摘要： A cleaning device and a sweeper, the cleaning device includes a driving module (12), which includes a lifting driver (121); a lifting module (14), which includes a first shaft sleeve (141) and a second shaft sleeve (142), the first shaft sleeve (141) is connected with a power output shaft (122) of the lifting driver (121), a screw mechanism is formed between the first shaft sleeve (141) and the second shaft sleeve (142); and a cleaning module (13), which includes a cleaning member (131) connected with the second shaft sleeve (142); the screw mechanism is at least is subjected to a first driving force of the power output shaft (122) of the lifting driver (121) to drive the cleaning member (131) to perform a descending motion relative to the lifting driver (121), and is subjected to a second driving force to drive the cleaning member (131) to perform an ascending motion relative to the lifting driver (121). The cleaning device and the sweeper may prevent the cleaning member (131) from polluting a carpet, effectively protect the carpet, meanwhile, may prevent the cleaning member (131) from causing secondary pollution to the cleaned floor after the sweeper finishes cleaning, and improves a cleaning effect of the sweeper.
