I'm gonna paste the same comment as I made on the repost made today, as I'm curious if anyone has experience with this brand.

What truly makes or breaks a robot vaccum is the software, and most aside from a couple brands get it horribly wrong. The cleaning/obstacle avoidance algorithms can be the difference between an amazing and a useless vaccum, and so can the useability of the app. It's why Roborock is still so far above everyone else. I'd be afraid to waste my time and money on this no-name brand that could have terrible software and/or an app that gets abandoned after a few months making the vacuum useless. I could be wrong, as I don't know anything about this brand. Anyone with experience?

I've been using a Roborock S4 Max for 4.5 years now, and it's been flawless. Looking into upgrading to something with obstacle avoidance, as I have two 4 month old puppies, so keeping obstacles off of the floor is a fruitless task. I've relegated it to manually running the vaccum after I pick things up, as opposed to allowing it to run everyday while I'm gone, which I'd prefer. That's why I'm browsing these posts. I'm all for finding a cheaper brand that works just as well; I'm just sceptical, which is why I was curious about anyone with experience with this brand.

Roomba is a pos for mapping, avoiding or anything. I think the programmer was drunk when he set up the algo

Agree that the software is key. The Wyze branded Xiaomis from years back did a pretty good job, I find.

I got one on clearance at Walmart for like $45 a few years ago and it's worked really well for me. I use it in my 500 sq.ft finished basement. It occasionally will get stuck under a recliner if it drives under it at the right angle but other than that no complaints

M505JZ2F still seems to work. If you're using the Amazon app you might be missing the step of tapping on the arrow that appears in the promo code box to apply the code (before tapping the Continue button).

I bought this exact vacuum a few weeks ago and returned it. Essentially, "you get what you pay for". I bought it for a dedicated room, while I have two 6-year old Roborock's on other floors. The obstacle avoidance was decent enough for $100, but it seemed to get lost relatively easily. It also didn't have great suction - after running it through the room a couple of times, I ran a Roborock S4 in the same room and it still picked up a decent amount. Oh, and it was loud for the mediocre suction. Even at only $100 I couldn't stand it. Picked up a used RR a34 for $60 and it is much better.
