There isn’t enough accessible evidence to name a defensible 2024 winner among cordless lawn mowers. The safest way to choose is to match deck width, battery capacity, drive type and cut options to your lawn, then compare models using independent test results where available. EGO’s LM2135SP is a useful example of the specifications to check, but its manufacturer runtime claim is not an independent performance ranking.
How to compare cordless lawn mowers
Start with your lawn and the work you need the mower to do. A wider deck covers more ground per pass; self-propelled drive can reduce pushing effort on slopes or during longer sessions. Those features also need to be weighed against the mower’s kit price, weight, battery capacity and storage requirements. There is no universal best configuration for every yard.
- Lawn size and terrain: Consider the area you mow and whether slopes or long sessions make powered drive especially useful.
- Deck width: A wider deck can cover more ground per pass. Compare widths alongside storage and handling needs.
- Battery and runtime: Check the battery capacity and number of batteries included in the exact kit. Runtime varies with battery size and operating conditions, so treat a runtime figure as meaningful only with its battery and source attached.
- Drive: Confirm whether the mower is push or self-propelled, and decide whether the added assistance is worth the associated kit weight and cost.
- Clipping options: Check whether the mower supports mulching, bagging and side discharge if you need those choices.
- Ownership details: Compare warranty terms, weight, storage, and compatibility with batteries or tools you already own. Confirm the exact voltage and platform rather than assuming batteries interchange.
Consumer Reports’ rating table includes deck size, battery voltage, drive wheels, warranty and runtime among its comparison criteria. Its indexed recent-testing summary gives an average runtime of 45 to 50 minutes per charge for battery walk-behind mowers; that across-model average does not predict how long a particular mower will run. Consumer Reports lawn mower ratings are useful as a reminder to compare models across several attributes rather than treating one specification as decisive.
What the available model examples establish
EGO POWER+ LM2135SP
EGO describes the LM2135SP as a 21-inch, self-propelled Select Cut mower with mulching, bagging and side-discharge modes. The company says it is compatible with EGO 56V ARC Lithium batteries and claims up to 60 minutes of runtime when used with its recommended 7.5Ah battery. That is a manufacturer maximum claim, not an independently tested result; actual runtime depends on operating conditions. EGO lists a five-year limited tool warranty and a three-year limited battery warranty on its product page. Check the exact kit before buying, because battery inclusion depends on configuration.

Consumer Reports’ indexed battery push mower listing includes the EGO LM2135, but the accessible information does not establish a 2024 rank or test score for the LM2135SP. Do not treat the product specifications as proof that it was the top-performing mower that year. Consumer Reports mower listings
Greenworks 80V, 21-inch mower
Greenworks’ official listing describes an 80V, 21-inch, 3-in-1 self-propelled cordless mower supplied with a 4.0Ah battery and charger. That makes it a comparison candidate, not a demonstrated winner or a direct performance equivalent to the EGO model. Compare the exact kit contents, battery platform, drive and cutting modes, and seek comparable independent testing before drawing a performance conclusion. Greenworks 80V mower listing
Rank #2

Why this cannot be a reliable 2024 winners list
The accessible evidence does not establish original 2024 independent test scores, a historical ranking, or comparable prices for these models. Consumer Reports’ current indexed buyer-guide and best-of material is dated 2026, while its cited 2024 guide PDF was inaccessible. Its pages also could not be directly accessed for fuller detail. The available information supports a practical comparison framework and model examples, but not a claim that one mower was definitively the best in 2024.
That date distinction matters: a 2024 recommendation is historical, not automatically a recommendation for a current purchase. Model availability, included batteries, prices and warranty terms can change, so verify the manufacturer’s current listing and the exact retailer kit before ordering. Consumer Reports says its broader lawn-mower and tractor reliability and satisfaction inputs draw on member survey data gathered in fall 2022, 2023 and 2024, covering more than 46,000 lawn mowers and tractors purchased between 2014 and 2024. That sample context is not a battery-mower statistic or a model-specific test result. Consumer Reports lawn mower buying guide

A practical selection checklist
- Measure the job: Estimate the area to mow and note slopes, obstacles and storage constraints.
- Choose a deck and drive: Compare deck widths, then decide whether push or self-propelled drive fits the terrain and effort you are willing to supply.
- Verify the battery kit: Check the included battery capacity and count, charger, and compatibility with any battery platform you already own.
- Read runtime claims precisely: Record which battery a figure assumes and whether it is a manufacturer claim or an independent test. Do not apply an across-model average to an individual mower.
- Check cut handling and ownership terms: Confirm mulching, bagging and discharge options, plus current warranty terms and storage requirements.
- Compare evidence before ranking: Use comparable independent results where available. If scores or test conditions are not established, treat specifications as specifications rather than proof of superiority.
