Simpson Softwash Skid — CRX225 & Comet P40
$1,599.00
A Simpson softwash skid pairing a CRX225 engine with a Comet P-40 diaphragm pump, built for roof cleaning and house washing applications.
Softwash is a different discipline than pressure washing. Instead of using pressure to blast contamination off a surface, it applies cleaning solution at high volume and low pressure and lets the chemistry do the work. That's what makes it the correct method for asphalt shingle roofs, painted siding, stucco, and any substrate that high pressure would damage — and it's why softwash systems use diaphragm pumps rated around 300 PSI rather than the 3000+ PSI triplex pumps found on surface cleaning rigs.
The CRX225 provides commercial-grade power at a lower cost than premium engine options, making this a practical entry point for contractors adding dedicated softwash capability. The Comet P-40 at the core is the same pump used across the professional softwash market, with full parts availability.
