Portable vacuum prefilter prototype for 99 cents!

[plauale]

Laugh your heads off, it even has duct tape! However the functionality is impressive, I needed a mobile solution to clean out 100years of mice turds, dust, and rotten wood in my attic:

1- it pulls more dust out of cracks that i had previously passed over with a standard wet/dry shop vac with pleated paper filter (had to it off every 10min)

2- The first 1/2 hour of gentle sawdust and dust vacuuming the filter was gray but no accumulation, the bucket had 2 kg (~1lb) of junk.

3- after, I hit thick piles of turds, old bits of insulation and chunks of plaster for 1/2 hour, the filter has 100g of dust and the bucket had 3 kg of junk.

Pretty? Durable? NO
Useful? Portable? Yes
Efficient? maybe

quasi-specs: vacuum is a heavy duty Miele (~2000W) that refuses to die w/ 1.5" inlet, 10" separator bucket (unfortunately with a taper in the opposite direction than desired, so there is a permanent spin of fines in the top corner), semi-rectangular transition from a 1.5" inlet shop vac hose, and yes, a cardboard baffle plate suspended by the threaded rods.
