Heavy-Duty Pressure Washer: How They Work, Common Problems, and Repair Solutions

Heavy-duty pressure washers are robust machines designed for intensive cleaning tasks, including commercial, industrial, and large-scale residential applications. They are widely used for cleaning stubborn grime, grease, and dirt from surfaces like driveways, heavy machinery, and building exteriors. Proper maintenance and timely repairs are crucial for ensuring their efficiency and longevity, especially for users seeking Heavy-Duty Pressure Washer Repair in Nairobi.

How Heavy-Duty Pressure Washers Work

A heavy-duty pressure washer uses high-pressure water to clean surfaces effectively. Here’s a breakdown of how it operates:

1. Water Supply: Water is drawn from a source (e.g., a tap or tank).
2. Pump Mechanism: A high-pressure pump pressurizes the water, often increasing it to 2,000–4,000 PSI (pounds per square inch).
3. Heating System (if applicable): Hot water pressure washers heat the water using a burner for more effective cleaning of grease and oil.
4. Nozzle Delivery: The pressurized water is delivered through a hose and nozzle, which can adjust the spray pattern for specific cleaning tasks.
5. Cleaning Agents (Optional): Some models allow the addition of detergents for enhanced cleaning.
