Ease of use

This Snow Joe model requires little work to be put into it, as it moves on its own and does not require the customer to push it. It starts with a push button on the handle which instantly starts the snow thrower. The 13.5 amp electrical motor does not require any maintenance, yet is very powerful, as it can move up to 650 pounds of snow per minute. The adjustable chute is another very useful feature, as it allows the customer to control the exact direction where the snow will fall. According to the snow blower reviews, this Snow Joe is very small in size, but does a great job with wet snow. It cannot, however, handle 10 inches of snow, only about 6 inches. The headlight is very useful during the night but, as some reviewers pointed out, but it does tend to get covered in snow, so after a while of using it, the customer has to clean it.


In 6 inches of snow fall, this Snow Joe model, although small, works perfectly. However on thicker layers of snow of up to 10 inches, it tends to choke. The 13.5 amp electrical motor works perfectly in any type of weather and, according to some reviewers, it throws the snow up to 20 feet away. The adjustable chute is a bonus, since this way, the customer is able to manually direct the flow of the snow. Some electric snow blower reviews say that customers loved the light weight of this top rated snow blower, while others complained that since it is weights so little, it requires several passes to clean up ice. Other useful features include a safety button to prevent accidental starting of the snow blower and compact wheels for a better and more efficient maneuvering of the machine.


Some reviewers said that this particular Snow Joe model can last up to a few years. The Snow Joe offers those that buy this model the standard 2 year warranty.

Frequently Asked Questions (FAQs)

How loud is my Snow Joe Ultra SJ621?

Your Snow Joe Ultra SJ621 has a decibel rating of 100 dB.

What is the best way to clear a path with the Snow Joe Ultra SJ621?

Start your clearing path near the electric outlet and work outward, throwing snow in a back and forth motion. You should push the snow thrower gently and evenly in accordance with the unit's throw rate. To clear in the opposite direction, step over the cord and pivot the snow thrower on its wheels. Make sure to overlap clearing paths and to throw the snow in the same direction as the wind.

What depths will my Snow Joe SJ621 clear?

The Snow Joe SJ621 Plus snow shovel is the perfect first snow thrower in light snowfall regions that typically receive 3-6 inches of snow per storm. It is also a great adjunct tool in heavier snowfall regions for quick clean-ups on steps, decks, patios, and sidewalks. Unlike larger snow throwers, the Snow Joe Plus is compact and easy to maneuver in tight spaces. You also don't need a large garage or basement for storage--the Snow Joe Plus fits easily into a closet. When dealing with heavier snowfall (6-12 inches) over a larger surface area, the first line of defense would be the Snow Joe Ultra snow thrower. Ideal for clearing large driveways and walkways, the Snow Joe Ultra series features powerful maximum-amperage motors that can move up to 800 pounds of snow per minute and clear over 2500 square feet per hour. Its adjustable chute also allows you to effectively direct the snow so you can clear paths easily.

What safety precautions should I take when operating the Snow Joe Ultra SJ621?

When operating the Snow Joe Ultra SJ621, make sure to use a UL rated extension cord indicated for outdoor, all-weather use. To prevent the extension cord from disconnecting during use, use the onboard cord restraint clip and/or make a loop and knot the female end of the extension cord to the male plug of the unit's power cord. Take precaution not to run the blades of the unit over the extension cord. If the cord is damaged, replace immediately. Foreign objects, such as rocks, broken glass, nails, wire or string, can be picked up and thrown by the snow thrower, causing serious personal injury. Make sure to remove all foreign objects from the area to be plowed before operating the snow thrower. Never direct the snow discharge chute at the operator, at bystanders, at vehicles or at nearby windows. The discharged snow and foreign objects accidentally picked up by the snow thrower can cause serious damage and personal injury. Always orient the discharge chute in the opposite direction from where you, bystanders, surrounding vehicles, or windows are located. Refer to the Snow Joe Ultra user manual in the Product Support section of our website, or in the Downloads section of the product listing, for additional safety instructions.

I've pressed the switch button, then squeezed the handle, but my Snow Joe Ultra does not power on. What should I do?

As an added safety feature, the machine will only power on when pressing the safety switch button and squeezing the handle consecutively. Use your finger on one hand to press the safety switch button and use your other hand to squeeze the handle. Once your machine starts, you may then release your finger on the safety switch button, and grip the handle with both hands to maintain operation. If you wish to power off, release your grip on the handle.

Where and when should I use my Snow Joe Ultra SJ621?

The Snow Joe Ultra SJ621 electric snow thrower is designed to tackle heavy snowfall (6-12 inches deep) on large driveways and walkways. It is intended for use on paved surfaces. When working on pebbles, gravel, or unpaved surfaces, push down on the handle of the unit to raise the scraper at the base of the unit above the pebbles or gravel. This will avoid throwing loose surface material along with the snow. As a general rule, it is best to remove fresh snow that has just fallen before it becomes packed down and hardened.

Does the Snow Joe Ultra SJ621 require assembly?

The Snow Joe Ultra SJ621 requires minimal assembly. Most of the assembly has already been completed at the factory. The operator simply has to assemble the upper, middle, and lower frames of the unit, engage the discharge chute, and install the chute crank.

Does the Snow Joe Ultra SJ621 run on gas?

The Snow Joe Ultra SJ621 is electrically powered, making it effortless to start and maintain. No gas, oil, or tune-ups are necessary.
