12/29/2024 Update: After some time with this robot, it is still working great. The app prompts when it's time to clean (wipe sensors, clean filter or replace parts). I just did the first cleaning of the bin and filter area (still 10 hours left on the original filter). I have a replacement part bundle waiting for when it's time to actually replace something. No issues other than the app messing up the map (twice so far) which is easily restored from a backup (the fact that they have backup as an option tells me this must be something they expect to happen). It also was having LDS (the spinning sensor part, I think) errors, solved by cleaning around that part. I am still blown away by how much stuff this picks up compared to every model Roomba I have had. I bought the very first Roomba model when it came out, and have been using various models of Roombas ever since. I have three currently, with the newest one being a self-emptying S9+. This Yeedi is so much better, so let me get the only negatives out of the way first: 1. The C12 Pro Plus is listed as being able to climb over a .7" bump. My threshold between hallway to kitchen is more than that, and the C12 gets stuck there. Sometimes it will make it over, but it won't go back (probably a cliff sensor reacting to the black rubber transition strip we hav there). Workaround: A mall mat. After that, no issue. (Roomba can make it over this, but two other non-iRobot 2. The C12 has multiple levels of vacuuming power. On the highest level (a tornado icon), it pulls up the light throw rugs from the kitchen floor and gets stuck on them. It has no issues with any of the heavier throw rugs. Workaround: Yeedi lets you adjust the suction power by zone, so I just dropped down the power when doing the kitchen. After that, no issue. (Roomba has no issue with this, probably due to its much weaker suction.) Everything else is far superior to any of the iRobot devices I have had -- even one that cost twice as much as this Yeedi! Epic features: 1. The station uses a bagless bin that the robot empties in to. Not only does this save money (no bags to by) but you can easily see when it needs to be emptied. It gets handfuls of pet hair and fluff every time, even after the Roomba has been ran. 2. The mapping is so fast. It just drives around while the little spinning sensor on the top (Lidar? maybe?) figures out where the walls are. The map it produced was much more accurate! It also figures out where rugs are and represents them on the map after a job. 3. The app shows the route the Yeedi took! If you set it for 1-pass, you see a smart zig-zag pattern. When you set it for 2-pass, you will see it does a criss-cross pattern. While vacuuming, the app shows where the robot is in realtime. Fascinating to watch! 4. The robot has a pop-off side brush for easy cleaning. No need for a screwdriver! And, I have yet to find a bundle of hair under it, like the Roomba seems to do after every few cycles. 5. The brushes have some kind of magic. The Roomba needs regular cleaning where you remove the brushes and pull balls of hair from each end, and cut strands that have wrapped around the brush. After 30+ hours of using the Yeedi (in a two pet household), not once have I had to do that. HOW is this possible? 6. The app lets you send it to just a specific room, or tap multiple rooms just to do them. Current higher end Roombas have this feature, but the Yeedi app makes it much easier to actually use. ...and so much more. The unit backs in to the dock, announcing that it is charging, then emptying the bin, then will resume after that. It navigates very well, around objects, slowing down before hitting things. Whatever they are doing, it is very advanced and not at all what I had expected from a brand I have never heard of. And it mops. I have an iRobot Baava robot mop that has an advantage of being much smaller (it will fit between the toilet and the wall). The Yeedi has a mopping bin (remote the dust bin, fill the mop bin with water and plug it in). It does not use special pads (it comes with two Velcro-on reusable pads). It does not do any soap -- just water -- so the Braava might be doing a better job. BUT, after letting it run one time, the pad came back dirtier than I've ever seen the Braava's. The mop also vibrates as it goes, much more intensely than the tiny Braava. GREAT SUPPORT: I have written their support a few times, asking about issues with the threshold (they suggested the mat) and the carpets (lower the suction). They have been very helpful with suggestions, and respond within day. I went in to this highly skeptical that it could be any good. At half the price of a high end Roomba, I expected half the quality. After 30+ hours in use (then the app teaches you where to wipe down with a cloth to clean sensors!) I am not 100% convinced this is the best vacuum robot I have ever had. (I do not have enough experience with robot mops -- but have owned the Scooba and Braava.) I think that's all I have to say. I am blown away by how good this unit works. If they could make it handle larger thresholds, that would remove my only real nitpick. Kudos to Yeedi.
