The design principle behind this, according to the designers were more or less an ergonomic issues of when the user is required to bend down with the dustpan to collect the debris. “Cuum” is actually designed as a trash bin with a vacuum cleaner embedded as its base. With the vacuum unit incorporated at the trash bin base, it solved that ergonomic issues immediately as the debris are sucked into the unit as it is swept closed to the base of the bin which could then be emptied like your everyday household vacuum cleaner.
