Abstract
A battery powered floor maintenance machine is alignable with a battery docking station that can slidably receive a spent battery assembly from the floor maintenance machine. The floor maintenance machine includes locking and aligning mechanisms to safely attach the machine to the docking station. Once attached, the battery assembly is slid onto the docking station for recharge. The floor machine can be removed from the docking station and attached to a second charging station with a fully charged battery assembly thereon. The battery assembly can be slid from the second charging station to the floor maintenance machine, allowing the machine to be returned to service.
