I am looking to buy a power washer for my own use and might use it once or twice a year for one or two of my customers and have settled on the Craftsman 2500 psi Pressure Washer160cc w/ Honda GVC 160 Engine. My question is do I need to buy the turbo wand for this thing or the turbo quick connect nozzle? The wand is $39.99 and the quick connect is $49.99. I dont understand what the difference is. Can someone help me out.
