Pressure Washing Business input evidence register
45 financial inputs with their assumptions, calculation bases and cited sources.
Read the supported claim, observation period, geography and units together. A source access date records when it was consulted. A model assumption identifies a selected amount or target; a calculated result follows from those inputs and does not establish observed demand or a quoted opening budget.

- Model assumption
Applies to: Four GPM hot-water trailer rig
The $11,000 equipment allocation is an authored assumption. The manufacturer manual supports selected 157595 specifications; water-weight arithmetic is independent of a delivered rig price. CPSC recall 26-224, dated January 29, 2026, includes specified batches of item 157310, 157594 and 157595. Screen both the product serial and burner code against the recall, and confirm the authorized remedy for an affected unit. Current price, tax, freight, assembly, tow suitability, actual unit condition and completed repair remain unverified.
- Model assumption
Applies to: Soft-wash system, surface cleaner, hoses, reels and accessories
The accessory allocation is an authored bundle requiring a delivered specification and price list. Linked component pages are procurement context; their current prices and availability were not independently verified in this remediation.

The recovery and wastewater-control allocation is authored. Portland and Orlando provide bounded local handling context; neither verifies a nationwide compliant equipment package, the selected amount or permission for the intended job.
