At CES 2026, ECOVACS unveiled its latest flagship, the DEEBOT X12 series. Moving away from a brush design that had remained largely unchanged for years, the X12 introduces Zero-Tangle 4.0 technology. This conical, single-cantilever system is specifically engineered to solve the "hair wrap" nightmare for pet owners and users with long hair.
Ⅰ. X12 Zero-Tangle 4.0 Core structure and innovations
1. Conical Air-Guide Design
The X12 Zero-Tangle brush features a unique tapered shape—larger at one end and smaller at the other—supported by a single-sided cantilever.
How it works: This structure utilizes aerodynamics and centrifugal force. As the brush rotates, hair naturally slides down the conical slope toward the smaller, unsupported end, where it is effortlessly sucked into the port.
This design was first used in the Narwal J4 released in 2023. Dreame’s recent series of models also use similar structures for their roller brushes.

2. Active Fan-Style Impeller
The Upgrade: ECOVACS has integrated a fan-style impeller at a strategic point on the brush assembly.
The Purpose: It generates active airflow to "push" hair toward the suction inlet. This addition compensates for the increased sliding resistance that occurs when using stiffer, more effective cleaning bristles.
Ⅱ. Advantages
This physical diversion structure is more stable than traditional cutting roller brushes when dealing with long hair and pet hair, and will not cause the problem of blade dulling or clogging.
ECOVACS has opted for stiffer bristles on the X12. This allows for better agitation and deeper cleaning of carpets and stubborn debris, theoretically outperforming soft-bristle anti-tangle designs.
Ⅲ. Disadvantages
The introduction of the active impeller increases the number of precision parts. Additionally, because it is a single-sided cantilever design, the bearing on the fixed end endures significantly higher pressure than traditional dual-supported brushes. In environments, these precision components may experience faster wear and tear.
The combination of stiffer bristles "slapping" the floor and the high-speed active impeller creates a more distinct acoustic profile. Users may notice louder "thumping" sounds on hard surfaces like tile or hardwood compared to quieter, softer brush designs.
As we move through 2026, the DEEBOT X12 is set to become the benchmark for flagship performance. Whether the added complexity of its impeller will withstand the test of time remains to be seen.
