Some robot vacuums can collect floor maps, cleaning histories and other household data, raising privacy concerns first reported by Engadget. A backend permissions failure let one customer access roughly 7,000 robot vacuums rather than only his own, showing that privacy concerns extend beyond data collection to device access controls in the home.

Robot vacuums that allow remote progress checks may communicate through manufacturers’ servers. Maps and video can reveal details about a home, though the data collected and where it goes vary by model; not every connected vacuum records everything or sells maps.

When Sammy Azdoufal tried to control his DJI Romo remotely, he gained access to and control of roughly 7,000 robot vacuum cleaners around the world, rather than just his own. The server recognized a legitimate customer but failed to restrict that customer to their own device. DJI said it resolved the backend permissions issue with two updates on February 10, 2026.

Azdoufal used Claude Code to help reverse-engineer the communications, but the underlying weakness was in the security checks, not the AI. A complex password would not fix that failure.

Routine data collection is another concern. iRobot’s privacy policy says connected models may send room names, floor types, detected objects, robot movements and Wi-Fi network details.

There is no clear, established privacy-friendly winner. A model should minimize information leaving the home; buyers can check for on-device navigation and image processing, how diagnostic data is shared and whether cloud features are mandatory.

Matic’s privacy policy describes a local-first setup: maps are streamed to the app over home Wi-Fi, and processing takes place on the robot. It says remote app use can transmit data through an encrypted cloud connection only with explicit consent, and only authorized support can involve sharing audio or video.

A camera-free model can still generate maps and send account information, while a privacy policy does not prove that a product is unaffected by security flaws. An attacker might still access existing data even if a company does not plan to share it. Owners can set a strong password, enable two-factor authentication, keep firmware up to date and disable remote viewing or other connected features when they are not needed.

Plug-in vehicles reach 32% of global registrations in September

Plug-in vehicles reached 32% of global registrations in September, first reported by Cleantechnica. Battery-electric vehicles accounted for 23% of registrations and set a record at 1.54 million, up 8% year over year, while plug-in hybrids fell 9%; year to date in 2026, BEVs were up 12% and PHEVs down 10%.

Global plug-in registrations rose 3% year over year to around 2.16 million in September, close to the all-time record of 2.17 million set last December.

Year to date, plug-in registrations were up 4% year over year: BEVs grew 12%, while PHEVs fell 10%. Their combined share for 2026 stood at 25%, with BEVs at 18% and PHEVs at 7%. The overall growth rate therefore hides a clear split between the two categories.

The Tesla Model Y led the model rankings with a record 165,000 registrations, up 17% year over year. Tesla Model 3 came second with 65,000, enough to move ahead of Geely Xingyuan and BYD Song despite a 4% annual decline.

BYD Song finished fourth at 54,519 registrations, up 19% and the fastest growth rate among the top five. An export push and the new-generation Ultra body helped lift the model.

At the make level, Tesla had a record 232,000 registrations, up 9% year over year. Toyota reached 61,332 for its fourth record in a row, finishing ahead of Volkswagen’s year-best 58,000 to become September’s best-selling legacy make.
