Abstract
A surface treatment device, in particular a cleaning robot, has at least one optical device element and an evaluation unit. The optical device element is configured such that light emitted by the optical device element is at least partially reflected to an optical device element by means of the external element. During an interaction of the optical device element and the external element for the purpose of detecting a presence of smoke between the optical device element and the external element, the evaluation unit evaluates a measurement signal received by the optical device element with respect to a temporal change in signal amplitude, and triggers an alarm signal when a defined threshold value has been passed.
