Any suggestions about robot vacuum and mop combos?

I have to admit I really like the reviews of the Dreame X40 Ultra but I find the $1700 price tag to be a bit much.

I see some vacuum only models for as little as $300 and everything between $300 to $1700.  I am wondering where the sweet spot is?  I don't need a top of the live model as that seems like a waste of money. The feature options are pretty long and difficult to really figure out what you need and don't need. 

Does anyone have a robo vac?

I have heard good things about this one.  Several reviews claim it is the best budget model.

This seems to be a good breakdown on features and comparing models.  Plus the review is only a week old

Roborock Qrevo Master seems to be the one to buy.  Currently it is available for $1199.99 on the Robotock website but I will wait and see if Amazon has a sale on Amazon Days October 8th and 9th.  If not I will still buy but I am hoping for a discount.

I decided on that one due to excellent reviews, superior path finding, better cleaning ability, and the fact that it does both vacuuming as well as mopping.  Which is important because my house has both tile floors and carpeting in rooms.
