Understanding PSI vs GPM
Before buying equipment, understand these two critical specs:
PSI (Pounds per Square Inch)
Determines cleaning power—how tough the grime you can remove.
- • 2,000-2,500 PSI: Light residential
- • 2,500-3,000 PSI: Standard residential
- • 3,000-4,000 PSI: Heavy residential/commercial
- • 4,000+ PSI: Industrial/concrete
GPM (Gallons per Minute)
Determines cleaning speed—how fast you finish jobs.
- • 2.0-2.5 GPM: Hobby/light use
- • 2.5-3.5 GPM: Entry professional
- • 4.0-5.5 GPM: Professional standard
- • 5.5+ GPM: High-volume commercial
Pro Tip: GPM matters more than PSI for most jobs. A 4 GPM machine at 3,000 PSI will outperform a 2.5 GPM at 4,000 PSI in speed and efficiency. Time is money.

Seasonality & Cash Flow
Plan for seasonal fluctuations:
- Peak Season (March-June): Highest demand. Book 4-6 weeks out.
- Summer: Steady demand. Hot weather affects work hours.
- Fall: Second peak before holidays. Gutter cleaning upsells.
- Winter: Slow in cold climates. Focus on commercial or indoor work.
Tip: Southern states (TX, FL, AZ) can work year-round. Northern states should plan for 3-4 slow months or offer complementary services like window cleaning or holiday lighting.
