Australian looking for robot vacuum + mop recommendations ($500–1200)

I’ve got a 3-bedroom house and no pets.

Looking for a robot vacuum with mopping. Budget is $500–1200AUD.

From what I’ve seen, Roborock seems to be the most recommended, but I’m not sure which specific model is best in this price range.

Priorities:

• Good vacuum performance on hard floors and carpet
• Effective mopping
• Reliable navigation and obstacle avoidance
• Low maintenance

Would appreciate model recommendations and any experiences. Thanks!
