A wall-mountable mounting bracket and fluid-dispensing attachment for a vacuum cleaner. The attachment can be used to dispense cleaning fluid to an area to be cleaned. The fluid is sucked up along with dirt by the vacuum. A remotely-activatable valve allows user's to selectively shut off the flow of fluid. Retractable wheels can be moved between a usage position and a storage position. In the storage position, the axis of the wheels is above the lowermost side of the attachment and any overhang of the lowermost edge of the wheels is less than the thickness of a corresponding part of the mounting bracket.
