In May of this year I was quoted over £40 for a replacement rotary nozzle for my 2008 High Pressure Cleaner via the Powercraft helpline. Instead, I bought a Sealey Turboblast nozzle and extension lance from The Site Box.com (total incl p&p £20.08) and a Sealey/Karcher adapter from Notion Enterprises (via eBay) for £7.69 incl p&p. The latter had to have the lugs filed down a bit in order to fit the Powercraft gun. Result was very satisfactory. Future replacement nozzles should each cost around £6.20 + p&p.
