I bought a Bissell pro-heat carpet shampooer, and it stopped working after 3 uses. I exchanged it for another one at Walmart, and a year later it isn't working. Walmart no longer exchanges or refunds money for Bissell shampooers. I called Bissells customer service, and the problem was more than a trouble shooting problem that could be fixed on the phone. I was given a repair service for my location, called them, they said they have a flat rate charge for fixing Bissells because they continue to break over and over, and the repair people cannot work for free. I asked what I should do, he said don't ever buy a Bissell.
