Abstract: This hanger system for use in window balances features a hanger connected at a lower end of a window balance. The hanger has a carrier interface for connection to the window sash carrier. The carrier has a hanger interface for connection to the hanger. The interfaces are connected and disconnected by a pivoting motion of the hanger with respect to the carrier. Once connected these elements cannot be pulled apart and disconnected by tensile forces without first reversing the assembly steps. A snap connection may also be advantageously added to the hanger and carrier, allowing them to snap together in permanent or non-permanent fashion when fully or partially pivoted into alignment with each other.

Abstract: A cleaner for cleaning a surface comprises a floor-engaging portion for moving along the surface. A magnet and a hall effect sensor located in the cleaner handle generates a control signal. The control signal is provided to a control circuit which controls one or more operational features of the cleaner. One such operational features includes at least one pump for mixing and distributing cleaning solution to the surface. In an alternate embodiment, the control circuit controls an electric motor for propelling the cleaner over the surface.
