Can anyone recommend a vacuum cleaner that will take care of fine floor dust (dirt) without quickly plugging it's filter?
I have two vacuum cleaners right now, both Rigid. They work well, but only for short times because the filters don't last long, not to mention the replacement filters are quite expensive.
I've tried cleaning the filters with air, and then in soap and water with a lot of mess and little success, having stopped short of running them through my wifes washing machine.
I've tried the paper bag option over the pleated filter, but then you don't get 5 minutes run time before they plug.
My best success so far has been to vacuum a bit of sawdust from under the table saw so as to put a sawdust coating around the new filter and then I get better life out of it, probably an hour or two.
Floor dirt here in the desert country here is awful. Comes in on muddy shoes and vehicles tires and you can't sweep it with a broom without most of it going into the air.
Madwilliamflint had a thread started on Vacuums earlier this month, but before it got to my problem the thread lost momentum.
Any ideas? My best vacuum that I ever had was an old Rex-Air that used a water bath cyclone for a filter.
