ElI5: Money Laundering: Those US candy shops on UK High Streets, How are they money laundering, what is it and how is it so well known?

Question

In the UK it is widely ‘known’ and accepted that the sweet shops and phone shops on places like the famous Oxford Street are fronts for money laundering. Can anyone explain to me what money laundering is and what these shops are actually doing? How do people know these shops are doing it? I don’t understand.
