This filter conversion kit is designed to transform your Milwaukee M18 vacuum cleaner (models 0780-20 and 0880-20) to use generic cloth filters. The kit consists of two main components: an inner support structure that provides volume and shape, and a robust locking ring that securely holds the cloth filter in place. By using a cloth filter, you achieve an economical and practical solution for your cleaning. The cloth is wrapped around the inner support and secured with the locking ring, making replacement quick and straightforward. Although a cloth filter may have a smaller surface area than a traditional filter, making more frequent changes recommendable, a single cloth is often far cheaper to operate. This kit is a smart way to optimise your vacuum cleaner's functionality and maintenance.
