Key takeaways
- Guarantee completed tasks per shift, not top speed on an empty aisle.
- Write site assumptions and exclusions before acceptance testing.
- Pick measurement tools both parties trust and audit monthly.
- Remediation windows should name who fixes what and by when.
- Remedies stay practical: credits, extra training, or route tuning, not fantasy penalties.
Why do speed specs fail as guarantees?
Brochures quote meters per minute on perfect floors. Your building has ramps, mats, guests, and pallets that move every week. Performance contracting for robots must track completed work, not ideal machine speed.
The direct answer: define productivity guarantees as verified tasks finished per route or shift, with clear site assumptions, exclusions, measurement method, remediation window, and remedy if results miss target.
Buyers get predictable coverage. Vendors avoid promises they cannot keep once real traffic appears.
The contract should read like an operating plan your night lead can execute, not a marketing slide.
What belongs in site assumptions?
List floor type, slope, doorway widths, elevator rules, operating hours, and who clears obstacles before the robot runs. Assumptions are the baseline for every later dispute.
Name chemical approvals, water fill locations, and who owns spill response. A guarantee written for bare concrete fails on heavily coated tile.
Update assumptions after remodels. Silent layout changes void informal promises even when contracts stay silent.
Which exclusions keep guarantees honest?
Exclude force majeure, utility outages, network failures outside the robot VLAN, and deliberate route blocks by staff. Exclude days when the building is closed for emergency repairs.
Exclude tasks outside the mapped zone. A scrubber guarantee on level one should not cover a mezzanine added mid contract without a new map.
Exclude misuse: wrong pads, unapproved chemicals, or docks moved without integrator notice.
How should you measure completed work?
Autonomous scrubbers report square footage and runtime logs. Compare those logs to physical spot checks on a sample of nights.
Delivery and patrol robots need task counts: stops made, loops completed, alerts generated. Define minimum acceptable quality per task, not only quantity.
Third party ATP or gloss readings can supplement floor care guarantees when both sides agree on sample points.
- Exported fleet logs with timestamps.
- Manual audit nights per quarter.
- Photo or ticket proof for missed zones.
- Shared dashboard both parties can access.
What remediation window is fair?
Give the integrator a defined period to tune maps, adjust schedules, or swap consumables before remedies trigger. Thirty days after a documented miss is a common starting point for new routes.
Name escalation: remote triage first, then on site visit, then loaner hardware if uptime is part of the deal.
Remediation excludes buyer caused issues. Logs should show fault codes and responses.
What remedies can both sides administer?
Service credits against monthly robot rental beat vague penalty language. Extra training sessions for night staff often fix misses faster than cash.
Route revisions and added no go zones are remedies when traffic patterns change. Buyout or return rights belong only when repeated misses persist after remediation.
Keep remedies proportional. A one night slip on a holiday weekend should not trigger fleet return.
How do guarantees differ by robot type?
Cleaning guarantees usually cite percentage of mapped area completed per scheduled run. Delivery guarantees cite successful stops within time windows. Patrol guarantees cite completed loops and alert handoffs.
Warehouse AMR guarantees cite moves per hour with payload and aisle width stated. Cobot cells cite cycles per shift with quality checks defined.
Mixing types under one generic uptime clause creates arguments. Split schedules by category.
Security patrol contracts should define false alarm handling so guards know when human response is required versus log only events.
How do staffing changes affect guarantees?
Guarantees assume trained staff follow start and dock procedures. When turnover spikes, missed starts look like robot failures in the logs.
Build training refresh into the contract when guarantee periods renew. One refresher per season is cheap compared to a dispute.
Name a facilities owner who receives monthly reports. Absent owners let small misses compound.
What role does integrator service play?
Remote triage should be in scope when guarantees are on the line. Slow ticket response eats remediation days.
On site dispatch SLAs belong beside productivity targets. A robot that cannot be reset at two in the morning fails the guest experience even if weekly averages look fine.
Spare units or loaner clauses protect guarantees during parts delays.
How should legal and operations collaborate?
Lawyers draft enforceable language. Operations drafts measurable tests. Bring both groups into acceptance week.
Avoid copying manufacturing OEE clauses verbatim. Service robots face public traffic lawyers rarely see on factory lines.
Keep the appendix in plain English with a glossary for fault codes.
Who signs off at acceptance?
Run site acceptance testing on agreed routes before guarantees start. Sign a log that lists map version, chemical set, and staff trained.
Guarantees should start the week after acceptance, not the day boxes arrive.
Professional service robot deployments keep growing, with IFR reporting more than 205,000 professional units registered in 2023. More buyers now ask for performance language because fleets are larger and audits are stricter.
What belongs in the contract appendix?
Attach the measurement spreadsheet template, escalation phone tree, and sample log exports.
Reference maintenance included scope so buyers know which parts failures pause the guarantee clock.
Renewal should revisit assumptions, not only price.
Store signed acceptance logs with the lease file so renewals start from facts, not memory.
Where does Service Robot Co. fit performance contracts?
We draft guarantees around completed work on your actual floors, not brochure tours. Deployment, training, and nationwide service sit with the same partner that signs the measurement appendix.
A free site assessment can list assumptions and exclusion candidates before legal review. The goal is a guarantee your night manager can explain without a lawyer on speed dial.
