The hidden costs of robots: integration, downtime, maintenance, staff time, and the floor that has to be flat

The robot is often the smallest line on the bill. Where the rest of the money goes, with published numbers, and a simple worksheet to get to a real total cost before you sign.

The short version

  • In industrial automation the robot itself is often a quarter of the total system cost. BCG found exactly that for spot-welding cells, and said the peripheral equipment typically costs more than the robots (BCG).
  • The usual surprises: site preparation (floors, Wi-Fi, power), integration with your systems, people time, downtime, consumables like batteries, and mobilisation for services.
  • Robots are fussy about floors. One common warehouse robot spec allows gaps of up to 29 mm and steps of up to 10 mm, and wants no water, oil or dirt (MiR600 specifications).
  • Use the worksheet at the end. If a supplier won't help you fill it in, that tells you something.

Every robot brochure has a price. Very few have a total. Here's what sits under the waterline.

All prices as published, accessed October 2026, from Whirrwork's price data. Not every row is like-for-like, and that's the point: the robot and the working system are different purchases.

1. The floor that has to be flat

Wheeled robots are picky. The MiR600 specification lists a maximum traversable gap of 29 mm and a maximum step of 10 mm (and steps aren't recommended at maximum payload), and the floor must have no water, oil or dirt (MiR600 specifications). Locus lists "smooth floors" among the customer's site responsibilities (Locus).

What that means in a real building: expansion joints, dock plates, drain covers, cracked slabs, a ramp nobody thinks of as a ramp, and the patch of floor near the loading door that's always a bit wet. Each one is either a repair, a route change or a robot that stops.

What to do: walk every intended route with the supplier and a tape measure before you sign. Ask for the written floor spec. Get the repair list priced.

2. The network nobody budgeted for

Mobile robots live on Wi-Fi. The MiR600 spec includes Wi-Fi coverage heatmaps among its diagnostics, which tells you how much it matters (MiR600 specifications). Locus asks customers for a dedicated internet line. Outdoor robots and drones may need cellular coverage or a base station.

What to do: ask for a coverage survey and the minimum network requirements, then ask your IT team what it costs. Also ask IT how long their security review takes, because that's often the real schedule.

3. Power and charging

Robots need chargers, chargers need power, and power in the right place may need an electrician. Locus lists "power feeds to charging stations" as a customer responsibility. Security robots and drones also need charging time: our security robot guide notes the Knightscope K5 brochure lists about 2.5–3 hours of patrol between charges.

What to do: count chargers, locate them on the floor plan, and get the electrical work quoted.

4. People time

This is the cost most often set to zero in business cases. It shouldn't be.

  • Training. Operators, supervisors, maintenance staff.
  • Babysitting. Someone has to clear jams, rescue a stuck robot, pick up the cables the floor scrubber can't avoid.
  • New skills. Amazon says its newest robotics-heavy fulfillment centre needs 30% more people in reliability, maintenance and engineering roles (Amazon). That's a company claim, but the direction is plausible: robots add skilled jobs you have to staff or buy.
  • Consumables, done by your staff. Locus customers are expected to provide trained technicians to install replacement wheels, casters and batteries that Locus supplies.

What to do: estimate hours per week for supervision and first-line fixes, and price them at your real loaded labour rate.

5. Downtime

When a robot stops, the work it was doing stops too, and the backup plan is usually "the humans we no longer have". Siemens estimates the world's largest companies lose about $1.4 trillion a year, or 11% of revenue, to unplanned downtime across industrial operations generally (Siemens, 2024). That's not a robot-specific number, but it's a reminder that "the machine is down" is rarely cheap.

What to do: decide your manual fallback before go-live. Ask the supplier for mean time to repair, spare-parts location and on-site response times, and put them in the contract (see RaaS red flags).

6. Batteries and other things that wear out

Batteries are consumables with a robot attached. The University of Missouri's spray-drone analysis assumes batteries last 1,000 charge cycles or five years, and its one-drone farm setup costs $56,000 in total, including a $23,000 drone package, three batteries, a generator, trailer and tank system (MU Extension G1274). The drone itself is well under half of that.

What to do: ask for battery cycle life, replacement price, and who pays when capacity fades.

7. Mobilisation, weather and the report (for services)

If you hire a robot service rather than buy, the hidden costs move into the quote:

  • Mobilisation: someone has to bring the robot and set it up. On small jobs that can be most of the bill.
  • Weather days: drones don't fly in high wind. Who pays when the crew arrives and can't fly?
  • The report: 400 photos isn't an answer. Make sure the deliverable is the finding, not the files.

We cover these in Do you need a robot, or a guy with a ladder?.

8. The pace problem

Sometimes the hidden cost lands on people's bodies. Reveal's 2020 investigation reported that serious injury rates at Amazon's robotic warehouses were more than 50% higher than at its non-robotic ones from 2016 to 2019, linked to faster pick rates (The Verge). Injuries cost money, morale and staff. Budget for ergonomics, not just robots. More in robots and jobs.

Worked example: when does owning a spray drone beat hiring?

The MU Extension analysis is a model of how to do this honestly (MU Extension G1274):

  • Custom hire: about $16 per acre in Missouri.
  • Owning one drone at 1,000 acres a year: about $12.27 per acre, once batteries, generator, labour and depreciation are counted.
  • Break-even: about 980 acres a year. Below that, hiring is cheaper.

Two things to notice. First, the break-even includes everything, not just the aircraft. Second, national custom rates moved fast: the American Spray Drone Coalition's survey put the average US rate at $13 per acre in 2025, down from $21 (ASDC). Falling service prices push the break-even up. Check current spraying rates before you buy.

The total-cost worksheet

Fill this in for 36 months. If a line is "unknown", that's a question for the supplier.

LineYear 1Year 2Year 3
Robot or subscription
Implementation / integration / installation
Site work: floors, network, power, chargers
Peripherals: grippers, guarding, conveyors, docks
Training (hours × loaded rate)
Supervision and first-line fixes (hours × rate)
Maintenance contract and spares
Batteries and consumables
Insurance changes
Downtime fallback (manual cover)
Removal / end-of-term costs
Total

Then divide by the units you care about: per pick, per acre, per square foot, per hour of coverage you actually need.

Bot or Not?

The robot pencils out when…It probably doesn't when…
Floors, network and power are already goodThe building needs work before a robot can move
The job runs most hours of most daysUtilisation is low or seasonal
You have (or will hire) people to look after itNobody owns the robot after go-live
The supplier helps fill in the worksheetThe supplier only talks about the sticker price

And, as ever, the Ladder Test: if one competent person could do it safely in an afternoon, the cheapest robot is the one you don't buy.
