Problems solved by technology

[0005] The disadvantage of the above disclosed vacuum cleaners is that although they are able to generate a large vacuum, they cannot suck with a large air flow, unless the multi-stage suction element is mounted with a very powerful and therefore very expensive drive motor

Abstract

A suction apparatus comprises a first suction device (5) having a first suction opening (6), a second suction device (20) having a second suction opening (19) and a switching device (18); the switching device causes that the suction apparatus (1) can alternatively adopt a first operation configuration (A) and a second operation configuration (B); wherein, the first suction opening (6) and the second suction opening (19) at the first operation configuration (A) are connected to the suction element of the suction apparatus (1); the suction apparatus is used for mutually acting with the suctioned material; the first suction opening (6) at the second operation configuration (B) is connected to the suction element; the second suction opening (19) is connected to the discharge outlet (22) of the first suction device (5).

Description

technical field [0001] The invention relates to a suction device, in particular a domestic or industrial vacuum cleaner for suctioning dry or liquid material from surfaces such as floors, furniture, decorative elements or the like. Background technique [0002] Known vacuum cleaners comprise a plurality of suction elements, such as a plurality of fans, each driven by a corresponding motor. Each suction element includes a suction port through which air is drawn to create a vacuum relative to the external environment. The suction openings of all suction elements are connected to the same suction pipe of the vacuum cleaner. The flow rate of airflow that the vacuum cleaner is able to suck is substantially equal to the sum of the airflows of the individual suction elements minus the head loss. [0003] A disadvantage of the vacuum cleaners disclosed above is that although they can suck a large air flow they cannot generate a large vacuum. [0004] Vacuum cleaners are also know...
