Snow Joe 4.8-Gallon 4-Amp Ash Vacuum

The machine (ASHJ201) worked fine, twice. I say fine because it vacuumed up light ash from my pellet stove and didn't blow it all over my living room like my shop vac. It was not strong suction and I can see why some other reviewers may have had a hard time getting it to work on their pellet grills. The second time I used it, I noticed an electrical burning smell. The next time I went to use it, it wouldn't turn on. I ran through all of the troubleshooting from the manual, but nothing got it going. I called customer service and, though I did have to wait a while, I spoke to a very nice representative who asked a few questions and then processed my return. I asked for a refund as I didn't want to bother waiting on another machine which might just burn out again. I would guess that the motor is underpowered and overstrained with the extra filtration. Yes, it's a pain to box it up and go to UPS, but I'm happy they are taking the return and refunding my money. On another note, and this is not Snow Joe's fault, the accessory pack that Amazon recommends with this item does not fit, it is for a smaller machine.
