Question about Roborock Qrevo

Yes.

Advantages:
- Mop part in the dock much easier to clean (simply remove and wash off).
- Experience shows that the mop is even a little more thorough.
- Half as expensive.

Disadvantages:
- Obstacle detection significantly worse.
- More problems with hair than a vacuum with 2 brushes.
- Cleaning/emptying intervals for mops and bags are not tracked in the app.
- Allegedly worse performance on carpets (but not true according to some YouTubers).

If you don't have a lot of stuff lying around or a very hairy household, buy the Q Revo and treat yourself to something nice with the money you saved. Have fun.
