After a wee while without any major mishaps (just your usual daily woops moments ! ) i struck again! I had just bought a longer lance to help with a sore back and was happily PW a driveway and path and as i turned around i managed to clonk the turbo head (minus rubber protective cover as keeps falling off ! ) right up the customers window sill taking a bit chunk right out of it. This was with no pressure or water just the head hitting off the sill as i had forgotten about the longer lance ! Customer was cool about it and loved a bit of DIY so got off lightly on that one !
