High-pressure cleaning device.
1. A high-pressure cleaning apparatus with an internal combustion engine (1) which, via transmission means, drives a high-pressure pump (3) whereby a cleaning fluid is delivered under pressure to a spray device (33), characterised in that the high-pressure pump (3) is arranged on the engine (1) in such a way that the output shaft (2), or an extension thereof, of the internal combustion engine (1) projects into the housing (4) of the high-pressure pump (3) ; in that a gap (6) is present between the internal combustion engine (1) and the pump housing (4), and in that a belt pulley (17), non-rotatably connected to the output shaft (2) of the engine, is arranged in this gap (6), which pulley drives an electrical generator (21) via a transmission belt (18).
