The owners of Roomba robot vacuums have complained the devices appear drunk.
Problems include the machines spinning around, constantly recharging or not charging at all, and moving in strange directions.
The devices maker, iRobot has acknowledged its update had caused problems for a limited number of its i7 and s9 Roomba models.
However, it added a fix would take several weeks to roll out worldwide.

In the meantime, the firm is asking those affected to share the serial numbers of their devices so it can remove the most recent update.
A poster listed numbers of problem including their Roomba:
- travelling diagonally away from its charging dock
- recharging five times while cleaning one room but only for a total of eight minutes
- spinning around and bumping into furniture
- moving in weird patterns
“We’ve worked with impacted customers to roll their robot’s software back”.
“We are also implementing an update to ensure any similar issues are avoided moving forward. This update is being deployed to all customers over the course of the next several weeks”, iRobot said in a statement.
