Oomwoo is a new open-source robot vacuum you can 3D print yourself, sidesteps cloud security risks by running fully offline — project combines Raspberry Pi, 2D

Raspberry Pi, ROS 2, 2D LiDAR, and a 3D-printed chassis, but no build instructions yet.

Right now, oomwoo is at the request-for-comments stage, with the current v0 milestone covering a 3D-printed chassis, a ROS 2 Gazebo simulation, and LiDAR mapping with manual SLAM, and the compute choice between a Raspberry Pi 5, an ESP32 running micro-ROS, or both is still open. Planned deliverables run from the bill of materials and printable files to firmware and a custom PCB, with the first BoM targeted for around mid-July.

A convenience kit will be sold through Maker's Pet, but Ilia says that buying it won’t be a requirement, and every part can be sourced independently.

The inclusion of local control could be a boon for getting more tinkerers and enthusiasts on board with the vacuum, following several examples of robot-vacuum security failures over the last few years. At DEF CON 32 in August 2024, researchers Dennis Giese and Braelynn Luedtke showed that several Ecovacs models could be hijacked over Bluetooth to reach their cameras and microphones, with Giese telling TechCrunch the security was “really, really, really, really bad.”
