Applicant has created vacuum apparatuses with improved stability and methods for improving the stability of a wet/dry vacuum. In one embodiment, the apparatus includes a motor, a removable drum adapted to store debris collected by the apparatus, and a base that can be adapted to receive the removable drum. The motor can be adapted to be interposed between the removable drum and the base. The methods can include the step of providing a base, the step of providing a removable drum adapted to be coupled to the base, and the step of coupling a vacuum motor to the base such that the vacuum motor is adapted to be disposed beneath the removable drum when the drum is coupled to the base. By relocating the motor of vacuum apparatus beneath the drum, the vacuum's center of gravity can be lowered significantly and, thus, its propensity to tip over is minimized.

The disclosure provides a fan assembly and a vacuum cleaner with the fan assembly. The fan assembly includes a motor, an impeller and a fan housing. The impeller is driven by the motor, which includes an impeller air outlet and an impeller air inlet. The impeller air inlet is located in the axial direction of the impeller, and the impeller air outlet is located in the radial direction of the impeller. An air channel is formed inside the fan housing, and the impeller is at least partially housed in the fan housing. The impeller rotates relative to the fan housing about the rotational axis, the generated airflow enters the air channel during the rotation of the impeller, and the height of the fan housing in the direction of the rotational axis increases along the direction of the air flow.

A dust collector including a body with an intake portion and an exhaust portion includes a filter, a filter support that supports the filter, a motor case protruding from an inner surface of the body, and a vibration motor accommodated in the motor case. The body accommodates the filter support. A portion on the tip side of the motor case is at a position where it is allowed to come into contact with the filter support when the vibration motor is driven.

A cleaner is provided. The cleaner includes a transfer device, and a dust collecting apparatus connectable to the transfer device and configured to filter out rubbish transferred from the transfer device. The dust collecting apparatus includes a housing in which a first dust chamber is formed, and including a guide recessed inwardly from an outer surface, a handle configured to be movable on the outside of the housing and provided to cover at least a portion of the guide, a first rubbish removal member configured to be movable inside the housing based on the movement of the handle, and configured to discharge rubbish collected in the first dust chamber, and a link configured to connect the handle to the first rubbish removal member, and having a movement guided by the guide.
