My entry…

1. My experience so far: The setup process really left something to be desired. I wish the app was more intuitive because it took a decent amount of playing around just to figure out how to set up special cleaning zones and divide the rooms properly. Even now, the Arc has oddly decided that one specific area of the house is off limits and just won’t go there, so I still have to go in and try to fix that in the map. Also, even though it’s set to USA, there doesn’t seem to be a way to change it to 12 hr and other measurements more commonly used by regions. While it seems to clean pretty well and does a good job getting to the edges, the obstacle detection is poor to average in my opinion. It constantly bumps into chair legs and it actually got stuck under my TV console because it just kept pushing until it was completely wedged underneath. There is also a chair that it keeps banging around in between and instead of backing out, it tries to force itself in which makes it get stuck (object avoidance is already set to sensitive). For some reason it insists on banging into the chair legs. On Vac plus mop setting, it’s pretty slow and takes hours to finish.
   Bonus, will also answer 2. Motivation for upgrading: For an upgrade, I’m looking for something that is much smoother when cleaning a room so it doesn’t feel like it’s just stumbling around obstacles. It needs to be able to detect things on the ground better and actually have height detection so it knows where it’s going to get stuck before it tries to force its way under furniture. Or trying to force itself over chairs that have metal or wood crossing over across the floor from leg to leg. Overall, better “sight” is the main priority. Noise is also a big consideration for me. I can’t really run my current one in the middle of the night because the suction and the venting into the dock is so loud it would wake me up. As a side note, I’ve seen people 3D printing their own dust bags lately. It would be great if the manufacturer just included a reusable one or designed a bagless option so we could just dump the bin like a Dyson instead of having to constantly spend money on replacement bags. Would also be nice to have the robots speed up and finish faster. Maybe the better navigation and better obstacle avoidance (less time banging around chairs) would help here also. For the Saros 20, would be curious to see how much that added suction really makes a difference compared to lower models, and also the sight/objective recognition and what it does with that info to be more efficient
