This product is the "Yukkureaner", a Yukkuri attached to vacuum cleaner. This cleaner is superior to other vacuum cleaners because it converts all the absorbed trash into stale filling (Yukkuri shit).
Too much upkeep, IMO. If you don't vacuum all the time you'd have to feed it to keep it alive and functional...unless they can replace your yukkuri nozzle for free or a low price. It's only worth buying if you want to see the yukkuri suffer.
Maybe the upkeep is kind of excessive, but that can be alleviated by feeding the Yukkuri with the contents of the waste container. However this might lead to having a drooling, peeing and even more retarded Yukkuri, some artists, like M1, state that stale filling cannot be converted to active filling, this leads to mental function degradation and Yukkuri becomes into a shit bag, literally.
