Personally I would be very loathe to touch anything that did not use a dustbag. Dyson in particular waft on about all the filtration they provide to the air that is produced by the motor, and which is subsequently returned to the room you are cleaning in, which is great if you are allergic to dust etc, or suffer respiratory problems. Then what do you do when the dust canister is full, you go to the dustbin or whatever and tip it out, normally getting covered in a shower of dust, thereby cancelling the benefits of all the aforementiond filtration. I used to repair domestic appliances for a living, and although this was several years ago the best manufacturer at that time was, in my view, Panasonic. Easy to use, not expensive and don't weigh a ton. Whatever get something with as few gimmicks as possible, how many times do you use all of the 54 programmes on the washing machine. Sebo, Henry all good machines although Henry had a different motor fitted a few years back, which although it claimed to be more powerfull did not pick up like my old beast, and again these machines are designed for commercial use. good luck.
