From manual tank fills to air-powered distillation, the S10 robot vacuum spans the full spectrum of water management innovation—and your choice determines how hands-off cleaning actually gets.
The Budget Reality Check
The S10 keeps things simple with proven tech and manual maintenance.
The 3i Robot Vacuum S10 doesn’t pretend to be revolutionary. With 4000Pa suction and reliable LiDAR navigation, it handles the fundamentals without drama. You’ll get 130 minutes of runtime covering up to 75 square meters, zigzagging under furniture with methodical precision.
But here’s where the “smart” label hits reality: you’re still filling and emptying water tanks manually. The S10+ variant adds dual rotating mops for better wet cleaning, yet you’re locked into the same maintenance routine your parents dealt with—except now a robot does the actual mopping.
This appeals to households wanting proven automation without bleeding-edge complexity. Think of it as the Honda Civic of robot vacuums: dependable, affordable, and totally fine with being predictable.
The Air-to-Water Breakthrough
3i’s S10 Ultra generates its own distilled water from ambient humidity, redefining autonomous cleaning.
The 3i S10 Ultra throws conventional water management out entirely. Its proprietary WaterRecycle™ System extracts moisture from ambient air, distills it at 90°C, then purifies it through silver ion treatment. No plumbing hookups, no manual refills—just atmospheric humidity transformed into cleaning solution.
This engineering marvel delivers 13,000Pa suction while extending its UltraReach™ mop near walls with millimeter precision. The 12-in-1 dock handles everything from dust collection to mop drying automatically for 60+ days.
Reality check: the system needs humidity above 30% and temperatures over 17°C to function optimally. Premium pricing reflects the category’s only air-to-water conversion technology.
Editor’s note (4/27/2026): We incorrectly referred to the 3i S10 as the Xiaomi S10 in a few instances and corrected this.
