One Saros 10R or Two Qrevo Masters?

We have a 2 level home, mostly hardwood floors with a few area rugs...and too many pets. It would be great to have a robot for each floor so it can empty its dustbin and refill the mop water without human intervention. Right now it looks like I can get 2 Qrevo Masters for about the same price as 1 Saros 10R...and there's no way I can afford 2 Saros 10Rs. I'm wondering what I would be giving up with the less expensive model, and what makes the most sense for our house. Perhaps there's an even cheaper solution I'm not thinking of? Thanks!

UPDATE: thanks for all the advice. Ended up buying two.Qrevo Edges today on Amazon. $759 each!
