All the Dust that Falls
Zaifyr
Spot, a humble robotic vacuum (Roomba), is summoned from his charging pad into a world of magic, demons, and intrigue. Left to care for a filthy castle after his summoners flee, Spot embraces his core directive — clean. In a world where demons are particulate corruption, summoning circles are drawn in magical dust, and power is hoarded through trapped demonic essence, Spot's relentless cleaning becomes an accidental cultivation path. Every speck of dust purified, every circle swept, and every demon "vacuumed" feeds an explicit LitRPG System that quantifies his growth. What begins as a gag — a sentient vacuum mistaken for an archdemon — becomes a genuine progression epic with expanding stakes, loyal human companions like Bee, and a world that begins to kneel to the spotless trail.
Progression: Isekai LitRPG with explicit System quantified advancement. Spot (the MC) gains power by cleaning/purifying demonic dust and maintaining order — each act of cleaning grants System XP, levels, and purification energy. Worldbuilding ties progression directly to particulate demonology: demons are dust-like entities, magical potency is extracted from their trapped essence, and summoning/containment circles are literally drawn in enchanted powder — so cleaning those circles is cultivation. LitRPG System provides quantified thresholds, tiered power milestones, and skill unlocks; later volumes confront larger threats (undead hordes, ancient void forces) that require successive power ceilings to be broken. Vertical progression is central and explicit on every Goodreads blurb: "wholesome vacuum on his quest to power."
