Robot scrubbers already run the open floors in airports and big-box stores. Restrooms and spills still get cleaned by hand, and at janitor pay, robots are slow to win on cost.

Building Cleaner (Janitor): what AI changes and what stays

Robots that scrub floors are already common in large buildings. What keeps a cleaning crew employed anyway is that most of the job, bathrooms, furniture, a sudden spill, isn't floor-scrubbing, and this work pays little enough that a robot has to be genuinely cheap to be worth buying.

If robots already clean floors, why does this job stay?

Robots that scrub large open floors are already working in big commercial buildings, which has really changed that one specific task. But most of a cleaner's actual work is bathrooms, furniture, and cleaning up whatever unexpected mess shows up that day, tasks a floor-scrubbing robot was never built to handle.

Why is cost such a big factor for this particular job?

This work is generally paid close to minimum wage, so a cleaning robot has to be quite cheap to actually save a building money versus a person, and that math takes years to work out even once the technology exists. Meanwhile, someone still has to notice a hazard or damage while cleaning and work around people without disrupting them, which is easier for a person than a machine.

If you're working in or entering building services, what should you build?

Get familiar with whatever automated equipment your building already uses, since being the person who operates and troubleshoots that equipment is more secure than doing only manual tasks a machine could eventually take over. Reliability and attention to detail, noticing damage or a hazard before it becomes a bigger problem, are also the reputation that keeps a cleaner's job secure regardless of what equipment shows up.
