It cleans dirt off my cement drive way much better. It also reaches the second story windows of my house with more pressure and more volume. 3.5 gal is always more water than 2.5/min.
I was in sams and saw three pressure washers were they they sell the open box specials and such. All were the 13hp hondas. Two were the new models of this year for $99 and 1 was the model they sold last year or the year before for $20. None had hoses. I bought the three. Two worked good after I put new pull cords on them and the third I couldn't start. I gave two to my father and he gave the one we couldn't start to his mechanic buddy. A new 50' 3/8" hose and gun and tips and some pump oil and regular oil cost about $120. So it was a good deal.
I can probably find the receipt if you don't believe. I posted a pic of my mowing equipment and people don't believe that either...
