Everybot's ThreeSpin Slim drops the wheels — three mop pads move and scrub at once

Robot vacuums had settled on a formula — wheels to move, a pad or brush to clean — that left the machine tall, and wheeled mops pressed lightly on the floor while their wheels left marks. Everybot, a Korean AI-service-robot maker, asked what a mop robot would look like if the cleaning surface itself did the driving.

Let the mop be the motor: three rotating pads replace wheels, so the robot presses, drives and scrubs in one motion — and the whole body can shrink.

The ThreeSpin Slim (TS450) applies Everybot's patented ROBO-SPIN structure: three rotating mop pads take the place of wheels, turning to move the robot while the full body weight presses down on the cloths for strong, close contact cleaning. Removing wheels let the body drop to an 83-millimetre profile, among the slimmest dedicated mop robots, and the mechanism itself became the visual design rather than something to hide.

In 2026 the TS450 won the iF Design Award Gold — its highest distinction — and then the Red Dot Design Award in Product Design, a double win across two of the world's three major design prizes that the company described as rare in the robot-vacuum market. Design press singled out how the ROBO-SPIN structure was translated into the product's form rather than hidden inside it.

A wheeled robot mop carries two systems that never meet: wheels that move it and cloths that clean it. Everybot's ThreeSpin Slim (TS450) collapses the pair into one — three rotating mop pads replace the wheels, turning and driving the robot while the machine's full weight presses the cloths into the floor.

The structural change produced a visible design win. With no wheel assembly to house, the TS450 slimmed to an 83-millimetre body, and the ROBO-SPIN mechanism became the product's signature rather than a component to be concealed. The pads scrub as they steer, so the robot's everyday motion is also its cleaning motion.

The idea earned the machine a rare double crown: iF Design Award Gold in March 2026 and a Red Dot Product Design award that April, placing the Korean maker among the few robot-vacuum brands to take top honours at two of the world's three major design competitions in the same year.

Replacing wheels with mop pads removed a whole subsystem, which is why the body could get dramatically thinner.

Body weight pressing on the cloths made contact cleaning stronger than wheeled designs that glide lightly.

Exposing the ROBO-SPIN structure as the design gave the product a mechanic other brands could not easily imitate.

Winning iF Gold and Red Dot back to back proved the technical idea read as premium design, not engineering.

When a mechanism can do two jobs, let it: removing wheels to make cleaning pads drive the robot turned a functional trade-off into a thinner product with a story no rival could copy.

Everybot's design R&D centre, recognised in 2024 as an official corporate industrial-design laboratory by South Korea's science ministry and KOITA, took credit for the double win, and the company said it would use the awards to push its robot cleaners from household appliances toward premium lifestyle products.
