A: Yes, but that’s the least of your worries. The Streaks left by this unit will haunt you. This unit is best used in conjunction with a surface cleaner as a dirt pusher. I like having the unit around it has it’s good points. I also find it best used with two people. One to clean, the other to pull the hose back out or your way when you go back and forth. 13 old son works best!
A: Dragon Slayer, yes it comes with two plugs and three sprayer nozzles.
A: No, the pressure on unit is not adjustable.
A: You cannot physically adjust the water pressure on the unit. However, you can adjust the water pressure on your actual power-washer. The only way to adjust the water pressure at the surface washer is to tilt it back towards yourself and widen the spaying pattern.
