Measured in pounds per square inch (PSI).
Different surfaces require different pressures:
Low PSI (1,000–1,500) for delicate surfaces like wood or painted walls.
High PSI (2,500–4,000+) for concrete, driveways, or heavy buildup.
Measured in gallons per minute (GPM).
A higher GPM means more water is used to rinse away debris, improving cleaning speed and efficiency.
Knowing what you’re cleaning (e.g., brick, concrete, wood, tile, metal) determines the right pressure, nozzle, and detergent.
Using the wrong settings can cause damage or ineffective cleaning.
Many jobs require chemical agents for removing oil, algae, mildew, or grease.
Eco-friendly options are essential for environmental safety, especially near landscaping or water sources.
Hot water is more effective at removing oil, grease, and sticky residue.
Cold water is sufficient for general dirt and dust removal.
Different nozzle angles (0°, 15°, 25°, 40°) control spray width and intensity.
Narrower for deep cleaning.
Wider for gentle rinsing.
Proper gear: gloves, goggles, non-slip boots.
Knowledge of how to safely operate machinery to avoid injury or property damage.
Consider ease of access to the area being cleaned.
Fully mobile units (like JMC’s vans) provide an edge for off-grid or remote jobs.
Runoff management and chemical disposal must comply with local environmental laws.
Skill in maintaining even pressure, distance from the surface, and overlap ensures a clean, streak-free result.
PSI (Pounds per Square Inch): Measures pressure.
1,300–2,400 PSI = Good for homes, fences, patios.
2,400–3,000+ PSI = For tougher jobs like driveways.
GPM (Gallons per Minute): More GPM = faster rinsing.
🛑 Too much pressure can damage siding, paint, or wood. Always test first!
Choose settings and nozzles based on the surface type:
| Surface | Recommended PSI | Notes |
|---|---|---|
| Wood Deck | 1,300–2,000 | Use wide spray tip (25–40°) |
| Vinyl Siding | 1,300–1,600 | Clean downward to avoid leaks |
| Concrete Drive | 2,500–3,000+ | Use narrow nozzle (15–25°) |
| Brick/Masonry | 2,000–2,500 | Check for cracks before washing |
Color-coded tips affect spray power:
| Color | Degree | Best For |
|---|---|---|
| Red | 0° | Spot cleaning tough stains (use cautiously!) |
| Yellow | 15° | Concrete, brick |
| Green | 25° | Decks, siding, patios |
| White | 40° | Rinse and delicate surfaces |
| Black | 65° | Soap application |
Use biodegradable cleaners that are safe for pets, plants, and kids.
Pre-soak surfaces for better results.
Rinse thoroughly to prevent residue buildup.
Wear goggles, gloves, and non-slip shoes.
Never point the nozzle at people, pets, or windows.
Keep the hose away from electrical outlets.
Tip: Maintain 12–18 inches between the nozzle and the surface to avoid damage.
Hot Water: Better for grease/oil removal.
Cold Water: Ideal for general dirt, dust, algae.
Avoid power washing during wind or rain.
Let surfaces dry properly after cleaning (especially before painting or sealing).
Flush out detergent after each use.
Store hoses and nozzles properly.
Winterize the machine if storing long-term.
Work top to bottom, left to right.
