Abstract
Systems and methods for monitoring the cleaning conditions of a facility include the use of a cleaning apparatus with a tracking device. The tracking device is adapted to detect an operating parameter of the cleaning apparatus. In embodiments, the operating parameter includes at least one of the location of the cleaning apparatus within a facility over time, the movement of the cleaning apparatus, and the dynamic coefficient of friction encountered by a cleaning head of the cleaning apparatus as it traverses a surface being cleaned in the facility.
Claims20
A cleaning apparatus comprising:
- a scrubbing member;
- and
- a strain sensor configured to interface with the scrubbing member,
- wherein the strain sensor is further configured to measure a resistance encountered by the scrubbing member as the scrubbing member moves along a surface being cleaned,
- wherein the strain sensor is further configured to measure a level of tension for moving the scrubbing member laterally along a surface being cleaned,
- wherein the level of tension corresponds to a level of effort,
- wherein the strain sensor is configured to generate a strain signal indicative of the resistance and the level of effort, and
- wherein a dynamic coefficient of friction is determined from the strain signal.
A method comprising:
- measuring, with a strain sensor, a resistance encountered by a scrubbing member as the scrubbing member moves along a surface being cleaned;
- measuring, with a strain sensor a level of tension for moving the scrubbing member laterally along a surface being cleaned, wherein the level of tension corresponds to a level of effort;
- generating, by the strain sensor, a strain signal indicative of the resistance and the level of effort;
- and
- determining a dynamic coefficient of friction from the strain signal.
