Dyson type vacuum blocks in 10mins!!!!?

Its a cylinder bagless vacuum cleaner - (cheap off the internet) worked a treat for 10mins then the filer became blocked and all suction was lost. Seems like a fundamentaly flawed designed to me. I'm wondering if the design doesn't spin the air properly so the particles aren't 'throw out' and consequently just stick to the filter.

Anyone else found this? Maybe expensive vacuums are pricey for a reason? Its called a Supportplus from a German company called H.ab.
