I have an upright Dyson, my second in twenty plus years. Can't fault the cleaning or reliability BUT it weighs a ton and the attachment tube is so strong it's always fighting to get back to the main unit. Having tried my daughters cordless Dyson, it was excellent but you have to have it docked to the charging unit on the wall and I didn't want it on show. I also wanted a vacuum that would go under my low bed without having to move it. After talking to Gtech to check all that I opted for theirs and it's brilliant, just wish I'd bought the hand held for the stairs at the same time as I won't now get it on offer now. It's easy to empty, has a light for dark corners, the suction seems as strong as the big Dyson, it goes down flat for under low furniture and the handle will shorten too. Charging is easy, just bring it out of the cupboard and plug in to any socket, no need for a permanent dock fixed to the wall. I would say though that you really need the upright and the hand held for stairs and small nooks and crannies. I'm going back o have to spend more to get that now.
By the way, I have a Henry too but that lives in garage for outside cleaning. Too heavy for indoors.
