Query: Broke after a few uses

It did a good job of cleaning, but it stopped working after a few uses. First the lights stopped working which tell you whether it is warming up or ready, then the whole thing stopped working. It is the last Shark product we will buy. We had a sweeper, and it wouldn't hold a charge after a short time.Their products are inexpensive so they are attractive, but you get what you pay for. STAY AWAY.
