There is a lot of ground to cover here. To be honest, I am unimpressed with the R1s.

First of all, this isn't the best video - I was unknowingly out of storage space on my phone, so the video suddenly cuts off and I was not able to record any more. I was able to take a handful of pictures, of which are included in the video. I may plan an eventual revisit to better document these machines. 6 cents per container and the location-exclusive RVMs are a strong incentive for a revisit and retake.

The R1 is essentially a large T-9 with a bulk feed system - as Alex described it, "the R1 is a washing machine."
This specific machine that I used was having an issue with the compactor inlet sensors, where it was detecting an obstruction and constantly going into error mode. After recovering all of my bottles and moving to the second R1, things were smooth sailing. These machines seem to not like angled barcodes, hence the crushed cans and 8oz bottles being rejected - they were accepted in another pass. I also had a lot of weird containers that were not in the database, which is why so many were being rejected. After this initial load, I did the rest of my bottles in the E1s, which seemed to work a lot better.
Interestingly, The R1s are the only machines I've used with working weight sensors - they consistently rejected a bottle which had some water in it.

I do have a fair bit of skepticism towards these machines - note the can that was crushed by the machine (likely by the blades on the feeder system), which was undamaged prior. I also noticed that when someone before me was done using the machine, there were still some cans in the feeder system, which they had to reach in and remove. I'm not sure to what extent these machines verify that the chambers are completely empty. One of the E1s also didn't reject a container which should've been rejected, and another machine seemed to have lost a container (fell off the belts within the back room) that normally wouldn't have been accepted. However, the machine is designed to account for "lost" containers by design; when they are at that point, they've already been scanned and accepted. This means said container was either incorrectly scanned, or stuck to another can which prompted the machine to accept it as one single can. It's worth noting the machine will also go into error mode if too many containers are lost.
There's a lot of potential with this platform, but there's still a couple of bugs to work out first.

I was told that 3L Poland Spring jugs do not fit in the machines, which makes sense as they have the innards of a T-9.
I did test a 3oz Bang bottle in the E1 several times, and it was rejected each pass. I'm unsure if the machine could not read the barcode or even detect the container, or if it is not in the database. If I revisit, I will do further testing with the R1s.

The plastic compactors on these machines sound exactly like the old humming shredders used by Tx2s, which completely caught me off guard. They are also capable of handling hard plastic bottles, such as the vitamin waters.

Huge shoutout to the person managing the place, they showed me around the back rooms and I got to see all the inner workings of the machines, and were more than willing to answer all of my questions.
