ATTACHMENT FOR A VACUUM CLEANER

Abstract: an attachment for use with a vacuum cleaner includes a head housing defining a brush roll cavity, a motor cavity, and a battery cavity, the battery cavity defining a central axis, a brush roll being rotatable relative to the head housing about a rotational axis, and an electric motor disposed within the motor cavity and configured to drive the brush roll, an output shaft of the electric motor rotatable about a rotational axis. the rotational axis of the brush roll is substantially parallel to the rotational axis of the output shaft of the electric motor and the central axis of the battery cavity. the rotational axis of the output shaft of the motor is offset rearward of the rotational axis of the brush roll by a first distance. the central axis of the battery cavity is offset rearward of the rotational axis of the output shaft by a second distance.
