Question: I purchased this in Jan 2014 and already it only holds a charge for 1 minute if that.  Does something need cleaned or is it just another piece of junk
Document: I was horrified when this came in the mail. I got it out to use it and it spit out dust upon starting it. I tried using it to clean a small area and noticed it wasn't picking up anything but dust kept coming out. I opened it to see what was going on and was disgusted. It already had quite a bit of junk in it and the filter was completely gray, almost black, with all kinds of hair and lint on it. It was obviously used and not cleaned.
My mother purchased this vacuum for me for Christmas. I wanted something small to clean up dirt around the house or my car. The vacuum supposedly had great, improved battery life compared to it's earlier generations. Not. True. The battery after it's first charge lasted 10 minutes. After a year, I'm lucky if it has it's full power for a minute. I contacted the company and the battery is irreplaceable. I attempted to let it die out and recharge it with no improvement.
I've had this vacuum almost a year now and it is great! I have a bird and it sucks up all the feathers like a piece of cake! I keep it plugged in all the time and it always holds its charge longer than I need it. I would highly recommend it!
Poor pickup due to lack of vacuuming power. Not sure if there is a cordless that works as good as a corded but this model doesn't come close. Rarely use this due to it's lack luster performance. Had hoped to use it for our cars but it is just is not up to the job, now it is just another piece of junk that I do not use but do not throw away because of what I paid for it.
We purchased another brand of hand-held vac at Lowe's, and it had very little power and lost its charge very quickly. The Dirt Devil has great power and holds a charge for a very long time, plus recharges quickly. We highly recommend this product.
Not happy with it..has to be cleaned constantly...very difficult to clean ..the last one I had for many years had a cloth filter which was more efficient..this one looks like cardboard which is not easy to clean. Filter is bent inward and most difficult to clean fil. I need to be much too careful to clean it as it does not look like it will last. I do believe I would not purchase another Dirt Devil
Another review states that the wall mount isn't very secure. All I can say about that is the if it is mounted properly on the wall it is very secure so there is no real issue with that.New thoughts: I don't use this product very much but I've found that if you need to run it for more than a minute or so it is pretty much worthless. In a very short period of time the suctions drops to almost nothing.
However, I love the DirtDevil and it will be my vacuum of choice for the future. I already own a DirtDevil upright and it is a great machine as well, but I purchased that years ago at Target. If your looking for a mini vac with good suction and stamina, this DirtDevil AccuCharge seems to be the real deal. I will follow up with another review as time goes by.
Not a good product, already in the junk pile where it belongs. Would not charge or operate after a short time.
This product would be good if it could hold a charge. For the first few months it was great, but after a year, it is  a piece of junk that barely picks up because the battery never seems to be fully charged. Don't waste your money.
Answer: The answer is simple.  You bought it in January of 2014.  It doesn't work.  It's defective.  Call their customer service number, have them mail you a return label, return it, and either get a refund or a new one.  I just purchased one.  I expect it to  perform.  If it doesn't, I'll return it.  I am not shy.  Money is money.
