Bests & Worsts Reviews from Amazon

Here's the situation. I have an open floor plan which appears to mean utter and total confusion for these robot vacs. The last one I had literally got so befuddled, it would just stop in the middle of the room for no reason over and over then would clean the same three foot by three foot area before the front door ten times over while missing entire rooms. I researched robot vacs a lot. Specifically robot vacs that could handle carpet and had strong suction. The Roborock E4 kept coming up and it was on sale so I went for it. It was a little rough at first. "The Rock" as I call it got caught up on every area rug or throw rug I owned due to the little silicon sweeper brush getting caught on them. I removed it and had no more issues. It cleans in a diagonal pattern which at first seemed a bit odd, but it is thorough. The first few cleanings around the house, it bumped into everything hard and sometimes bumped over and over as it tried to figure out it's way around. By the fourth cleaning, it seemed to get smarter and was no longer going over certain areas too many times. It now had a routine it followed of which room to do first, second, etc. With every cleaning after that, it got faster, more efficient and bumped into much fewer things. I'm now able to trust it to clean unsupervised. It doesn't get lost or caught up on furniture and after, it returns to it's charging station without issue. It's run once daily and so far in the several weeks I've had it, I haven't had to perform any maintenance on it apart from emptying the dust bin and cleaning the filter each time. And I have to state that the suction on this thing is amazing. You can max out the suction through the app, but I find normal suction to be sufficient. I can clean with my full size vacuum and then let the Roborock go do it's thing and it will come back full of dust. The battery life is also excellent surpassing my Shark. As for the app, it has become glitchy and is often unresponsive on my device. The map it draws after cleaning is invariably inaccurate so apart from being able to adjust suction, I'm not sure there's a need for it. I rarely use it anyways choosing to instead utilize the buttons on the top of the vac itself. I'll update my review if my opinion changes, but so far, I'm pretty impressed by the E4.
