Abstract: A cleaning machine for cleaning surfaces, including a support frame holding a rotary cleaning organ to clean the desired surface, first rest for the support frame, auxiliary rest wheel of the support frame movable into assume first and second positions in which it is raised and lowered, respectively, the auxiliary wheel being positioned at a base of a stem slidable in a bushing associated to the support frame with the axis perpendicular to the support frame between a first raised position and a second lowered position. The stem includes a groove defined on a surface thereof and the bushing includes a pin projecting internally thereof and able to slide in the groove. The groove includes first and second upper cusps proximal to the end of the stem that is distal from the wheel, the first and second upper cusps being alternated with first and second lower cusps directed towards the end of the stem proximal to the wheel.

Abstract: A pump assembly 10 for high pressure cleaners having a pump body 12 encasing the free end 14 of a motor shaft provided with a keyed-on wobble plate 16 which moves one or more than one axial pistons 18 that are elastically tensioned by helical springs 20. The pump assembly also includes a pump head 32 fixed to the pump body 12 provided with fluid inlet and outlet conduits and relative valves, and an intermediate housing 34 for receiving and guiding the piston 18. The intermediate housing 34 has a frustoconical-shaped body with its larger diametered bottom section facing the same-diametered pump body 12 and being secured thereto by screws 36.

Abstract: An improved pump assembly 10 for high pressure cleaners, comprising a pump body 12 encasing the free end 14 of a motor shaft provided with a keyed-on, wobble plate 16 which moves one or more than one axial pistons 18 that are elastically tensioned by helical springs 20; the improved pump comprising also a pump head 32 fixed to said pump body 12 provided with fluid inlet and outlet conduits and relative valves, further to an intermediate housing 34 integrating the piston 18 support and guide lodgings.

Abstract: A floor-cleaning machine comprising a support frame (2) which is mobile on a floor, on which support frame (2) are installed at least a rotating cleaning organ (50) which can be in contact with the floor, and a motor (51) to draw the cleaning organ (50) in rotation, the rotating cleaning organ (50) comprising a cleaning element (53) made of microfibre, which is destined to come into direct contact with the floor.

Abstract: A floor-cleaning machine comprising a support trolley (2), on which support trolley (2) at least a floor-cleaning group (7) is installed, which floor-cleaning group (7) is provided with at least a flexible blade (70) and is mobile on board the support trolley (2) between a work position, in which the flexible blade (70) is in contact with a floor, and a rest position, in which the flexible blade (70) is distanced from the floor, the floor-cleaning machine comprising magnetic means (26) which are destined to block the floor-cleaning group (7) in the rest position.
