is food processor necessary?

I was told can just use normal blender, or use masher to mash after steaming... But having toiled in a stuffy kitchen for like 30 minutes and struggling to scrap pears (n other fruits) or trying to blend some leafy veg, i was v glad i finally took out my steamer blender to use. Now my kid has teeth and i still use it to steam & blend baby spinach, make pasta sauce etc.
