I used my first vac 6 times before it started shutting off after 3 sec. I notified Tineco because I was one week out of Amazon send back. I have used hoover floor jet, Koplens and Bissil wet dry vacs. No experience with Bissil crossfire.I was impressed with being able to contact customer service by phone with no wait time. They requested a video of the problem which is reasonable but for me hard as I am 84 y/o and not technically proficient. Customer service answered my 4 phone calls promptly and sent me a new vac promptly. The machine is fault free in use. I have porceline tile. In short I give 5 stars to machine and customer service. I hope this keeps up. I will update after more use. UPDATE: I have never written an update on anything but due to the product quality and the customer service I feel the need. No product lasts forever but it was nice to talk to humans and send your vac back and get a new one postage free. My replacement $300 Tineco 3 is working great after about a month. Wish I could put this under 1 star so peeople will read it. I mostly read only the bad reviews as god ones are often too numerous.
