not exactly....
ice and herb gets washed like clothes - small load, cold-cold, but then the outflow from the machine, instead of going into the sewer, goes into a barrel with filters. the green stays in the first (crudest) filter, and then comes the bubble hash - and at the bottom of the barrel is the 'waste water' - which you then treat like spinach juice (which is, btw, the way the ganja tastes after the wash).
its sorta the opposite of a dirty wash in the laundry
