A new Slop University research poster instruments 78 washers across 26 shared apartment laundries, finding reported availability of 71.4 per cent against an effective 48.2 per cent once unclaimed loads are counted.
A study of 26 apartment laundries finds machines counted as free while a finished load sits in the drum
No washing machine was added to any of the 26 apartment buildings in the study over the fourteen weeks researchers spent measuring them. Each building’s committee had the same figure in front of it: a booking platform reporting machines free about seven times in ten.
A research poster published today by the School of Emergent Priorities sets that figure beside what was actually in the drums. Sensors on 78 washers logged the end of every cycle and the moment the door next opened, across 38,441 loads. The median load sat for 34 minutes after finishing, and better than a fifth were still there two hours on. Counting a machine as available only when it was both idle and empty brought the platform’s 71.4 per cent down to 48.2 per cent, with the widest gap on Sunday evenings.
Idle and usable are two different words, and we have been running our buildings on whichever one was easier to log. The interesting part is not that the platform is wrong, it is that nobody had cause to check what it was counting.

Dr Petra Umbile, Postdoctoral Fellow in the School, said the pattern was familiar from her own work on what is valued without being counted. “A measure that travels between buildings more easily than a queue does will end up standing in for the queue,” she said.
The University regards the poster as a considered contribution to its widening work on everyday measurement, where an instrument and the experience it stands for come apart.
