The general consensus is to move up from a 4GPM machine to a 5.5GPM machine. The 4GPM ones you’re looking at will work and absolutely make you money. But GPM is king. Most washing is less than 3K psi even for flatwork. What is your budget and what are you washing?
Ready to run rig:
BE Pressure Washer 5GPM/ 3000PSI from PWRA
Build your own with a Honda GX390 $799 or Predator 420 $369 and a gear drive pump TSB-5638G ALLISON $449 with gearbox installed.
You can also call Russ at Southside (502) 504-5454 for a belt system if you want to build that yourself vs a gear drive. Belt drive skid $141 or aluminum skid $83
You also need an unloader Pulsar $64 or K7 and an unloader block $32
Are you comfortable building your own and plumbing a buffer tank since using a 5.5 gear or belt drive you need a 35-65GPM (your preference)
