The invention discloses a dust removing sofa, and relates to the technical field of sofas. The dust removing sofa includes a frame-shaped base frame, the base frame is internally and fixedly connectedwith two symmetrically arranged sliding rails, a moving part is slidably connected between the two sliding rails, the bottom of the moving part is fixedly connected with a cleaning part, the moving part is connected with a first lead screw in a threaded mode, the first lead screw is connected with a transmission mechanism controlling forward and reverse rotation of the first lead screw, and the base frame is further internally connected with a driving mechanism for providing power for the transmission mechanism. According to the dust removing sofa, the driving mechanism provides the power forthe transmission mechanism, the transmission mechanism controls forward or reverse rotation of the first lead screw, thus the moving part is controlled to move back and forth on the sliding rails, dust and garbage at the bottom of the base frame are cleaned up by the cleaning part in the moving process, operation in the cleaning process is convenient, automatic cleaning can be achieved, and the cleaning time is saved.
