Frequently Asked Questions

What's the main difference between a P40 skid and your Soft Wash Box?

If you want more power, higher flow, and the ability to shoot higher, go with a gas-powered Comet P40 on a Bandit skid. Itā€™s ideal for commercial and larger residential jobs where you need to hit tall roofs and cover big areas efficiently.

The Soft Wash Box uses electric-powered pump and is quieter, more affordable & easier to troubleshoot. It is great for smaller residential work, but it wonā€™t shoot as high or far, and itā€™s slower for big jobs.

What about the Comet P40/20-GR pump onlyā€”why would I buy just the pump?

The Comet P40/20-GR is just the pump head with gear reduction (no engine, no skid). Itā€™s perfect if you already have an engine you want to pair it with, or youā€™re building your own soft wash rig and want to customize your setup while saving cost.

Can I use the Delavan electric pump for roof cleaning?

Technically, yes, but itā€™s not ideal for tall or steep roofs. It works well for house washing, fences, and small residential roofs, but it wonā€™t match the reach and speed of a Comet P40 gas skid for larger or commercial jobs.
