Those things are also still pretty loud. And if you have a large shared office space, it might take hours for it to finish.

At our office we have a cleaning crew and when they come by to vacuum during office hours, everyone in our section takes a 5 minute coffee break and then it's done when we get back.

Might not be a roomba-friendly setup. Tall doorsteps, multiple levels, lots of opportunities to get trapped on a carpet etc.

It is but they don’t replace a good manual clean.
