You said something about fixing the Suction Cup.
Can we repair or only replace ?

yes, pretty much anything can be replaced, i was jsut trying to provide a free option to attempt to fix them.

most LFS can order these or may even stock them. Or you can go online and order replacements. they are not very expensive, and may be needed if the rejuvination prccess does not work well.

I miss that "rejuvination prccess" !
Could you explain that again.

its discussed in detail in the show, but basically, you boil the suctions cups, for a minute or two,..
i have also foudn that if you remove them and quickly place them in cold water it helps..

the boiling can easily be done in the microwave :)
