Bests & Worsts Reviews from Amazon

I purchased the Shark IQ to replace a NEATO that finally, after many years and cycles of service, went to that robot vacuum cleaner home in the sky. The Shark had some big shoes to fill, but I was confident that, with the advertised features, it was well up to the task. I was, sadly, disappointed. There are two features in a vac that are important to me. First, and most obviously, it needs to clean well. I have a black cat that leaves her fur all over the place, and a 14 year old son that's not much better about leaving a various crumbs and etc. The second feature is that the bot return to its base and resume when needed. Our house generally will take two cycles to get through because of the layout and size. Another important aspect for me was the ability to control the bot remotely. The application and wifi connectivity that came with this particular model fit that bill nicely. Finally, I needed it to be simple. In my life, I've learned that if devices are complicated, I am quickly consumed as tech support because it comes down to me having to answer questions, fix this that and the other and, frankly, after all of that, I'd just as soon get out the upright and go to work. First, the good. Our Shark was methodical and cleaned like a pro. I watched some of it's early cycles when it looked like it would miss an area only to return and make sure that a spot was cleaned well. So, as for cleaning, no complaints. One down. Setup was easy and the application and remote control systems seemed fairly simple but, to be fair, because of the next section, which I will call "Fatal Flaw", I don't know how much long term ease the application provided. Our Shark, whom we affectionately named "Sharknado", suffered a fatal flaw...it never once found it's way back to the base. I ran it often in hopes of getting it to develop a map of the floor but it never made a full cycle so there was no way for it to ever get a map developed. After every run, we would play "Find the Shark" to see where it had died. Even the application that should have alerted me to it's presence or distress was also not to be counted on. With this, sadly, we will part company with Sharknado and search for another to fill our home with the buzz of a busy robot vacuum cleaner this year.
