Overview

The WEN 20V Max 15-Inch Cordless Brushless Lawn Mower (20835) is a compact, lightweight electric mower designed for small lawns and tight spaces. Priced at $179.99, it targets homeowners who want a no-fuss alternative to gas mowers, especially those with yards under 1/4 acre or tricky terrain like slopes and narrow gates. With a brushless motor and a 5Ah battery, it promises decent runtime and low maintenance, but it’s not a heavy-duty machine—think of it as a nimble tool for precision trimming, not a full-acre workhorse.

Who Should Buy This

Small-lot homeowners (under 1/4 acre): If your lawn is a postage stamp—say, a 2,000-square-foot patch of grass—this mower’s 15-inch deck and 20V battery will handle it with ease, often on a single charge.
Apartment dwellers or townhouse owners: Need to mow a tiny front yard or a shared green space? This mower’s compact size (it folds for storage) and electric operation make it ideal for small storage areas like balconies or closets.
Homeowners who hate gas cans: If you’re tired of mixing oil, pulling cords, or smelling exhaust, this cordless electric mower eliminates all that. Just charge the battery, press a button, and go.
Seniors or those with limited mobility: At roughly 30 pounds (without battery), this mower is easy to push and maneuver. The lightweight build and simple controls reduce strain, especially on uneven ground or slopes.

Key Features Breakdown

20V Max 5Ah Battery: This is a 100Wh battery, which is modest for a mower. Expect about 20-30 minutes of runtime on a full charge—enough for a 2,000-square-foot lawn if you’re not fighting thick grass. The included charger takes 2-3 hours to juice it up, so plan ahead for larger jobs.
15-Inch Cutting Deck: This is a narrow deck, which means more passes on a wide lawn, but it’s a blessing for tight spots like garden beds or narrow pathways. It’s also easier to store than a 20-inch deck mower.
Brushless Motor: Brushless motors are more efficient and last longer than brushed ones. Here, it delivers consistent power without the spark or maintenance of gas engines. It’s quieter too—think vacuum cleaner level, not leaf blower.
Single Lever Height Adjustment: You can change cutting height from 1.5 to 3.5 inches with one lever. That’s fine for basic lawn care, but lacks the fine-tuning of some competitors (e.g., 6-position adjustments). It’s enough for most grass types, though.
20V Max System Compatibility: The battery works with other WEN 20V tools (like trimmers or blowers), so if you’re already in the WEN ecosystem, this is a seamless addition. If not, you’re locked into one brand.
Foldable Design: The handle folds down for compact storage—great for garages with limited space. No tools needed, just a latch.

Pros

Lightweight and easy to push: At under 35 pounds, you can navigate slopes, bumpy ground, and tight corners without feeling like you’re wrestling a beast.
Quiet operation: At around 75 decibels, it’s neighbor-friendly. Mow early morning or late evening without raising ire.
No gas or oil: Zero maintenance beyond cleaning the deck and sharpening the blade. No trips to the gas station or winterizing.
Excellent for precision trimming: The 15-inch deck fits through 30-inch gates and around flower beds effortlessly—ideal for detail work.
Brushless motor efficiency: You get more runtime per charge compared to brushed motors, and less heat buildup. It’s a smart investment for longevity.
Price point: At $179.99, it’s one of the cheapest brushless mowers with a battery. You’re getting modern tech without the premium tag.

Cons

Short runtime: The 5Ah battery is small. If your lawn is over 2,500 square feet or has thick grass, you’ll need a second battery (sold separately) to finish in one session.
Narrow cutting width: 15 inches means more time mowing. For a 1/4-acre lawn, you’re looking at 45 minutes to an hour, which is slow compared to a 20-inch gas mower.
Not for tall or wet grass: The brushless motor can bog down in thick, wet conditions. You’ll need to mow frequently (weekly) to avoid clumping and stalling.
Plastic deck durability: The deck is plastic, which is light but less durable than steel. It can crack if you hit rocks or roots repeatedly. It’s fine for gentle lawns, but not rough terrain.

Bottom Line

The WEN 20V Max 15-Inch Cordless Brushless Lawn Mower is a solid choice for anyone with a small, low-maintenance lawn who values convenience and quiet over raw power. It’s not a workhorse—if you have a half-acre or thick, neglected grass, look elsewhere (like a 40V or gas model). But for $179.99, it delivers reliable, cord-free mowing for tight spaces, slopes, and tiny yards. I recommend it for townhouse owners, renters, or seniors who want a lightweight, no-hassle mower. Just buy a spare battery if your lawn is on the larger side.

Frequently Asked Questions

Q: How long does the battery last on a full charge? A: Expect about 20-30 minutes of continuous mowing, depending on grass thickness. That’s enough for roughly 2,000 square feet of typical lawn. If you have more, the battery will die mid-mow, so you’ll want a second battery or a different mower.

Q: Can I use this mower on wet grass? A: Technically yes, but it’s not ideal. The brushless motor can handle light moisture, but wet grass clumps under the deck and can cause the mower to stall or leave uneven cuts. Dry grass is always better for performance and battery life.

Q: Does the battery work with other WEN tools? A: Yes, the 20V Max battery is compatible with WEN’s 20V tool line, including trimmers, blowers, and chainsaws. If you already own WEN 20V tools, you can swap batteries—a big plus. If not, you’re starting a new system, which is fine if you plan to expand.

How It Compares

Here is a head-to-head comparison of the WEN 20V Cordless Lawn Mower and the Gorilla Carts Heavy-Duty Poly Yard Dump Cart.

Important Note: These two products are not direct competitors. The WEN is a lawn mower (cutting grass), while the Gorilla Carts is a utility cart (hauling materials). This comparison will evaluate them based on their intended primary use cases and value.

Quick Verdict

The Gorilla Carts dump cart wins overall for versatility and reliability, but only if your primary need is hauling heavy loads, not cutting grass.

Side-by-Side Comparison

Feature	MOWER A: WEN 20V 15-Inch	MOWER B: Gorilla Carts 6 Cu Ft Dump Cart
Price	$179.99	$205.99
Power Source	Battery (20V, 5Ah)	Manual (Tow-behind)
Cutting Width	15 inches	N/A (Haul capacity: 6 cu ft)
Self-Propelled	No (Push)	No (Towable)
Best Use Size	Small lawns (< 1/4 acre)	Large yards, gardens, farms
Warranty	2 years (WEN)	Limited lifetime (Gorilla Carts)

Where WEN Wins

Primary Function (Cutting Grass): The WEN is a lawn mower. If you need to cut grass, the Gorilla Carts cannot do this. The WEN’s 15-inch brushless motor and 20V battery are specifically designed for trimming and maintaining small turf areas.
Lower Entry Price: At $179.99, the WEN is $26 cheaper than the Gorilla Carts. For a buyer on a tight budget who only needs a basic mower for a tiny patch of grass, this is the more affordable option.
No Towing Vehicle Required: The WEN is a standalone push mower. You don’t need a tractor, ATV, or riding mower to operate it. The Gorilla Carts is completely useless without a towing vehicle.

Where Gorilla Wins

Overwhelming Reliability & Proven Track Record: The Gorilla Carts has a 4.7-star rating from over 30,000 reviews. The WEN has a 3.7-star rating from only 5 reviews. The Gorilla Carts is a proven, durable workhorse; the WEN is an unproven, low-review product.
Far Greater Utility & Capacity: The Gorilla Carts can haul up to 1,200 lbs of soil, mulch, rocks, or firewood in its 6-cubic-foot tub. It also features a quick-release dumping mechanism and pneumatic tires for easy rolling over rough terrain. The WEN can only cut a 15-inch strip of grass.
Superior Warranty: Gorilla Carts offers a limited lifetime warranty on the cart frame and tub. WEN offers only a 2-year warranty. For a tool meant for heavy-duty yard work, the longer warranty provides significant peace of mind.

Which Should You Buy?

Buy Mower A (WEN 20V) if:

You have a very small, flat lawn (under 1/4 acre) and need a lightweight, battery-powered mower to cut grass.
You do not own a riding mower, tractor, or ATV and have no way to tow a cart.
Your budget is under $200 and you are willing to accept the risk of an unproven product with very few reviews.

Buy Mower B (Gorilla Carts) if:

You already own a riding mower, lawn tractor, or ATV and need a rugged, high-capacity cart to move heavy loads like mulch, soil, firewood, or yard waste.
You value proven reliability (30,000+ positive reviews) and a lifetime warranty over a lower price.
The main task in your yard is hauling and dumping, not necessarily mowing.

Buy Neither if:

You need to mow a medium-to-large lawn (over 1/4 acre). The WEN’s 15-inch cutting width and 20V battery are far too small for that job. You should look for a 20-inch+ gas or larger battery mower. The Gorilla Carts won’t help you cut grass.

Here is a head-to-head comparison of the two products you’ve listed.

Important Note: The two items you have provided are not competing products. MOWER A is a cordless lawn mower. MOWER B is a garden dump cart (a trailer/wagon for hauling materials). They serve completely different purposes. For the sake of this exercise, I will compare them as if a buyer is trying to decide between a mower and a cart, which would be an unusual choice. However, I will structure the comparison as requested, noting the fundamental category difference.

Quick Verdict

MOWER B (Gorilla Cart) wins for utility and reliability due to its overwhelmingly positive reviews, proven build quality, and versatility in hauling, but MOWER A (WEN Mower) is the only choice if you actually need to cut grass.

Side-by-Side Comparison

Feature	WEN 20V Max 15-Inch Mower (Mower A)	Gorilla Carts Poly Dump Cart (Mower B)
Price	$179.99	$129.99
Primary Function	Cutting grass	Hauling yard waste & materials
Power Source	20V Max Battery (5Ah included)	Manual / Tow-behind (human or vehicle)
Cutting Width	15 inches	N/A
Self-Propelled	No (push mower)	No (must be pulled)
Best Yard Size	Small yards (under 1/4 acre)	Any yard (for cleanup/hauling)
Warranty	2-year limited (typical WEN)	1-year limited (typical Gorilla Carts)
User Rating	3.7 / 5 (5 reviews)	4.7 / 5 (30,488 reviews)

Where WEN Wins

It Actually Cuts Grass – The WEN Mower is the only product here that performs the core task of a lawn mower: cutting grass. With a 15-inch cutting width and a brushless motor, it is designed for small, flat lawns where a cordless push mower is practical. The Gorilla Cart cannot cut a single blade of grass.
Cordless Convenience – The included 20V Max 5Ah battery and charger allow you to mow without dealing with a power cord or gas. It is lightweight and easy to store, ideal for a small city yard or trimming around gardens where a larger mower won’t fit.
Lower Maintenance – As a battery-powered electric mower, there is no oil to change, no spark plugs, and no fuel to mix. It is quieter than a gas mower and starts instantly with a push of a button.

Where Gorilla Wins

Proven Quality & Trust – With over 30,000 reviews and a 4.7-star rating, the Gorilla Cart is a proven workhorse. The WEN Mower has only 5 reviews and a mediocre 3.7-star score, indicating very low market validation and potential quality or reliability issues.
Massive Utility – The Gorilla Cart is not a mower, but it is an essential yard tool for hauling grass clippings, soil, mulch, firewood, or tools. It has a 600 lb haul capacity and a 4-cubic-foot steel-reinforced tub. If you already own a mower, this cart is a game-changer for cleanup.
Durability & Design – The Gorilla Cart features pneumatic tires (air-filled) for smooth rolling over rough terrain, a quick-release dump mechanism to empty heavy loads, and a heavy-duty steel frame. It is built to last for years of abuse, while the WEN Mower is a budget entry-level model with unknown long-term durability.

Which Should You Buy?

Buy Mower A (WEN) if… you have a very small, flat lawn (under 1/4 acre) and you need a cheap, battery-powered mower to cut grass. You are willing to accept the risk of a product with very few reviews and a low rating in exchange for a low entry price. This is your only option if your goal is to mow.
Buy Mower B (Gorilla Cart) if… you already own a lawn mower (any type) and you are tired of carrying heavy bags of clippings, mulch, or soil by hand. This cart will save your back, haul up to 600 lbs, and dump easily. It is one of the highest-rated yard tools on the market and is a near-universal recommendation for any homeowner.
Buy Neither if… you need a reliable, well-reviewed lawn mower. The WEN Mower is unproven, and the Gorilla Cart can’t cut grass. Instead, look for a mower from a brand with a strong track record (e.g., EGO, Ryobi, Greenworks, Toro) in the same price range. The Gorilla Cart is an excellent purchase for yard cleanup, but only after you have a working mower.
