Bests & Worsts Reviews from Amazon

5/2022 update: company reps have continued to plead with me to accept an updated unit free of charge in exchange for a five-star review. I stand by my original review (which was three stars before all this). You should be skeptical of reviews offering high praise for this unit, and make your decision based on available facts. 6/2021 update: the company recently contacted me and offered a bribe contingent on changing my review to five stars. I declined and I'm lowering my rating to one star. I guess you should keep that in mind when considering the other reviews you read here. They may be biased. --------------------------------------------------- Overall, a fair value for the price, but you can’t expect too much either. Marginally good cleaning ability. Has two sweeper brushes to guide debris under the unit to be vacuumed up. No rotating brush under the unit to clean more thoroughly. Pretty quiet though. No navigation capability, it simply bumps into objects and and veers off in another direction. What does that mean? The room you turn it loose in may eventually get clean, but you have to hope that it manages to randomly pass over all areas of the room, which could take quite some time. Also, due to the lack of navigation capability, it had a very difficult time finding its way back to its charging base. I could easily imagine the unit running out of power before reaching base. Would never connect to WiFi despite multiple attempts on the part of support to help. This seems to be a known issue, based on what I’ve seen in other reviews. Can’t comment on any of its connected features as a result. Ultimately I ended up returning it, as it had little value beyond being a novelty for me. I will credit it for helping me understand that the concept was good however. I ended up buying a more fully featured unit with navigation and better cleaning capability. I paid considerably more money for it, but it truly works works as an effective, labor-saving device.
