What our Experts Think
Q&A
Q: What is the CleanFreak Softwash System (300 PSI @ 11.5 GPM) used for?
A: This skid-mounted softwash system is designed for low-pressure, high-volume cleaning of exterior surfaces like roofs, siding, fences, decks, and commercial buildings, safely removing mold, algae, mildew, and organic buildup.
Q: What makes this softwash system different from a pressure washer?
A: Unlike high-pressure washers, it uses only 300 PSI combined with high flow (11.5 GPM) to apply cleaning solution gently, preventing damage to paint, shingles, and delicate surfaces.
Q: What pump and engine does it use?
A: It runs a Comet P40 diaphragm pump paired with a 6.5 HP Vanguard gas engine with electric start for reliable field operation and chemical resistance.

A: Yes. The diaphragm pump and fittings are built to handle bleach and softwash chemicals for killing algae, mold, mildew, and bacteria effectively.

A: It comes skid-mounted, allowing it to be installed on a trailer, truck bed, or service rig for mobile softwashing operations.
Q: What kind of work is it best suited for?
A: It’s ideal for professional exterior cleaning contractors handling residential roof washing, commercial building washing, and high-volume rinse applications.
Q: Is this model still available?

Maintenance Tips
