Best 21 Inch Snow Blowers (2026)

The SNT2100 is the strongest cordless 21 inch blower in this group because it ships with two 7.5Ah batteries and uses Peak Power, a system that combines two packs to feed a brushless motor. The steel auger cuts through packed snow and the crust left by a plow.

EGO claims it clears about a sixteen-car driveway of eight inches of snow on a single charge, a figure that depends on snow density. The 40 foot throw distance and remote chute control from the handle let you direct snow without stopping. Compared with the SNT2122, which ships with two 4.0Ah packs, it carries almost double the stored energy.

Batteries are shared across the EGO family, and the machine needs essentially no seasonal engine upkeep. Charge the packs before storage, keep them indoors in deep cold, and clear packed snow from the chute.

This EGO model is built around auger-propelled design, where the auger itself pulls the machine across the pavement. That makes it lighter and simpler than wheel-driven systems and is how single-stage blowers scrape down to bare pavement.

The 45 foot claimed throw is the longest in this group and clears the SNT2100's 40 foot claim. It carries the same two 7.5Ah batteries and claimed 16-car capacity. The tradeoff of auger propulsion is that it can skip on rough or gravel surfaces and is not a substitute for powered wheels on a steep drive.

It shares batteries with the EGO line. Keep the auger clear and store the packs indoors in deep cold.

The SNT2120 is sold bare, which makes sense for people who already own EGO 56V batteries. It uses Peak Power to combine two ARC packs, and a steel auger cuts packed snow and ice.

Variable auger speed control lets you slow the auger for light snow to save battery, or speed it up for heavy drifts. The 13 inch clearing depth is comparable to corded units but backed by battery power. With two recommended 6.0Ah batteries, EGO claims a 14-car driveway.

Because you supply the batteries, the price is lower if you already own them. Charge before storage and keep the chute clear.

The SNT2122 is the entry kit for the same machine as the SNT2120, with two 4.0Ah batteries and a 320 watt charger included. It claims a 10-car driveway of eight inch snow, below the 14 to 16 cars of the larger battery kits.

The same steel auger, variable speed control and 180 degree chute apply. For a one or two car driveway and short walks, the smaller batteries are enough, and a faster charger helps between passes.

If your driveway is bigger, the larger battery kits are better. It shares the EGO battery family.

The SENIX is a corded blower with an 1,800 watt, 15 amp motor. Corded machines never run out of power while plugged in, and they avoid cold-weather battery fade, which is a real advantage.

It clears a 21 inch by 12 inch path and moves up to 880 pounds of snow per minute, with a 33 foot throw. That is stronger than the PowerSmart's 30 foot throw in distance and slightly below its 1,020 lb/min rating. A 15 amp load needs a heavy extension cord of 14 gauge or thicker.

The tradeoff is cord management and range, which limits it to driveways within about 100 feet of an outlet. Never cut or run over the cord.

PowerSmart rates its corded blower at up to 1,020 pounds per minute, the highest corded figure in this lineup. The clearing depth is 6 inches, though, which is half the SENIX's 12 inches, so it is built for light snow more than deep drifts.

An LED light helps in dark winter mornings, and the 180 degree chute directs snow. A reinforced auger handles routine accumulations. It is a good fit for patios, decks and short drives.

As with all corded units, a heavy extension cord and careful cord handling are essential.

AMERISUN lists a 12.5 inch clearing depth, slightly deeper than the SENIX's 12 inches, with a 15 amp motor at 2,100 RPM. An adjustable deflector helps reduce blowback onto cleared areas.

The throw distance is 30 feet, shorter than the SENIX's 33 feet, and an LED headlight helps in the dark. It suits residential driveways and walks near an outlet.

It is a corded unit, so cord handling and range apply. Keep the cord clear of the auger.
