Drying function it dries the roller brushes with hot air to prevent bad odors and mildew buildup
Edge-cleaning effectiveness as with the h12 pro it does have dual Edge cleaning which is really nice
Price the h12 pro is way cheaper I think it's about $450 and it's discounted often to about $380
Self-cleaning cycle effectiveness put the vacuum back on its base which charges the vacuum cleaner but also it runs a cleaning cycle so it cleans the roller brushes and it flushes all the internal system and ducts and empties everything into the dirty water tank
Wet-dry 2-in-1 design it simply is a vacuum that vacuums your floor but at the same time also cleans them with water and sucks away any wet messes as well
Just Okay
Battery runtime / Charging time battery life on the h12 pro is 35 minutes
Needs Improvement
Automatic suction adjustment (dirt sensing) the sensor on the auto mode they detect debris or wet messes but what if you have a stain or a dried out mess the auto mode is not going to detect it
Filter in dirty water tank there was no filter in the dirty water tank to collect solid debris
Power setting versatility it had three cleaning modes instead of four on the h13 pro
Ultra mode (electrolysis) the ultra deep mode which does an electrolysis of water does give you a better cleaning performance in theoryI don't really think there's much utility in the electrolisis or in the ultra mode
