Top 10 Worst CES Products of the 21st Century

Why is CES so obsessed with strapping things to our heads?

It’s a wrap on CES for another year, and together we’ve seen our share of both weird and wonderful devices in 2023, but… mostly weird.

Flying cars and obscure robots are so old hat now, and so I wondered if CES could do anything less practical and even more completely bonkers. Turns out it can! Over the past 20-plus years, I’ve seen gadgets so stupefying that sometimes they exist purely because journalists like me will write about them. But it’s time to call out the really awful ones, the worst of the worst. Vacuum shoes, toilet paper robots, MP3 weapon holsters, it’s your time to shine!

The most interesting part about this rogues gallery is that some of these products — the PePe pet dryer, the HapiFork and the HushMe, to name a few — are still being sold today. That’s right: You blew it up, you maniacs!

Dyson Zone Air-Purifying Headphones

Not technically a CES product as this was announced during 2022, but Dyson was displaying the Zone Headphones on its stand at CES 2023. Though the Zone looks like it should be a COVID mask, that’s unfortunately not what it does. According to the Dyson site, development on the Zone began way back in 2016 as a personal air filter — for pollution, mainly — and as such, it was never designed to protect against COVID. Furthermore, one critic has claimed the gadget’s force-driven fans could even help maximize your chances of catching coronavirus.

Charmin Rollbot

Computer peripherals manufacturer Razer is the king of creating «look at me» products specifically for CES, but toilet tissue brand Charmin became notorious for this 2020 entry. That’s right, in the year that saw the mass panic buying of toilet paper came a robot that could bring you even more! Coincidence? Yes… probably. The RollBot was never going to be a real product, but we loved/loathed it anyway.

Kolibree Smart Toothbrush

Remember when we had to wash our hands for 20 seconds by singing songs to ourselves? The same methodology also applies to brushing your teeth, but why should you use your own brain and lips like a sucker? There have been many smart toothbrushes over the years, but today I’m picking on the Kolibree. Everything was just fine until the arrival of «the world’s first connected electric toothbrush.» Happy birthday to you, happy birthday to you…

Taser MP3 Holster

Back in the 2000s, the iPod became such a cultural phenomenon that every company rushed to create an MP3 player of its own. This culminated in what is one of the dumbest CES products in recent memory: the Tazer MP3 holster. Imagine trying to not only charge your holster but also connect it via USB to your computer to fill it up with 1GB of tunes.

Pepe Pet Dryer

Want to find a new way to make your small dog or cat hate you forever? Lock them in a cube prison for 25 minutes(!) and subject them to gusts of hot air. This combination torture device/dryer would have set you back $660, or you could just throw a towel over your wet dog like a normal human.

HapiFork

Throughout history, there have been so many gadgets designed to limit normal human behavior, but this one takes the (pan)cake. The HapiFork is yet another vibrating gadget that tells you to eat your meals slower (over 20 minutes), with the idea being that you are less likely to overeat. Personally, I wolf my own meals down like I’m in prison, so do your worst, HapiFork. I’ll eat with my hands if I have to! You’re not the boss of me!

Hushme

The Hushme is literally a «dumb» product — it’s designed to make its user mute to other people in the immediate vicinity. It was pitched as being useful in workplaces, but… if a co-worker gave me one of these, they’d better be wearing vacuum shoes, in order to clean up the gleefully stomped-on bits.

Belty

The original Belty was a prototype smart belt with a motor in it that adjusted itself to whether you just ate or were sitting down. Impractical as hell, but kind of cool? While there is a newer model, also called Belty, this one is even weirder — there’s no auto-sizing, but it does have a power bank charger in the buckle. OK, two things. Not only do I not want a potentially volatile compound near my nethers, I don’t want to connect a series of devices there either.

Xybernaut Poma

First shown off at CES 1998, the Hitachi-Xybernaut wearable computer was a terrible idea long before Google Glass was even a gleam in Babak Parviz’s eye. The Windows CE-based Xybernaut Poma offered a 128-MHz RISC processor and 32 MB of RAM, plus it strapped to your arm and your face and your belt!

Denso Vacuum Shoes

Shoes. You wear ’em. They wear out, you buy more. But that’s not exciting now, is it? They need things in them — phones, rockets, rollers, and… vaccuums? There are so many puns I could make about even just the name of the Denso Vacuum Shoes, but the fact that they existed at all was the biggest joke of all.

Yes, This Swimming RoboTurtle Is Adorable. It Also Has an Important Environmental Mission

Beatbot is best known for making pool-cleaning robots, but it was its swimming robot turtle that won our hearts at CES 2026.

Few things in life have made me feel more privileged and awestruck than the opportunity to swim with sea turtles in their natural environment. The way in which these gentle creatures navigate through their underwater world with their deliberate and careful fin strokes is utterly mesmerizing to watch.

It’s a distinctive style of movement — so much so that when I saw Beatbot’s RoboTurtle swim across a water tank on the show floor at CES 2026, I knew that this wasn’t simply just a pool cleaner robot with turtle features tacked on. This was a studied example of biomimicry in action.

The reason for this is that the company’s engineers went on a two-month expedition to study sea turtles in their natural environment, Beatbot’s Eduardo Campo told me as we watched Turtini (the team’s affectionate nickname for RoboTurtle) splash around in its pool. «We did a lot of motion capture, like the things they use in movies, because we need to develop those joints that it has,» he said.

This isn’t RoboTurtle’s first time at CES — it also appeared in 2025 as a static concept. This is the year, however, it’s found its fins, so to speak. Not only can it swim, but it can also respond to hand gestures: I throw it an OK gesture, and it dances in response. But as cute and limber as it is, RoboTurtle is a robot with an important mission.

RoboTurtle is an environmental research tool, built with input from researchers and NGOs, which can go where humans or other machines cannot for fear of disturbing complex and delicate underwater ecosystems, particularly coral reefs. It can move silently and naturally in a way that won’t scare wildlife, monitoring water quality and fish numbers with its built-in camera.

«One of the groups that we’re working with, they want to study the coral reefs in near Indonesia,» said Campo. «There was a very big incident over there with a boat that came up onto a coral reef and it disrupted the environment, [so] they want the least intrusive robot possible.»

The group wants to deploy RoboTurtle for certain periods every year to monitor the recovery of the coral and monitor the fish population, he added. Beatbot is currently training the built-in AI to give RoboTurtle monitoring and recognition skills.

At CES, I watched RoboTurtle paddle about only on the surface of the pool, but it can also dive down up to five meters. However, it needs to resurface to send data and its GPS signal back to base, much like a real turtle that needs to come to the surface to breathe. This also gives it a chance to recharge via the solar panel on its back.

Even though I was impressed with RoboTurtle’s swimming ability, Campo estimates that the Beatbot team is still a year and a half away from perfecting its technique, with the robot ready for full deployment in between three to five years.

CES 2026 is a show where tech with a real purpose feels scarce, so it sure is refreshing to see a company use its expertise to build something designed with a sustainable future in mind. It might be a while until we see RoboTurtle take to the seas, but I’m glad that I got to witness it at this stage of its journey.

These Tiny Robots Are Smaller Than Grains of Salt and Can Think, Move and Swim

Despite their size, the robots can navigate liquids, respond to their environment and operate without external control.

Robots smaller than a grain of salt? It sounds like science fiction, but researchers have developed autonomous microrobots that can move through liquids, sense their environment and operate independently using only light as a power source.

The microrobots, developed by researchers at the University of Pennsylvania and the University of Michigan, measure roughly 200 by 300 by 50 micrometers. Yet they can detect temperature changes, follow programmed paths and function independently for months at a time.

Their work was reported this week in two scientific journals, Science Robotics and Proceedings of the National Academy of Sciences.

«We’ve made autonomous robots 10,000 times smaller,» senior author Marc Miskin, assistant professor in electrical and systems engineering at Penn Engineering, said in a statement. «That opens up an entirely new scale for programmable robots.»

Powered entirely by light, the robots don’t move using mechanical limbs. Instead, they generate tiny electrical fields that push ions (electrically charged particles) in fluid to create motion, an approach better suited to the unique physics of the microscopic world, where traditional motors don’t work.

Unlike earlier microrobots, these devices combine sensing, computing, decision-making and movement in a single, self-contained system at an extremely small scale.

Previous efforts in microrobotics have often relied on external controls, such as magnetic fields or physical tethers, to guide movement. These new microrobots, however, incorporate their own miniature solar cell-powered processors, allowing them to respond to their environment, communicate through patterned movements visible under a microscope and carry out tasks without outside direction.

Potential applications include monitoring biological processes at the cellular level, supporting medical diagnostics or helping assemble tiny devices. Because each robot can be mass-produced at very low cost, the technology opens new avenues for research and engineering at scales that were previously unreachable.
