The Simpson ALWB60825 is a belt-drive aluminum-frame gas pressure washer built for the kind of daily commercial duty that cooks direct-drive units in a season. The CRX420 engine and AAA triplex pump are belted instead of direct-coupled, which lets the pump turn at its design speed (not engine speed) and keeps both engine and pump running cooler under all-day load.

- Concrete cleaning: restoration of driveways, sidewalks, and parking lots at 4400 PSI
- Fleet and equipment wash: trucks, trailers, mowers, and farm equipment
- Construction cleanup: rinsing concrete forms, post-pour cleanup, and site walls
- Industrial and food processing: exterior surfaces and equipment between shifts
- Exterior cleaning contractors: mid-day commercial work where a belt drive holds up

Frequently asked questions
Why pay for a belt drive over a direct drive?
A direct-drive pump runs at engine speed; a belt-drive pump runs at the pump's design speed and at lower temperatures. For daily commercial duty over years (not seasons) the belt drive is the longer-life choice.
Does it have a Honda engine?
No. The ALWB60825 ships with a CRX 420cc engine. The closely related ALWB60827 and ALWB60828 ship with Honda GX390 engines instead. Pick by engine preference and parts availability in your area.
Will it freight ship to a residential address?
Yes, but a residential delivery without a forklift will need a liftgate. Confirm liftgate at order time and have someone available to receive the freight.
Can I run a surface cleaner with it?
Yes. 4 GPM is the minimum flow for most 16-20-inch surface cleaners. The aluminum frame and pneumatic tires let you walk it across concrete behind a surface cleaner without dragging.
