I am sure that you have heard of Dyson vacuum cleaners. They are some of the best vacuum cleaners ever made.
You can buy Dyson Spares & Accessories, as well the actual vacuum cleaners.
You get a 5 year guarantee with each vacuum cleaner. They may seem pricey but they are worth every penny. I have seen them in action and they put my vacuum to shame. I cannot wait for mine to break down so that I can buy a Dyson!
