Abstract: The invention relates to a cleaning machine (1) comprising a housing (10) and at least one hingeable element (20), as well as to the hingeable element (20) itself. The hingeable element (20) is detachably attachable to said housing via a hinge structure comprising at least two pairs of magnetizable or magnetic member surfaces (H1, E1; H2, E2). At least one surface in each pair exhibits a magnetic force for engagement with the other surface in said pair. A first member surface (E1; E2) in each of said pairs is supported by said hingeable element (20) and a second member surface (H1; H2) in each of said pairs is supported by said housing (10). When said hingeable element (20) is attached to said housing (10), said magnetic force is extending in a direction substantially in parallel with a magnetic centre axis (Am) extending between each first member surface (E1; E2). This provides a sufficient attachment force in the hinge structure both to allow the hingeable element (20) to stay attached to the housing during use, as well as to allow the hingeable element (20) to become detached easily from the housing (10), thus to function as a “break away”.
