Drive coupler for power scrubber

A power scrubber comprising:

• a shaft extending along a shaft axis between a first end and a second end, the shaft including a first portion and a second portion, the second portion movable relative to the first portion in a telescoping manner to adjust a length of the shaft along the shaft axis;
• a power receptacle configured to receive power from a power source, the power receptacle being positioned adjacent the first end of the shaft;
• a handle positioned adjacent the first end of the shaft;
• a power head including a motor receiving power from the power source, the power head positioned adjacent the second end of the shaft;
• a pivot coupling that couples the power head to the second end of the shaft, the pivot coupling operable to adjust an angle of the power head relative to the shaft axis;
• a first scrubber head including a body having bristles;
• a second scrubber head including a body having bristles;
• and
• a drive coupled to and driven by the power head, the drive extending along a longitudinal axis, the drive including
• a first connector configured to selectively engage the first scrubber head such that a center of the first scrubber head is aligned with the longitudinal axis, the first connector connected to the first scrubber by a bayonet coupling, and
• a second connector configured to selectively engage the second scrubber head such that a center of the second scrubber head is aligned with the longitudinal axis.
