easy to diagnose

The pedal fell to the floor because there was no pressure in the clutch hydraulic system. It is very likely that the hydraulic system somehow is leaking.
When the slave cylinder fails, it will leak hydraulic fluid on the floor. When the master cylinder fails if doesn't leak, it just fails to push the fluid. A punctured clutch hose is obvious (by the wheezing sound) if on person stands at the open engine bay and another pumps the clutch pedal.
These seem to fail regularly on 9000's, at ~100K-120K miles, generally they are replaced with the clutch (which wears at a similar rate).
Directions for replacing the clutch are at the link below. The clutch needs to be bled with higher than atmospheric pressure (thus the pressure bleeder your machanic was using).
regards,
NT
