I don't need to spend all that money......I have a 1943 model(though it is very difficult to get spares for it now) there is no problem with it getting stuck under items of furniture....it just ignores these and vacuums round them.......it has developed an irritating, grumbling whine recently, but a whack with a rolled up magazine silences it very efficiently(though only for a few minutes)....the good thing about this cleaner is that it washed up too!
Margaret...on a more serious note...I am glad you are pleased with your buy....and there is one thing about it......it won't fail to turn up because there is snow on the ground and no buses were running.
