Totally agree. I purchased several different makes of vacuum cleaners, from very expensive to much cheaper. None of them ever really did thejob I expected and hoped they would do. Then three and a half years ago my kids gave me the air ram and hand held one for christmas. From the start I knew this was exactly what I had been looking for over the decades.
East to use, light to move, powerful suction, easy to clean, etc. etc. When I was in my house it did both upstairs and downstairs with ease and efficiency and hand held one did stairs very well, and my car. In my flat rarely use the hand one, but it i good to have it. The upright goes with ease over my bedroom carpet the rug in my living room and the hard floors for the rest of the flat, with the handle folded down it stores easily.
Hopefully, will not need replacing,but when it does will probably be by another GTech.
