Below is the manual for the pump based vacuum suction cup shower caddy and soap holder that Bunnings sell – “Fusion-Lock” brand I think, but the pump instructions are branded EVOVAC. The attachments have a one way valve and it comes with a blue / teal pump that allows you to remove some of the air from the suction cup giving it a much better hold.
The good: They stick like glue if applied to perfectly smooth clean gloss tiles.
The bad: If you don’t clean the surface very well, or if your tiles aren’t perfectly gloss smooth, then it won’t stick.
The ugly: The “stainless steel” rusts in less than 6 months.
Given they were a bit pricey, I was hoping for better quality with the stainless steel.
