Question about Xiaomi G9 Plus

As has already been written, 10 minutes at level 3 (actually the standard level for me) is just enough for 2 rooms. Level 2 takes around 20 minutes and level 3 around 30 minutes.
Let's be honest, it's a hoover for in-between jobs, it's absolutely great for when you need to get things done quickly. It's in no way inferior to a Dyson.
I bought it for my mum, she has runners/carpets like this. I went to level 3 and filled half the container with dust in one pass. She took note of it in silence...

I was also super disappointed because it was empty after 10 minutes. 🥲 But it was also on the highest setting, which you might need and want to use from time to time. In the meantime, I just vacuumed on level 1. it probably takes longer 🫠

Half an hour on low setting is reasonable for me. Highest setting only lasts ~10 minutes but this rarely feels necessary.
