Thinking about whether to go electric or stick with gas for your lawn mower? For most suburban yards (flat lawns under 2,000m² / 0.5 acres), an electric mower is the better option. It's less expensive to operate, kinder to the environment, noticeably quieter, and easier to maintain. Most electric mowers can also cover suburban lots in one charge.
That said, gas mowers still make sense if you've got tough terrain or a bigger lawn (over 2,000m² / 0.5 acres). In this comparison, we'll break down where each type shines, so you can pick the mower that fits your yard and routine.
Electric vs Gas Lawn Mower: Where Electric Lawn Mower Wins
Here's where electric lawn mowers are better than gas lawn mowers: they have quieter operations, zero local emissions, minimal maintenance, fast startup, and lower running costs.
Quieter operations: A corded or battery electric mower runs at around 75dB. Gas mowers run at around 90 dB. Think of 75dB as the noise a vacuum cleaner or washing machine makes. At 90dB, the noise can sound like a motorcycle engine. Ear protection for prolonged exposure is needed.
Zero local emissions: Electric mowers don't produce fumes and exhaust smell, unlike gas mowers. This is important if you're mowing in an enclosed backyard, near open windows, or around kids and pets.
Minimal maintenance: Electric mowers don't require oil changes or spark plug replacement. Charge it, mow your lawn, put it away.
Fast startup: If you've spent ten minutes coaxing a gas mower to life, an electric mower's instant startup makes a big difference. Just press a button and start mowing.
Lower running costs: An electric mower runs on electricity that typically costs a fraction of a tank of gas. Meanwhile, a gas mower requires you to spend on fuel and regular maintenance, like oil, spark plugs, and air filter replacements.
Electric vs Gas Lawn Mower: Where Gas Lawn Mower Wins
Despite heavy maintenance and noise, gas mowers are still better than electric mowers in four areas. They give you sustained power for tall, wet, or thick grass, unlimited runtime, a better fit for lawns over 2,000m² (0.5 acres), and they operate in power outages.
Sustained power for tall, wet, or thick grass: Prolonged rain can cause your unmowed lawn to develop thick, tall, wet overgrowth and matted patches of grass. Overgrown grass creates more resistance on a mower's blade, especially when wet. Gas mowers are better than electric mowers at maintaining cutting power in these conditions.
Unlimited runtime: Because you can refill its fuel in just 30 seconds, gas mowers let you mow for hours. If it stops midway, an electric mower may need 30 minutes or more to recharge.
Lawns over 2,000m² (0.5 acres): Gas mowers' 30-second refill time is good for mowing large lawns. An electric mower's single battery charge covers a small-to-medium yard, not half an acre or more.
Runs in power outages: In prolonged power outages, a gas mower can help you maintain your yard and avoid overgrowth.
Important: If you're still considering an electric mower over a gas mower for a lawn over 2,000m² (0.5 acres), find out the mower's real-world runtime before buying. A 40-minute battery can struggle in large lawns.
The Cost Breakdown: Upfront vs Long-Term
A lawn mower will likely stay in your shed for 7 to 10 years, so the upfront price is only part of what you'll actually pay. Once you consider fuel and maintenance, an electric mower usually comes out lower than a gas mower over five years, even though it costs more to buy.
Upfront costs: Electric mowers usually cost more to buy than gas push mowers, mostly because of the battery. However, the gap has been shrinking as batteries get cheaper.
Running costs: Charging an electric mower over one mowing season typically costs around $14–$27 CAD in electricity. Fueling a gas mower over the same season runs about $41–$82 CAD.
Maintenance: Cordless electric mowers need a battery replacement every 3 to 5 years and very little else in between. Gas mowers need recurring upkeep year after year. Engine maintenance like oil and spark plug changes is one cost, and annual winterization (end-of-season fuel and oil prep before storage) is another.
Pro-tip: Check whether your local utility offers a rebate on electric yard equipment. Many do, especially in regions phasing out gas-powered lawn equipment. A rebate can offset a meaningful share of the upfront price gap.
Other Factors: Noise, Emissions, and Weather
Before you buy, consider these other factors that often get overlooked: what your municipality allows, what your province or state regulates, and how the mower handles wet grass.
Local noise rules: Many cities and towns restrict gas-powered yard equipment in the early morning, late evening, and on weekends. If you mow before work or on a Sunday afternoon, an electric mower lets you mow whenever it suits you.
Emissions regulations: Some regions have started phasing out new sales of gas-powered lawn mowers, with more expected to follow. If you're buying a mower you'll use for the next 7 to 10 years, electric may be the safer long-term bet.
Wet grass handling: Most electric mowers can handle damp grass, but manufacturers tend to advise against it. Wet grass can strain the motor and tear blades instead of cutting them cleanly. If your lawn needs cutting and you can't wait for it to dry, raise the cutting height and slow your pace.
A Third Option: Skip Both With a Robot Lawn Mower
Why pick between gas and electric when you can skip mowing altogether? A robot mower does the job for you. It runs on its own and charges itself. You may pay more upfront than either alternative, but it frees up your weekends.
The Dreame A3 AWD 1000 retails at $2,299.99 CAD, and covers up to 1,000m² (0.25 acres) on a single charge. When the battery runs low, it returns to its dock to recharge before picking up where it left off. Setup is straightforward, and once it's done, the mower runs on its own schedule.
A weekly mow takes 30 to 60 minutes on an average suburban lawn. Over the 7-to-10-year lifespan of a typical mower, that's 200 to 400 hours of your weekends. A robot mower gives you those hours back. Your lawn ends up healthier too, since frequent short cuts are better for grass than weekly long ones.
The A3 AWD 1000 is the entry point into Dreame's A3 AWD lineup. This Dreame A3 AWD Pro review walks you through the higher-end model in the same series, which gives a good sense of how setup and daily use work across the range.

Important: Most capable robot lawn mowers can start to struggle once lawns push past 6,000m² (1.48 acres) or slopes exceed 80% (38.7°), and gas is still the better fit there. For everything below that range, though, today's robot mowers handle the job well, including yards with slopes, edges, and obstacle-heavy layouts that would have stopped earlier models.
Choosing the Right Mower for Your Yard
The right mower depends on your yard and how much time you want to spend on it. Gas still earns its place on large lawns or rough terrain, but for a flat suburban yard, electric is the simpler and cheaper choice. And if mowing isn't how you want to spend your weekends, a robot mower takes the job off your hands.
If a robot mower fits your yard, Dreame's collection of robot lawn mowers is a fantastic starting point. The A3 AWD series covers a range of yard sizes, from small backyards up to lawns approaching an acre.
Frequently Asked Questions
Which is better, gas or electric lawn mower?
For most suburban lawns under 2,000m² (0.5 acres), an electric lawn mower is the better choice today. It's quieter, cheaper to run, and needs far less upkeep. A gas mower is still the right pick for larger lawns, rough terrain, or yards with thick or wet grass where electric mowers can lose power.
What are the drawbacks of electric lawn mowers?
The main drawback is runtime. Cordless models usually run for 30 to 60 minutes on a full charge, which is fine for a small yard but tight for anything approaching half an acre. If the battery runs out mid-mow, you'll need to wait for it to recharge before finishing.
Electric mowers usually cost more upfront than gas models, though batteries are becoming cheaper. Lower-end models with smaller motors can also bog down in tall or wet grass. And while corded electric mowers solve the runtime problem, the cord itself is awkward to manage around trees, beds, and obstacles.
Is it okay to cut wet grass with an electric lawn mower?
Yes, modern electric mowers are built to cut wet grass safely. The bigger issue is performance. Wet grass clogs the underside of the mower, dulls the cut, and tears blades of grass instead of slicing them cleanly. Most manufacturers advise against it for that reason.
If you do mow in wet conditions, raise the cutting height and slow your pace to give the mower more time to cut through each pass.
How much does it cost to run an electric mower vs gas?
Electric mowers cost less to run than gas mowers in every region. Electricity for an electric mower runs about $14–$27 CAD per season for an average suburban lawn, while gas runs $41–$82 CAD. Gas prices fluctuate, while electricity rates are more stable, which makes electric running costs easier to predict.
What if I don't want to mow at all?
You can hire a lawn service or get a robot mower. A professional lawn service makes sense if your lawn is over 4,000m² (1 acre) or has slopes past 80% (38.7°) that a robot mower can't handle. You pay per visit with no upfront cost, but the bill repeats every season.
Robot lawn mowers make sense if your lawn fits within a model's coverage range. Once it's set up, it mows on its own schedule and charges itself. You don't need to be home. A robot mower has a higher upfront cost but pays for itself within a few seasons if you'd otherwise pay for weekly cuts.
