I have recently bought a Bosch Athlet cordless vac. It is lightweight, easy to use and far far better than I hoped after asking a couple of people. Before buying I read comments on the Internet and found many women saying the same as me. It goes under our bed with ease. I can whip round with it very quickly - kitchen, dining room and sitting room - I have wooden or tiled floors with large rugs. It has three power levels and I find the middle one is sufficient most of the time -25 volt lithium battery. It has a charger and lead which I find more convenient than a wall charging point would be and I am only charging it when it runs out. It came with a spare washable filter and although the dust 'bin' is small it is very easy to lift out and empty. I have accessories with mine which you could use for the stairs etc but I have highish ceilings so it would not reach them - my old brush will still be better for that. I paid £155 on offer in Costco for mine but it would likely be more in other outlets.
