which worked adequately
I completely disagree. The total systems, when compared to Electrolux and Panasonic cleaners of the time, were not better as uprights but very poor on the hose. Other manufacturers where offering equal performance between hose suction and carpet pick up WITH the added bonus of the tools being built onto the machine.
The Turbopower 1 was never meant to have tools and by adding them, Hoover made the machine excessively wide and bulky to use. With the on board hose, the Turbopower 1 didn't reach the edge of the skirting, for example.
