Just remember to replace cartridge every 2-3months no matter # of flushes
In terms of usage, this system requires some getting used to. It works well when there is "weight" after each use, i.e. the flush (suction and twist) needs the weight to operate well. I dump 1-2 cup of cat litter down each time and this has worked well.<br /><br />More importantly, and don't make the same mistake I did - regardless of how many flushes you've done (spec says 10-15 flushes), always always replace the cartridge after 2-3 months. Otherwise the bag will biodegrade and you will have a mess to clean up!<br /><br />This interval varies depending on many factors such as air temperature. I left mine after a few trial use for 5 months and liquid leaked out into the white plastic bucket. At first there was no smell, over time I noticed the faint smell that grew worst and upon investigation found liquid in the white bucket. This came through two layers of bags - the tinfoil twisty bag and the black garbage bag, both came with the cartridge purchase.<br /><br />The takeaway is to always replace the cartridge after some fixed amount of time even if you've not flushed 10-15 times.
