Does anyone with cats use a Diaper Genie (or similar) for disposing of soiled litter?

When the building we live in went in to foreclosure, the bank removed our dumpster. Garbage is only collected once a week, so we have had quite the issue with dirty litter. We're only allowed to put garbage out on Monday nights, so we have no choice but to keep it in our spare bedroom. Flushing isn't an option.

So, does anyone here use a Diaper Genie (or another product like it) for dirty litter? If so, how does it handle the smell? I know parents love them, but I'd love to know if someone here uses one and how they think it works? I'd love to have my spare room back, instead of storing garbage in it.
