Cleaning device and cleaning method

A cleaning method for use with a cleaning device, the cleaning device including:

• a main body section having:
• a first longitudinal surface extending in a longitudinal direction of the main body section;
• a second longitudinal surface extending in the longitudinal direction opposite to the first longitudinal surface,
• a first longitudinal edge extending in the longitudinal direction between the first longitudinal surface and the second longitudinal surface;
• a second longitudinal edge extending in the longitudinal direction between the first longitudinal surface and the second longitudinal surface opposite to the first longitudinal edge;
• a first transverse edge extending in a transverse direction of the main body section at a first distal end of the main body section;
• and
• a second transverse edge extending in the transverse direction at a second distal end of the main body section opposite to the first transverse edge;
• a cloth sleeve configured to envelop the main body section and define a first primary cleaning surface along the first longitudinal surface, a second primary cleaning surface along the second longitudinal surface, a first secondary cleaning surface along the first longitudinal edge, and a second secondary cleaning surface along the second longitudinal edge;
• a first cord fastener operably connected to the first transverse edge;
• a second cord fastener operably connected to the second transverse edge;
• and
• a pull cord tethered to the first cord fastener and the second cord fastener,
• wherein the main body section is configured to be rotated about its longitudinal axis between:
• a first cleaning position in which the first primary cleaning surface is oriented downward in a vertical direction that is perpendicular to the first longitudinal surface, and the first primary cleaning surface and the first secondary cleaning surface are configured to engage with a cleaning target when moving in a first movement direction, and
• a second cleaning position in which the second primary cleaning surface is oriented downward in the vertical direction, and the second primary cleaning surface and the second secondary cleaning surface are configured to engage with the cleaning target when moving in the first movement direction,
• the cleaning method comprising:
• applying a cleaning solution to at least the first primary cleaning surface of the cleaning device;
• orienting the cleaning device in the first cleaning position;
• pulling the cleaning device across a first cleaning target using the pull cord while in the first cleaning position;
• applying a cleaning solution to at least the second primary cleaning surface of the cleaning device;
• orienting, when the first primary cleaning surface achieves a contamination threshold, the cleaning device from the first cleaning position to the second cleaning position by rotating the cleaning device around its longitudinal axis using the pull cord;
• and
• pulling the cleaning device across a second cleaning target using the pull cord while in the second cleaning position.
