In summary, the floor washing machine 100 of the present invention reduces the weight of the machine body 20 by disposing the recovery tank 50 on the base 40, so that when the machine body 20 is inclined or laid at a large angle, the waste liquid in the recovery tank 50 does not enter the suction device; the gas-liquid separation cavity 542 and the recovery storage cavity 541 are arranged in an upper-lower layer, so that waste gas and waste liquid are separated in the gas-liquid separation cavity 542, the waste gas is discharged outwards, and the waste liquid flows into the recovery storage cavity 541 for storage, so that not only is gas-liquid separation realized, but also when the floor washing machine 100 inclines at a large angle or moves horizontally, the waste liquid in the recovery storage cavity 541 cannot flow outwards; by arranging the second partition plate 511 in the recycling bin 50, the waste liquid flowing in from the water inlet 528 is blocked by the second partition plate 511 and smoothly flows into the recycling bin body 52, and the waste gas can flow to the exhaust port 513 through the gap 519 between the second partition plate 511 and the first partition plate 520 so as to be discharged outwards, so that the waste gas and the waste liquid are fully separated; through set up intercommunication collection box body 52 and external air current passageway 543 on connecting the lid 51 to can utilize this air current passageway 543 to discharge the waste gas in the collection box body 52, make waste water and waste gas can get into collection box 50 smoothly, further improve the cleaning efficiency of scrubber 100.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
