No vacuum bag is sold with its liter capacity: a boon for manufacturers that can gradually reduce the size of their bags to reduce their lifespan and so you do buy more. It makes you believe that it is cheaper to buy them by 12 (this is taking a risk if the device fails before the end of the stock), but if you are removed 1/3 capacity, this means buy 8 bags only!
In addition, the attachment of the bag has been rotated 90 ° with respect to the proportions of the front of the bag. Suddenly, the bag is too narrow and can not occupy the entire width available in the device and is a little too deep, so it will not fill completely. I call it "a clever scam".
I was happy with my Electrolux vacuum cleaner so far, but this type of swindle has reduced dramatically my enthusiasm. In 3 years, I consume only 9 sacks for 75 m² with 2 sucking cats. I think my bag consumption will change strangely.
