<p>The vacuum cleaner has a container to receive the collected material, fitted with a vertical side wall with a top end provided with a horizontal closure cover. The cover has two apertures (101, 102) for feeding air out of the container, one of which is connected with the inlet side for the air feed and the atmosphere outside the cleaner, and the other with the feed outlet side and the atmosphere. The apertures adopt a tipped position relative to the container side wall, forming an acute angle with the cover. This angle is selected to lessen the flexing of the hose attached to the apertures.</p> |
