I'm with You on not washing bags as I remember a few years ago I did in fact wash a cloth bag in the washer and it was ruined, so I won't wash any in the washer, now I just vacumm that out

this is a pic of a CA lux commercial vac which is very rare as most die hard lux collectors are looking for this vac, I have been told by a collector who has one that they do an awsome job of cleaning
