ROI Comparison
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 | AgiBot X2 Ultra | Walker S1 |
|---|---|---|
| Investment | $54,514 | $75,000 |
| Payback period | 13.1 mo | 18.0 mo |
| Net savings (5 yr) | $195,486 | $175,000 |
| ROI (5 yr) | +359% | +233% |
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.
