Oomwoo: Build your own open-source robot vacuum for under $200

Maker's Pet has unveiled oomwoo, an ambitious open-source robot vacuum designed for the maker community. The project is fully open — hardware, firmware, and software — with a 2D LiDAR sensor for mapping and autonomous navigation using ROS 2 and Nav2. It runs locally with native Home Assistant integration, requiring no cloud for daily operation. The chassis is 3D-printable, and the bill of materials is fully documented so you can source every part yourself. The target budget for components is $100–$200 (plus a Raspberry Pi 5), a fraction of the cost of a mid-range commercial vacuum.

The project is organized into self-contained modules (simulation, dust bin, fan assembly, etc.) so the community can build in parallel. The GitHub repo includes URDF models, Gazebo simulation, and contribution guidelines. Maker's Pet will also offer a convenience parts kit for those who want to skip sourcing. oomwoo is currently in early development (v0), but the goal is a reliable, home-appliance-quality vacuum that users fully control. Future extras include cloud features and an app store for custom ROS 2 behaviors, but the core stays local-first.
