Riding apparatus for treating floor surfaces with a power cord handling swing arm

An electric powered riding apparatus for treating a floor surface and having a motorized vehicle and a power cord extendable from said apparatus to an electric source, said apparatus comprising:

• a jointed swing arm having a proximate arm member with a pivotable connection about a vertical axis to said vehicle in proximity to a longitudinal center line of said vehicle and a distal arm member pivotably connected about a pivot vertical axis to said proximate arm section and having a retainer for mounting said power cord;
• said distal arm member being resiliently biased to extend straight out with respect to said proximate arm member;
• said swing arm dimensioned to extend said distal arm section beyond a side of said vehicle when said swing arm extends laterally with respect to said vehicle;
• and
• a spring member connected to said distal arm member for resiliently biasing said distal arm member to extend straight out with respect to said proximate arm member against a side force below a predetermined amount and yieldable to allow bending of said distal member with a side force above said predetermined amount.
