I have a 22" fsc with detachable wheels and brush ring from Merrill Fox about 2 years ago, brilliant tool, also he supplied a 4-nozzle water broom for about £18. which goes on the end of the lance. Also a great tool. The fsc is great for avoiding overspray (windows, cars, plants etc.) but because the available pressure is split between the two nozzles the force is halved and it wont get off stubborn algae etc. Turbo nozzle best for this or even ordinary one, but more mess. Water broom is great for flushing away as the pressure is then split four ways so it is more controllable. My pw was about £350 +vat & carr. (2007) from a dealer in Ireland its 3600psi, 16lpm interpump and honda lookalike 13hp pullstart.
