OEM Miele Bags
I have three Miele vacuums - S4, S5, and a brand new S8. The 4 is used in my small studio apartment, the 5 in my condo, and the new 8 in the big house. In my opinion, and I do know vacuums, is the Miele canister vacuums are the best vacuums in the market place. Superior suction, air flow, and filtration. Plus the added benefit of being able to customize each vacuum to YOUR particular needs, not what some uninformed engineer thinks you need.
Also, as an owner of a few top of the line Electrolux vacuums, I would never use any type of bag that was not OEM. Using off brands just increases the risk of motor damage, reduced air flow, and inferior filtration. If it is recommended by the manufacturer, I use them and nothing else. If you are willing to spend the money for a high line vacuum, why cheap out on the bags. If you do not want to spent money on bags, buy one of those useless bag less vacuums.
Someone on this site has a thing for bashing. Miele vacuums are absolutely not fragile. Anything will break if abused. I treat all my vacuums, in fact all of my things, with respect and care. Recently I gifted my Electrolux Super J to my housekeeper. When I informed of the vacuums age, she was shocked. It looked brand new. Care and respect is what it is all about.
A great day to all,
Richard
