SIMPSON vs Dapper Supply Specs
Power Source
The SIMPSON PowerShot is a standalone gas-powered pressure washer. It uses a Honda GX200 engine to generate high pressure and flow. This makes it a complete unit ready for general cleaning tasks. The Dapper Supply product is not a power source. It is a surface cleaner attachment. It requires an existing pressure washer to operate. You must pair it with a machine providing 2500 PSI or higher. This means you need a separate gas or electric washer. The SIMPSON offers self-contained power. The Dapper Supply relies on your existing equipment.
Pressure Output
The SIMPSON PowerShot delivers 3300 PSI of maximum pressure. This is sufficient for stripping paint, cleaning decks, and removing graffiti. The Dapper Supply surface cleaner has a maximum pressure rating of 4000 PSI. However, this rating indicates the maximum input pressure it can handle, not its own output.
