Bests & Worsts Reviews from Amazon

Things i didn't know before i tried it. Maybe you want to know before too. 1. It does NOT navigate itself not to repeat the cleaning path. It repeated the same area again and again and running zigzag pattern. I thought the V5s has the navigation system thought I read it somewhere before. But never mind, I just moved it to the other spot. For the price vs. expectation level, I don't get mad at this. 2. you need to change to water tank when you want the wet cleaning mode. I though the V5s can switch from dry vacuum to wet mopping by itself. But no, I need to get up and lift the proper tank into it for dry or wet cleaning. Just try to be super lazy !!! hahaha Overall, it is quiet enough, powerful suction, it does a gentle job while bumping onto furniture. It moves from hard word floor to rug area without problem. I love it for its price is so much cheaper than Roomba 860 with the similar features with more (wet cleaning). I have just recommend this to my coworker and probably will order the V5 (model without wet cleaning & water tank, as my mom doesn't need that). Now my conclusion is : V5--- vacuuming, mopping functions but NO water tank for wet cleaning feature. V5s--- with above features PLUS water tank that need to manual switch from dust tank to water tank. I still give 5 stars even thought I think the description from Amazon is NOT clear enough to point out the differences between different models. Very misleading !!!!
