The WV 470-2 provides a larger alternative to the 370-380 series, with twice the capacity but to the same high performance standard be it wet or dry.
What is very important is for professional use we do not mix both the functions of wet and dry operation otherwise the result can be a container full of almost MUD which becomes difficult to empty and will be detrimental to performance. All machines are wet or dry and the change from one to the other is designed to be simplicity itself exchanging a dry filter for wet safety float valve and change of floor nozzle, or vice versa.
Although twice the capacity we have added a folding handle design allowing easy movement when in use whilst also allowing compact storage. The accessory kit provides tools for both wet and dry operation with stainless steel tube sets as standard.
Q. Does this machine work in the same way as a Karcher Puzzi 100? I've used the Puzzi until now but it has stopped working. I'm considering replacing it with this Numatic machine.
A. This machine doesn't work in the same way as the Karcher, while it is a wet pick up vac it does not lay down water as a carpet cleaner would do.
