Stick vacuum (Larkhall, bath)

Had this for about 3 years and it's been great, unfortunately recently it's battery life has started to drop. It used to run for about 20 mins now lasting only about 10 which just isn't enough to do my house and its battery is not replaceable. I do believe it would be ideal for someone in a smaller property without dogs to deal with. I was dealing with the battery issue but now the rota blade has stopped turning as well I think this could be fixed easily but I've decided to replace the hoover.
