Employing an omega-shaped airflow, this large-capacity, five-liter vacuum cleaner includes a rear exhaust, breaking away from side exhaust arrangements, which restrict low noise design and result in reduced size. The multifunctional area, including the dust bin, accessories, and buttons, was reinterpreted with a single character line, producing a simple interface. Ball bearings were attached to the wheels, and a 360-degree swivel hose overcomes restrictions on movement. The washable HEPA filter removes the possibility of dust getting into the air and allows for long-term maintenance.
