Domestic Surface Treatment Appliance Provided with Tracking Means and Tracking Module for Use with Such Appliance

Abstract

The invention relates to a domestic surface treatment appliance ( 1 ), such as a vacuum cleaner, iron or lawn mower, provided with a treatment head ( 2 ) for treating a surface by wiping along or passing over said surface. The appliance ( 1 ) furthermore comprises tracking means ( 12 ) for recording wiping movements of the treatment head ( 2 ), and a user interface ( 15 ) for presenting the recorded wiping movements as strokes (S) on a display ( 16 ), enabling a user to readily spot missed surface parts. The appliance ( 1 ) may further comprise quality detection means ( 14 ), for measuring a parameter representative of the achieved quality. This quality parameter can be presented to a user by the color of the strokes (S). The invention furthermore relates to a module ( 10 ), comprising tracking means ( 12 ), a user interface ( 15 ) and possible quality detection means ( 14 ), for use with a domestic surface treatment appliance ( 1 ).
