Abstract
An automated building washing device generally includes one or more rotational brushes having a vertical rotational axis coupled to a window washing swing stage. The brushes are horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while rotating about their vertical axis so that a relatively large portion of building surface can be quickly cleaned.
Claims16
An automated building washing apparatus, comprising:
- a swing stage;
- a frame coupled to the swing stage;
- a first track coupled to the frame;
- a second track coupled to the frame;
- a first brush rotationally coupled to the first track such that a rotational axis of the first brush is in a vertical axis and that the first brush can move horizontally between opposing longitudinal ends of the first track while rotating about the vertical axis;
- and
- a second brush rotationally coupled to the second track such that a rotational axis of the second brush is in the vertical axis and that the second brush can slide horizontally between opposing longitudinal ends of the second track while rotating about the vertical axis.

An automated building washing assembly that can be retrofitted to a swing stage, the automated building washing assembly comprising:
- a frame adapted to be coupled to the swing stage;
- a first track coupled to the frame;
- a second track coupled to the frame;
- a first brush rotationally coupled to the first track such that a rotational axis of the first brush is in a vertical axis and that the first brush can move horizontally between opposing longitudinal ends of the first track while rotating about the vertical axis;
- and
