Window-washing robots are working on Manhattan skyscrapers

Skyline Robotics is disrupting the century-old practice of window washing with new technology that the startup hopes will redefine a risky industry.

Its window-washing robot, Ozmo, is now operational in Tel Aviv and New York, and has worked on major Manhattan buildings like 10 Hudson Yards, 383 Madison, 825 3rd Avenue, and 7 World Trade Center in partnership with the city’s largest commercial window cleaner Platinum and real estate giant The Durst Organization.

The machine is suspended from the side of a high-rise. A robotic arm with a brush attached to the end cleans the window following instructions from a LiDAR camera, which uses laser technology to map 3D environments. The camera maps the building’s exterior and identifies the parameters of the windows.

“What the LiDAR is actually doing as the basket is descending is sort of painting itself a picture of the facade that it’s facing,” Blum said.

Although the Ozmo is controlled by a human operator at the top of the building, chief operating officer and founder Ross Blum said that the robot could be operated fully remotely.

“That person, other than regulation, doesn’t actually have to be there for our sake,” Blum said. “We could, in theory, remote-control Ozmo from different parts of the world.”

Reverse osmosis removes contaminants from the water, hence the name Ozmo. According to Blum, this makes the cleaning process more efficient.

“We don’t need a separate squeegee and a separate brush to get a perfectly clean window,” he said. “It’s one motion,” he said.

The current cost of the Ozmo is approximately $500,000, which has a three-to-five-year payback for building owners, according to Skyline Robotics board member and Platinum CEO James Halpin.

A changing workforce

The machine is part of a new wave of technology that can replicate human work. In recent months, artificial-intelligence innovations like ChatGPT have dominated headlines, prompting questions about employment vulnerabilities in customer service, writing and computer programming gigs.

A 2020 report by the World Economic Forum states that 85 million jobs will be displaced by 2025 due to the “robot revolution,” but that 97 million jobs requiring “reskilling and retraining” will be generated.

Jobs in maintenance and construction, like window washing, were ranked as having a “medium” share of tasks (30% to 70%) susceptible to automation, according to a 2016 study by the Brookings Institution.

Platinum’s Halpin said his company was interested in supporting the Ozmo because of a worker shortage in the field of high-rise window washing.

“Currently, we are experiencing a labor shortage in all real blue-collar fields in New York City,” Halpin said. “We could hire another 20% just to keep up with the current work that we have at this point.”

Both Halpin and Blum said their goal eventually is not to replace human workers but to “retrain and reassign” window washers to operate the technology.

But logistically, the Ozmo cuts down on the amount of people needed to clean a building from a team of three to four human window washers to one operator.

The Ozmo has some window washers, like Jose Nieves, a 23-year veteran of the industry and window washer at Rockefeller center, concerned about their livelihoods. He believes the dangers of window washing are overblown and that human labor should be preserved.

“Of course, there are dangers with our profession, but we are skilled, trained workers who take those risks very seriously much like many dangerous jobs that exist in this country,” Nieves said. “Are there no possible dangers associated with a robot operating heavy equipment hundreds of feet above people’s heads?”

Nieves is represented by the SEIU 32BJ, the property service union for many of the workers on the East Coast. According to the organization, there are 500 to 550 unionized window washers in New York City who earn $31.69/hour during the peak summer season.

“As a society we should not be cutting costs on the backs of workers,” Nieves said. “I would say we have been doing a great job without these robots. Don’t fix it unless it’s broken.”

Robot-human collaboration

A growing legion of futurists, like senior research associate at Harvard’s Labor and Worklife Program Aleksandra Przegalińska, study how humans and robots can collaborate, and specifically how machines can take on tedious or dangerous tasks for humans.

Because the Ozmo technology is so new, she said it’s hard to fully evaluate, but the opportunity to shift human labor away from a dangerous field is appealing.

She cites one example when machines, like the Moxi, were deployed to deliver medication to infected patients during the height of the coronavirus pandemic.

“Certainly, in those areas where your health, your existence is at risk as a human, using a machine, a robot is something worth considering,” Przegalińska said.

Skyline has been working on the robot since 2017 and the company raised $6.5 million in their pre-Series A funding, in addition to a grant from the Israeli government.

Amazon faces FAA probe after delivery drone snaps internet cable in Texas

Amazon is facing a federal probe after one of its delivery drones downed an internet cable in central Texas last week.

The probe comes as Amazon vies to expand drone deliveries to more pockets of the U.S., more than a decade after it first conceived the aerial distribution program, and faces stiffer competition from Walmart, which has also begun drone deliveries.

The incident occurred on Nov. 18 around 12:45 p.m. Central in Waco, Texas. After dropping off a package, one of Amazon’s MK30 drones was ascending out of a customer’s yard when one of its six propellers got tangled in a nearby internet cable, according to a video of the incident viewed and verified by CNBC.

The video shows the Amazon drone shearing the wire line. The drone’s motor then appeared to shut off and the aircraft landed itself, with its propellers windmilling slightly on the way down, the video shows. The drone appeared to remain in tact beyond some damage to one of its propellers.

The Federal Aviation Administration is investigating the incident, a spokesperson confirmed. The National Transportation Safety Board said the agency is aware of the incident but has not opened a probe into the matter.

Amazon confirmed the incident to CNBC, saying that after clipping the internet cable, the drone performed a “safe contingent landing,” referring to the process that allows its drones to land safely in unexpected conditions.

“There were no injuries or widespread internet service outages. We’ve paid for the cable line’s repair for the customer and have apologized for the inconvenience this caused them,” an Amazon spokesperson told CNBC, noting that the drone had completed its package delivery.

Amazon delivery drone snaps internet cable in Texas

The incident comes after federal investigators last month opened a separate probe into a crash involving two of Amazon’s Prime Air drones in Arizona. The two aircrafts collided with a construction crane in Tolleson, a city west of Phoenix, prompting Amazon to temporarily halt drone deliveries in the area.

For over a decade, Amazon has been working to realize founder Jeff Bezos’ vision of drones whizzing toothpaste, books and other goods to customers’ doorsteps in 30 minutes or less. The company began drone deliveries in 2022 in College Station, Texas, and Lockeford, California.

But progress has been slowed by a mix of regulatory hurdles, missed deadlines and layoffs in 2023 that coincided with broader cost-cutting efforts by Amazon CEO Andy Jassy.

The company has previously said its goal is to deliver 500 million packages by drone per year by the end of the decade.

The hexacopter-shaped MK30, the latest generation of Amazon’s Prime Air drone, is meant to be quieter, smaller and lighter than previous versions.

Amazon says the drones are equipped with a sense-and-avoid system that enables them to “detect and stay away from obstacles in the air and on the ground.” The company recommends that customers maintain “about 10 feet of open space” on their property so drones can complete deliveries

The company began drone deliveries in Waco earlier this month for customers within a certain radius of its same-day delivery site who order eligible items weighing 5 pounds or less. The drone deliveries are supposed to drop packages off in under an hour.

Amazon has brought other locations online in recent months, including Kansas City, Missouri, Pontiac, Michigan, San Antonio, Texas, and Ruskin, Florida. Amazon has also announced plans to expand drone deliveries to Richardson, Texas.

Walmart began offering drone deliveries in 2021, and currently partners with Alphabet’s Wing and venture-backed startup Zipline to make drone deliveries in a number of states, including in Texas.

CNBC Daily Open: Nvidia's crown looks increasingly uneasy on its head

Uneasy lies the head that wears the crown.

Shares of artificial intelligence czar Nvidia fell 2.6% on Tuesday as signs of unrest continued rippling through its kingdom.

Over the month, Nvidia has been contending with concerns over lofty valuations and an argument from the “The Big Short” investor Michael Burry that companies may be overestimating the lifespan of Nvidia’s chips. That accounting choice inflates profits, he alleged.

The pressure intensified last week in the form of a potential challenger to the crown. Google on Nov. 18 announced the release of its new AI model Gemini 3 — so far so good, given that Nvidia isn’t in the business of designing large language models — powered by its in-house AI chips — uh–oh.

And on Monday stateside, Meta, a potential kingmaker, appeared to signal that it is considering not just leasing Google’s custom AI chips, but also using them for its own data centers. It seemed like Nvidia felt the need to address some of those rumblings.

The chipmaker said on the social media platform X that its technology is more powerful and versatile than other types of AI chips, including the so-called ASIC chips, such as Google’s TPUs. Separately, Nvidia issued a private memo to Wall Street that disputed Burry’s allegations.

Power, whether in politics or semiconductors, requires a delicate balance.

Remaining silent may shroud those in power in a cloak of untouchability, projecting confidence in their authority — but also aloofness. Deigning to address unrest can soothe uncertainty, but also, paradoxically, signal insecurity.

For now, the crown is Nvidia’s to wear — and the weight of it is, too.

The UK’s Autumn Budget is coming

The run-up to this year’s U.K. Autumn Budget has been different from the norm because so many different tax proposals have been floated, flagged, leaked and retracted in the weeks and months leading up to Wednesday’s statement.

It has also made it harder to gauge what we’re actually going to get when Finance Minister Rachel Reeves finally unveils her spending and taxation plans for the year ahead.

Workday shares slid more than 5% in extended trading Tuesday after the finance and human resources software maker issued quarterly margin guidance that came in below Wall Street projections.

Here’s how the company did in comparison with LSEG consensus:

Earnings per share: $2.32 adjusted vs. $2.18 expected
Revenue: $2.43 billion vs. $2.42 billion expected

The company forecast a fourth-quarter adjusted operating margin of at least 28.5% and $2.355 billion in subscription revenue, according to a statement. The StreetAccount consensus was a 28.7% margin and $2.35 billion in subscription revenue.

Workday’s revenue grew about 13% year over year in the quarter, which ended on Oct. 31. Net income of $252 million, or 94 cents per share, was up from $193 million, or 72 cents per share, in the same quarter a year ago.

Subscription revenue in the third quarter totaled $2.24 billion, with an adjusted operating margin of 28.5%. Analysts polled by StreetAccount had anticipated $2.24 billion in subscription revenue and a 28.1% margin.

During the fiscal third quarter, Workday announced artificial intelligence agents for analyzing employee performance testing financial health, and the company revealed plans to buy AI and learning software startup Sana for $1.1 billion. Also, activist investor Elliott Management said it had built a Workday stake worth over $2 billion.

Workday has seen its stock decline this year as pundits discuss the risk of generative AI tools threatening the growth prospects for cloud software incumbents. Company shares have fallen 9% so far in 2025, while the Nasdaq Composite index has gained 19%.
