Is the Roborock Q5 Pro a good value compared to premium quiet vacuums?

The [Roborock Q](https://www.amazon.com/s?k=Roborock+Q&tag=wehavethat-20)5 Pro costs $449 versus $900 for the Dreame L10s Ultra — that’s $450 saved while still being quiet enough for most households. Half the price for comparable quiet.
