Low suction power had the Argos cleaner struggling to vacuum up the flour and sugar and it was quick to clog when tackling the corn flakes. This slow performance was compounded by the shorter running time. We had another problem, too: the internal flap that stops the dust coming back out of the nozzle once the cleaner is turned off came loose every time. We had to hold the cleaner upright and fish through the dust to retrieve it. To empty the unit just press a button to release the front and pull out the filter.
