PURPOSE: To provide a machine for removing gum which is easily usable even by a female operator by providing the machine with a scraper for peeling the deposits on a floor surface, a nozzle near the scraper and a refrigerant ejecting device which ejects a refrigerant to the deposits.

CONSTITUTION: The refrigerant ejecting device 11 consists of a a nozzle 12 for ejecting a refrigerant, a refrigerant tank 13 housing the refrigerant and a solenoid valve 14 for controlling the stop of the refrigerant from this refrigerant tank 13 to the nozzle 12. The scraper 6 is installed just before the gum 31 and the solenoid valve 14 is opened by turning a refrigerant ejecting switch 18 on to harden the gum 31 by the refrigerant. A motor 3 is driven by turning a scraper switch 17 on and the gum is peeled by forward and backward reciprocative driving along the floor surface 30 of the scraper 6. The peeled gum 31 is scraped by a rotary brush 9 and is housed into a dust bin container 10 by floating the scraper 6 and moving the scraper forward.
