Spend some time on autopia.com.

In my experience the electrics will be marginal for you needs ( especially for the drive way). Also they are very noisy also. Finally, with moderate use expect no more than five years. I would get from Sams and keep the receipt because of the " no questions" return policy

I use a semi-pro (prosumer) gas model and it is very versatile and use it for everything.

I am not a big fan of using a pressure washer on a dirty car. It is not that far off from sand blasting your clear coat. I bought a CR Spotless which allows me plenty of pressure (hose line only) to wash my car and allows me to utiulize the filtration and de-ionization. Worls like a dream.

I agree on all counts. It was sort if understood on my part that the pressure would only be used on the undercarriage and wheel wells.

The other use is with a foam cannon.
