Cleaning — FAQ
How much PSI do homeowners actually need?
Most homeowners achieve excellent results with 3000-3500 PSI. This range cleans driveways, decks, siding, and vehicles effectively without risking surface damage. Reserve 4000+ PSI for heavy concrete restoration or frequent large-area cleaning.
Are gas pressure washers worth it over electric?
Gas models deliver 2-3x more power and true portability without cord length limits. They’re essential for large properties, remote areas, and heavy grime. Electric washers suit small patios and car washing where noise and fumes are concerns.
What maintenance is required?
Change oil after first 5 hours, then every 50 hours or annually. Stabilize fuel for storage, run pump saver antifreeze through system before winter, and inspect hoses monthly. Clean air filter every 10 hours in dusty conditions.
Can I damage my house or car with too much pressure?
Absolutely. Start with widest nozzle (40°) and test in inconspicuous area. Keep nozzle 12-18 inches from surface. Wood siding and automotive paint require under 2500 PSI at point of contact. Use detergent and let it do the work.
Does hose length really matter?
Critical for efficiency. A 25-foot hose forces repositioning every few minutes on large jobs. Thirty-two feet reaches second-story peaks and across driveways without moving the unit. Consider extension hoses for properties over 1/4 acre.
What’s the difference between residential and commercial units?
Commercial washers use triplex pumps with ceramic pistons for 2000+ hour lifespans versus 200-500 hours for residential axial pumps. They also feature higher GPM, heavier frames, and commercial engines. Homeowners rarely justify the 3x price premium.
