Honestly you're going to need Gas if you want to quickly clean concrete. This one will work on concrete will just take longer - the kobalt turbo head works well on concrete, and that one is 1700/1.2chrislim604 wrote: ↑ How much PSI / GPM would you feel comfortable with for cleaning concrete? I'd rather not deal with gas if I could so electric would be ideale.. suggestions on models would be appreciated.
You'll want 2-3k psi and 2.5+ gpm to clean concrete efficiently and effectively, and you pretty much can't get that from electric. But, if you're doing your driveway once a year, electric will do.
