I own the Little Green portable cleaner as well as an upright cleaner. I like the Little Green one because it's easy to grab and go for those quick, unexpected messes. The water reservoirs are easy to fill and clean. It has great cleaner coverage/spray and the suctioning is powerful. All in all, it does a great job getting the messes up. However, this is the second one I have owned. My BIGGEST complaint, is that there is no way to completely take apart the brush/suction head and stuff gets stuck and gunk gets trapped in there and the way it's angled, there is no way to get it out. Doesn't matter how much water you run through it or soak it etc, there is just no way to get it completely clean. Which drives me crazy! I had hoped that this being my second one, that would have been an improvement someone made. Especially since the brush head is clear and you can actually SEE the things trapped.
