Is an entry-level soft wash unit enough for my business?
For a crew starting or adding house washing, roof cleaning and deck work, yes. You supply the tanks, hose and proportioning. If you want a turnkey skid with tanks, reels and a mixer included, step up to the Mini Tsunami ($6,195) or the full Tsunami soft wash skid ($8,795).
Soft wash vs. pressure wash: when do I need each?
Soft washing uses low pressure and cleaning solution for surfaces that high pressure can damage, like shingles, siding, painted wood and screens. Pressure washing is for concrete, equipment and hard surfaces. Many contractors run both. See soft wash and pressure wash combo units.
Frequently asked questions
What PSI is a soft wash system?
The CSW Soft Wash Series runs at 300 PSI with 11 GPM of flow, which is low enough for roofs and siding while still moving plenty of solution.
Honda or Mi-T-M engine?
Both are OHV gas engines. The Mi-T-M models cost less; the Honda GX200 models are a familiar choice for crews that already run Honda engines.
Can I buy a CSW unit in California?
Gasoline models sold in California require a CARB compliant engine. Call us before ordering so we can confirm the right engine.
