'Aruba' is simply the name of the model and/or collection that was most likely "made for" Costco exclusively...with that said the name itself may have only been around a year or two hence the reason you cannot find any info about them especially dating back 15 years...long story short does the jets themselves that need replacement have any type of part # or manufacturers logo on them? or can you simply upload a picture of the jets you need next to a tape measure for size reference? you may be able to use a different brand of jet with no issues
