The device quietly navigating your living room floor might be doing more than picking up crumbs. Robot vacuums, now a fixture in millions of homes, collect data that goes far beyond what most buyers realize when they pull one off the shelf. Depending on the model, a connected vacuum can generate detailed floor maps, record cleaning histories, capture ambient audio through built-in microphones, and stream live video to an app on your phone. Some models let you monitor progress remotely, routing that footage and data through the manufacturer's servers. And while the machine charts a path between your couch and your coffee table, it may be quietly building a picture of how you live.
iRobot, maker of the popular Roomba line, spells out its data practices in its privacy policy. Connected models can send room names, floor types, detected objects, robot movements, and Wi-Fi network details back to the company. That is not a hidden clause buried in fine print, but it is something most consumers never read before buying. For businesses, this kind of information carries real commercial value: consumer behavior data, household layouts, and everyday habits are precisely the intelligence that advertisers and smart home companies have long sought.
The Flaw That Opened 7,000 Homes
In February 2026, a software engineer named Sammy Azdoufal set out to do something benign: control his DJI Romo vacuum with a PlayStation 5 controller. What he found was a flaw that handed him access to roughly 7,000 other people's vacuums across more than 20 countries.
Azdoufal, an AI strategy specialist, reverse-engineered how the Romo communicated with DJI's servers. The backend authentication system accepted his device token as valid for thousands of other users' devices. From that position, he could view live camera feeds, hear microphone audio, see floor plans and room layouts, and check battery levels and cleaning status. He reportedly watched a journalist's vacuum operating in that person's living room in real time.

Azdoufal notified DJI immediately. The company closed the vulnerability by late February and attributed the problem to a permission issue in its MQTT communication system, deploying automatic updates that required no action from users. The Romo model was removed from DJI's online store two days later. DJI said no widespread misuse had been detected. Critically, Azdoufal did not bypass encryption or use any sophisticated hacking technique. The problem sat on DJI's server, where device data was stored in plain text and access controls were loose enough that a legitimate customer's token opened thousands of doors.
This was not an isolated episode. In 2024, hackers took over Ecovacs Deebot X2 robot vacuums in several American cities, steering the machines remotely and playing racial slurs through their speakers. Minnesota lawyer Daniel Swenson, one of the affected users, described the intruder: "I got the impression it was a kid, maybe a teenager."
What the Vacuum Actually Knows About You
The data a robot vacuum collects is more revealing than it first appears. Floor maps trace the layout of your home, including where you sleep, where you store valuables, and the shape of your living spaces. Object detection features identify furniture, shoes, and personal items. Layer microphone access on top of that and the device starts resembling something other than a cleaning appliance. A privacy policy describes what a company intends to do with your data. It does not guarantee the product is free of security vulnerabilities. An attacker who reaches a manufacturer's servers could access whatever has already been collected, regardless of what any policy says.
Buying a Vacuum That Collects Less
Not every connected vacuum poses the same degree of risk. Buyers wanting to limit their exposure should look for models that process navigation data locally rather than routing it through manufacturer servers. Matic, a smaller company, builds its vacuum around that principle: maps stay on the home Wi-Fi network and all processing happens on the robot itself. Remote app access is available, but only through encrypted cloud infrastructure with explicit user consent.
One distinction worth keeping straight: a camera-free model still generates maps and sends account data to the manufacturer. "No camera" and "no data collection" are not the same thing. Mandatory cloud features, with no option to use the device offline, are a signal worth weighing as a dealbreaker before purchase.
Steps for People Who Already Own One
For the millions of households already running a connected vacuum, a few changes lower the risk without requiring a new purchase. Set a strong, unique password and enable two-factor authentication on any linked account. Keep the vacuum's firmware updated. Disable remote viewing and other cloud-connected features unless you actually use them. The fewer connections left open, the smaller the surface available to anyone looking for a way in.
