Can you not get a vacuum that can be cordless AND corded?
I've been looking into cordless cleaners as our main vacuum as old Dyson about to die and I hate it anyway. Battery life is an issue though as I need to clean a 2 up 2 down with hard floors downstairs and carpets upstairs, stairs with wood and carpet stair runner, dog hair, use it to pick up cobwebs and spiders all round the house, dust fireplaces, dust skirting, dust some blinds and shelves and mantelpieces with the brush bit etc. Then sometimes also the car(s). I'm not convinced I could do it in 20-30 minutes and I am very busy and work full time so generally can't split it over the week, just a Saturday morning.
Now I don't want a corded vacuum but I'm wondering why I haven't seen any cordless that you can plug in when you need to (like charging your phone but you can still use it). Do you really have to charge them for hours before you can use them again? We're nearly in 2016, does this not exist or have I missed it?
If not, then the ones I'm looking at just now with decent battery run time and suction include the Bosch Athlet which looks good as an upright but the tools seem like a pain in the back side to use and obviously I'd need them...or the gtech but I'd need to buy the multi as well which gets very expensive!
