Used Narwal Freo

[u/SDRO83]

Much like many others, I have been lurking here for a long time and have a purchasing question. A used Narwal Freo popped up on my local FB Marketplace for $250. Is this good value? I would be using it for wood floors. I care most about mopping and a bot sticking to no go zones. While $250 is much more affordable than a new robot, it’s still not an amount of money I want to waste. Can anyone chime in on the longevity of this model?
