This 32x74 controller is highly configurable, which means it requires a lower number of product codes. The input can be programmed for temperature sensors, resistance thermometers and thermocouples, but also for pressure transmitters, humidity and flow sensors. The algorithm for heating-cooling PID control is optimised both for temperature control and for process variables with quick transitory, like pressure control and flow control. The software functions of the ATR121 include the open-close logic for valve control on industrial thermoregulation, air conditioning, dosing systems. The controller's outputs can be selected as command/multiple alarm modes/event. The serial communication option is RS485 with Modbus/Slave protocol.

Absolute worth the money
Size: 11S MAX
The RoboVac works well for me.
Very easy to use, not noisy, easy to empty dust collector out, picks up dust and crumbs etc. better than expected. It works on its own from room to room and transitions just fine from hard to soft surfaces. It even manages my higher pile carpet in some rooms. It‘s not heavy, so I use it upstairs and downstairs, just carry it up or down, plug in and start it. Easy!
It works best if you get all cords and anything that it could caught up in out of its way beforehand.
Sometimes it gets itself ‚ worked up’ and goes over one area several times which is weird.
My house ist quite big and if it works over one area over and over, it does not have enough battery life to do the entire ~16000 sqft. floor on one level with different rooms and changing surfaces (I expected this, no prob. for me).
The vacuum results are not as good as using a Miele canister vacuum ( my other vacuum) but good enough so the Miele only has to be pulled out from time to time for a deep vacuuming.
I would buy it again.

Customer service –4 stars. Vacuum, 5 stars
Size: 11S MAX, Size: 11S MAX
I received the wrong remote control for this product. It doesn't work with the vacuum at all. I called Eufy customer support twice. The 1st time, after I told them the issue with the remote, they would put me on a 3 minute hold, come back and ask me the same question. This happened 3 times. They then asked me for my email address so I could send them the picture of the remote. They told me to stay on hold but the call disconnected and I never received the email to send them the pictures. The 2nd time I called them I told them the same issue with the remote, they put me on a 25 minute hold and they never came back. I instead received an automated survey message to let them know how they did. They did poorly. Massive waste of time. I didn't want to return the whole vacuum just because of the remote. It's refurbished and the vacuum itself works very well! All I need is the correct remote.

My favorite robot vacuum! Works awesome!!
Size: 11S MAX, Size: 11S MAX
Eufy is by far my favorite robot vacuum brand we had one for several years and it did amazing with everything from dust to hair and even rocks didn’t phase it! It is super easy to set up, turn on, the settings are very user friendly and emptying the dust bin is super simple! They are very powerful but also compact and can fit in smaller places so that’s great for us and even when I don’t think there’s much on the floor it always gets full! You honestly can’t beat the price for how great these awesome little vacuums work definitely get your value for your money! I was a little skeptical getting the refurbished or Like-New one but I am super impressed so far! So grateful for tools like this to have around that are great at lending a hand 🤩

Sort of OK Budget model
Size: 11S MAX
I'm giving this model 5 stars because at this price, especially "renewed," it's a great robo vac. It is NOT anywhere near the hands-off level of other machines. It can't map the rooms, bumps its way around fairly successfully, but needs frequent hands on to fix something. In my case, with 2 long-haired cats, the most frequent issue is tangled hair in the roller. The machine stops dead and sends out 4 beep distress sounds for a while, then shuts down. Also, the remote seems to work only in line of sight, so if Eufy is stuck somewhere you can't see, and you were out, to find it you'll have to hunt with your eyes. Nevertheless, if your funds are limited, top choice.
Update: After 6 months of usage, I'm giving it only 3 stars. Problems: 1) if you have long-haired cats (I do) their hair clogs the roller fairly quickly. After a while, no matter how well you clean the hairs out, you have to replace the roller entirely as hair seems to get inside it and cause the machine to stop working entirely. 2) the remote works only if you can see Eufy and it can "see" you. If it gets stuck in some place out of sight, lots of luck finding it. 3) when told to go to home base and recharge, it bumps around for a long time trying to find the way home. Bottom line: Where it vacuums the rug/floor is clean, but it takes a lot of baby sitting. Definitely not first choice unless funds are really tight.
