Abstract
A multi-purpose cleaning device is provided that can be used with multiple different types of cleaning attachments. The cleaning device includes a handle that is attachable to a socket device that includes several claw members. The claw members have interior portions that are contoured so that the space between the claw members forms a sphere-shaped socket. The cleaning attachments preferably include a ball portion that can be securely mated within the sphere-shaped socket. When the user prefers three degrees of freedom for the attachment, the ball has impeded rotation within the socket. When the user prefers one degree of freedom for the attachment, the ball also includes a rod or post that can releasably lock the ball to the socket.
