Question about Miele canister vacuums
I posted a similar message on the Appliance forum. Not sure where the best place is to get help. Does anybody know how much difference it makes to get the "Sealed System" canister construction on a Miele canister vacuum as opposed to the "CleanAir" canister construction? We want a model with a power brush for carpets. The Delphi has this for $499, but it has the CleanAir construction. To get the Sealed System you have to move up to the Libra model at $849. Does anybody know if having one system rather than the other make that much difference in capturing and containing dust and those pesky dust mites? Thanks in advance for your help!
