Abstract
A floor care method and machine are disclosed, wherein a replaceable floor care element (e.g., a cleaning pad, a brush, a polishing pad, etc.) is easily attached to and detached from the rest of the machine. For attaching the floor care element, an operator positions the machine (minus any floor care element) over the such an element so that components on the machine and/or the floor care element cause the floor care element to operationally align with the rotatable drive of the machine so that rotation of the drive in the direction used during floor care operations causes the floor care element to securely attach to the drive. Alternatively, to detach the floor care element, the direction of rotation can be reversed. The machine can then be tilted upwardly onto its rear wheels and rolled to a location where the floor care element is not underneath the rest of the machine.
