At the supermarket around the corner they wanted to have smooth 10Euro for a SWIRL bag of the same variety. First, a buy in the store, to test whether the quality is comparable with the supplied Siemens anthers. Can see no disadvantages, except that the level indicator on the unit signaled too soon the bag was full (this he showed well at Siemens bags on).
So buy on shipping 5Packungen for ca.30Euro incl. Shipping.
The bags can be good and change is very well located in the holder. You just like the original bag a "slider" to close the bag to prevent dust escaping when emptying.
In each pack a filter is free in the package. This I have not yet changed.
So you get here 20Filter for ca.32Euro what per bag thus means ca.1,60Euro (in the supermarket around the corner: 2,25Euro). Savings compared to supermarket: 18Euro = 3Packungen.
Can the vacuum cleaner bag Swirl recommend at the price!
