All pareve. I happen to have a spare blender jar and blade from an old appliance. Since it fits my current blender base, I made it milchik and use it to make milkshakes and the like. But I would never have bought a second unit just to have a milchik one. You can make milkshakes in a quart jar, and you get the benefit of a little upper body exercise.
I do food prep in pareve to the maximum extent possible. Even when making chicken soup or beef stew, I cut up the veggies in pareve. I don’t think I have ever cut an onion with a non-pareve knife in my life. Why would I? If I cut it pareve, I can steal a slice for my cheese sandwich before dropping the rest in the cholent pot.
You didn’t ask, but the only appliance I have for Pesach is a little handheld electric mixer (not immersion blender) for beating egg whites.
My food processor I use for meat, My blender for dairy and my stand mixer I consider meat because I am not careful enough with washing it in cold water. I dont have a large kitchen and its a lot easier for me to just have milchig and fleishig items.
My big mixer is pareve and I have a hand held small mixer for milchigs. Immersion blender is fleishik. Food processor is pareve. But I’ve recently started washing it with fleishik keilim because it actually encourages me to use it more frequently. I haven’t put actual meat in it.
I treat my food processor as fleishig (cut onions with fleishig keilim), my blender as milchig, immersion blenders for both fleishig and milchig, pareve hand mixer, and fleishig washed Bosch...BUT I'm pretty confident when I can use my appliances for out of the norm needs. E.g. making cheesecake once a year with a pareve mixer and washed without yad soledes bo water keeps my mixer pareve (now I just use my Ninja blender though). I can make pizza dough (which is pareve) in my mixer bowl (washed yad soledes bo with fleishig) and use it for milchig pizza still. I can mix up challah which is perfectly pareve in the Bosch bowl.
