    Abstract: A pool tile cleaning device (1) having a hollow handle (2) and a cleaning head (3) on a distal end (20). The handle (2) acts as a cleaning product reservoir (25) and is attached to the cleaning head (3). The cleaning head (3) has a scrubbing means (5) located thereupon in order to effectively remove dirt and grime from pool tiles. The device (1) is gravity fed and provides a continuous distribution of cleaning product through the handle (2) to the cleaning head (3). A metering valve (17) is located at the distal end of the handle (20), behind the cleaning head (3), so as to control the amount of cleaning product that is distributed onto the cleaning head (3). A purge valve (10) is used in conjunction with the device (1) to permit air to enter the reservoir (25) as the cleaning product exits the reservoir (25).
