Today I’m kicking off my most ambitious Maker’s Pet project yet: oomwoo, an open-source home robot vacuum that you can build yourself. Open hardware, open firmware, open software — and built in public, from the first commit.
No cloud required. No vendor lock-in. It maps your home with an affordable 2D LiDAR and navigates on its own, runs locally, and integrates natively with Home Assistant. If you’re into Raspberry Pi, ROS 2, 3D printing, or just the idea of owning a vacuum you fully understand and control — this one’s for you.
About the name: “oomwoo” is a rotational ambigram — it reads the same flipped 180°, just like the robot itself roaming your floor in every direction.
oomwoo is a build-it-yourself robot vacuum designed for the maker community:
Optional extras — cloud features, and eventually an app store of ROS 2 apps to customize how your vacuum behaves — will layer on top. But the core promise never changes: the vacuum always works cloud-free and local, out of the box.
This is genuinely early — and that’s the point of building in public. The first milestone (v0) is a bare-bones, working build:
The open-source deliverables I’m working toward: bill of materials, 3D-printable files, ROS 2 packages, firmware, a motor-driver and sensor PCB, full build / bringup / troubleshooting docs, and demo videos.
oomwoo is organized so the community can build it in parallel. The robot and its software are split into self-contained modules. You pick whatever module interests you, work on it whenever you want, and submit your work as a pull request. Multiple people can tackle the same module — the best solution surfaces over time.
Modules ready to start right now include:
If you’d like to jump in, the GitHub repo has the module list, the architecture doc, and contribution guidelines.
I’ll be sharing progress, dead ends, and wins as they happen:
Open-source robot vacuum community build updates
Everything about oomwoo stays open — you can source every part yourself. If you’d rather skip the parts hunt, a convenience kit (motors, PCB, brushes, gaskets, LiDAR) will be available here at Maker’s Pet, from the same maker behind this project. The kit is a convenience, never a requirement.
