While it comes across as an obvious cash grab, the cassette is a compelling feature if you consider that it does 30 washes and has its own memory of how many each has left. While it is 2x-3x the cost of traditional dishwasher pods, they are focusing on convenience — all the way down to automatic delivery and return — which deserves to be recognized as innovation in end-to-end product design, service, fulfillment, and product lifecycle.
Does someone come into the house and change it out?
I spend a lot more time (still not much) loading and unloading the dishes than I spend acquiring and pouring powder, so I'm not sure what value I'm supposed to think this would provide.
You can have about the same experience with standard tablets though and none of the wasteful shipping and plastic cartridges. The dishwasher can be online (for those who want it) and report back the amount of washes (the backend can calculate the amount of washes per week to predict when you're going to run out) so that the manufacturer can send a new box in advance.
Make it last something like half year and I'm keen. Packaging in regular shops isn't particular great either. Hand soap and tooth paste being worst. The amount of packaging we throw with food is completely crazy.
