The set up is interesting. A roomba gets isekaid to a new world and is mistaken for being insanely powerful. Proceeds to get insanely powerful by cleaning the castle. The first half was paced better than the second half. After they go into the catacombs, I find the story beginning to drag. We learn about the levelling system after the fact. Will probably continue to book 2. How book 2 will determine if I continue with the series.
