Snow Blowers: Single-Stage vs Two-Stage vs Cordless, Which to Buy

Buy a single-stage snow blower for paved driveways that usually get under about 9 inches of snow. Buy a two-stage machine for deeper, wetter snow and the bank the plow leaves at the curb. Gas and cordless battery versions now exist for both types, so choose the power source by driveway size and runtime.

Single-stage or two-stage: what is the difference?

A single-stage machine uses one spinning auger to scoop snow and throw it out the chute. Toro calls its version a Power Curve rotor. The auger runs close to the ground, which is why Ariens says its single-stage Path-Pro cleans down to the pavement.

A two-stage machine splits the job. A slower auger gathers snow and feeds it to a fast impeller behind it, which throws it. Ariens lists a steel serrated auger and a three-blade steel impeller on its Deluxe 28. Two-stage housings stand taller, so they take bigger bites of deep snow.

How do the specs compare?

Every value below comes from the maker’s own spec page for the model named. “Intake height” is the maker’s term; Snow Joe calls it depth of snow cut, Ryobi calls it clearing depth and Ariens calls it housing height.

A few patterns stand out. The single-stage machines cluster at 21 to 22 inches wide with a 12.5 to 13 inch intake. The two-stage machines run 22 to 28 inches wide with intakes of 18 to 21 inches.

Throw distance grows with the stage too. Toro lists up to 35 feet for the 721 R and up to 45 feet for the 826 OHAE. Ariens and EGO both list up to 50 feet for their two-stage models.

Who should buy a single-stage snow blower?

A single-stage machine fits a short or mid-size paved driveway, walks and a patio in places where most storms bring a few inches. Toro describes the Power Clear 721 R as designed for residential use on paved surfaces, and Ariens recommends up to 9 inches for its Path-Pro.

Corded electric models are the lightest option. Snow Joe lists the SJ627E at 34.6 pounds and aims it at light, fluffy snow. The trade-off is the cord. CPSC reminds owners of electric snow throwers to know where the power cord is at all times.

Cordless single-stage machines remove the cord. Toro’s 60V Power Clear matches the gas 721 R on width and intake height, and Toro says it can clear up to a 15-parked-car driveway on one charge.

Who should buy a two-stage snow blower?

Choose two-stage if storms regularly bring more than about 9 inches, if the snow is heavy and wet, or if a long driveway ends at a plowed street. The taller intake is the key number. Toro’s 826 OHAE takes 20 inches and is rated ideal up to 12 inches of snow.

Two-stage machines are self-propelled, which matters because they are heavy. The gas Toro and Ariens models both list six forward speeds and two reverse.

Battery two-stage machines now exist. EGO says the SNT2425 can clear up to an 18-car driveway covered with 8 inches of snow on a single charge. Ryobi lists up to 30 minutes of runtime for the RY408150 on its two included batteries. On a very long driveway or after a big storm, a gas engine refueled outdoors avoids that limit.

Gas, corded or battery: which power source?

• Corded electric: light and simple, limited by cord length and by lighter snow.
• Battery: no fuel and no cord. Check the maker’s runtime or driveway-size claim against your own driveway, and budget for a second battery if needed.
• Gas: longest run time and the widest two-stage models, but it brings carbon monoxide and fuel handling (see the safety section below).

For outages, a snow blower is only part of the plan. Our winter storm preparedness guide covers the rest of the gear, from weather radios to the car kit.

How do you use a snow blower safely?

Every statement in this section comes from the CPSC’s Snow Thrower Safety alert. CPSC has received reports of injuries including finger amputations, and most happen when people try to clear the discharge chute or the auger by hand.

Carbon monoxide from gas engines

CPSC reports that people have died from carbon monoxide poisoning after leaving a snow thrower’s engine running in an enclosed space. Its rule is simple: never leave the machine running in an enclosed area.

Refueling

CPSC says to add fuel to the tank outdoors before starting the machine, and never to add gasoline to a running or hot engine. Keep the gasoline can capped. Store gasoline out of the house and away from ignition sources.

Electric models

CPSC advises owners of electric snow throwers to be aware of where the power cord is at all times.

Is a snow blower easier on the heart than shoveling?

The American Heart Association says so. In a January 2024 AHA release, Barry Franklin, Ph.D., lead author of the association’s 2020 scientific statement on exercise-related cardiovascular events, said a snow blower raises the heart rate to around 120, compared with around 170 while shoveling. A January 2025 AHA release adds that snow blower users should still proceed with caution.

The AHA says people who have had a heart attack, a stroke, bypass surgery or coronary angioplasty should not be shoveling snow in any conditions. If you have a heart condition, ask your doctor before any snow clearing, including with a machine. Our snow shovel guide covers the AHA’s warning signs and pushers that avoid lifting.

What else do you need after the driveway is clear?

A snow blower moves snow but leaves a thin layer that can freeze. Our guide to ice melt vs rock salt compares the chemicals by working temperature and by what each does to concrete, pets and plants. Snow on the roof is a separate job: see roof rakes and ice dams for clearing it from the ground.
