Product review (2 stars): I know a BETTER VENT!
I'm not sure if this is the exact lint trap that uses water that I had and used, but I did not like having to physically carrying this thing with dirty water to an outside ditch....after which I had to rinse vigorously.  For the money, you will be better off getting a BETTER VENT, which uses NO WATER.  Look it up here on Amazon and you'll see what I mean.  I like the BETTER VENT and for all practical purposes I would call it the BEST VENT!  The BETTER VENT is very easy to install, and you don't have to remove the whole box to empty the lint!  Once a week I vacuum the inside area of the BETTER VENT, as well as the FILTER.  The filter is replaceable, but not 'washable' or 'rinseable' but vacuuming it works well for me.  I've had my BETTER VENT for almost two months and am VERY PLEASED with it.  I bought six extra filters, but haven't changed the original filter yet.  On top of the unit there is a small door which swings up to indicate that the filter needs attention.  If you vacuum it once a week, like me, you'll have no problem.  I don't think there's anyone near us, who washes and dries as much clothes as we do!  I was a skeptic at first, and thought that the BETTER VENT was a bit 'pricey' but I can tell you that it's well worth the investment!
