choosing a pressure washer?
The main features are water pressure (bar), water flow rate (liters per hour), and motor power (watts). Pressure determines the cleaning force, while flow rate dictates the speed of washing away and clearing dirt.
What is the difference between household and professional pressure washers?
Professional units feature a more powerful motor, a durable metal (brass or aluminum) pump, and are designed for continuous heavy-duty use, whereas household models are relatively compact with plastic pumps, intended for periodic tasks.
What pressure is optimal for safely washing cars, patio pavers, and facades?
A range of 110–130 bar is sufficient for safe car washing, while 140–160 bar is optimal for effectively cleaning patio pavers, stonework, and building facades.
Can the pressure washer draw water from a tank on its own, or is a tap connection required?
Many modern models feature a self-priming function, allowing you to operate the unit directly from a tank or bucket without a tap connection, though using a dedicated suction filter is recommended.
What types of detergents are used in high-pressure washers?
Special low-foaming car shampoos and active foams formulated specifically for high-pressure washers are used, ensuring internal components and the pump remain undamaged.
