The recently concluded Consumer Electronics Show (CES) 2026 in Las Vegas drew crowds as exhibitors unveiled cutting-edge products showcasing how artificial intelligence (AI) is reshaping everyday life for consumers.

As one of the world's largest and most influential technology events, CES 2026 took place from Jan 6 to 9, attracting more than 4,500 exhibitors from over 155 countries and regions.

At the event, Chinese robot vacuum manufacturer Narwal unveiled its Flow 2 model. Equipped with dual cameras, the device can identify a wide variety of household items and then adjust its route and mode accordingly to ensure effectiveness of its work and prevent disruption.

"[If the] robots detect that there is a pet, they will increase the suction power. If the robots detect that there is a baby sleeping, they will automatically switch to the quiet mode," said Icey Bin, head of Narwal.

One of the most unexpected exhibits at the event was the C-200, the first ultrasonic home chef knife presented by Seattle Ultrasonics. Using ultrasonic sound that vibrates 30,000 times a second to sharpen the blade, it can save half the force for cooks when they cut food ingredients.

"This has no motor. It's battery powered. And the ceramic crystals are actually what charge the blade. So when they send out that volt of power, it goes directly down the metal of the blade," said Caitlin Sanders, special projects manager of Seattle Ultrasonics.

Other novel products include a headphone that can be turned into a portable speaker by a single twist, the Acemate tennis robot that can serve as a mobile opponent, an AI bed with a smart mattress, and lifelike companion robots, such as Sirius, the world's first trainable AI robotic dog created by Hengbot Innovation, a Chinese robotics company.

"AI actually can make Sirius more understand their owners, so just like building a long-term relationship," said Eric Lin, operations director of Hengbot.

Another eye-catching exhibit at the event is Pawport's smart pet door that opens autonomously when a pet wearing a special tag approaches.

First of its kind, the tag is fully encrypted, so the door is completely secure, explained Martin Diamond, founder and CEO of Pawport.

"You set the range from the door that you want it to open. And when your pet goes here, it's just going to open for them," Diamond said.

First held in 1967, the CES is a bellwether for the global consumer electronics industry. It annually presents cutting-edge innovations from tech companies in fields including artificial intelligence (AI), robotics, smart home systems, and autonomous vehicles.
