The EGO POWER+ LM2135SP is a premium cordless electric lawn mower that pairs a powerful self-propelled drive system with two high-capacity batteries—a 7.5Ah and a 5.0Ah—for extended runtime on medium to large lawns. It’s designed for homeowners who want gas-level performance without the fuel, noise, or maintenance headaches, and it’s especially suited for those with lawns between 1/3 and 1/2 acre who value convenience and reliability.
Who Should Buy This
1. Homeowners with 1/3 to 1/2 acre lawns – The included 7.5Ah battery handles most of the work, while the extra 5.0Ah battery gives you a seamless backup. You’ll likely finish the entire yard on one charge, but the second battery removes any anxiety about running out of juice mid-mow.
2. Gas mower converts who hate maintenance – If you’re tired of oil changes, stale fuel, spark plug swaps, and carburetor cleaning, this mower is your ticket out. The brushless motor is sealed and virtually maintenance-free—just sharpen the blade annually and store it away.
3. Homeowners who value quiet operation – At around 72 decibels, this mower is significantly quieter than most gas models. You can mow early Saturday morning without waking the neighbors or disturbing sleeping kids.
4. Users with sloped or uneven terrain – The variable-speed self-propelled drive (with a lever control) gives you precise control on hills. It’s not a zero-turn, but for a residential push mower, it climbs better than most.
Key Features Breakdown
56V 7.5Ah ARC Lithium Battery + Extra 5.0Ah Battery – This is the star of the show. The 7.5Ah battery delivers about 45–60 minutes of runtime under normal conditions; the 5.0Ah adds another 30–40 minutes. Together, you can easily mow a 1/2-acre lawn in one go. The rapid charger refills the 7.5Ah in about 50 minutes.
Self-Propelled Variable Speed Drive – The lever-controlled rear-wheel drive lets you dial in your walking pace from 0 to 3.5 mph. It’s responsive and smooth, with no jerky starts. Great for changing speed on the fly when you hit a thick patch or a slope.
21-Inch Steel Deck with Dual Blades – The steel deck is sturdy and won’t flex under stress. The dual blades create a finer clip and better mulching than single-blade designs. It also has a rear-bagging option and side discharge, though the side chute is sold separately.
Weather-Resistant Construction – EGO uses IPX4-rated electronics (splash-proof). You can mow wet grass without worrying about short circuits, though you shouldn’t submerge it.
LED Headlights – Two bright LEDs illuminate the cutting path in low light. Useful for evening mows when you lose daylight.
7-Position Single-Point Height Adjustment – One lever adjusts all four wheels simultaneously, from 1.5 to 4 inches. It’s quick and easy to change heights between seasons or for different grass types.
Pros
-
Exceptional runtime with two batteries – Most competitors sell a single battery. Having a 7.5Ah and a 5.0Ah means you can mow a large lawn without waiting for a recharge.
-
Smooth, intuitive self-propelled drive – The lever control feels natural and responds instantly. It’s far better than the push-button or dial-based systems on some rivals.
-
Powerful mulching performance – The dual blades chop grass into fine particles that disappear into the turf. You’ll rarely need to bag unless the grass is excessively tall.
-
Quiet and clean operation – No exhaust fumes, no earplugs needed. You can mow in shorts and a t-shirt without smelling like a gas station.
-
Sturdy build quality – The steel deck and thick plastic housing feel solid. It folds flat for vertical storage, taking up minimal garage space.
-
EGO’s battery platform – If you already own EGO tools (trimmers, blowers, chainsaws), this battery works across the line. The 56V system is one of the most reliable in the cordless OPE market.
Cons
-
High upfront cost – At nearly $900, this is a serious investment. You’re paying for the premium batteries and rapid charger. If you only have a small lawn (under 1/4 acre), a cheaper model with a single battery might suffice.
-
Side discharge chute sold separately – For a mower at this price point, including the side chute would be nice. It’s an extra $30–40 if you need it for tall grass mulching or bagging alternatives.
-
Battery weight – The 7.5Ah battery is heavy (about 4.5 lbs). While the self-propelled drive handles the mower’s weight, carrying the battery to the charger or swapping it mid-mow can feel cumbersome.
-
Plastic wheel hubs – The wheels are durable, but the plastic hubs can crack if you hit a large rock or tree root hard. It’s not a common issue, but it’s worth noting for rocky yards.
Bottom Line
The EGO POWER+ LM2135SP with the extra 5.0Ah battery is the best cordless mower for homeowners with medium to large lawns who want gas-grade power without the mess. The runtime is class-leading, the self-propelled drive is smooth, and the dual-blade mulching system leaves a clean finish. Yes, it’s expensive, but the two-battery bundle saves you from buying a second battery later—and the build quality justifies the price for serious lawn care enthusiasts. If your lawn is over 1/3 acre and you hate dealing with gas, this is the mower to buy.
Frequently Asked Questions
Q: How long does the 7.5Ah battery last on a single charge?
A: In typical conditions (medium-height grass, self-propelled on flat ground), expect 45–60 minutes. With the included 5.0Ah battery as backup, you’ll get about 75–90 minutes total. Thick, wet, or tall grass reduces runtime by 20–30%.
Q: Can I use the extra 5.0Ah battery in other EGO tools?
A: Yes. The BA2800T battery is compatible with all EGO 56V tools, including trimmers, blowers, chain saws, and edgers. It’s a valuable addition to the EGO ecosystem.
Q: Does it work well on thick St. Augustine or Bermuda grass?
A: Yes, but you’ll want to keep the blade sharp and mow at a higher setting (3–4 inches) for
How It Compares
Quick Verdict
The EGO POWER+ wins for versatility and power, handling larger yards with ease, while the eufy E15 excels in hands-free convenience for small, flat lawns.
Side-by-Side Comparison
| Feature | Mower A: EGO POWER+ (LM2135SP) | Mower B: eufy Robot E15 |
|---|---|---|
| Price | $898.99 | $999.99 |
| Power Source | 56V cordless electric (2 batteries: 7.5Ah + 5.0Ah) | Battery-powered robot (rechargeable, no extra battery) |
| Cutting Width | 21 inches | 8 inches (estimated, based on robot size) |
| Self-Propelled | Yes (variable speed, rear-wheel drive) | No (fully autonomous robot) |
| Best Yard Size | Up to 1 acre (with dual batteries) | 0.2 acres (maximum recommended) |
| Warranty | 5-year limited (tool), 3-year (batteries) | 1-year limited |
Where EGO Wins
- Power and Cutting Performance: The 56V system with a 7.5Ah battery delivers strong torque for thick grass, wet conditions, and slopes up to 15°. The 21-inch steel deck cuts faster than the eufy’s small robot blades, which struggle with tall or dense turf.
- Yard Size Flexibility: With two batteries (7.5Ah + 5.0Ah), the EGO can handle up to 1 acre on a single charge—five times the eufy’s 0.2-acre limit. It’s ideal for medium to large lawns without needing a gas mower.
- Durability and Warranty: The EGO has a 5-year warranty on the mower and 3 years on batteries, backed by a brand known for commercial-grade components. The eufy’s 1-year warranty is shorter, and robot mowers are more prone to mechanical issues (e.g., wheel motors, sensors).
Where eufy Wins
- Fully Autonomous Operation: The eufy mows entirely on its own using RTK-free GPS mapping and AI 3D obstacle avoidance. No pushing, no starting—just schedule via the app and let it work daily for a consistently trimmed lawn.
- Wire-Free Installation: Unlike traditional robot mowers that require buried boundary wires, the eufy uses Pure Vision navigation (GPS + cameras). Setup takes minutes—just place the charging station and define zones in the app.
- Stealth and Security: The eufy operates silently (under 60 dB) and includes GPS anti-theft tracking. It’s perfect for small front yards where noise is a concern or theft risk exists, and it handles slopes up to 18° without tethering.
Which Should You Buy?
- Buy Mower A (EGO POWER+) if: You have a lawn larger than 0.2 acres, deal with thick or uneven grass, or want a reliable, powerful mower that you can control manually. It’s better for yards with trees, flower beds, or irregular shapes where a robot might get stuck.
- Buy Mower B (eufy E15) if: You have a small, flat lawn under 0.2 acres and want zero physical effort. It’s ideal for busy homeowners who value convenience over speed—let it mow daily while you’re at work.
- Consider both if: Your yard is 0.2–0.3 acres with simple terrain. The EGO offers faster cuts and more power, but the eufy provides hands-free maintenance. For most buyers, the EGO’s versatility and longer warranty make it the better value, despite the higher initial effort.
Quick Verdict
The EGO POWER+ wins overall for most homeowners due to its superior power, proven reliability (4.7/5 stars), and better value at $898.99—especially if you have a yard larger than 1/4 acre or want hands-on control.

Where EGO Wins
-
Power and Cutting Performance – The EGO’s 56V system delivers gas-like torque, easily handling thick, wet, or tall grass. Its 21-inch steel deck cuts faster and leaves a cleaner finish than the Segway’s small 8.5-inch plastic blades, which struggle with dense growth or uneven terrain.
-
Battery Life and Runtime – The included 7.5Ah battery plus an extra 5.0Ah battery gives you a combined 12.5Ah capacity—enough to mow up to 1 acre on a single charge. The Segway’s internal battery lasts about 60–90 minutes (roughly 1/4 acre) and takes 2+ hours to recharge.
-
User Control and Reliability – With self-propelled drive and manual steering, you have full control over speed, direction, and cutting height (adjustable from 1.5 to 4 inches). The EGO has a 4.7-star rating from 618 reviews, reflecting consistent performance and durability, while the Segway’s 3.9-star rating indicates more mixed feedback on mapping accuracy and obstacle handling.
Where Segway Wins
-
Fully Autonomous Operation – The Segway Navimow mows entirely on its own after initial setup. Using RTK+Vision GPS and AI-assisted mapping, it learns your yard, avoids obstacles, and returns to its charging station automatically—no pushing or supervising required.
-
No Perimeter Wire or Manual Effort – Unlike traditional robot mowers, the Segway uses virtual boundaries set via app, so you never bury wire. This makes installation simpler and allows easy boundary adjustments from your phone. Ideal for tech-savvy users who want a “set it and forget it” solution.
-
Quiet and Safe – At 58 dB(A), the Segway is whisper-quiet compared to the EGO’s 78 dB. It’s safe for pets and kids to be nearby, and its small size lets it mow under low-hanging branches and tight garden edges without manual trimming.
Which Should You Buy?
Buy Mower A (EGO POWER+) if:
- Your yard is larger than 1/4 acre (up to 1 acre)
- You want maximum power, faster mowing, and reliable cutting in all grass conditions
- You prefer hands-on control and don’t mind spending 30–60 minutes mowing yourself
Buy Mower B (Segway Navimow) if:
- Your yard is 1/4 acre or less with simple, open terrain
- You prioritize zero manual labor and want a fully autonomous mower
- You’re comfortable with app-based setup and occasional firmware updates
Buy neither if:
- Your yard is over 1 acre—consider a gas mower or a larger robot like Segway’s i150N (priced $1,499+)
- You want a budget option under $500—look at manual reel mowers or entry-level electric push mowers
