What's not to love about Numatics? Other than the facts they perform no better than any other straight suctions cylinder on carpets, for everything else and hard flooring, they are bang on. Very simple design, they last forever, very good quality materials, solidly built, large, cheap bags with great filtration and inexpensive for what it is and to top it off, it is British built! Right down to the ball bearings and ground up plastic.
If they only done a PN version, somewhat better than the Henry hound. If it had a SEBO PT1 head or whatever the one is sued for the Felix, it would be perfect.
