I use the Ninja Foodie XL and it is much preferable to my mom's Cosori. It has a bunch of extra functions, holds more, cooks more evenly, and, in my experience, smokes less. For clean up we a) cover the drip tray with tinfoil/parchment paper* b) use a scrub brush that holds dishwashing soap to easily get between the holes in the grate tray. Absolute worst case, we soak the grate tray while we eat, but that's only for bacon grease. These easy tips that are all over Internet air fryer articles. Anyway, I hope you come to enjoy yours better.
*Unless your food is extremely greasy, a tinfoil covering last quite a few cooking sessions!
