Have both GTech upright and hand held. Had them for two years now. No idea where people have found fault with these, Mine were used originally in my house, (hard floor downstairs, carpet on stairs and upstairs), and now in my (at present ) fully carpeted flat. I have absolutely no complaint with their use in any way. I am elderly, with arthritus, and between the two machines, I have everything I have ever looked for in vacuum cleaners.
Easy to use, powerful,, easy to empty and easy to charge. Fold down handle on upright makes them easy to store.
