Among its many descriptors, the most important one is undoubtedly this — Samsung’s most powerful cordless stick vacuum cleaner.^[2] The Bespoke AI Jet Ultra, capable of delivering up to 400W of suction power,^[3] is revolutionising the cleaning experience for consumers in their daily lives.

What really makes it all happen is a process you can’t see: Air moving through the vacuum’s complex internal system, carrying everything from fine dust to stubborn debris. This invisible air path determines how strong, stable, and effective a vacuum’s suction truly is.

Samsung spent six years refining that journey. Every twist and turn, from intake to motor, was reengineered to allow air to move without interruption.

The multi-cyclone system: Your personal spin expert

When air enters the vacuum, it carries everything from pet hair to fine dust^[4] particles. It travels through a long internal air path and encounters the multi-cyclone system where it spins at high speed. The centrifugal force flings dust outward, separating particles so clean air can move forward – efficient, but intense.

However, the spinning also creates resistance that can weaken suction. To address this, Samsung introduced a multi-cyclone structure with 12 cyclones and 33 air inlets. With more entry points and evenly distributed airflow, resistance is reduced, allowing efficient dust separation while maintaining strong, stable suction.

The motor: Through the eye of the storm

After the cyclone system, the air reaches the motor, spinning at up to 148,000 revolutions per minute. Inside, the impeller, — shaped like jet engine blades—spins air outward to create a vacuum. If air flows the wrong way back in, it disrupts suction. To prevent this, Samsung upgraded the diffuser from single-row to a two-row structure,^[5] giving air more exit routes to maintain vacuum pressure and suction consistency. This helps maintain vacuum pressure and consistent suction by allowing air to escape more smoothly.

The Real-Life Impact of 400W Suction Power

What practical difference does the 400W suction power actually make in real life? Recently, Samsung released a video showcasing experiments conducted in various environments to demonstrate just that.

In one test, a ball is placed on one end of a tube. When the vacuum runs on Max, the ball slowly rolls forward but eventually stops midway. However, in Jet mode, it zips straight to the inlet and sticks.

In another,  a tube pulls water from a water tank. Max mode lifts the water halfway, while Jet mode fills at such a rapid speed that it overflows the tank. This power is just one part of what makes the overall product stand out.

Driven by the details

From the shape of a cyclone to the structure of a diffuser blade, every element of the Bespoke AI Jet Ultra was optimised with one goal: let air do its job without obstruction. With this device, Samsung didn’t just create a vacuum. It added details to the path air takes, and in doing so, pushed suction performance to a whole new level.
