Counting Unfilled Night Hours Before a Robot Lease Quote

The short answer: count the gap, then price it

To total what unfilled overnight cleaning hours cost one site, list every night shift that opened short, time one full floor pass, and price the staff time that covered or failed to cover the gap. Multiply those inputs across a year and you have one figure that a finance lead can trace back to timecards and floor logs.

Set that figure beside a fixed lease quote from a site assessment. The quote is a known number. The gap is a number you build yourself, so the comparison holds only if the gap is counted with the same care as the quote.

Why the night gap is drawing attention now

According to the International Federation of Robotics (IFR), global professional service robot shipments rose 24% to almost 250,000 units in 2025. Transportation and logistics was the largest category, at about 47% of units. Hospitality ranked second and professional cleaning ranked third, with floor cleaning as the main cleaning use.

IFR's service robot figures come from a supplier survey, and IFR notes they are not projected to the whole industry. That makes them a read on direction, not a benchmark for your building. Your schedule and floor logs are the better source for a single site decision.

Step one: log every short night

Start with the schedule, not the payroll summary. Export the overnight roster for the past twelve months, mark each shift where the crew was short, and record the open hours as the gap between the planned crew and the people who clocked in. Include call outs, vacant positions and nights when a contractor cancelled.

A shift that ran two hours short is not the same as one with no cleaner at all. Record the hours actually missing, not the whole shift, or the total will overstate the gap.

Log at the shift level. A summary line saying the site was short some nights cannot be audited. A finance lead will ask which nights, how many hours, and who signed off.

Step two: turn open hours into missed floor passes

A floor pass is one complete run of the scheduled route, with the same zones, sequence and finish point. Walk that route once on a normal night with a stopwatch and record the minutes. A brochure figure or a rule of thumb will not hold up in a finance review, but a timed walk will.

Divide the open hours by the minutes per pass to see how many passes the crew could not run. Not every missed pass is a loss, since some zones can wait a night. Flag the ones a manager said could not wait, such as a spill zone, a dining room before opening or a lobby before a tour. The flagged count is the figure that matters most.

Step three: price the staff time

Use your payroll rates, not outside benchmarks. Count three kinds of staff time: hours a day shift employee spent re-cleaning or covering zones, overtime or premium pay that filled the gap, and supervisor minutes spent arranging coverage. Our research for this piece did not verify any wage figures, so the rates belong to your payroll records.

Keep the staff cost separate from the missed pass count. Adding them together hides which part of the gap is labor and which part is floor coverage, and a lease test needs to see both.

Where a fixed lease quote enters the comparison

With the gap totaled, the lease side becomes simpler. Service Robot Co. leases robots only, on a three year lease with lease financing, and quotes one fixed lease figure after a site assessment. Our team maps the floor and measures the routes before that quote is set, so the number you compare against comes from your building rather than a catalog.

We are OEM neutral. We choose the robot that fits your floor across manufacturers, then deploy, integrate and train your team. Place the quote beside the annual gap total, and then test the gap against fewer open nights, because a three year term should hold up under more than one scenario.

What the comparison can and cannot prove

The gap is a ceiling on what you could recover, not a forecast of every night. A robot runs scheduled floor routes. It does not replace every task a person handles, such as restroom resets after an incident, spill response that needs judgment, or guest questions. Count only the passes a robot could cover.

Check the edges of each number. If the quote leaves out deployment or service, the comparison is incomplete. If the gap includes nights covered by a manager working a double shift, the same hour may be counted twice. Finance will catch both, so catch them first.

How a finance lead checks the inputs

A finance lead should be able to follow each number back to a source. Three checks make that possible.

• Each open hour traces to a dated schedule line or timecard.
• Each floor pass time comes from a timed walk on a normal night, with the date noted.
• Each lease term in the quote matches the same period as the gap total.

What service coverage should be in writing

Service belongs in that review too. RoboCare, our service plan, covers every unit we lease, backed by regional service engineers in every state we service. A quote that does not state who answers when a unit stops overnight leaves a hole in the comparison.

Ask for those terms in writing with the quote, and ask how they apply to the nights already in your gap log.
