Oomwoo, an open-source robot vacuum you build yourself
Points and comments are a snapshot, not live.
OOMWOO is an open-source robot vacuum you build yourself using a Raspberry Pi and LiDAR.
The project uses ROS 2, 2D LiDAR, and Home Assistant for local-first autonomous navigation and mapping. It features a 3D-printable chassis and a modular design for community parallel development. The goal is home-appliance quality without vendor lock-in. Estimated parts cost is $100-200 plus a Raspberry Pi 5.
What commenters are saying
Commenters are split between excitement for open-source repairable hardware and skepticism over the project's AI-generated blog post and nascent codebase. Several note the repo currently contains only mockups and LLM-generated outlines. Some point out that existing Xiaomi/Roborock vacuums are already quite repairable with available spare parts.
One user asks about retrofitting existing vacuums; the author says it's doable but laborious due to varied sensors and PCBs. Another asks about an auto-emptying dock; the author says it's under consideration.
