SENIX 40V 21-Inch Cordless Snow Blower vs Greenworks 80V 20" Brushless Cordless Snow Blower

How they differ in real use

Built from our battery snow blowers for small driveways scoring, each product's published specifications, and verified owner feedback — not hands-on testing.

Both the SENIX 40V 21-Inch Cordless Snow Blower and the Greenworks 80V 20" Brushless Cordless Snow Blower made our Top 5 Battery Snow Blowers for Small Driveways, at #2 (best value) and #5. The same 21-inch width and variable-speed steel auger as the EGO for roughly half its Amazon price, in a machine that weighs about 30 lb instead of 50 lb. SENIX lists a 33 ft throw, an adjustable 8 to 12-inch clearing depth and a 5-year tool, 3-year battery warranty, the longest coverage here. It ranks below the EGO because its throw is shorter, its 40V battery line runs few other tools, and it has far fewer owner reviews. Against the 18-inch Westinghouse it clears 3 more inches per pass with a longer throw and a steel auger. The most owner-reviewed machine here, with more than 4,000 Amazon ratings, a 20-inch path and a light 33 lb build, and a good buy for anyone who already owns Greenworks 80V batteries. As a complete kit it lands last: it ships with a single 2.0Ah battery, the smallest in this list, so it runs out well before the two-battery Snow Joe and Westinghouse kits on a full driveway, its listed throw of about 20 to 22 ft is among the shortest, and Greenworks does not list a steel auger. It also costs more than the SENIX, which clears a wider path with a steel auger and two batteries.

We score battery snow blowers for small driveways on Clearing Power (25%), Battery Kit & Runtime (20%), Auger & Build (15%), Handling & Storage (15%), Battery Ecosystem (10%) and Value (15%). On that basis the SENIX 40V 21-Inch Cordless Snow Blower totals 8.5 out of 10 and the Greenworks 80V 20" Brushless Cordless Snow Blower 7.2. The widest gap is Battery Kit & Runtime, where the SENIX 40V 21-Inch Cordless Snow Blower scores 8.4 against 6 for the Greenworks 80V 20" Brushless Cordless Snow Blower: number and capacity of the batteries included in the box, charger speed, and the manufacturer's rated runtime per charge. Clearing Power also separates them: 8.6 for the SENIX 40V 21-Inch Cordless Snow Blower versus 7.2 for the Greenworks 80V 20" Brushless Cordless Snow Blower. The Greenworks 80V 20" Brushless Cordless Snow Blower claws back ground on Battery Ecosystem.
