Oleoclean Pro is a smart semi-pro fryer that automatically filters the oil. Once your frying is done, turn off the appliance and turn the dial to "automatic filtration". When the oil starts to cool down, it will go through a sieve before being drained into the oilbox underneath. Thus, your oil will always be clean and can be used many times. Every time you cook with your fryer, the oil is being filtered by a metallic sieve and that's how you get crispy homemade French fries for everybody. It also features an exclusive cool zone system, so no leftovers get burnt and you don't experience unwanted smells during cooking.
