How should broken-pot fragment cleaning be evaluated when buying a rotating clay-pot cooker?

During the trial run, crack a clay pot on purpose, then cut power immediately and see where the shards land. The real test is whether the grate tray, burner guard ring and turntable slot can be cleared by hand or with one simple tool inside five minutes; any crevice that needs the turntable or guard removed to reach should fail, because nobody will strip the machine mid-service. Note the break point, clearing time and leftover spots on the acceptance sheet, and use it to train new kitchen staff later.
