1. 135 bar 530l/h k6.91 model

2. 150 bar 450 l/h k7.85 model

what do I need more ? bar power or water flow per hour ?



Do you reccomend anything else ?
 
I work for a Karcher distributer.You can only flow so many gallons per minute from a 4 gpm tap outlet. For cleaning you want low pressure with lots of flow. Too High pressure will harm the surface
