When you know you've bought the wrong one
When i found myself sweeping
the carpet with a dustpan and brush rather than hauling out the newish vacuum cleaner. ( well I had to give it a chance.
It would suck the nails out of the floorboards, but wouldn't pick up a bit of thread, weighed a ton . I could go on....and on.....
Replaced it today. Anyone want a c##p nearly new vacuum cleaner?
