3i S10 Ultra Robot Vacuum and Mop: The Future of Home Cleaning is Here

The morning sun streams into the living room, illuminating a scene of impossible tranquility. A golden retriever dozes peacefully, its tail occasionally thumping against a floor so clean it mirrors the sky outside. A toddler’s building blocks are neatly corralled in a corner. There are no tell-tale signs of the previous evening’s chaos, no frantic morning clean-up. The air is fresh, the surfaces gleam. It’s a perfect domestic picture, with one glaring omission: the effort. This raises a question that hangs in the quiet air: who, or what, is the invisible janitor of this home?

The tranquility shatters with the beautiful chaos of family life. Breakfast becomes a small disaster zone of spilled cereal, milk, and juice. The dog, in a fit of morning joy, leaves a fine, golden trail of fur. This is the daily, Sisyphean reality of a busy home—a constant battle against the second law of thermodynamics, which dictates that order will always decay into chaos. But today, the response isn’t a weary sigh and a reach for the paper towels. It’s a quiet command, and from its unassuming dock, the janitor awakens.

Seeing with Light, Thinking in Code

Before it moves an inch, it first sees. Not with eyes, but with invisible pulses of light. This is the domain of LiDAR (Light Detection and Ranging), a remarkable technology with a lineage stretching back to atmospheric science and now famously responsible for guiding autonomous cars through complex city streets. The 3i S10 Ultra employs a particularly advanced form known as dToF (direct Time-of-Flight). The principle is both simple and profound: the robot emits a harmless laser beam and measures the exact time, down to the nanosecond, that it takes for the light to hit an object and bounce back.

By repeating this process millions of times per second in a 360-degree arc, it doesn’t just create a floor plan. It builds a high-fidelity, three-dimensional digital twin of its environment. The new armchair, the dog’s favorite chew toy, the forgotten pair of slippers—they are all rendered in its memory with startling precision. This digital consciousness, a map of light and shadow, allows it to plan its campaign against the morning’s mess not with random bumps and turns, but with the calculated efficiency of a military strategist. As one user noted of their first experience, the initial mapping run was “very fast and looked accurate,” a testament to the power of seeing with light.

The Alchemist in the Corner

As the robot glides silently towards a sticky patch of juice, its mopping pad is already perfectly damp, ready for action. But where does the endless supply of clean water come from? The secret lies within its base station, a unit that functions as a veritable alchemist’s workshop. This is where the groundbreaking WaterRecycle System performs its daily magic, a process rooted in fundamental physics.

First, it tackles the dirty water from the previous cleaning run through distillation. This is one of humanity’s oldest purification methods. The collected wastewater is gently heated, and as the water molecules transition into steam, they leave the heavier dirt, grime, and mineral particles behind. The purified water vapor is then cooled and condensed back into pristine, liquid H₂O.

Simultaneously, the station performs a second, equally clever trick: dehumidification. It draws in ambient air from the room and, much like a household dehumidifier, cools it past its dew point. This forces the invisible water vapor in the air to condense into liquid. The amount of water it can harvest is dictated by the relative humidity of the room, yet as one user, Brian, discovered with pleasant surprise, the system effectively refilled its tank even in the dry air of a home during winter. This self-sufficient loop, turning household waste and thin air into a powerful cleaning agent, is what allows users like Maggie, who contends with two dogs, to “return to spotless floors” without the daily chore of refilling and draining.

Conquering Geometry and Defeating Tangles

The robot now faces two of its ancestors’ greatest nemeses: the stubborn grime that collects in corners and the relentless entanglement of hair around its brushes. These are not trivial problems; they are challenges of geometry and physics. The S10 Ultra’s answer is a display of elegant mechanical engineering.

To solve the corner conundrum—the inherent difficulty of a circular object cleaning a 90-degree angle—it deploys its UltraReach Extendable Roller Mop. As its sensors detect a wall or the leg of a table, a small mechanical arm extends the spinning mop head outwards, bridging the gap. It’s a simple, brilliant motion, like a dragonfly dipping into water, that allows it to achieve millimeter-level contact with edges that other robots miss.

At the same time, it wages war on tangles with its Dual Anti-Tangle Design. This isn’t just about brute force suction; it’s a strategic, two-part ballet. While cleaning, a built-in comb acts as a gatekeeper, preventing long strands of human and pet hair from wrapping tightly around the main brush. The real masterstroke occurs back at the base station. The robot reverses the direction of the brush’s spin, allowing a second, more aggressive detangling comb to actively strip away any captured hair, which is then immediately sucked away into the dustbin. For homes with furry family members, this feature transforms a frequent, frustrating maintenance task into an automated, forgotten process.

The Pit Stop and the Promise of Tomorrow

The mission is complete. The spills are gone, the fur has vanished. The floor is spotless. The robot now performs its final, crucial maneuver: it returns to its “mothership.” This docking procedure is far more than a simple recharge; it’s a fully automated Formula 1 pit stop, designed for peak performance and hygiene.

A powerful vacuum inside the base station roars to life, its force measured in thousands of Pascals (Pa)—the SI unit of pressure, named after the physicist Blaise Pascal. This suction clears the robot’s onboard dustbin in seconds, depositing the day’s debris into a large, sealed 2.5L bag that can hold up to two months of dirt. Next, the soiled roller mop is thoroughly washed with the purified water it helped create, then gently dried with a stream of warm air to prevent the growth of mildew and bacteria. Finally, the robot’s water tank is topped off. It is reborn, fully serviced and ready for the next call to duty.

As evening falls, a quiet settles over the house. The family relaxes in their pristine living room, the memory of the morning’s chaos already faded. In the corner, the invisible janitor sits silently in its dock. Its presence is no longer defined by its motion or its sound, but by its absence of need. The ultimate luxury it provides isn’t just a clean floor, but the gift of reclaimed time and the quiet peace of mind that comes from having one less chore to worry about.

This intricate symphony of light, water, and algorithms is a marvel of modern engineering. Yet, the path to true, flawless automation is a journey, not a destination. As the experiences of some users with technical glitches or performance inconsistencies show, such complex systems can sometimes miss a note. These moments are stark reminders that we are witnessing a technology in its ascendancy, not its final, perfected form. Still, the quiet, humming presence of this machine is a powerful testament to human ingenuity and our relentless quest for a life less burdened. It is the sound of the future, happening right now, in the corner of the living room.
