Abstract
Aspects of the present invention relate to a recovery tank support structure for a surface cleaning device such as an extractor. The support structure partially encircles and supports the recovery tank removably mounted to a base in order to prevent any unwanted movement of the tank or its contents during operation of the extractor. The support structure creates a void for housing the recovery tank, wherein a locking mechanism may be employed to engage the recovery tank and secure it in position. An upper portion having a handle for propelling the extractor is pivotable about the base independent of the support structure thereby allowing a user access to a wide range of pivoting motion and maneuverability during extractor operation.
