Same operating assumptions across every robot — the only difference is price. Set your numbers once to see which pays back fastest.
Annual labor displaced (per robot): $50,000
| Metric | Kirobo Mini | Zeroth M1 |
|---|---|---|
| Investment | $474 | $2,499 |
| Payback period | < 1 mo | < 1 mo |
| Net savings (5 yr) | $249,526 | $247,501 |
| ROI (5 yr) | +52643% | +9904% |
Estimates labor-cost displacement only — not a full total cost of ownership. Actual ROI depends on integration, maintenance, training, downtime, and task fit. Converted currencies are indicative; USD is the price of record.
