Cleaning machine (100) comprising a nebuliser device (10) for nebulising a liquid product (115), a tank (110) containing said liquid product (115), an intake part (120) comprising at least one waste air vent (125), wherein said nebuliser device (10) comprises a dispenser (20) for dispensing said liquid product (115), a first connecting duct (211) which connects in fluid communication said tank (110) with said dispenser (20), a second duct (225) which connects in air-flow communication said at least one waste air vent (125) of said intake part (120) with said dispenser (20), wherein said dispenser (20) comprises a hollow body (21) comprising an inner cavity (25) connected in air-flow communication with said second duct (225), a dispensing tube (30) connected in fluid communication with said first duct (211), wherein a space is provided forming a nebulisation area (40) arranged at a mouth of an outlet pass-through opening of said dispensing tube (30) and at a mouth of a pass-through outlet opening of said inner cavity (25).

An ultraviolet (UV) sterilization lighting system includes a plurality of arrays of UV sterilization lighting and a power source. The arrays of UV sterilization lighting are configured in a modular arrangement in electrical communication with the power source and enable plug-in type completion of electrical communication within the arrays. The arrays are configured in a pattern to effect desired sterilization via the UV sterilization lighting. The array formations include straight and/or curved lines, circles, triangles, squares, rectangles, pentagons, hexagons and other similar polygonal or other geometrical arrangements, whether in an ordered or disordered pattern, that are deemed most suitable to affect the desired sterilization.

A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.
