The WV470 provides a larger alternative to Charles, with twice the capacity - the same high performance standard, be it wet or dry. All WV machines are wet or dry and the change from one to the other is designed to be simple – just exchange a dry filter for a wet safety float valve and change the floor nozzle. It is important that you do not mix both the functions of wet and dry. The result can be a container full of almost mud which becomes difficult to empty and will be detrimental to performance. • 2 Year Warranty • 27L dry, 20L wet capacity • Folding handle for easy storage • 10m cable • Full accessory kit including: • 300mm MultiFlo dry brush nozzle • 300mm MultiFlo wet pick-up nozzle
