I find the best are:
Hoover's "veriflex". tons of it are still working well.
Hoover's "ultraflex" works si ell, too.
Hoover's "Tufflex" is about the best.
Hoover's 'pool filter' is "lackluster". It's found on lots of the plastic stuff.
The hose on the Connies would cut near the wand, from lots of use. Luckily, it can be cut off and reattached. Never had an issue with any of my cleaning tools. The cleaners always follow me around the house.
