<p>Filter device for a vacuum cleaner apparatus, comprising a water accumulation container (18) into which primary air is introduced, sucked in by a motor (15) through a suction pipe (19). The filter device also comprises an introduction pipe (50) to introduce a fluid which encourages the dust (20) to fall into the container (18) and a second introduction pipe (34) arranged downstream of the first introduction pipe (50). The second introduction pipe (34) is able to introduce secondary air into the water contained in the container (18) to create a spray of water (46) onto the dust (20) sucked in and introduced together with the primary air and already hit by the fluid.</p> |
