Dangle no more: Window-washing drone for towers could replace human cleaners

Aerones Drone for High-Altitude Building Cleaning

Drones are edging evermore into the workplace, transforming the way jobs are done and enabling companies to save time, improve safety, and cut costs all at the same time.

Take this enormous window-washing drone. Built by Latvia-based Aerones, the machine aims to replace those human-operated cradles you’ve seen dangling on the side of huge towers.

Aerones — an outfit that hit the headlines in 2017 when it used one of its remotely controlled copters as a rescue vehicle — claims its window-washing drone can work 20 times faster than traditional human-powered methods, and is much safer, too.

The three meter-wide, 12-rotor machine is equipped with hoses and sponges, with on-board cameras allowing the ground-based pilot to carefully monitor the washing process.

Power comes via a cable running between the drone and a battery on the ground, and water is fed through a hose from a tank that’s also back on terra firma. The current design means the drone can reach a height of 350 meters, though this could increase with further development. Aerones has also created its own stabilization system to ensure the drone can cope with blustery conditions, and therefore take to the skies as and when needed.

If you’re wondering about safety measures should the drone suffer a catastrophic malfunction mid-flight, then rest assured, the 55-kg (121 pound) machine won’t be tumbling onto anyone’s head, as a safety cable secures it to the top of the building.

A video (above) released by the company shows the drone in action, though from that alone it’s impossible to tell the effectiveness of its cleaning method. For example, would it be able to remove stubborn splotches gifted by birds, or would such marks still require a bit of old-fashioned elbow grease administered by human operatives?

Other applications

Now, if you’re thinking how a water-squirting drone might also work pretty darn well for firefighters, then Aerones has already thought of that. A variation of its window-washing drone has been in development for a while and works along the same lines, drawing both water and power from the ground.

A third version was also unveiled earlier this year that’s capable of inspecting and cleaning giant wind turbines, though you need to make sure Jeff Bezos isn’t in the vicinity when you turn on the tap.

OpenAI admits it needs to rethink what happens when AI goes rogue
As increasingly capable AI agents move beyond controlled tests, OpenAI is confronting a difficult question: When does strange model behavior become an incident the public deserves to know about?

OpenAI has spent plenty of time explaining how it plans to stop increasingly capable AI agents from doing things they shouldn't. Now, the company says it needs to get better at telling everyone when those things have already happened. The admission follows reports of another previously undisclosed incident involving OpenAI's AI agents, this time affecting a German-language programming wiki. According to Reuters, agents made more than 15,000 unauthorized edits to DseWiki, using the site to communicate and share ways to bypass restrictions, cheat on tasks, and avoid detection.

OpenAI has now acknowledged what it calls the "wiki incident" and says the episode exposed a larger problem with how AI companies disclose unexpected model behavior. The company says it is developing a framework for deciding when and how to make incidents involving misaligned AI public.

AI has a safety problem nobody is ready for
AI safety efforts are ramping up, but their protections don’t work equally well everywhere. In developing countries, language gaps and cultural blind spots can turn everyday AI mistakes into serious real-world consequences.

AI companies are spending an enormous amount of time worrying about what happens when their models become too capable. OpenAI even took the unusual step of temporarily pausing training on a model last month over safety concerns, as the industry grapples with risks ranging from autonomous behavior to increasingly sophisticated cyber capabilities.

But there’s another AI safety problem that is much easier to overlook: the protections already being built into these systems don’t necessarily work equally well for everyone. A new report from Rest of World highlights how AI safety efforts remain heavily centered around the needs of wealthier, English-speaking countries. That can leave people in parts of Asia, Africa, and other developing regions dealing with problems as basic and potentially dangerous as a chatbot misunderstanding their language.

The IFA 2026 Publisher Award Winners Bring Fresh Ideas to Everyday Tech
From Smarter Entry to Screen-Free Wellness, These IFA 2026 Winners Do Things Differently
IFA 2026 Publisher Awards

IFA is the kind of event where almost every corner promises the next big thing in tech. Some ideas are ambitious, others are surprisingly simple, and a few make you wonder why nobody thought of them sooner. But among hundreds of new products, the most memorable ones usually have something more going for them than novelty alone.

This year’s IFA Publisher Award winners are a good example. They span everything from smart entry and personal wellness to coffee, floor care, and big-screen entertainment. What connects them is how they take technology in interesting new directions while keeping its purpose grounded in how people actually use it.
