摘要： Rotary devices and methods of use thereof are disclosed. The rotary devices may be configured as cleaning apparatuses. A cleaning apparatus may include an elongated tube member with an attachment end portion, a holding end portion, an internal cavity, and a helical slot. The cleaning apparatus may also include a handle with a following pin, the tube member extending through the handle with the following pin extending through helical slot. The cleaning apparatus may further include a guide element, a stop member, a first resilient biasing element of a first stiffness and a second resilient biasing element of a second stiffness positioned within the internal cavity. Longitudinal translation of the handle along the tube member from the holding end portion to the attachment end portion rotates the tube member about the longitudinal axis and resiliently deforms the first and second resiliently deforms the biasing elements.

摘要： A rotary scrubber apparatus, the apparatus includes a tube member having a helical slot, an attachment end portion, a holding end portion, and an internal cavity extending therethrough. A biasing element is contained within the internal cavity of the tube member. A following pin extends through the helical slot. The following pin has an external portion that engages a handle, and an internal portion that engages the biasing element. A scrubbing element is coupled with the attachment end of the tube member and rotationally fixed therewith. When the handle is pressed towards the attachment end and the handle is prevented from rotating about the tube member, the tube member rotates to rotate the scrubber element. The apparatus thereby provides rotational movement of the scrubber to be generated from only linear movement of the handle provided by a user.
