I've got the Gardiner Backpack, very happy with it. I don't use it all that much, usually for houses with very awkward access or ones that have dog crap everywhere. But when I need it, it's great. Holds its charge well and has variable speed control. You can choose to keep the back straps on or take them off. I prefer them out of the way. I just carry it by the handle which, as you probably know, is on the lid. I don't find a problem with that myself. Good value for money.
