DustBuster blows out air from motor - Black & Decker AV1200 DustBuster Handheld Vacuum

The only thing to do is to replace the damaged motor.
Probably more cost efficient to replace the complete machine.

(The below worked with my 9.6v version - I assume the others in the pivot range will be similar).
If you open the lid (where the dust collects) you can twist the inner plastic filter about 30 degrees to unlock it. Then, with a bit of "fiddling" with the fold out part (press the unlock button and rotate the suction part as if you were going to use the unit) then, the plastic internal part and the whole suction bit will come off the motor part. Do this slowly as the inner filter will be full of dust and muck. You can then take the filter out, tap it clean in the bin and then wash and dry it with washing up liquid (gently) and allow to fully dry before putting it all back together again.

1) Test the power cord
2) Test the belt is worn and replace it
3) Test the motor need lube, and repair.
God bless you

I have bad news. That part is no longer available; check out the info here:

I actually have exactly this kind of dustbuster, and I was able to renew the battery pack, but I had to do it by using eight individual cells and soldering them together. The size of cell (I think it's called a sub-c) is not common to consumers, but is fairly common to battery pack manufacturers. Quite honestly, your dustbuster with no battery is worthless, even when it was available, the pack was $46.46 as a spare - probably more than the thing is worth. Buy a new one from wal mart! If you really, really want to look at getting a new pack for this one, then your only option is to find a specialist battery store (I know there's one in my city) that can 'remanufacture' them. Basically, they take the old pack, and rip out the old cells, and put in new ones. They have the special equipment to weld the connections without frying the cells too, and they have access to Sub-C cells, of course. It'll be expensive. Good luck, you're gonna need it. Sell it at a garage sale; it looks nice.

The fliter can be tapped aginst a garbage can to release soil. Using compressed air outside to blow off remaining soil and dust. The manufacturer will have replacement filters available.

Black and Decker website offers product manuals. Also, various online vendors provided information I needed about DustBuster in product description, making it unecessary to purchase manual.

Leave it in the charger for at least 7 hours and then try and see if it works on a full performance time of roughly 3 minutes.

Hi,
There should be an area to press at the joint between the front section, and the motor section. The whole front cone comes off to empty the contents, and there is a filter - but no bag with these.

Hope this helps you.
Thanks for using Fixya
