You can never truly empty a box. Suppose you want to empty a box. You remove all its visible contents, pump out any gases, and--applying some science-fiction technology--evacuate any unseeable material such as dark matter. According to quantum mechanics, what's left inside? It sounds like a trick question.

Dirt detect and customizable cleaning solutions. SmartPlan AI still doesn't identify smaller objects. Roborock's Curv robot vacuum is probably the most attractive robot vacuum I've ever tested. The domed white docking station is attractive, convenient, and compact. It doesn't hurt that Roborock's navigation and cleaning systems are consistently the best among the robot vacuums I've tested.

ESTLast modified on Fri 9 Jan 2026 10.00 EST This year will be filled with robots that can fold your laundry, pick up objects and climb stairs, fridges that you can command to open by voice, laptops with screens that can follow you around the room on motorised hinges and the reimagining of the BlackBerry phone. Those are the predictions from the annual CES tech show in Las Vegas that took place this week. The sprawling event aims to showcase cutting-edge technology developed by startups and big brands. Many of these fancy developments will be available to actually buy, moving from outlandish concepts to production devices, although some are still limited to costly prototypes.

Dreame's latest robot vacuum concept has slightly terrifying legs that can climb full-size stairs The Cyber X can maneuver steps up to 25 cm tall. The Dreame Cyber X is a prototype for now. Robot vacuum companies are once again trying to outdo each other at CES 2026. This year, Chinese appliance maker Dreame is showing off a prototype of a device that can climb up and down an entire flight of stairs. The concept, called the Cyber X, was previewed last year at IFA in Berlin.

Dreame's robot vacuum with an arm is back at CES 2026 and it can do more than pick up shoes The Cyber 10 Ultra has its own attachments for reaching hard-to-get places. Dreame's Cyber10 Ultra has an arm that can grab objects and clean hard to reach areas. Last year at CES, Dreame showed off a robot vacuum prototype with a mechanical arm . But while we were able to see the arm extend and retract, we didn't see the device, which was described as a prototype at the time, actually grab anything, which was a bit disappointing. This year, though, the company has made its arm-enabled vacuum a reality with the Cyber 10 Ultra.

Narwal's first mattress vacuum heats, taps, UV-blasts and sucks up all the ick living in your bed At CES, the robotic cleaning brand also showed off its new flagship mop vac than can track down your pets. The Narwal U50 series mattress vac held aloft on the CES Unveiled floor. Narwal brought new cleaning robots with it to CES this year, including the Narwal Flow 2, it's latest flagship robo mop-vac, and the Narwal U50, an automatic mattress vac designed for "deep mite removal." While I'd hoped the latter vac was an automatic crawler that could navigate your mattress top, the U50 is a handheld device. Still, no one likes to think about what filters down into their mattress as they sleep -- and there are lots of opinions on how and why to remove those dead skin cells, dust, oils and the mites that arrive to dine on those things.
