US Patent 10590593 Lint cleaning assembly for a dryer appliance

A lint cleaning assembly for a dryer appliance includes a vacuum aperture defined in a cabinet of the dryer appliance to allow a robotic vacuum cleaner to drive into the cabinet. A lint filter collects lint within a trap duct during operation and a lint collection duct extends from the trap duct to a vacuum docking station. The vacuum docking station is positioned within the cabinet for docking the robotic vacuum cleaner, fluidly coupling the robotic vacuum cleaner to the lint collection duct for lint removal, and/or charging the batteries of the robotic vacuum cleaner.
