Pressure Washer Surface Cleaners — 19" to 30"

A surface cleaner is the fastest money you will make on flatwork, provided the deck matches the machine. This is the single most common mistake we see: someone buys the biggest deck they can afford, hangs it off a 4 GPM machine, and then cleans slowly and leaves stripes.

Rough pairing: 4 GPM runs a 19 or 20 inch deck. 5.5 GPM runs a 24. Eight GPM or better earns the 28 and 30 inch decks. If you are between sizes, go smaller — an undersized deck is slow, an oversized deck is slow and streaky.
