First let me say I paid for this product because I thought it would be great for cooking indoors in summer and it has more than exceeded my expecttions!  It's easy to use, easy to clean, and you can make a full meal in it for 2 people.  I make fries, burgers, chicken, toast, bagels, roasted brussel sprouts and other veggies.  I unplug mine after each use, wait til it's cool then wipe the interior with a clean damp microfiber cloth so that grease does not build up on the inside.  

If you wipe it out after each time you use it, it will air fry, roast and bake anything like a dream. The interior walls are ceramic coated, so if you think this is excessive, it's easier than cleaning a skillet, and you have to wash the cook basket and pan anyway.  Just one additional step.  I loved it so much I bought for my daughter for Christmas and she loves it as much as I do.  Just remember that excellent products are not cheap and cheap products are not excellent.  You get what you pay for.
