A cleaning apparatus for floor coverings such as carpets in which a suction creating means such as a fan or fans is supported by a casing and adapted to draw air through an intake orifice. A brush is provided in or within the vicinity of the orifice and is capable of contacting and brushing a floor covering. There is also a chamber adapted to receive cleaning fluid and a large volume of air under pressure, with the cleaning fluid and air forming foam within the chamber. The foam produced in the chamber is delivered through an outlet to the floor covering for cleaning purposes. The arrangement is such that when the apparatus is moved over the floor covering, the brush can be operated to remove unwanted matter from the floor covering, both cleaning fluid and air can be delivered to the chamber and a comparatively dry foam produced, with the foamed cleaning fluid delivered to and deposited on the floor covering, and the brush moved over the covering to brush the covering and simultaneously the suction means remove loosened dirt from the covering.
