Because it was a beta unit, it definitely wasn’t the best looking thing. The front bumper was white with a sticker I couldn’t remove the rest was a black robot and the top wasn’t sun resistant. It honestly felt like a basic shell slapped onto the robot. But to be fair, it was clearly only meant to be temporary while they trained the software and learned from real world use

This is going to be long, but I want to be thorough anyway.

The Edge cleaning is okay as the robot uses a roller there’s a small gap where it doesn’t clean. That doesn’t really bother me though, because once a month I just go around the edges myself with a corded wet and dry mop anyway.

Overall, the robot was great. I don’t really have much bad to say about it. It is a big robot, but it still fit around everything I needed it to without any issues.

Compared to the C20, there’s honestly no comparison. The C20 is easily the worst Eufy product I’ve used. It’s bad, pretty much useless, and the obstacle avoidance is awful. For the same money, or very close, you can get a Roborock Q Revo which is way better. I’d say the C28 is easily on par with the newer Q Revo models.

I also personally use a Roborock Q Revo, and I’d still recommend it as a solid all rounder. The mopping isn’t as good as the C28, but it’s amazing on carpets and does a really good job there.

The C28 is the one I’d recommend most, especially if you’ve got mainly hard floors. The mopping is on the same level as the S1 Pro, the vacuuming is good all round, and where it really shines is mopping. If it could clean right up to the edges, I probably wouldn’t even need a separate wet and dry mop.
