Happykeeper floors

Hi all, and a Merry Christmas!!

Has anybody here used the "Happykeeper" floors? These are the ones with the large diameter plastic tubes.

A Google search comes up with unsubstantiated claims that using these floors, you don't need any varroa treatment for years on end. I wish!!!

Seriously, has anyone had any real-life experience with them? For instance how on earth do you keep them clean? Boiling water, or do they melt?

Hi Yes I've used them now for a good few years and wouldn't spend my money on them / cleaning? yes I know what you mean / soak them in a basin of soapy water then rinse with dish cleaning brush and cold water. L.
