Roomba S9+, how does it hold up today?

I’m looking at finally getting a robot vacuum, to try and defeat the eternal shedding of my dog. I don’t want to spend too much now, but have found a Roomba S9+ for $200.

I know the model is a few years old now, but it has gotten excellent reviews when it was released.

How does it hold up today? Are there models retailing for $200 that can match or even beat it?
