The GTech that I bought, when they first aired years ago, was used upstairs but it finally died and that’s when I put the Shark in its place and bought the GTech platinum.
GTech’s customer service are excellent and gave me plenty of ideas over the phone to try to “repair” the old one but, in the end, they said I’d need to replace the bit that holds the brushes as that’s where the fault was. Instead, I ordered the platinum while I was on the phone to them. It was delivered the following day with free P&P.
