Replacement for a much heavier mains powered Shark, the benefits of the cordless vacuum cleaner were experienced immediately. Not only did it feel so much lighter and easier to handle, but the advantage of the folding main tube meant that the facility for storage was greatly improved. The flexibility of cordless power was a great gain in both manoeuvrability and safety around the house. Finally, the cleaner's powerful suction adds an improving touch to what is a very welcome replacement in our cleaning arsenal!
