...perhaps that model does not leak air. Go to an Aerus retailer or if you know of someone who has a current Legacy model or the Guardian Upright like I do, turn on and feel the underneath of the Upright near the duct hose at the base before the power head and you will feel air blowing out from the connector cord. On the Legacy you will feel air escape from the cord winder hole and/or the handle sometimes. I do not know if this is every machine, as it could just be hit or miss. It happens to mine, I think the air passes through the bag and then gets forced through the seams by the duct hose before getting pushed out through the side HEPA filter.
Everyone on this post seems to ignore this, touting its such a great brand, its the best... nothing is the best! Yes the Platinum is much more solid, but the other models have small issues if you really look them over carefully. My Guardian does not even have LED headlight, something I wish it did. I like my machine, but the S7 is better IMO
