Brushless Motor: Why It Matters for Everyday Mowing

The heart of this mower is its brushless motor, and that’s not just a fancy spec for the box. Brushless tech has real benefits when we’re pushing this thing across the lawn on a hot day.

In simple terms, a brushless motor is more efficient, wastes less energy as heat, and doesn’t wear down the way brushed motors do. That translates into longer life, steadier power delivery, and less noise and vibration for us while mowing.

Performance and Lifespan Benefits

We notice the difference in performance most when grass conditions get tougher—slightly taller grass, thicker patches, or slightly damp blades. A brushless motor tends to keep its torque more consistently, instead of bogging down or feeling like it’s straining.

Long term, we benefit from fewer motor-related issues and less likelihood of burning out the system with normal use. If we mow regularly and keep the lawn within reasonable length, the brushless design should help this unit stay in service for years.

Reduced Maintenance Compared to Gas or Brushed Motors

We’re not dealing with carbon brushes inside the motor that wear out over time. That means fewer internal components that need replacement. When we compare this to a gas mower—oil changes, spark plugs, air filters, fuel stabilizers—the WEN cordless design feels refreshingly simple.

Instead, we mainly focus on battery care, blade sharpening, and keeping debris out of the deck, which are all straightforward jobs most of us can handle without a trip to the repair shop.

2-in-1 Mower and Mulcher: Flexibility for Different Lawn Habits

We like that this mower doesn’t box us into just one mowing style. Sometimes we want clean bagging for a tidy look, and other times we’re happy to mulch and “feed” the lawn with clippings. This WEN model lets us do both.

Having the ability to switch between bagging and mulching means we can adjust our approach based on season, lawn health, and how often we mow.

Standard Mowing with Collection Bag

When we attach the 13-gallon collection bag, we get a neater, more polished appearance off the mower. That’s ideal if we’ve let the grass get a bit longer, or if we’re dealing with weeds that we’d rather not spread.

The bag size—13 gallons—is a decent compromise: large enough that we’re not stopping every few minutes, but not so big that it becomes heavy and cumbersome when we’re emptying it. For a quarter-acre lot, we should expect a few trips to the compost pile or yard waste bin, but it’s manageable.

Mulching Function with Plug

Mulching mode uses the included mulching plug, which blocks off the rear discharge and keeps clippings circulating under the deck for finer chopping. Once broken down, those tiny clippings fall into the grass canopy as natural fertilizer.

We find mulching especially helpful when we mow regularly and only take off a small amount at each pass. It improves soil health, reduces the need for synthetic fertilizer, and means fewer bags to haul to the curb or dump.

---

Cutting Width and Deck Design

With its 19-inch deck and 17-inch cutting blade, this mower strikes a balance between coverage and maneuverability. We’re not dealing with a little 14-inch trimmer-style unit, but it’s also not a heavy, full-size gas machine meant for half-acre or larger properties.

That 19-inch deck gives us a decent swath with each pass, helping us finish a quarter-acre lawn in a reasonable time while still being nimble around trees, flower beds, and landscaping.

Why the 19-Inch Deck Works for a 1/4-Acre Yard

For lawns up to around 10,300 square feet, which is roughly 1/4 acre, a deck size in the 18–20 inch range is very reasonable. It means we’re not stuck making an endless number of passes, but we still retain good control and steering in tighter spaces.

We should expect to spend less time mowing compared to smaller cordless units, especially if our yard has longer, straight stretches. The deck width is large enough to feel efficient but small enough to store in a standard garage without dominating the space.

Cut Quality and Blade Performance

Cut quality depends on blade sharpness, motor power, and deck design. With the brushless motor and a 17-inch cutting blade, this WEN mower aims to provide a clean, even cut. When the blade is properly sharpened and the grass isn’t excessively tall, we can achieve a neat, uniform finish.

If we keep up with regular blade maintenance—sharpening at least once or twice a season, depending on use—our lawn’s appearance will benefit. For thicker or tougher grass types, making sure the blade stays sharp becomes even more important, especially in mulching mode where recutting clippings demands more from the system.

---

Adjustable Cutting Heights: 1.5 to 3.2 Inches

We appreciate that this mower includes five quick-adjust height settings, ranging from 1.5 to 3.2 inches. That lets us tailor the cut height to our grass type, season, and local climate.

It’s a nice, practical range for typical residential lawns. We’re not going extremely low like a golf green, but we’re also not forced into an overly shaggy cut.

Matching Height Settings to Our Grass and Season

Many cool-season grasses, like fescue and bluegrass, tend to do well around 2.5–3 inches during peak growing seasons. Warmer-season varieties might tolerate slightly lower heights. With options from 1.5 to 3.2 inches, we can test what looks and performs best for our own lawn.

In hotter or drier months, keeping the height near the upper end (around 3 inches) can help shade the soil, reduce water loss, and protect roots. In cooler periods, we might trim a bit lower if we prefer a tidier, more manicured look.

Ease of Adjustment While Working

Quick-adjust height controls are something we often don’t think about until we’re on the lawn struggling with stiff levers or multiple wheels. The WEN’s five settings make it fast to switch heights when we move between shaded and sunny areas, or between thick and thin patches of grass.

We can change the height before each mow based on current conditions instead of just leaving it at one setting all season. That flexibility helps us keep the lawn healthier and better-looking overall.

Battery System and Runtime: Two 5Ah Batteries Included

The battery system is the backbone of any cordless mower. Here, WEN includes two 20V Max 5.0Ah lithium-ion batteries plus a dual port charger. That’s a generous setup that helps this model stand out among budget-friendly cordless options.

Each battery also has an onboard LED charge gauge, so we’re not guessing how much juice we have left while we work. That alone can save us some frustration when planning a mowing session.

Realistic Coverage: Up to 10,300 Square Feet on a Charge

WEN rates this mower to cut lawns up to 10,300 square feet—about 1/4 acre—on a single charge using both included 5Ah batteries. They estimate runtime at about 30 to 68 minutes, depending on lawn conditions and cutting height.

That range sounds broad, but it reflects the realities of mowing: tall, wet, or thick grass drains batteries faster; shorter, drier grass at a higher cutting height consumes less power. If we mow regularly and avoid letting the grass get out of control, we’ll lean toward the longer end of the runtime estimate.

Consistent Power at Any Charge Level

One of the quiet advantages of modern lithium-ion packs is consistent output across most of the charge. Instead of feeling a slow fade in power as the battery drains, we typically get steady performance until we’re close to empty.

That means we can keep pushing the mower with confidence—no need to constantly listen for bogging and wonder whether it’s time to stop. The power stays usable almost to the end, and when it’s done, we just swap packs and keep going if needed.

---

Compatibility with the WEN 20V Max Tool Series

We always like when a battery system isn’t limited to one product. With this mower, the two included 5Ah batteries can also power any tools in the WEN 20V Max cordless lineup.

If we already own WEN 20V Max tools, this mower slots naturally into our setup. If not, it opens the door to building out a cordless collection over time using the same batteries and charger.

Expanding Our Cordless Yard and Workshop Setup

Using one battery platform across multiple tools simplifies charging, storage, and budgeting. Instead of buying separate batteries and chargers for a string trimmer, hedge trimmer, drill, or blower, we can share packs between them.

For example, we might mow the lawn, then use the same batteries to blow off the driveway or trim edges. This kind of flexibility helps us get more value from every battery we own and keeps our tool collection more streamlined.

---

Dual Port Charger: Less Waiting, More Mowing

The included 20V Max dual port charger is an underrated convenience. We can charge both 5Ah batteries at the same time, which shortens the turnaround between mowing sessions.

Instead of juggling multiple chargers or plugging and unplugging packs throughout the day, we slot both batteries in and let the system handle it. That’s especially helpful if we tend to mow later in the day and want both packs ready for a quick cleanup or trimming job afterward.

Charging Strategy for Regular Use

If we have a typical weekly mowing schedule, we can build a routine that keeps our batteries healthy and ready. We might mow, then charge both packs the same day, and store them off the charger once they’re full.

Lithium-ion batteries appreciate moderate temperatures and not being left deeply discharged for long periods. By recharging soon after use and avoiding extreme heat or cold storage, we support long-term performance and lifespan.

Ease of Use: Storage, Handling, and Noise Level

Comfort and practicality matter just as much as raw power. With its collapsible handle and upright storage capability, this mower is clearly designed for garages and sheds where space is tight.

We also gain the typical cordless advantage: no cord to manage, no gas to spill, and significantly less noise than a traditional gas mower.

Collapsible Handle and Upright Storage

Being able to fold down the handle and store the mower vertically is a major plus if we’re working with limited space. Instead of dedicating a big floor footprint, we can keep it against a wall or in a corner.

We also find that a collapsible handle makes transport easier—whether we’re moving it between front and back yards or loading it into a vehicle if we ever need to take it somewhere else.

Quieter Operation for Neighborhood-Friendly Mowing

Electric mowers typically run quieter than gas models, and this WEN is no exception. That makes early morning or evening mowing sessions more neighbor-friendly. We’re less likely to disturb people relaxing indoors or outside.

Quieter operation also makes the whole process more pleasant for us. We can often work without feeling battered by engine noise, and we might even catch the sounds of birds or conversation while we cut.

---

Maintenance: Keeping Our WEN Mower in Good Shape

One of the main reasons we choose cordless over gas is to simplify maintenance. With this WEN model, our routine care checklist is pretty short and manageable.

We focus on cleaning, sharpening, storing correctly, and looking after the batteries. Following these basics goes a long way toward keeping performance strong and preventing avoidable issues.

Regular Cleaning and Blade Care

After mowing, it helps to brush or wipe off grass clippings, especially from the under-deck area and around moving parts. We want to avoid buildup that can hold moisture, cause rust, or interfere with airflow for mulching.

Blade sharpening is another key task. A dull blade tears grass blades instead of cutting cleanly, which can lead to brown tips and a less healthy lawn. Sharpening once or twice a season is usually enough for average use, but we might need more frequent touch-ups if we hit rocks or mow very often.

Battery Care Best Practices

For the two included 5Ah packs, there are some simple habits that extend life:

• Store them in a moderate temperature environment—not in a hot car trunk or freezing shed.
• Avoid completely draining them and leaving them empty for long periods.
• Charge after use and then remove from the charger once full, rather than leaving them on indefinitely.

By treating the batteries well, we help ensure we’re not buying replacements too soon and keep runtime strong year after year.

Realistic Limitations and Best-Fit Users

No mower is perfect for everyone. The WEN 20V Max 2-in-1 is clearly tailored toward a certain type of user and yard size. Knowing where it shines—and where it might not be the best choice—helps us decide if it fits our situation.

We should weigh our lawn size, grass thickness, mowing habits, and expectations around power and runtime before committing.

Ideal Lawn Size and Conditions

This mower is rated for lawns up to around 10,300 square feet, or roughly 1/4 acre. That suggests it’s best for:

• Typical suburban lots with manageable lawn areas
• Yards with mostly open space and moderate landscaping
• Grass that’s mowed regularly and not allowed to grow extremely tall

If we fall into that category, the included battery setup and 19-inch deck will likely serve us well. For much larger properties, we might either need additional batteries or a different class of mower.

Where It May Fall Short

There are some scenarios where this model might not be the strongest fit:

• Very large properties beyond 1/4 acre, especially if we want to finish in one continuous session without swapping or recharging batteries
• Extremely thick or rough lawns where heavy-duty, self-propelled gas units usually dominate
• Situations where we want ultra-low cutting heights below 1.5 inches

We can still use this mower in challenging situations, but we might have to slow down, mow more frequently, or accept that we’re using it in a role it wasn’t strictly designed to dominate.

Pros and Cons Summary

To keep our thoughts organized, it helps to step back and summarize what stands out on both the positive and negative sides. This perspective lets us weigh what matters most to us personally.

What We Really Appreciate

Some of the biggest strengths we notice are:

• Brushless motor for better efficiency, performance, and lifespan compared to brushed motors
• 2-in-1 functionality so we can switch between bagging and mulching easily
• Two 5Ah batteries included for solid runtime and immediate out-of-the-box usability
• Dual port charger that lets us charge both batteries simultaneously
• 19-inch deck that balances cutting coverage and maneuverability
• Five height settings (1.5–3.2 inches) for solid flexibility across seasons and grass types
• Collapsible handle and upright storage, which is great for small garages or sheds
• Compatibility with WEN 20V Max tools, adding value if we build or already have that ecosystem
• Quieter operation than gas, helping us keep the neighborhood peace

For many homeowners with modest lawns, these benefits combine into a very practical everyday mower.

What Might Give Us Pause

On the flip side, some potential downsides or tradeoffs include:

• Limited to about 1/4-acre in a single charge under typical conditions, which may not satisfy larger property owners
• Not self-propelled, so we’re pushing it manually (fine for flat yards, but more work on slopes)
• Battery performance depends heavily on grass conditions, requiring us to mow regularly for best runtime
• Cutting height range stops at 3.2 inches, which might be slightly short for people who prefer very tall cuts for drought resistance

Knowing these limitations helps set realistic expectations so we’re not disappointed later.

Using the Mower: A Typical Mowing Session

It can be helpful to walk through what a typical mowing session looks like with this model. That gives us a sense of the day-to-day experience beyond specs and numbers.

From prep to cleanup, the steps are straightforward, especially if we’ve dealt with gas or corded mowers in the past.

Before We Start

We’d usually:

1. Check that both 5Ah batteries are charged using the dual port charger.
2. Choose the cutting mode: bagging with the 13-gallon collection bag, or mulching with the plug installed.
3. Set the cutting height based on the season and grass length—maybe around 2.5–3 inches for a healthy, established lawn.

This prep takes only a few minutes, and we don’t have to worry about fuel, pull cords, or oil levels.

While We Mow

As we mow, we’ll notice:

• The brushless motor keeping a fairly steady tone as it works through average grass
• Easier maneuvering than heavier gas units, especially around landscaping and corners
• Less vibration and noise compared to a combustion engine, making the process a bit more relaxed

If we’re bagging, we’ll stop periodically to empty the 13-gallon bag. If we’re mulching, we’ll mainly keep an eye on any clumping in wet or extremely thick areas and adjust speed accordingly.

After the Job

Cleanup usually involves:

• Removing the bag (if used) and emptying clippings into compost or yard waste
• Brushing off grass from the deck, wheels, and handle
• Folding the handle down and setting the mower into its upright storage position

We can then return the batteries to the charger, and once they’re topped off, we’re ready for the next session.

---

Environmental and Lifestyle Considerations

Beyond pure performance, we might care about how our mower impacts our environment and daily routine. The WEN cordless design carries some natural advantages over gas that are worth acknowledging.

These benefits may not be the primary reason we buy it, but they do add to our overall satisfaction and peace of mind.

Reduced Emissions and Fumes

Electric mowers eliminate on-site exhaust, which means no gasoline fumes swirling around us while we work. That improves our immediate air quality and makes mowing more pleasant, especially if we’re sensitive to smell or pollution.

On a broader level, reducing dependence on small gas engines can contribute, in a modest way, to lower overall emissions—especially if our electricity comes from relatively clean sources.

Lower Noise and Better Neighborhood Harmony

We touched on noise earlier, but it’s worth repeating: a quieter mower affects more than just our ears. Early morning or evening mowing becomes less of a social gamble.

We’re less likely to wake a sleeping child, disturb someone working from home, or earn side-eye from neighbors trying to relax outdoors. That lower noise level is an everyday quality-of-life improvement.

Who Will Be Happiest with This Mower?

As we consider everything the WEN 20V Max 2-in-1 19-Inch Cordless Brushless Lawn Mower and Mulcher with Two 5Ah Batteries and Dual Port Charger (20839) offers, a clear picture forms of who it suits best.

We find it especially appealing for people who want cordless simplicity and dependable performance for a moderate-sized yard, without wading into overly heavy, expensive, or complex equipment.

Great Match For

We see this mower pairing particularly well with:

• Homeowners with lawns up to about 1/4 acre who mow weekly or on a regular schedule
• People moving away from gas mowers who want less noise, no fumes, and simpler upkeep
• Anyone interested in starting or expanding a WEN 20V Max cordless tool collection
• Households with limited storage space, where upright storage and a collapsible handle really help

In these scenarios, the mower’s strengths line up naturally with our day-to-day needs, and we benefit from the whole package: brushless motor, dual batteries, dual port charger, and flexible 2-in-1 cutting options.

Might Prefer Something Else If

On the other hand, we might want to look at different options if:

• Our yard significantly exceeds 1/4 acre and we expect to cut it all in one pass without battery swaps or additional packs
• We need a self-propelled unit due to steep slopes, mobility limits, or very dense turf
• We’re chasing ultra-low cutting heights that mimic sports turf or putting greens

In those cases, stepping up to a more powerful, possibly gas or higher-voltage electric, self-propelled model might serve us better.
