A single robot vacuum for one home costs $549 to $1,399 at retail. To sweep your floor.
A family with two floors buys two units. That is up to $2,798.
And the Clean Base bags run out. Replace them and you pay extra.
Side brushes: $19.99 for a 3-pack on iRobot's own store.
Filters: $36.99 for a 3-pack.
Dirt disposal bags: $12.93 for a 3-pack.
You are subscribing to floor cleaning in 2026.
iRobot was once a $3.5 billion company built on this pricing model. It filed for Chapter 11 bankruptcy in December 2025. A Chinese contract manufacturer named Picea Robotics now owns 100 percent of it.
Now meet OOMWOO.
A free and open source alternative to Roomba.
Created in June 2026 by a California founder named Dr. Ilia Ovsiannikov. Former Samsung engineer. 70 patents. He architected Samsung's second-generation neural inference accelerator for smartphones. Then he open sourced the whole robot.
44 days later the repo has 5,548 stars and 235 forks. No VCs. No paywalls.
Here is what OOMWOO gives you:
- 3D-printed chassis with full CAD files
- 2D LiDAR mapping and SLAM navigation
- ROS2 and Nav2 autonomous cleaning stack
- Native Home Assistant integration for local control
- ESP32 firmware and Raspberry Pi 5 brain
- Gazebo simulator to test before you build
- Apache 2.0 license, fork it, sell it, reuse it
Here is what OOMWOO costs:
The price of the parts you buy yourself. No subscription. Unlimited runs. Unlimited maps.
Roomba stores your home map in the iRobot cloud. OOMWOO stores it on your Pi.
Roomba j-series carries a camera. OOMWOO does not.
Roomba features can be changed by the new owner in Shenzhen. OOMWOO is Apache 2.0.
Here is the wildest part:
In 2020, iRobot Roombas captured a photo of a woman on the toilet. Gig workers in Venezuela labeling the data for Scale AI posted 15 of the images to Facebook and Discord. MIT Technology Review broke the story in December 2022. iRobot has shared over 2 million images with data annotation firms.
Your map never leaves your Raspberry Pi. Your floor plan. Your daily routine.
For one apartment, you save $549.
For a two-floor family, you save $2,798.
100% Open Source. (Link in the comments)
