I have the Menalux 2000 uses a Siemens Synchpower. Unfortunately, these bags have never been put right at the inner opening, which again and again half of the dust and dirt next to the prey, and the vacuum cleaner were nicely spaced and the Moto filter clogged arg.
Instead, the complainant then 5 bags bought at I won and this are now right on.
At least for a Siemens Synchpower I advise of these bags.
