Best 20 Inch Snow Blower Buying Guide

Power Source: Corded vs. Cordless vs. Gas

Your choice of power source determines runtime, maintenance, and convenience. Corded electric models offer unlimited run time but require a nearby outlet and an extension cord rated for cold weather.

Cordless battery-powered snow blowers provide freedom of movement and quieter operation, though you may need spare batteries for larger areas. Gas models are rare in the 20-inch class; most 20-inch units are electric.

If you prioritize zero emissions and low noise, a cordless battery snow blower is worth considering. For consistent power without battery anxiety, a corded electric model may be more practical.

When comparing options, think about your driveway length and typical snowfall. For shorter paths and light snow, a cordless unit with two batteries can handle the job. For longer driveways or frequent heavy snow, a corded machine eliminates downtime.

Our corded electric snow blower guide covers top performers in that category, and our cordless snow blower roundup highlights the best battery-powered picks.

Clearing Width and Intake Height

A 20-inch clearing width is ideal for single-pass clearing on standard walkways and small driveways. Most 20-inch snow blowers have an intake height of 10 to 13 inches, which handles moderate snowfall up to about 12 inches.

For deeper snow, you may need to take multiple passes or look at a wider model. The snow depth capacity guide explains how different designs cope with heavy accumulation.

If your area gets frequent lake-effect dumps, a two-stage snow blower might be a better fit, though it usually comes with a larger clearing width.

Keep in mind that wider intake does not always mean faster clearing if the machine lacks enough power to throw snow far. The best 20 inch snow blower balances width with motor strength and auger design.

Auger Material and Design

The auger is the heart of a single-stage snow blower. Steel augers are more durable and can handle icy, packed snow, while rubber-tipped augers are gentler on paved surfaces but may wear faster on gravel.

Many 20-inch models use a steel auger with a rubber edge to combine toughness with surface protection. If you have a gravel driveway, look for an adjustable scraper blade or a model specifically designed to minimize stone throwing.

Some cordless models feature a brushless motor paired with a steel auger for efficient power delivery. Check the auger width relative to the housing; a full-width auger improves snow intake and reduces clogging.

Throw Distance and Chute Control

Throw distance matters when you need to clear a path without dumping snow back onto the driveway. Most 20-inch electric snow blowers throw snow 20 to 30 feet, which is sufficient for typical residential use.

Look for a model with a rotating chute (often 180 or 200 degrees) and a deflector that lets you adjust the trajectory. Remote chute control is a premium feature on some cordless models, allowing you to change direction without stopping.

Dual LED lights are becoming standard on many 20-inch snow blowers, which is a real help when clearing snow early in the morning or after sunset. Good illumination also improves safety by letting you see obstacles hidden under the snow.

Build Quality and Portability

A 20-inch snow blower should be light enough to maneuver but sturdy enough to handle repeated use. Look for models with a robust steel frame, reinforced handles, and large wheels (at least 7 inches) for better rolling over uneven surfaces.

Weight typically ranges from 30 to 50 pounds for corded units and up to 60 pounds for cordless models with batteries. If you have to store the machine in a tight space, consider foldable handles or a compact design.

Our homeowner buying guide covers additional factors like storage and maintenance.

Also evaluate the warranty. Most reputable brands offer two to five years of coverage on the motor and drivetrain. A longer warranty often signals confidence in build quality.

Frequently Asked Questions

Can a 20-inch snow blower handle heavy wet snow?

Most 20-inch electric snow blowers are designed for moderate snow up to about 12 inches. Heavy, wet snow can strain a single-stage auger and reduce throw distance.

If you regularly face wet snow, choose a model with a high-torque motor and a steel auger. For extreme conditions, a tracked snow blower or two-stage machine may be more appropriate.

How long does a battery last on a cordless 20-inch snow blower?

Runtime depends on battery capacity and snow conditions. With two 4.0Ah batteries, you can typically clear a standard two-car driveway (about 800 sq ft) on a single charge. Cold temperatures reduce battery efficiency, so storing batteries indoors before use helps.

Always check the manufacturer’s stated runtime and consider buying an extra battery if your driveway is large. Our battery snow blower guide provides more details.

Do I need a special extension cord for a corded snow blower?

Yes, use a heavy-duty outdoor extension cord rated for the amperage of your snow blower (usually 14 or 12 gauge). A 50-foot cord is sufficient for most driveways; longer runs may require a thicker gauge to prevent voltage drop.

Keep the cord away from the auger and use a cord retainer on the handle to avoid accidental disconnection.

Can I use a 20-inch snow blower on gravel?

Yes, but you need to take precautions. Set the scraper blade higher to avoid picking up stones, and choose a model with a rubber-tipped auger if possible. Some manufacturers offer a gravel kit.

For detailed advice, see our article on using a snow blower on gravel.

What maintenance does a 20-inch electric snow blower require?

Electric snow blowers need less maintenance than gas models, but regular care extends their life. After each use, clear snow and ice from the auger and chute. Lubricate moving parts with silicone spray, and inspect the power cord for damage.

Store the machine in a dry place. For cordless models, remove batteries and store them at room temperature. Our maintenance guide covers seasonal tips.

Are 20-inch snow blowers easy to store?

Most 20-inch snow blowers are compact enough to fit in a garage corner or shed. Many corded models have foldable handles to reduce vertical storage space. Cordless models with batteries add a bit of weight but are still manageable.

If space is tight, look for a model with a collapsible handle. For more storage ideas, check our snow blower accessories guide.
