A method and apparatus for determining presence of an object to be tidied in a washroom. A beam is supplied to a surface of the washroom at a first location. A reflected beam received from the surface of the washroom or received from an object in the path of the beam to the surface is detected. The presence of the object is determined from feedback from the beam based on a comparison of the feedback with a detection result when the beam reflects from the surface at the first location. An object to be tidied output signal is issued indicating that an object to be tidied is present based on the determination on the presence of an object.
