Your robot vacuum is doing more than picking up crumbs from last night's midnight snack. It's drawing a map of your life. Every hallway, bedroom, and furniture layout, uploaded to a cloud server you didn't choose and definitely don't control.
This isn't a niche problem. Over 10% of U.S. households now own a robot vacuum, a number expected to double within five years. The three biggest brands (iRobot's Roomba, Ecovacs, and Roborock) control roughly 60% of the global market. Nearly 70% of all units sold are cloud-connected. That's a lot of floor plans in a very small number of hands.
The Digital Floor Plan You Didn't Consent To
To you, the map helps the vacuum find the rug. To a data broker, it's a dimensionally accurate interior layout of your private life. Around a dozen manufacturers now ship vacuums with front-facing cameras, and the data pipeline behind them is exactly as leaky as you'd expect.
In 2020, images from iRobot's Roomba J7 series were sent to Scale AI for labeling and ended up on social media, posted by gig workers in Venezuela. One photo showed a woman on a toilet. iRobot confirmed they came from development units, but the supply chain that made it possible (manufacturer to AI trainer to offshore contractor to Facebook) is standard architecture.
Then there's Ecovacs. At DEF CON 2024, researchers demonstrated they could hijack Ecovacs Deebot X2 vacuums and access the live camera and microphone with no indicator light. Weeks later, real-world attacks hit multiple U.S. cities. Hacked Deebots started shouting racial slurs at families. One chased a dog around a Los Angeles living room. Ecovacs describes the source of its AI training data as "confidential."
And iRobot? It filed for Chapter 11 bankruptcy in late 2025 and is being acquired by Picea Robotics, a Chinese manufacturer. The company that had your floor plan now has different owners. Same data.
What a Local-First Setup Actually Looks Like
The fix isn't complicated. It's just not the default, because the default is designed to benefit someone else.
Cloud independence. Tools like Home Assistant and Valetudo keep floor maps on hardware you own. Valetudo supports a range of Roborock and Dreame models for fully local operation. The vacuum cleans. The manufacturer gets nothing.
The "invite-only" rule. No local-only mode, no spot on the network. Worth noting: Roborock stores maps on the device by default, while Ecovacs stores them locally and in the cloud. Read the fine print, or better yet, don't rely on it.
Hard termination dates. When a vendor stops pushing security updates, that's the device's expiration date. Factory reset. Off the Wi-Fi. Norwegian researchers found that even vacuums claiming end-to-end encryption leaked 8% to 26% of network traffic unencrypted. No patches means an open door.
Your floor plan shouldn't be a line item in someone else's dataset. One in ten American homes is running a robot vacuum. The odds are decent yours already is.
