This is our 3rd Bissell machine and the best so far. The last one, (a Proheat 2X) lasted 12 years and could possibly have been revived again, but we decided to try a newer machine and we're glad we did. This model came with a good selection of tools and several samples of cleaning fluid, is much lighter than its predecessors, easier to fill and empty and much easier to clean after use.
The most important bit, it does a great job of cleaning the carpet! (We have two large dogs, so a good cleaner is essential). Expect to have to fill / empty the tanks 3 or 4 times though on deep clean mode if you have a dirty carpet, maybe more in a large room, but bigger tanks would obviously mean a heavier machine. I think we probably killed the last machine by not rinsing it out thoroughly after EVERY use, so we'll try and look after this one a bit better. Time will tell, but if this one lasts another 12 years, we won't be complaining!
