8 Best Cordless Lawn Mowers for Mulching in 2026

This dual-battery powerhouse redefines value in the cordless lawn mower space by delivering extended runtime without sacrificing performance. At the heart of its design is an upgraded brushless motor that operates 40% more efficiently than traditional brushed models, translating to quieter, cooler, and longer-lasting operation—ideal for homeowners tired of gas fumes and engine maintenance. The 17-inch cutting deck ensures solid coverage per pass, while the 6 adjustable cutting heights let you tailor your mow from a close 0.98 inches to a lush 2.95 inches, making it perfect for varied grass types and seasonal changes.

In real-world testing, the mower handles moderate to dense grass with confidence, especially when both 20V batteries are engaged. However, in taller or wet grass, the motor occasionally slows, indicating its sweet spot lies in regular maintenance mowing rather than overgrown lawn recovery. With a 30-pound frame, it’s easy to push and maneuver around flower beds and trees, and the 11-gallon rear bag is sufficient for small to medium yards—though you’ll likely need to stop and empty it halfway through larger properties. Mulching performance is clean and consistent, leaving behind finely chopped clippings that decompose quickly to nourish the soil.

Compared to lighter models like the Grelawner 40V, the Litheli trades a bit of agility for broader cutting capacity and dual-battery convenience. It doesn’t match the premium feel of the EGO POWER+ or the expansive reach of the PowerSmart 21-inch model, but it delivers where it counts: reliable mulching, solid runtime, and excellent value. For budget-conscious buyers who want two batteries out of the box, this mower stands as a compelling middle ground between affordability and functionality—offering more cutting width and runtime than entry-level 16-inch models without the premium price tag.

Meet the featherweight champ of everyday mowing—the Grelawner 40V cordless mower is engineered for effortless handling and smart performance in small to medium lawns. Weighing just 25.13 pounds, it’s one of the lightest models in its class, making it a top pick for users who prioritize ease of movement and storage. Its 40V brushless motor isn’t just energy-efficient—it automatically adjusts power output based on grass density, delivering extra torque when needed and conserving battery in thinner patches, which extends usable runtime and reduces strain on the motor.

During testing, the mower excelled in routine weekly maintenance, cleanly cutting dry, short-to-medium grass with minimal resistance. The 16-inch cutting deck covers ground efficiently, and the 14.5-gallon bag is one of the largest in this size category, reducing emptying frequency. The bag-fill indicator is a thoughtful touch, helping prevent messy overflows. While mulching is effective in dry conditions, wet grass tends to clog the chamber more easily than on wider-deck models. With up to 30 minutes of runtime, it comfortably handles yards up to 2,300 sq ft—perfect for suburban lawns—but may fall short for larger properties without a spare battery.

When compared to the KOMASTY or Litheli models, the Grelawner stands out for its ultra-lightweight design and intelligent power management, though it sacrifices some deck width and raw power. It’s less suited for heavy-duty mowing than the PowerSmart or EGO models but shines as a low-maintenance, easy-to-store solution for average-sized yards. For homeowners who want a nimble, responsive mower that adapts to lawn conditions, this model offers superior ergonomics and smarter efficiency than similarly priced rivals—making it a standout for comfort-focused users.

If mulching performance is your top priority, the STEELITE 40V mower steps up with a high-efficiency brushless motor spinning at 3400 RPM, delivering crisp, clean cuts that turn clippings into fine, fast-decomposing mulch. This 17-inch deck mower is purpose-built for nutrient-rich lawn care, with a dedicated mulch plug that seamlessly redirects clippings back into the turf without clogging—thanks to optimized airflow and blade design. The 6-level height adjustment is smooth and intuitive, allowing quick changes from 0.98 to 2.95 inches, so you can adapt to seasonal growth or grass type with precision.

In real-world use, the mower maintains strong momentum through dry, medium-height grass, and the dual 20V 4.0Ah batteries provide up to 25 minutes of continuous runtime—enough for most small to mid-sized yards. However, in thick or damp grass, the motor shows signs of strain, and performance dips slightly compared to higher-voltage models like the Greenworks 60V or EGO POWER+. The 40L (10.6 gal) collection bag is spacious for its class, but not as large as the PowerSmart or Grelawner options. At 30 lbs, it’s easy to push and turns tightly, though the folding handle isn’t as compact as some competitors.

Positioned between budget models and premium brands, the STEELITE delivers best-in-class mulching capability at a competitive spec level. It outperforms the KOMASTY and WORX in cutting consistency and runtime while offering the same dual-battery convenience as the Litheli—but with a more refined motor system. For users focused on eco-friendly lawn feeding and consistent cut quality, this mower offers superior mulching precision and durability, making it a smarter long-term investment than basic entry-level models.

Don’t let its compact 15-inch deck fool you—the KOMASTY 40V mower packs a budget-friendly punch with features typically found in pricier models. Equipped with a 3400 RPM brushless motor and dual 4.0Ah batteries, it delivers strong, consistent cutting power for its size, slicing through thick patches with surprising ease. What sets it apart is the inclusion of two chargers, allowing simultaneous battery recharge—eliminating downtime and maximizing efficiency, a rare perk at this price point. The dual-action safety switch adds peace of mind, preventing accidental starts.

In testing, the mower proved reliable for small yards and narrow spaces, where its lightweight build and tight turning radius shine. The 5-position height adjustment (1.37″ to 2.95″) handles most grass conditions, and switching between mulching and bagging is tool-free and quick. The 10.6-gallon bag is adequate but fills faster on longer mows, requiring mid-session emptying on larger lawns. While it manages dry grass well, wet or overgrown turf can overwhelm the deck, and the smaller cutting width means more passes than wider models.

Compared to the WORX or Grelawner, the KOMASTY offers better battery value and faster recharge capability, though it lacks their refined ergonomics or smart motor tech. It’s not built for large lawns like the PowerSmart, but for urban yards or second homes, it’s a no-frills, high-value workhorse. For buyers seeking maximum features per dollar, this mower delivers exceptional bang for the buck—outfitting you with dual batteries, dual chargers, and solid mulching performance without breaking the bank.

Designed for tight spaces and petite lawns, the WORX WG779 is a compact precision tool that excels where larger mowers struggle. Its 14-inch deck slips effortlessly through narrow garden gates and tight corners, while the 6-position height adjustment (1.5″ to 3.5″) gives fine control over cut height—ideal for manicured lawns or delicate grass types. The Intellicut technology is a standout: a patented sensor system that automatically adjusts blade speed based on grass density, maintaining smooth operation and conserving battery in lighter areas.

In real-world use, the mower is exceptionally quiet at 87.8 decibels, making early morning or weekend mowing neighbor-friendly. The two 20V 4.0Ah batteries offer enough juice for up to 1/8 acre, perfect for townhouses or small suburban plots. Mulching is clean and consistent, and the 0.85-bushel bag is compact but functional. The fully collapsible handle makes storage a breeze, fitting neatly in closets or garages. However, the small deck means more passes for even modest yards, and battery life can be strained in thick grass.

When stacked against the Grelawner or KOMASTY, the WORX is less about power and more about smart design and space efficiency. It doesn’t match their runtime or deck size, but it wins in storage convenience and intelligent cutting tech. For apartment dwellers, patio homeowners, or those with ultra-small yards, this mower offers precision, quiet operation, and seamless integration with the WORX PowerShare ecosystem—making it the most practical and expandable choice for minimalist lawn care.

Step into the next tier of cordless mowing with the Greenworks 60V, a high-voltage performer that delivers 40 minutes of runtime on a single charge—among the longest in this lineup. Its 60V brushless motor generates serious torque, effortlessly powering through thick, dry grass with a level of consistency that rivals gas mowers. The 17-inch rust-resistant steel deck is built for durability, and the 6-position height adjustment (1.5″ to 3.15″) ensures you can fine-tune your cut for optimal lawn health.

In testing, the mower maintained strong performance across varied terrain, including slight inclines and patchy grass, with minimal motor lag. The 40-minute runtime comfortably covers up to 1/3 acre, making it suitable for medium to large yards—especially when paired with an extra battery. Mulching is excellent, producing fine clippings that blend smoothly into the turf. The lightweight frame makes it easy to maneuver, though the handle could be more ergonomic for taller users. Recharge time is just 90 minutes, faster than many competitors.

Against the EGO POWER+ or PowerSmart, the Greenworks lacks self-propel or side-discharge, but it wins in ecosystem value and runtime efficiency. It’s not as feature-rich as the EGO, but it offers longer battery life than the STEELITE or Litheli and integrates seamlessly with 75+ Greenworks 60V tools. For users building a unified cordless yard system, this mower delivers exceptional battery synergy and cutting endurance, making it the smartest long-term investment for eco-conscious homeowners.

This is the undisputed king of cordless mowers—the EGO POWER+ LM2135SP combines 56V ARC Lithium technology, self-propelled Touch Drive, and a premium Select Cut blade system to deliver a cut quality that genuinely rivals gas-powered models. With 60 minutes of runtime on a single 7.5Ah battery and a 7-position height adjustment (1.5″ to 4″), it’s built for large, demanding lawns. The Touch Drive system puts speed control in your palm, allowing smooth acceleration and effortless hill climbing without straining your arms.

In real-world trials, the mower glided through tall, dry grass with zero bogging, thanks to its high-efficiency brushless motor and advanced blade design. The 3-in-1 functionality (mulching, bagging, side discharge) offers unmatched versatility, and the bright LED headlights make evening mowing safe and practical. The rapid charger replenishes the battery in just 60 minutes, minimizing downtime. It’s heavier than push models, but the self-propel feature eliminates the effort.

Compared to the Greenworks or PowerSmart, the EGO stands above with self-propel, longer runtime, and superior cutting tech. It costs more than the Litheli or KOMASTY, but delivers professional-grade performance in a residential package. For homeowners with large or hilly yards who demand effortless operation, extended runtime, and best-in-class mulching, this mower is the ultimate all-around performer—offering more power, features, and refinement than any other model here.

Built for large-yard domination, the PowerSmart 40V mower boasts an industry-leading 21-inch cutting deck—25% wider than most cordless models—letting you mow faster with fewer passes. This dual-battery beast comes with everything you need: two 40V 4.0Ah batteries and a charger, ensuring non-stop mowing across half-acre properties. The 3-in-1 function (mulching, bagging, side discharge) gives maximum flexibility, whether you’re feeding your lawn or clearing debris quickly.

In testing, the mower powered through thick, dry grass with impressive stability, though it showed slight hesitation in wet conditions. The 6-position height lever (1.5″ to 3.9″) makes it adaptable to all growth stages, and the fold-flat design saves up to 70% storage space—perfect for garages or sheds. The nationwide service network of 3,000+ repair centers adds rare peace of mind for a budget-conscious brand. While not as refined as the EGO, it covers ground faster than any other model here.

Against the Greenworks or STEELITE, the PowerSmart wins on deck width and storage efficiency, though it lacks their voltage or ecosystem depth. It’s heavier and less agile than smaller models, but for large-yard owners who value speed and convenience, it’s unmatched. With best-in-class cutting width and foldable design, this mower delivers maximum coverage and practicality—making it the top pick for spacious properties where time and space matter most.
