Bests & Worsts Reviews from Amazon

I work in industrial robotics and motion control so I might have different expectations for gadgets like this. I've owned 3 of the original, better well known robot vacs and I always felt like none were really engineered to work in a real family environment (area rugs, pets,kids, etc...). They've always been noisy and not overly effective. They've seemed more like a "look I have a fancy robot thingy" gadget than an effective tool. They broke easily and weren't easy to get running again. I saw a review combined with a low price alert on one of the many gadget blogs I read and I accidentally bought this thing... I'd put it in my shopping cart so I could look at it later when we placed a quick order for something and didn't look closely at the contents before finishing the order. i was prepared to ship it back, but I can't let a gadget be that close to me without checking it out. The design looked good and seemed like something I needed to play with. The big button on top was taunting me... I've run it every day since. It's quiet and the amount of dirt, hair, etc... it picks up every day freaks me out a little. We surely sitting in the middle of that much dirt all this time. It easily navigates over the area rugs including the one with the tassel thingy on the ends with ease. I'm pretty sure the algorithm for moving around objects in the other robot vacs was better, but the algorithms don't mean much when the gadget can't effectively do its main purpose. I have 3 unused for probably more than a year vacs disassembled in my shop...and they're going in the recycle/garbage bin (after scavaging a few useable things). Thank you Eufy for showing me how a robot vac is supposed to work. I threw away the box....this was a happy accident and it's not going back to Amazon.
