Claim 8

The machine according to claim 1, wherein said air generating means for generating a secondary air stream are connected, through tube branches, to said at least one Venturi duct which is provided in said water container to a side of the outlet of the end portion of the dirt suction duct.

Claim 9

The machine of claim 7, wherein two Venturi tubes are provided, arranged diametrically opposite with respect to said end portion of the dirt suction duct.

Claim 10

The machine according to claim 8, comprising, at outlets of said Venturi ducts, nozzles for nebulizing the aspirated water.

Claim 11

The machine of claim 1, further comprising, located in said box shaped body, a steam section.

Claim 12

A machine for household cleaning comprising: a box shaped body including a vacuum-cleaner section; a fan for generating a main air stream; an electric motor coupled to said fan, the fan and the electric motor being located in said vacuum-cleaner section; a water container hermetically closed by a cover; a dirt suction duct, being connected to an intake of said fan, and having and end portion with an outlet thereof located in said water container inside a dome protruding downwardly from said cover; at least one Venturi duct, for aspirating water from the water container, which ends in a region where said main air stream passes so as to wet and remove the dirt contained in said main stream; air generating means, provided in said body upstream of said fan, for generating a secondary air stream, in said at least one Venturi duct, which is separate from the main stream that contains dirt; an upper duct portion, connected to the intake of the fan, and ending downwardly at the internal upper part of said water container, with a vertical coupling thereof; a floater for interrupting said vertical coupling; a grilled containment element for retaining said floater, with said floater having a closure level being lower than the outlet of said end portion that lies inside said container; and a removable partition being arranged between said dome and said grilled containment element to increase air flow convolution inside said water container.

Claim 13

A machine for household cleaning comprising: a box shaped body including a vacuum-cleaner section; a fan for generating a main air stream; an electric motor coupled to said fan, the fan and the electric motor being located in said vacuum-cleaner section; a water container hermetically closed by a cover; a dirt suction duct, being connected to an intake of said fan, and having and end portion with an outlet thereof located in said water container inside a dome protruding downwardly from said cover; at least one Venturi duct, for aspirating water from the water container, which ends in a region where said main air stream passes so as to wet and remove the dirt contained in said main stream; air generating means, provided in said body upstream of said fan, for generating a secondary air stream, in said at least one Venturi duct, which is separate from the main stream that contains dirt; an upper duct portion, connected to the intake of the fan, and ending downwardly at the internal upper part of said water container, with a vertical coupling thereof; a floater for interrupting said vertical coupling; a grilled containment element for retaining said floater, with said floater having a closure level being lower than the outlet of said end portion that lies inside said container; and a removable partition being arranged between said dome and said grilled containment element to increase air flow convolution inside said water container.

Claim 14

The machine according to claim 11, wherein said air generating means for generating a secondary air stream is constituted by a discharge of said fan.

Claim 15

The machine according to claim 11, wherein said air generating means for generating a secondary air stream is constituted by a secondary fan that is separate from the fan for generating the main air stream, and wherein a further electric motor is provided coupled to said secondary fan.

Claim 16

The machine according to claim 11, wherein said water container closed hermetically by the cover is accommodated in an adapted compartment of said box shaped body.

Claim 17

The machine according to claim 11, wherein said end portion of said suction duct is vertical.

Claim 18

The machine according to claim 12, wherein said air generating means for generating a secondary air stream are connected, through tube branches, to said at least one Venturi duct which is provided in said water container to a side of the outlet of the end portion of the dirt suction duct.
