ABSTRACT:
A sweeping and wringing apparatus comprises a cleaning head, a squeezing head, a main rod, a wringing rod, two connecting rods, two transverse bars, and two squeezers. The two transverse bars are symmetrically fastened to front and rear parts of the squeezing head at a fixed mutual distance. A plurality of squeezing sections is put excentrically over the transverse bars, forming two lines. When the cleaning head is pulled up to be wrung, passing through between the two lines of squeezers, the squeezers turn, with a gap in between gradually becoming narrower as the cleaning head moves upward, resulting in effective wringing of the cleaning head.
