Disclosed a dual-function electric stair-climbing vehicle. A bicycle-like saddle is mounted at an upper part of a frame of the vehicle; and a worm gear reducer is mounted at a middle part of the vehicle for driving two rotating legs to climb up or downstairs. The vehicle is mainly used for fire rescue in high-rise buildings, equipment maintenance of high-rise buildings when no elevator is available, and fast transportation of equipment, materials and firefighters or maintenance men upstairs. When the width of a corridor is greater than 1.1 m, the vehicle can be rode upstairs directly with people and goods; when the width is less than 1.1 m and greater than 0.9 m, people need to get off and make a turn; and when the width is less than 0.9 m, the vehicle is not available. The dimension of the frame is about 1200×550×380 mm.

A rollable hamper assembly for transport of laundry and laundering supplies includes a housing having walls coupled thereto and positioned therein to define a chamber and a plurality of compartments. The chamber and compartments are used to stow articles and are accessible from an upper and rear face of the housing, respectively, which are open. An upper lid selectively closes the upper face of the housing. A pair of first rods is engaged singly to opposed sides of the housing, proximate to the rear face. The first rod comprises a plurality of nested sections and is selectively extensible. A second rod is coupled to and extends between the first rods distal from the housing. The second rod can be utilized by a user to motivate the housing upon rolling wheels, which are engaged to a bottom of the housing. The second rod can be used for hanging items.
