Okay, that is "specially designed" to store more dust but it is not cheap .. it's even more than before and only 4 bags per pack ... and to recover a swallowed object inadvertently not convenient ... And do not forget to change the time to filter cassette following the same trend. This becomes a luxury of spending the aspi? There are plans to move to the "bagless" from another brand so that this vacuum cleaner is very effective but only if the engines filters do not cost an arm and a head.
