A good air fryer should have a pan/grill that's detachable from the fan/heater section. The pan/grill should fit entirely in a sink.
If you get an air fryer that's the size of an oven it will be as hard to clean as an oven and will take just as long to heat and cook as an oven since internally the tech is 100% identical to a fan forced oven (a heating element with a fan). Don't make the mistake of bigger is better for an air fryer.
Air fryers are meant to be small pots that have a fan forced oven element bolted to the top that can easily be detached for washing in the sink. That's the whole appeal of it. It's a teeny tiny oven that heats up extremely quickly for little power due to its size. It's easy to clean because the non-electronic part fits entirely in the sink. It's only the size that gives air fryers an advantage. If you buy an air fryer the size of a fan forced oven you have literally just bought a less good fan forced oven.
