Great thing about henrys every spare part available made in england i think the plastic tub on numatic is made of a stronger resin motor the same motor replacement £30
Thats a very good point indeed.
Spares are very important. And there is a wide variety of stockests available. Where as dysons are not designed for commercial use.
Cable lengths is good on henrys and is important some Numatics have longer that 12.5 metres.
As for power I would say that providing that they are looked after and a checked that the bag is not full the power is more than adaquate. Some cleaners have it just on the LO power setting as the Hi power setting makes it awkward.
