Kitchen Blenders

I am a little confused as to what gadget does what. Basically I want to know if a Smoothie Maker is like a blender, or just for making smoothies only? Also I am after a Juicer – do any of these contraptions double up i.e. smoothie maker/juicer/blender!!! Can anyone recommend some good tried and tested machines please, many thanks
Yes I am in the UK

I don’t know if they sell it in the UK, but there is a product out there called the "Magic Bullet."

It is amazing, and it comes with attachments that make it usable as a juicer, blender, AND smoothie maker.

Otherwise, go for a blender over a smoothie maker. They have more versatility and can be used for smoothies as well
