A 12v pump system is unlikely to get the job done with the DualForce
It needs a small pressure washer
What size pressure washer is required?
A small pressure washer is required to operate the DualForce 25 Solar Brush.
Although the brush itself operates at approximately 600 to 800 PSI at the brush, it should be supplied by a pressure washer with enough flow and pressure to power the system properly.
Recommended Pressure Washer Size
The recommended pressure washer size is:
- 3.0 to 3.2 GPM
- 2800 to 3300 PSI
- 11 to 12 LPM flow rate
- 190 to 225 BAR pressure range
- Maximum water temperature: 104°F / 40°C
For best performance, use a small commercial pressure washer rated around 3.0 GPM at 3000 PSI.
What is the minimum pressure washer size?
The bare minimum recommended pressure washer size is:
- 2.7 GPM
- 2500 PSI
A pressure washer below this range will not provide enough water flow or pressure for proper brush performance.
