A rotatable counterweight assembly is mounted on a hose and contains a body and a rotary loop. The body includes a first segment, a second segment, an outer fence formed between the first segment and the second segment, and an open channel longitudinally extending along an X axis and between the first segment and the second segment to define a first opening; a horizontal width of the channel along a Z axis allows the hose placing in the channel, and a radial depth of the channel along a Y axis allows the hose accommodating in the channel. The body also includes an installing groove defined around the outer fence and having two ends communicating with the first opening. The rotary loop is rotatably fitted in the installing groove and is rotated toward an opening position and a retaining position, and the rotary loop includes a second opening defined therein.
