Viomi is back with a new robot vacuum cleaner / mop. Yes it has improved in a few ways, but it does have one more trick: it can empty its own bin. Is it any good? Let's find out! Find the Viomi S9 on AliExpress here: https://s.click.aliexpress.com/e/_bWG...

The Viomi S9 is the latest model of Viomi's vacuum and mopping robots. It has improved from their latest flagship model the V3 in terms of battery, suction strength and the water tank seems to have gotten improved on this one as well. Other improvements include a better loudspeaker for voice prompts (not all that needed) and more importantly it's a lot more silent when it's vacuuming, comparing it with the V3 as well.
