I have the G-tech K9, together with the K9 hand held cleaner, bought as a package when it was on offer, direct from the Gtech website. I am very pleased with it, powerful, easy to use and empty, and gets all my long hairs up off the carpet with its brush head. My daughter was a fan of the Shark cleaner she had, but it broke down just after the warantee was up, so she too has now bought a cleaner the same as mine, and uses it daily to deal with her dog hairs from her Labrador and Spaniel. I also have a Hetty, but that’s mainly for use cleaning out the cars and our caravan, where the long hoses can be very useful for reaching into very narrow Awkward gaps.
