Abstract
An automatically traveling floor dust collecting appliance has at least one running wheel having an axis of rotation, a hub, and a tire forming a tire contact area merging radially inwardly into two oppositely situated side faces. The tire, which includes elastic material, has profile blocks, each forming a part of the tire contact area and provided one after the other in the peripheral direction. A running wheel is also provided, in particular for a floor dust collecting appliance. The part of the tire contact area formed by a profile block has a profile which in its cross-section slopes downwardly toward the center. This profile block at the same time forms a part of an associated side face. The profile block, at this transition, radially and in the direction of the axis of rotation, forms a farthest protruding portion of the tire contact area of the tire.
