This is our second SpotBot and I love the hassle free automatic cleaning. It has done a great job cleaning up the spots so far over the last couple of weeks. We had an older unit a few years ago and the hose broke on that unit as some of the reviews pointed out. However our unit got very heavy use so I was happy with how long it lasted. I'm anticipating this unit will last much longer since I don't anticipate using the hose as much.
