  • Patent number: 11819183
    Abstract: 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.
