Ive had loads of different machines when i was a mobile valeter
All shite and unreliable apart from my last petrol one
Cheap petrol ones just fuck up and the pumps always pack in no matter what
Honda Cobra 160, i then built a custom twin lance for soap and pressure with side ajuster and was the best i ever had, wish i never sold it now tbh
Karcher seem very cheaply made compared to many years ago
Buy a cheapy and replace it every year kev if need be
