<p>A vacuum cleaner, especially for cleaning high-precision mechanical or electronic modules and apparatuses, has a jet pump (9) for generating a vacuum to suck up a liquid, a feed-air line (6) to supply compressed air to the jet pump as well as a drain line (7) to conduct away the sucked-up liquid plus a handle (2) for the operation of the vacuum cleaner. The jet pump is accommodated in the handle. The jet pump is accommodated in the region surrounded by the hand of an operating person during the operation of the vacuum cleaner. The center of gravity of the vacuum cleaner disregarding the feed and drain lines lies in the region surrounded by the hand of the operating person.</p> |
