Many come with their own little collection baggy or canister, but they fill quickly and still don't do nearly as good a job as the powerful suction from a shop vacuum.

The suction pressure was running 20psi.

hey guys...been waiting to hear some from local guys...im in reading, grew up in medford...ive bought 3 three deckers this yr in lynn...and will be buying more if i can find a good hard money lender...i go w/ suction 8...i believe thats the way to go in the lynn, lawrence, lowell and other tough areas...for me its all about cash flow...benn buying 3 deckers for about 200K, not overly distressed but bank owned and put 10K into each unit and rent for $1200-$1500...

It's possible that you can get a port-a-potty company to come out with their truck and suction it out.  

As@Roman M.mentioned, Mtg foreclosure auctions and Tax Deed suctions are two completely different animals. 

@Victor Morales in my county some notice of sales say they are suctioning off the “property or a lien” and it’s ambiguous which one.

Plus, check the draw or power or suction of the fan....single piece of toilet paper held close will should be aggressively drawn to exhaust fan. 

My home has very high vaulted ceilings, and use a telescoping pole with a suction cup on the end That I found at a box store to change the light bulbs.  

Something like this might work, I have also seen wet dry vac attachments people have made with the blade attached to the suction end.
