dont even have a vac on the van
so no never . I have done it in the early days but to be honest - the end result was no different .
I done a few courses and yes thats what they say , but also at the same time i was was getting training of a guy with 30 years under his belt , when i come back all excited , told them about the hoover part , the guy and his son just looked at each other and laughed
big stuff gets swept up with pile brush - the stuff missed as I go along gets the hose taken off the wand and sucked up .
if the water dont manage to go through the motors im sure a bit of fluff or the odd sweet will be kept by the filters.
berfore i get slated lol - ive had the ninja 7 years and only on new vac motors last year .
anyway if you using a BAG hoover like a sedo or orek etc you loosing suction as you go along -- havnt you seen the dyson adverts lol
I bet those that do also have a van full of chemicals for this and that also ??
