Device for cleaning and/or processing of surfaces, has ejection device formed such that fluid jets and/or suction and work flow are obtained, where suction and work flow is influenced by fluid reflecting surface based on low pressure

摘要

The device has a suction device supplying fluid stream (19) to an exit channel (63). Low pressure is produced by the stream by the suction device. The suction device stays in flow connection with an ejection device in order to supply fluid and material to the channel, where the fluid is reflected by the low pressure of a surface (35). The ejection device is formed such that fluid jets and/or suction and work flow influenced by the fluid reflecting the surface are obtained based on the low pressure in a workspace (41), where the fluid jets are discharged from outlet ports (37).
