Abstract
A disk with an engagement system for a surface cleaning machine includes a disk having an upper surface, a lower surface, a perimetric edge, and a retaining cavity defined in the disk; an engaging member having a base and a perimetric wall, which is configured to be nested in the retaining cavity of the disk and to entrain an inner wall of the retaining cavity; a first metallic member housed within the disk; and a second metallic member housed within the engaging member. The first and the second metallic members are magnetically attracted to one another with a force that is larger than the gravity force of the disk and smaller than a predetermined detaching force of the disk from the engaging member.

A disk with an engagement system for a surface cleaning machine comprising:
- a disk having an upper surface, a lower surface and a perimetric edge, the disk having a retaining cavity defined therein;
- an engaging member having a base and a perimetric wall, the engaging member being configured to be nested in the retaining cavity and to entrain an inner wall of the retaining cavity;
- a first metallic member housed within the disk;
- and
- a second metallic member housed within the engaging member,
- wherein the first and the second metallic members are magnetically attracted to one another, and
- wherein the first and the second magnetic members are selected to have a magnetic attraction that is larger than a gravity force of the disk and smaller than a predetermined detaching force.
