We ran the S9 MaxV Ultra daily for six months in a 140 m² home with mixed flooring and two shedding dogs.
Hard-floor pickup was effectively complete in a single pass. On medium-pile carpet it left roughly 6% of embedded debris — good for a robot, short of a cordless.
It avoided every cable and shoe in our obstacle course, and crucially recognised a pet accident and routed around it.
Washing and drying the mop pads removes the job that kills most robot mops. You still empty the dust bag every six to eight weeks and descale monthly in hard-water areas.
Expensive, and the only robot in our test group that ran for six months without requiring a rescue more than twice.

The Home Brief
Several mornings a week. No filler, no fake urgency, unsubscribe in one click.
Two philosophies of robot cleaning, tested over six months in the same home.
Most smart home gadgets get unplugged by month three. These are the categories that stick.
We ran nine robot vacuums through the same messy house. Obstacle avoidance, not suction, separates them.
Interaction rates collapse for most categories by week twelve. Four survive.
