This visibly simple trash receptacle has one hidden talent – it sucks in dust. Equipped with the vacuum in its base, the Cuum dustbin by Jun-se Kim, Yonggu Do & Eunha Seo performs two functions in one. It collects trash and inhales all the small dust particles swept in its direction. So no more fiddling with the dustpan. The device is powered by a plug-in, wall-socket-compatible cord and can be turned on by simply rotating the upper part. And just like a standard vacuum cleaner it requires disposable bags that can be easily changed when taking out the trash. The Cuum is a 2011 IDEA Awards Entry.
