An apparatus is described for disinfecting and sanitizing up to three brushes with steam, where the brushes are placed in a horizontal position in the apparatus, such that the handles of the brushes protrude from the apparatus and are not exposed to the steam generated for disinfecting and sanitizing the brushes. When the absolute value of the acceleration detected by the acceleration sensor is above the prescribed threshold, the navigation device calculates the present position based on the previously detected values of the position and running speed stored in memory. The outboard wing roller or slider bar is attached to the support structure and is able to translate relative to the support structure only along a linear path.
