Will this attach to a Ninja T bar? How about the Ettore swivel T Bar? Does it actually work? Looks like it won't make contact to the glass unless you're nearly parallel to it. Thanks!

This Click and Scrub pad is only truly compatible with Moerman T-Bars, but it does add some extra scrubbing power to your scrubber sleeves! It can be flipped around to lay under/over the sleeve itself. The pictured configuration is the standard design. 

Hi im trying to connect the scrub pad with no success to the moerman t bar.. Any tips?

Start with one of the tabs lined up with an open slot on the T-bar, then you should be able to push down and it will click right in.
