Yes, you can use vegetables in your juicer. Remember to peel them before putting it into your juicer.
However, if you are using vegetables that contain a lot of fibre (such as celery and wheatgrass), you may need to clean your appliance immediately after juicing. We recommend cleaning your appliance after juicing every 200 grams of high-fibre vegetables. Otherwise, the performance of your appliance may be lower than usual.
