Abstract
A vacuum cleaner includes a device for dispensing atomized liquid, the device having a reservoir for holding liquid and an ultrasonic transducer arranged to atomize the liquid in the reservoir. An airflow is created through the reservoir via the exhaust gasflow from the vacuum cleaner, the airflow carrying the atomized liquid via an elongate tube to dispensing outlet provided on a cleaning head of the vacuum cleaner. The ultrasonic transducer is simple and inexpensive, yet is able to reliably atomize the liquid for dispensing.
