2×20V 18 Inch Cordless Lawn Mower, Electric Push Mower with 6-Position Height Adjustment, 2-in-1 Mulching/Bagging, 2×5.0Ah Batteries & Charger Included Review

Overview

The Height 2×20V 18 Inch Cordless Lawn Mower is a compact, battery-powered push mower designed for small to medium-sized lawns—think city lots, townhouses, or suburban yards up to about 1/4 acre. It runs on two 20V 5.0Ah batteries (included), offers a 2-in-1 mulching and bagging system, and gives you six cutting heights from 1 to 3 inches. At $189.99, it’s positioned as an affordable entry point for homeowners who want to ditch gas cans and extension cords without spending a fortune.

Who Should Buy This

• Small-lot homeowners (up to 1/4 acre): If your lawn is more postage stamp than pasture, this mower’s 18-inch deck and twin 5.0Ah batteries will handle the job on a single charge—no need for a bigger, pricier machine.
• First-time cordless buyers: If you’re tired of pulling a gas mower’s starter cord or tripping over an electric cord, this is a low-risk, budget-friendly way to go battery-powered. The included batteries and charger mean zero extra purchases.
• Renters or apartment dwellers with a patch of grass: Lightweight (under 40 lbs) and compact, it’s easy to haul upstairs or stash in a closet. The foldable handle saves space.
• Homeowners who hate maintenance: No oil changes, no spark plugs, no stale gas. Just charge, mow, and store.

Key Features Breakdown

• 2×20V 5.0Ah Batteries: The dual-battery system delivers more runtime than a single 4.0Ah pack—expect about 30-40 minutes of continuous mowing on a well-maintained lawn. One battery powers the mower while the other can charge, so you can swap and keep going for up to an hour total. Real-world tip: if your grass is thick or damp, runtime drops by 20-30%.
• 18-Inch Cutting Deck: This is a narrow deck, which means more passes on a larger lawn. But for tight spaces, garden beds, and gates, it’s nimble. It cuts cleanly up to about 2 inches tall; taller grass may require a second pass.
• 6-Position Height Adjustment: Single-lever adjustment (no bending to each wheel) from 1 to 3 inches. That’s a decent range for cool-season grasses like fescue or ryegrass, but warm-season Bermuda or Zoysia lovers may find the top end too low for summer scalping.
• 2-in-1 Mulching/Bagging: The mulching plug is included—just slide it in to chop clippings fine and return nutrients to the soil. The bag is a hard plastic rear catcher (not a cloth bag), which holds about 1.2 bushels. It fills quickly on thick grass, so you’ll empty it often.
• Battery & Charger Included: No hidden costs. The charger is a standard 20V lithium-ion unit (2-3 hour charge time per battery). Both batteries are compatible with other 20V tools in the Height ecosystem, if you expand later.

Pros

1. Great value for the price: At $189.99 with two batteries and a charger, this is one of the cheapest cordless mowers on the market. Comparable models from big brands often cost $250+.
2. Lightweight and easy to maneuver: At around 35-38 lbs, it’s easy to push, turn, and lift over curbs or into a car trunk. Great for seniors or anyone with limited strength.
3. Quiet operation: It’s noticeably quieter than a gas mower—you can mow early Saturday morning without waking the neighbors.
4. Simple height adjustment: The single-lever system is quick and tool-free. No crawling around to adjust each wheel individually.
5. Foldable handle for storage: The handle collapses with a thumb latch, reducing the footprint to about 2 feet tall. Fits in a closet, under a workbench, or in a small shed.
6. No gas, no cord, no fuss: Instant start with a push button, no priming or choking. Just press and go.

Cons

1. Limited runtime on thick grass: The 5.0Ah batteries are decent, but if your lawn is dense, damp, or overgrown, you’ll get 20-25 minutes per pair. That’s enough for about 2,000-3,000 sq ft, not a full 1/4 acre.
2. Small bag capacity: The 1.2-bushel bag fills up fast, especially when bagging. Expect to empty it every 5-7 minutes on a typical lawn. Mulching is the better option for this mower.
3. No self-propel: This is a push mower only. On flat ground, it’s fine. On a slope or hill, you’ll be working harder than with a self-propelled model.
4. Deck can clog in wet grass: Like many budget mowers, the plastic deck doesn’t handle wet, heavy clippings well. You’ll need to stop and clear it more often than with a steel-deck mower.

Bottom Line

The Height 2×20V Cordless Lawn Mower is a solid, no-frills choice for homeowners with small, flat lawns who want to go battery-powered without breaking the bank. It’s quiet, lightweight, and easy to store—perfect for a 2,000-3,000 sq ft yard where you mow weekly. The dual-battery system and 6-position height adjustment are genuine perks at this price. But if your lawn is larger than 1/4 acre, has hills, or you hate emptying a small bag, look for a self-propelled model with a bigger deck. For the price, though, this mower delivers exactly what it promises: a simple, clean cut with minimal hassle. I’d recommend it for first-time cordless buyers or as a backup mower for tight spaces.

Frequently Asked Questions

Q: How long do the batteries last on a full charge? A: With both 5.0Ah batteries, you’ll get about 30-40 minutes of mowing on dry, short grass. If the grass is tall or damp, expect 20-25 minutes. Plan your mowing session accordingly—charge both batteries fully before you start.

Q: Can I use other brand batteries with this mower? A: No. This mower uses Height’s proprietary 20V battery system. Only Height-branded 20V batteries (or compatible models from the same platform) will work. Stick with the included 5.0Ah batteries for best performance.

Q: Does it handle thick St. Augustine or Bermuda grass? A: It can, but with caveats. The 18-inch deck and single blade are fine for thin-bladed grasses. For thick St
