53 Robotic Lawn Mower Statistics: Market Scale, Turf Results, Costs, and Efficiency

by

Robotic lawn mower statistics span commercial sales, global market estimates, controlled turf trials, energy use, operating cost, obstacle detection, and mowing dimensions. The figures below separate company results and forecasts from measured trials, while keeping geography, dates, and test conditions explicit.

Market scale and commercial trendrnThe broad market numbers available here are estimates and forecasts rather than an official shipment census. A figure reproduced in the University of Florida IFAS guidance, attributed there to Arizton, valued the global robotic-mower market at USD 351.14 million in 2021 and forecast it to reach USD 704.55 million by 2027.

These values are commercial market research figures reproduced in extension guidance, not independently verified global sales totals.

(UF/IFAS, Autonomous or Robotic Mower Use on Florida Lawns)

Company reporting provides a separate view of commercial scale. Husqvarna Group reported SEK 8.1 billion in robotic-mower net sales in 2023, followed by SEK 7.2 billion in 2024.

Those are the company’s reported net sales, not the size of the entire worldwide category. In the same 2024 report, electrified products represented 44% of motorized-product sales, and the group reported 4.9 million connected devices.

(Husqvarna Group, Year-End Report January–December 2024)

The commercial indicators also have different denominators. Robotic-mower net sales are expressed in Swedish kronor and belong to Husqvarna Group; electrified products are a share of that group’s motorized-product sales; connected devices are a device count rather than a count of mower-owning households.

The 2021 and 2027 figures are global market values in U.S. dollars, with the latter explicitly labeled a forecast. Keeping those categories separate prevents a sales value, product mix percentage, device count, and market forecast from being mistaken for the same measure of adoption.

These measures describe different things: a market-research estimate describes a modeled global category, while Husqvarna’s figures describe one manufacturer’s reported sales and connected-device base. They should not be added together or treated as adoption rates.

The available evidence supports a market-scale picture, but it does not provide a residential ownership census.

Turf quality and mowing outcomes

A peer-reviewed 32-week tall-fescue trial in Pisa, Italy compared autonomous mowing with a weekly gasoline rotary mower. Results were recorded in weeks after treatment began, abbreviated WAT, and turf-quality and mowing-quality scores used a 1–9 scale.

(Autonomous Mower vs. Rotary Mower: Effects on Turf Quality and Weed Control in Tall Fescue Lawn)

Measurement point Autonomous mower Rotary mower
Turf quality at 8 WAT 5.8 5.5
Mowing quality at 8 WAT 7.6 6.9
Turf quality at 16 WAT 6.6 6.5
Mowing quality at 16 WAT 7.3 6.7
Turf quality at 24 WAT 6.9 6.4
Mowing quality at 24 WAT 6.9 5.8
Turf quality at 32 WAT 6.6 6.3
Mowing quality at 32 WAT 7.2 6.2

The trial’s structural measurements at 32 WAT also differed. Autonomous-mown tall fescue had a leaf width of 0.16 cm, compared with 0.23 cm for rotary-mown plots.

Shoot density was 3.6 shoots per cm² under autonomous mowing and 2.2 shoots per cm² under rotary mowing.

Read as a sequence, the quality scores show that the advantage was not identical at every observation. At 8 WAT, the turf-quality scores were 5.8 and 5.5, while the mowing-quality scores were 7.6 and 6.9.

At 16 WAT, turf quality was 6.6 versus 6.5 and mowing quality was 7.3 versus 6.7. At 24 WAT, the corresponding pairs were 6.9 versus 6.4 and 6.9 versus 5.8.

At 32 WAT, they were 6.6 versus 6.3 and 7.2 versus 6.2. The consistent unit and 1–9 scale make the comparison readable, but the single Pisa location and tall-fescue population limit its scope.

Fertilization was another measured factor in the same trial. At 32 WAT, unfertilized tall fescue had a turf-quality score of 5.4 and 2.6 shoots per cm².

The treatment receiving 150 kg ha⁻¹ nitrogen had a turf-quality score of 7.4 and 3.2 shoots per cm². These results show why mower comparisons should be read alongside grass type and management conditions; the study does not establish a universal score for every lawn.

Weed pressure and plant communities

The Pisa study also measured spontaneous weed cover and four transplanted weed species. At 16 WAT, spontaneous weed cover under autonomous mowing was 11.1%.

At 32 WAT, spontaneous weed cover under rotary mowing was 7.9%. Because these values come from different treatment conditions and measurement points, they are not a direct same-date comparison.

At 32 WAT, maximum weed diameter varied by species and mower treatment:

  • Bellis perennis: 6.6 cm under autonomous mowing and 4.3 cm under rotary mowing.
  • Trifolium repens: 24.0 cm under autonomous mowing and 7.0 cm under rotary mowing.
  • Trifolium subterraneum: 7.3 cm under autonomous mowing and 4.8 cm under rotary mowing.
  • Lotus corniculatus: 14.2 cm under autonomous mowing and 8.3 cm under rotary mowing.

The weed findings are treatment-specific measurements from transplanted-weed plots and a controlled tall-fescue experiment. They should not be interpreted as a general claim that robotic mowing increases or decreases weeds on all lawns.

Lawn species, mowing schedule, climate, and plot conditions can change the observed plant community.

The species-level values also show why an overall weed percentage is not enough to describe plant-community outcomes. The reported maximum diameters range from 4.3 cm for rotary-mown Bellis perennis to 24.0 cm for autonomously mown Trifolium repens.

Those are maximum diameters at the end of the stated trial period, not counts of plants, biomass, or a direct estimate of weed-control effectiveness across ordinary residential lawns.

Energy, time, cost, and labor

The Pisa study modeled a 702 m² tall-fescue area maintained at a 3.0 cm mowing height. The autonomous mower was scheduled for 8.00 hours per day, including mowing and recharging, with 5.30 hours per day of mowing time excluding recharging.

Its weekly electric-energy consumption was 1.37 kWh, while weekly primary-energy consumption was 2.98 kWh. The reported autonomous-mower weekly cost was EUR 14.37.

The rotary comparison required 0.63 hours per week, used 0.50 liters of gasoline per week, and had weekly primary-energy consumption of 4.64 kWh. Its weekly operating cost, including labor, was EUR 20.23.

These costs include the study’s stated Italian labor-cost assumption and describe the specified trial scenario, not a universal household price.

The electrical components were also quantified. The autonomous mower’s cutting-disc power requirement was approximately 30 W.

The boundary wire consumed 96 Wh per day and was operative for 24 hours per day. These figures help distinguish cutting energy from infrastructure or standby-related operation.

The time figures illustrate a basic difference in operating structure: the autonomous system occupies the lawn for much longer each day but divides that time between mowing and recharging, whereas the rotary comparison concentrates mowing into a shorter weekly session. The reported energy and cost figures should therefore be compared with their exact area, grass, mowing-height, schedule, and labor assumptions.

The energy measures are not interchangeable. Electric-energy consumption is reported as 1.37 kWh per week, primary energy as 2.98 kWh per week for the autonomous system, and primary energy as 4.64 kWh per week for the rotary system.

The rotary result additionally includes a measured 0.50 liters of gasoline per week, while the autonomous result includes the boundary-wire demand of 96 Wh per day. These distinctions matter when readers compare direct electricity use, upstream energy, fuel volume, and labor-inclusive cost.

An Auburn University institutional thesis experiment in 2025 tested commercial autonomous mowers. In that experiment, 1.23 mL of gasoline corresponded to 1 Wh of battery energy.

This is a test-specific energy equivalence, not a general conversion for every mower or fuel system.

(Auburn University, Cutting Edge Technologies: Assessing ROI and Safety of Autonomous Mowers)

On free plots, the autonomous mowers averaged 33.7 minutes per acre. The tested stereo-RGB-camera mower recorded an obstacle-detection probability of 93.8%, while the tested radar mower recorded 61.8%.

The experiment had limited tested obstacles and approach angles, so the probabilities describe those test conditions rather than a complete safety rate for residential yards.

The Auburn results complement, but do not replace, the Pisa operating scenario. The Auburn evidence concerns commercial autonomous mowers and free-plot cutting time; the Pisa evidence concerns a 702 m² tall-fescue area, a 3.0 cm height, energy use, cost, and turf outcomes.

Neither source provides a residential adoption percentage or a population-wide reliability estimate.

Operating dimensions and grass-height context

The UF/IFAS Florida guidance places robotic mowing in a specific lawn-management context. It describes robotic-mower cutting blades as smaller than 1.5 inches, compared with approximately 20 inches for the traditional-mower comparison.

The difference in cutting size helps explain why robotic systems are generally associated with repeated, lighter cuts rather than one large weekly cut, but the supplied figures do not establish a performance ranking by blade size alone.

Grass height is equally important when interpreting mower statistics. The same guidance says cool-season grasses are typically mowed below 2.5 inches.

For Florida lawns, St. Augustinegrass commonly requires a 2.5–4 inch mowing height.

Those ranges are guidance for the named grass and geography, not a universal setting for every lawn or climate.

(UF/IFAS, Autonomous or Robotic Mower Use on Florida Lawns)

Together, the measurements show why a single “robotic mower result” can be misleading. Market forecasts, manufacturer sales, turf scores, weed diameters, energy use, labor-inclusive costs, obstacle detection, and mowing-height guidance each answer a different question.

The most transferable comparisons are the ones that retain their population or plot definition, measurement period, geography, units, and stated limitations.
