looking for pesticide type sprayer suggestions

[yas]

Hi



Any suggestions for a pump / pesticide sprayer that generates good enough pressure to remove dirt before washing?



I'm starting to use ONR for washes, I like not having to be at home to do the wash



I still like to do a presoak and rinse, probably not the whole car but a few areas. Curious if there is a pesticide / pump sprayer designed for generating maximum pressure, preferably something small , 1 or 2 gallons

None of the ones I've used would generate enough pressure to actually remove any dirt.
