A wiping instrument of this type can be easily handled with a good wiping effect because the wiping strip is dragged and not pushed.

Abstract: A vacuum cleaner introduces dust, as well as air, from a nozzle connected with the distal end of a hose into a dust collecting section in the cleaner body through an intake section, while detecting, by means of a detector, the volume of dust being introduced, and controls the output of an electric blower in accordance with the detected volume. One end of the intake section is connected with the proximal end of the hose, while the other end projects into the dust collecting section. Light-emitting and light-receiving elements are provided in the intake section to constitute the detector so as to enable positive detection of dust, easy checking of the contamination of the detector, and easy wiping of the detector.

Abstract: A vacuum cleaner and method for determining the kind of floor surface being cleaned by a vacuum cleaner wherein dust amount per unit interval is detected and dust detection change patterns are analyzed for determining floor type. This analysis is based on the following assumptions: smooth and carpet surfaces can be distinguished by dust detection patterns for an interval of several seconds. On the smooth surface, almost all of the dust at one place is picked up during an early stage of the interval. On the other hand, on a carpet floor, dust is picked up continuously. On a new carpet, many piles detach during vacuuming. Thus, if dust detection is continuous over several seconds it may be assumed that, the carpet is a new carpet.

Abstract: An electric cleaner is provided with a moving mechanism for avoiding or escaping an obstacle so as to turn and move a cleaner body when the cleaning body collides with the obstacle.

Abstract: A double wheel caster for being rotatably mounted on a leg of a transport carrier includes a support rod having a center portion and opposite first and second end portions. The center portion of the support rod is rotatably positioned within an opening located in a wheel caster trailing housing.

Each caster wheel has an aperture generally centrally located therethrough and a plurality of fingers extending radially inward and into engagement with the support rod such that the caster wheels are frictionally mounted on the support rod. Upon movement of the transport carrier in a direction which forces one caster wheel to rotate faster than the other, the frictional mounting inhibits the one caster from freely rotating with respect to the other to thereby prevent shimmying.
