The invention concerns a vacuum cleaner including an internal structure with a motor (12a) driving an air sucking turbine (12) located in a downstream chamber (16) communicating with an upstream chamber (15) containing means (13, 26) for filtering the air sucked in through an air intake (24). The internal structure is enclosed in an inflatable peripheral structure (30) supplied with air through the air outlet (29) of the downstream chamber (16). The inflatable peripheral structure (30) is delimited by a flexible peripheral wall (32) whose envelope completely encloses the assembly of the vacuum cleaner internal structure. The invention is applicable to vacuum cleaners for household refuse, and provides at an inexpensive and efficient protection against collisions between the vacuum cleaner and surrounding objects.
A vacuum cleaner for household refuse comprising an internal structure having means for aspirating air laden with household refuse via an air inlet, means for filtering the aspirated air and retaining the household refuse that it contains, means for evacuating the filtered air via at least one air outlet, and an inflatable peripheral structure supplied with air via said air outlet, wherein the inflatable peripheral structure is delimited by at least one flexible outside peripheral wall the envelope of which entirely surrounds all of the internal structure of the vacuum cleaner comprising the air suction, filter and exhaust means,
