I was in Erie this winter and we're planning to go back! I actually used to own a Husqvarna dealership (I had an Ariens 28", myself), I will have an EGO 2 stage, but don't use it anymore since the Snowbot.
I'm guessing that's about 2 feet of snow...that's what we faced in our last test in Andover, MA on 01-29-22. The Snowbot handled it really well, but it was also dry snow (a lot of it). I had no problem keeping up with the storm, even during the 2 - 4 inch per hour periods.
We are improving the performance in wet snow for the retail very launching soon (actually we're improving a lot of things).
As for someone stealing it...first when you lift it up past a certain point an alarm will sound. Second you will get notified via the app if the Snowbot leaves your property, this is done via GPS. Lastly you can follow your Snowbot for a very long period of time (days), even if someone turns off the main switch or hits the "emergency button", so you call the police, provide the location information and have it recovered.
The alarm should really be enough to scare most thieves away though!
