FOD on ramp

[Headwind]

Looking at buying something to vacuum our ramp area. In the past we use a water hose and wash or a blower to blow away very small gravel. After we get the area clean a King Air or Cheyenne will taxi by and blow this back on our ramp, even in our hangar if the door is open.
Looking at machine called Billy Goat with 5 HP Briggs engine. Anyone use this machine or another with good results?

We have one at the hangar in Knoxville, (TYS). Works fairly well on the ramp and in the parking lot, leaves and cigarette butts are no problem, neither are nuts, small bolts, safety wire snivettes and the such. We don't even take real good care of the engine, just fire it up and go. Been that way for five years now.
