I've posted this before but Ho Hum.'enrys are made by Numatic who make big fuck off commercial vacuums with 2 or 3 motors 'enrys are designed exactly the same,simple and solid (and crap on stairs).One of the most common faults on Vacuums is the cable failing on the retraction drum, doesn't happen on 'enrys because the drum is big enough in diameter not to cause cable failure.Mieles etc are fine but they won't take abuse like a Numatic.Personally in my view Nilfisk make the best cleaners.
/end rant.
