I purchased my first unit at our local [@]. I used it 4, maybe 5 times. When it worked correctly, it was an amazing cleaner. After that, the water and solution would disappear just as fast as I could fill it up. Just pour out on the floor and it was gone in 30 seconds. Hoover was wonderful and replaced the machine. I only opened the new one a few months ago, due to not having a need to clean anything until spring. I got it out, opened it, set it up, cleaned my carpets no problems. Did it again a few months later (grandkids) worked fine. Cleaned it and put it away. Bought a used recliner and cleaned it, worked great...then wanted to spot clean the livingroom...boom...tank problems again. As soon as I filled it and started it, the clean water and solution sucked right down into the dirty water holding tank...gone. Ugh! Couldn't believe it! I have never stored this with solution or water in it, have always wiped the seals dry..I think this model just has issues. There was a lady returning one to [@] in front of me the other day, saying it didn't work. Should probably discontinue this particular model. Seems it has a lot of problems. But, I contacted Hoover again, feeling a little crazy with it being the second machine, but again they were happy to assist me, no hassles, customer satisfaction minded, and offered again, to replace it with the model of my choice. Thank you Hoover!
