A mop handle connector which is removably attached to the end of a mop handle and is typically fitted with a clamp to facilitate removable attachment of a dust mop frame to the mop handle. In a preferred embodiment the mop handle connector is characterized by a connector plate, one end of which is threaded into the end of the mop handle and a conventional clamping mechanism is pivotally attached to the opposite end of the connector plate. A lock ring may be slidably disposed on the connector plate and can be selectively brought into engagement with the clamping mechanism to maintain the attached dust mop frame in a rigid position with respect to the mop handle, or disengaged from the clamping mechanism to allow the attached dust mop frame to pivot with respect to the mop handle.

An injection-molded receiver for securing a mop handle, broom handle or alternative cleaning or utility handle to a mop, broom or other cleaning or utility implement or tool having a threaded mounting stud. The injection-molded receiver includes a receiver cap having a cap opening for receiving and mounting one end of the handle and a cap base integrally formed in the receiver cap and fitted with an internally-threaded insert having flange cleats which is injection-molded into the cap base for threadably receiving the threaded mounting stud attached to the cleaning or utility implement, for example, a screw-type mop head. Injection-molding of the insert in the cap base of the receiver facilitates stability, longevity and ease of coupling a screw-type mop or similar utility implement or tool to a handle.

The present invention entails a method and apparatus for cleaning and maintaining large areas of low to medium pile carpet, such as is found in hotels, airports, etc. The invention employs a mobile carpet cleaning machine which is propelled over the carpet to be cleaned. The principal features of the carpet cleaning machine are an elongated cylindrical brush, a vacuum system with a floating vacuum head, and a blower. In operation the cylindrical brush is set into a rotating motion and engages the underlying carpet. A cleaning solution is sprayed onto the rotating brush which in turn transfers the solution onto the underlying carpet. The vacuum head then passes over the carpet directly behind the rotating brush. The blower pulls air through the vacuum head and the vacuum head effectively picks up a combined mixture of air and solution. This mixture of air and solution is pulled upwardly from the vacuum head into the top of a recovery tank. Once the mixture enters the tank, the solution falls out and the air is induced up into a tube where the air is then directed to the blower. Once in the blower, the air is heated and directed back down onto the carpet through an outlet located directly behind the vacuum head for the purpose of drying the carpet. Thus the entire cleaning operation requires only one pass over the carpet.

Method and apparatus for cleaning and maintaining carpet

The present invention relates to a cleaning solution dispenser attachment for a rotary floor cleaning machine that is adapted to dispense cleaning solution on demand as the floor cleaning machine is moved over an area. Cleaning solution dispenser attachment is designed to be detachably secured to various size motor housings of a rotary floor cleaning machine, and can be rotatively adjusted thereon such that a dispenser arm or jet tube that extends outwardly therefrom can be positioned at various locations around the motor housing.
