How long Samsung’s Bespoke AI Jet Ultra vacuum battery really lasts

One of the biggest concerns for classic vacuum cleaner users thinking about going wireless is battery life. And for good reason. Stick vacuums usually can’t be plugged in mid-clean, so once the battery’s dead, you're forced to take a break. So how does battery life look on Samsung’s best wireless stick vacuum, the Bespoke AI Jet Ultra?

As always, results vary. Accessories, floor types, and suction levels all play a role. That said, you can generally expect more than one hour of use from a full Bespoke AI Jet Ultra battery under the most optimal conditions. Here’s what our real-world testing shows.

Brush choice also matters. Motorized brushes tend to drain the battery faster, but not always, as you’re about to see.

Here’s what the Bespoke AI Jet Ultra delivers on a full charge using the LED-enabled Active Dual Brush on smooth floors (wood or tiles):

Switch to a simple, non-motorized combination tool, and runtimes change noticeably:

As you can see, the non-motorized brush significantly boosts runtime at lower suction levels.

However, there’s a trade-off. Without a motorized brush drawing power, the vacuum can push the motor harder at higher settings. That means stronger suction, but dramatically reduced autonomy.

First, in some markets, the Bespoke AI Jet Ultra ships with a standard 100-minute battery. In others, Samsung offers the 100-minute unit plus an additional 60-minute battery. The accessory set is not the same everywhere.

Second, your results may differ. Floor types matter, and AI mode adds another variable by dynamically adjusting suction power and brush speed on the fly.
