Why do we need a cleaning and rinsing sink if we are moving away from manual to automated processing, particularly if space is a problem?

Even when using an automated system, there are likely to be some instruments that cannot be cleaned in this manner. Therefore, manual cleaning is required for these instruments and for occasions when the automated system is unavailable. The preferred method for manual cleaning involves the use of two sinks, one for cleaning and one for rinsing, or a sink and a basin as a short term temporary measure.
