fair enough... It is great!! lol and to be honest would easily cope with 90% of the stuff I have been asked to do. However the one job I picked up as an add is enormous with parking for 30 cars minimum and he wants it twice a year and is willing to pay so it makes sense to get something bigger... At the time I thought his would be a one off, but its come up really well... I bought the turbo nozzle and flat surface cleaner separately which also helped
