hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahah WHEEeeeew and hahahahahahahahahaha,lol,when it depends,I've own two different kinds in my life time,they not for fleetwashing,nothing beats the old hand model for speed......why you getting lazy too.
Two step it man forget about the rotating brush even the old hand model too.If you try one don't shot all the psi at once,pull the trigger slow or you'll tear the gears out of the head and made SURE your not useing hotwater or it will melt the gears in the head,I've own both models,still have a new one in the shop that newbee's want to buy but I make up a long story as to not to gave it away but truth is its a reminder to stop wasteing my money.I'm sure it depends on what your wanting it for but its not for speed in the fleetwashing field.
