The filter dirty quickly already after one month and the replacement filters kept as long. The filter determined by the saaugkrafdt, in which case the counter deer advertising is quickly lose suction there.
The plastic handle is broken me the first fall down and a wheel blocked very often after a few days.
I had to get a new (next to the infirmities and the loss of suction) after 3 months despite me ständigemn annoying clean out of principle. Another bag sucker!
