Will the battery kill it like the Roomba got killed?
The Roomba got killed because nobody wants to replace a $100 proprietary battery. (Now the Roomba-maker is off making robots for the US military, where cost isn't an object and battery replacement is done to mil-spec.) Roomba batteries die and then the whole device gets thrown away --- if Dyson doesn't address the battery issue, their product will die too --- no matter how whiz-bang it works.
Double-A's Forever!!!
