I already have a bought brand new full price version which I love, even though, sadly, it came without instructions. I have difficulty carrying vacuum cleaners around my house, especially up stairs. I wanted to keep this one on the first floor of my largish house. It appears to be really powerful. It arrived fully charged. Only after using an item for some time can you really be sure if you have a good item or not. Most machines start off being impressive. They are only value for money if they stay impressive. Early appraisals/reviews are usually positive, but are no true indication of performance after some time . Ask me again in 18 months. I am, however, optimistic about this vacuum. Of course it may fail quickly. It has a one year guarantee which is very reassuring.
