The upholstery tool that comes with the Elite also came with a Dirt Devil I bought many years ago - and it isn't all that kind to fabrics especially curtains and cushions that may well have unravelling threads. The biggest problem I found with the tool are the back teeth gorged out of the plastic at the back. It may well be designed to catch threads, but it also catches threads in a damaging way.
Lint pickers or stiff bristles are far better - another tool that is worthy is the upholstery tool fittef to the Hoover TP3 model - has a row of red bristles and lint pickers - the best of both worlds in my opinion - and without unnecessarily damaging things.
I do miss Hoover cleaning tools of old - the same dusting brush equipped with the uprights like TP2/3 etc also found their way with Hoover's Telios cylinder vacuums and later models.
