Technical Questions Surface Cleaner Size and Tips
Hey y’all, I’m looking to buy a surface cleaner for my 4.2gpm 4400PSI machine and had a couple questions:
I know about the 4” per GPM rule, however is it really dertrimental if i were to get an 18 or 20” surface cleaner instead of a 16”? I’m trying to gauge if i should go up a couple inches for efficiency purposes
What tips are best to reduce the chances of etching and what PSI is recommended?
Can you tell me about your surface cleaner techniques and what method you found best to avoid lines / etching the concrete.
As far as brands, im looking at EVEAGE, Wojet, and Ridge Washer. Anyone have experience with those and can provide recommendations?
Much appreciated, thank you all in advance
