Estimating the term…
The invention relates to an apparatus for floor cleaning, with several wheels 4, 5, 6 being attached to a frame R in such a way that a curve movement about a momentary center MP, MP1, MP2 can be performed and all momentary centers MP, MP1, MP2 form a momentary center axis MA extending substantially transversally to the frame R, and with a cleaning device 24a, 24b being received in the frame R, which cleaning device forms a cleaning surface area RF which is delimited by a circumferential edge. In order to reduce uncleaned residual surfaces when moving along contours it is provided in accordance with the invention that the momentary center axis MA forms at least one point of intersection S1, S2 in a section of the circumferential edge disposed in the zone of the longitudinal side of the frame R.
An apparatus for floor cleaning, said apparatus having a plurality of wheels (4, 5, 6) attached to a frame (R) such that a curve movement can be selectively performed about any one of a plurality of momentary centers (MP, MP1, MP2), wherein each of the wheels has an axis of rotation and each of the plurality of momentary centers (MP, MP1, MP2) is located at an intersection of a momentary center axis (MA), which extends substantially transverse to the frame (R), and the axes of rotation of the plurality of wheels, said apparatus also having a cleaning device (3, 17a, 17b, 24, 25) that is received in the frame (R), said cleaning device forming a cleaning area that is delimited by a circumferential edge, wherein the momentary center axis (MA) forms at least one point of intersection (S1, S2) with a section of the circumferential edge that is disposed along a longitudinal side of the frame (R).
