A software update that made people’s Roombas act like they’re drunk may not be fixed for several more weeks.

After updating to firmware 3.12.8, customers started reportingtheir Roombas behaving strangely. Some were wandering around like they were drunk, bumping into furniture, taking much longer than they should to clean an area, recharging several times more than necessary, not being able to go back to their charger and getting stuck in the middle of a room.

iRobot reached out to The Verge and said some i7 and i9 robots were impacted, with a software update being responsible. The company is working on a new software patch that should fix the issue, but it’s only expected to roll out “over the next several weeks.”

In the meantime, it looks like Roomba users will have to break out the old Hoover.
