Abstract: An airflow sensor system for monitoring air inlet airflow and air outlet airflow of a vacuum cleaner is provided according to an embodiment of the invention. The airflow sensor system includes a vacuum cleaner air duct, a bypass tube connected to the air duct, and an airflow sensor positioned at least partially in the bypass tube. The airflow sensor is configured to generate a normal voltage differential range when the bypass tube airflow is within a predetermined normal airflow range, configured to generate an input blockage voltage differential range when the bypass tube airflow is greater than the predetermined normal airflow range, and further configured to generate an output blockage voltage differential range when the bypass tube airflow is less than the predetermined normal airflow range.

Abstract: Fragrance delivery apparatus and methods for use in combination with a floor care device are shown and described. In one embodiment, the fragrance delivery apparatus incorporates a mass that can be impregnated with a heat sensitive, fragrant substance. The fragrant substance is substantially stable at ambient temperature, but is freely released from the mass at an elevated temperature. The mass is coupled to a housing on a floor care device at a location that becomes warm during operation. As a result, when the floor care device is operated, the fragrance delivery apparatus becomes warm, and the fragrant substance is released into the nearby environment. When the floor care device is stored, however, the fragrant substance is not released from the mass in significant amounts.
