Three Year Robot Lease End: Condition Checks to Plan

What should a team check when a robot lease ends?

When a three year robot lease nears its final months, the goal is simple to state. The unit has to come back in good condition, and that condition has to be provable on paper. A facility team should check battery health, brushes and wear parts, sensors, software versions and the handover record before the term closes.

Most of these checks take an afternoon with a written checklist and a trained technician. The purpose is to find gaps while there is still time to book service, not on the morning the unit is collected.

Read the return condition terms in your agreement early. Our research did not turn up a published industry standard for lease return condition, so the signed agreement is the reference point for what good condition means.

Why does battery health come first?

The battery is the part most likely to age without obvious warning. Run time shrinks by degrees, and a shift that once finished on one charge may start needing a mid shift top up. Test run time on a full charge, note the charging duration, and check the service log for low battery warnings.

Vendor figures give a sense of scale, though none is a commercial robot specification. Dreame, a consumer robot vacuum brand, says its batteries are rated for about 500 full charge and discharge cycles, with a slight decline after 2 to 3 years of daily use. CNS Battery, a battery maker, claims 3,000 to 5,000 complete cycles at 80 percent depth of discharge for cleaning equipment in general, which it says means 5 to 7 years of service in typical use.

Those two claims sit far apart, and the gap is a reason to measure rather than estimate. A three year term may fall inside a 5 to 7 year claim, yet only your unit's health data settles the question. CNS also says fleet dashboards can show battery health, state of charge and remaining cycle life, so ask whether your model reports those figures. A PROPOW article on short battery life in floor scrubbers covers the problem but, in what we reviewed, gives no cycle or state of health figures.

How should brushes, pads and squeegees be inspected?

Wear items are where return inspections turn subjective fastest. Bristles, pads and squeegee blades lose performance gradually, and a worn brush can leave streaks that look like a floor problem when the machine is the real cause.

Measure what you can. Compare brush and pad thickness with the maintenance manual for your exact model, note any uneven wear on one side, and photograph the squeegee lip under good light. We did not find manufacturer replacement thresholds for these parts, so wear limits should come from your model documentation, not from a general guide.

What does a sensor check cover?

Sensors decide whether a scrubber slows, stops or turns around near a ledge, a cart or a person. Dirty or scratched lenses, cracked bumpers and misaligned housings can throw faults that look like software trouble.

Clean each sensor window, look for cracks, confirm the bumpers move freely, and run a short test route past a marked edge. Save the fault log from that test. A clean log from a dated test is stronger evidence than a verbal assurance.

Which software versions belong in the record?

Software is the item most often missing from a return. Record the firmware version, the map or route file version, and any configuration changes made during the term. For every update, note the date and the person who approved it.

Ask whether any update was rolled back, and whether the unit still holds a map of your site. Maps reveal layout details, so agree with the provider whether the map is exported to your records and then removed from the unit before pickup.

What should the handover record contain?

The handover record turns the inspection into fact. It should be dated, signed by both parties and tied to the unit's serial number, because a photo without a serial number is hard to use later. Include at least these items:

Keep copies at the site and with the provider. If an item is disputed later, the record should show what was agreed on the day, not what people remember afterward.

• Serial number, model and total run hours from the unit's logs
• Run time test result and any battery cycle count the unit reports
• Brush, pad and squeegee condition with measurements and photos
• Sensor cleaning, test route result and attached fault log
• Firmware, map and configuration versions with update dates
• Maintenance and repair history for the term, including open faults
• Map export and data removal confirmation
• Signatures from the facility and the service provider

How should the final months be planned?

Begin condition checks well before the last month so there is time for service visits and replacement parts. A mid term inspection lets the team fix faults early, and a final check at pickup confirms the state the unit is in when it leaves.

Service Robot Co. leases robots through financing on a three year lease, with one fixed payment quoted after a site assessment. We service each unit through our nationwide US engineer network, so end of term conversations stay on returning the unit in good condition.

If a check finds a problem, document it as carefully as a passed check, agree the repair path in writing, and book service early. A fault found early in the final months is far easier to resolve than one found on pickup day.

Where do return disputes usually begin?

Most disagreements start with a blurred line between normal wear and damage. A worn pad after a full term is expected in many cases, while a cracked housing or a missing sensor cover is a separate matter. The agreement should define that line before the inspection, not during it.

Good records make the conversation shorter. Photos with measurements, dated test logs and a signed handover form give both parties the same facts to discuss, and they keep the discussion on the unit rather than on memory.
