Robot Mower vs Crew Payback Calculator

Robotic mowing stopped being a consumer novelty during 2026, and the question reaching lawn and grounds operators changed with it: not is this any good, but does the machine pay for itself against what my crew costs me today. That is a capex question, and it has an answer with arithmetic in it. This tool costs your crew and a robot installation over the same season, differences them, and divides the upfront cost by whatever is left — then checks the result against how long you expect the machines to last.

Why every price box starts empty

There is no price table in this tool, and that is deliberate. Manufacturers publish specifications, not prices: Husqvarna’s US robotic mower range lists a lawn-size capacity for every model it sells, residential and commercial, and a price for none of them. Delivered price, installation, satellite or reference-station setup, and service contracts are quoted by dealer and by site. Specifications also date fast in a category that has been launching new models continuously through 2026, which is exactly why coverage and capacity are inputs here rather than a maintained table someone has to keep honest.

So the delivered price per machine, the one-off install, the annual service line and the subscription are all yours. What the tool supplies is the shape of the decision and the arithmetic that connects the pieces.

The assumption that makes every robot business case look good

A mower mows. It does not string-trim, edge, blow, pick up litter or empty its own clippings, and it needs blade changes, periodic checks and — in a cold-winter market — removal and storage out of season. Someone is still attending the property, and the truck is still driving there.

This is the single most common error in a robot business case, so the calculator is built around it. There are two visit blocks, not one: the crew you run today, and the crew that still turns up after the machines are installed. The second block defaults to the same visit count as the first, because what usually falls is the length of the visit rather than the number of them. Set the residual visits to zero and the tool tells you plainly what you have just assumed. The paid drive hours and the truck cost carry across both scenarios unchanged for the same reason: the property does not move closer.

If you have never separated the mowing minutes from the rest of the visit, the mowing time estimator is where to get the first number, and the production rate job time estimator is where to get the second.

De-rate the capacity before you count machines

Every machine count in this tool comes from area divided by capacity, rounded up. The capacity you should divide by is not the headline one. Husqvarna’s Automower 560 EPOS specification gives a lawn size of 1.5 acres and prints a ±20% tolerance against it — the manufacturer’s own statement that the acreage is the middle of a range, not a guarantee. Its April 2026 announcement of the same machine describes it as maintaining “up to 1.5 acres in a 24-hour period” for municipal and facility-managed grounds.

Slope, obstacles, narrow passages between zones, wet growth and a schedule that has to fit around people using the space all push effective coverage further down from there. So the de-rate field starts at that 20% and stays editable: set it to zero and you size off the rated figure, raise it and you size off a harsher reading of your own site. The machine count then rounds up, because you cannot buy part of a mower — which is why a 1.5-acre property and a 1.5-acre machine can still come out at two machines, and why the payback is often decided before you have entered a single price.

The labor number is yours, not a benchmark

Labor is almost always the line that decides this comparison, and it is the one place where a published average will mislead you. What belongs in the box is your loaded cost per crew hour: the wage plus payroll taxes, workers compensation, liability, and paid time that is not on a property. The labor burden rate calculator works that multiplier out from your own payroll, and the service hourly rate tool is the companion for the other direction — what you have to charge, rather than what an hour costs.

For an external reference point on the wage half only, the U.S. Bureau of Labor Statistics publishes average hourly earnings in landscaping services as CES series CEU6056173003: $28.01 in June 2026, a preliminary figure at the time of writing, against $26.96 in June 2025. That is a national series for one country and it is a wage, not a loaded cost — useful for sanity-checking, useless as an input. Type your payroll.

Why a pre-2026 comparison no longer holds

The crew scenario burns fuel and the robot scenario burns grid electricity, so the comparison moves whenever fuel does — and fuel has moved a long way. EIA’s weekly retail prices for the week ending 17 August 2026 put the US average for regular gasoline at $4.049 a gallon against $3.125 a year earlier, and on-highway diesel at $5.454 against $3.713: roughly 29 and 47 percent higher year over year. Any machine-cost-per-hour figure you worked out before that understates the crew side of this calculation.

That figure deserves rebuilding rather than reusing, and the equipment cost per hour calculator is where to rebuild it — depreciation, fuel and maintenance for the machine your crew actually runs, at today’s prices. Once the crew-side number is honest, the same fuel shift is worth carrying into what you charge, which is what the lawn care pricing calculator is for.

Check the payback against the machine’s life

A payback period on its own is easy to accept, because a number always looks like an answer. The question that matters is whether it lands before the machines wear out. Enter the service life you expect and the tool reports both: the payback in years and a verdict on whether it fits. A fifteen-year payback on a machine you plan to run for eight is not a slow win — it is a loss, and the net-over-life line puts a figure on it.

The other output worth reading is the crew hours freed per season. Those hours only turn into money if you have somewhere to put them: another property, a higher-margin service line, or a route that gets tighter rather than emptier. The rest of the lawn and landscape tool hub covers what to do with recovered capacity once you have it.

What this tool deliberately does not do

It does not recommend a machine, a brand or a navigation technology, and nothing here should be read as a test result — no equipment has been tested for this page. It is arithmetic on numbers you supply. Model reliability, warranty terms, theft exposure and the downtime that follows a fleet-wide fault are real risks a payback number cannot express, and 2026 put a dated, named example against two of them.

On 7 May 2026 the security researcher Andreas Makris reported vulnerabilities in Yarbo’s remote diagnostic, credential-management and data-handling systems. Yarbo confirmed the findings in its own security update, which states that it disabled the remote diagnostic tunnels, reset device root passwords and closed unauthenticated endpoints. That is the fleet-wide-fault risk in its literal form — a defect in the platform rather than in any one machine.

Separately, on 9 July 2026 the US Consumer Product Safety Commission published recall 26611, covering about 554,780 Kobalt 24V and 48V yard power tools built by Greenworks — trimmers, blowers, mowers, chainsaws and pruning saws — after 34 reports of batteries producing smoke, sparking or catching fire while charging through the USB-C port with the battery still in the tool. No injuries or property damage were reported. That recall is cordless handheld gear, not robotic mowers; it is here as the shape of the battery risk that travels with any electrified fleet, and it says nothing about robot mowers specifically.

Neither event carries a cost figure, so neither is quantified in the model above. The honest way to carry that risk into the model is to raise the residual visits or the annual service line, not to assume it away.

Nothing is stored and nothing is sent. Every figure stays in your browser, and the season is whichever one you work: the visit counts are yours to set, and the northern and southern hemisphere mowing seasons sit six months apart, so no month named anywhere on this page would be right for both.
