Agree with the judgment of the previous speaker ...

The bags are made to last, the existing volume of the bag multiple use so quite well (Other bags for other vacuum cleaners are just as great, but unfortunately the bag compartment is so small that can never be filled right ...), but are, for a disposable, expensive (just like other well ...). I also believe that the suction capacity decreases with increasing not as pronounced as in many other instances.

So here, too, an asterisk deduction only wg. Price.
