Which IoT device is better: A Roomba or a Dalek?

... here is a quick comparison for those of you in the market to buy ...

Dalek

1. can't ascend a flight of stairs (solved in 1988[1])
2. aware of its surroundings
3. equipped with plunger useful for unblocking backed-up sinks
4. kills any carbon based life-form (pet or otherwise)
5. highly intelligent yet can not be trained
6. can do any job that requires killing or being rude in general

Roomba

1. unable to ascend a flight of stairs
2. oblivious to its surroundings until it creates a map of the environment (occasionally gets lost in the neighborhood)
3. gets along well with pets from the same household
4. as dumb as a pocket calculator with wheels (but can be trained)
5. has 1 job in which it sucks
6. natural predators: unknown
7. power source: 22.5V 1.25A AC
8. Android/iOS app: yes

?? Conclusion ??

While Daleks seem great for solving any plumbing emergency, and theoretically hold the key to renewable energy, their hostility toward all organic life forms makes them a challenge to live with.

The Roomba therefore is a clear winner, especially for young families, or if you have pets.
