Combine the onion, celery and carrot in the bottom of the slow cooker. Add the bay leaves and sprinkle the cloves over the top. Pour in the apple juice and water.
Place the corned beef on top. Cover and cook on low for 8 hours, turning it over halfway through if you can.
When ready to serve, transfer the corned beef to a cutting board and let rest for a few minutes. Slice across the grain and pile onto sandwiches.
