Brian, Miele wasn't the first to make a battery-operated
That credit belongs to EIO, another German firm that competes with Miele. They first had a battery-operated p/n when they introduced the EIO Varia canisters to North America a few years ago. If memory serves correct, both the EIO & Miele p/n's are made for them by Wessel-Werk.
I was sure that Chris Parker posted some pictures of the Miele AccuNova head recently, and seemed very impressed with it - but I can't find the thread anywhere on this forum, or in the archives! Perhaps I dreamt it? lol
remember Greenville Vacuum and Sewing had a rechargeable powernozzle for Meile vacuums-Last I remember the battery in it died-no customers wanted to buy it-they would buy the electric powernozzle instead-cheaper-and better performance.So the poor rechargeable powernozzle ended up in the trash.
