Biggest waste of money, would not entertain it, we have had two the mark one and mark two k9, you spend more time messing about emptying and cleaning filters than you do actually hoovering up, and the charging system is hopeless, if this light flashes you do this, if that light flashes you do this, and the customer service center havn't a clue, each person tells you something different everytime you speak to them. The only reason we have had two is because the first one broke and we got the second half price, not an exchange, most other companies would have just swapped it, but not g-tech,half price. Would not give them one star.
