Tool for treating overhead surfaces

A tool for treating overhead surfaces comprising:

• an elongate member, wherein an inner end of the elongate member is disposed longitudinally opposite an outer end of the elongate member;
• a drive motor positioned at the outer end of the elongate member;
• a counterweight positioned at the inner end of the elongate member;
• a head comprising a bearing block and a pair of arms parallel to one another, proximal ends of the pair of arms fixed to the bearing block,
• the bearing block carrying a rotary agitator mounted to rotate about an agitator axis parallel to the pair of arms,
• the rotary agitator having a generally planar face that is configured to be applied against an overhead surface being treated in use;
• a hinge that connects the outer end of the elongate member to the head and comprises first and second coaxial bolts transverse to the elongate member and fixed in distal ends of the pair of arms;
• a shaft-receiving space that extends axially between the pair or arms and the coaxial bolts;
• a flexible shaft that extends axially from the drive motor through the shaft-receiving space to the rotary agitator for transmitting torque from the drive motor to the rotary agitator while accommodating a relative inclination of the agitator axis caused by a pivot motion of the hinge;
• a camera coupled to the head for capturing images of the overhead surfaces and generating image data, and
• a communications device that receives and transmits the image data.
