Whether you're rustling up oak leaves in fall or magnolia petals in spring, leaf blowers with a built-in vacuum mode would seem to offer a one-tool solution to blowing and bagging. But in a case of more may be less, many owners end up never using the vacuum function.
"The vacuum on most leaf blowers isn't really designed to deal with a huge pile of leaves," explains Dave Trezza, CR's leaf blower testing expert. "And it's rare that we see a leaf blower live up to its promised mulching ratio."
Many blower vacs promise to shred leaves and reduce their volume by a ratio of 12:1 or 16:1. Of course, Consumer Reports doesn't take manufacturers' word for it. We measured. And we found that many tools shred leaves only down to a 3:1 or 4:1 ratio.
That gets to the biggest limitation of blower vacs: They collect only a small quantity of leaves before you have to empty the bag—a messy task.
That may be why some manufacturers have started to drop leaf blower vacuum functions entirely.
But sometimes more can be just right. If you have a small yard and are diligent about keeping up with leaves as they fall, or if you want to surgically suck up leaves from around bushes and flower beds, the vacuum mode on your leaf blower can save you time and effort.
None of the battery-powered blowers we tested offer a vacuum function, and you won't find the feature on the most powerful type of blowers, wheeled or backpack models. It’s usually available only on gas and corded handheld units.
How to Use a Leaf Blower Vacuum
To convert your machine from leaf blower to leaf vacuum, in most cases you'll have to switch the tube to the opposite side of the fan. Sometimes that requires special tools, which can be cumbersome.
But you'll want to start in leaf blower mode, and corral the bulk of your leaves into a large pile. (For tips, check out CR's experts' clever strategies for dealing with leaves.) Then switch to the vacuum. Use it to suck up any stragglers and to work around bushes and flower beds, where a blower could damage plants or send soil and mulch flying. When you're finished, be sure to empty the bag and flip it inside out to clean it thoroughly. Lingering leaves, particularly if they’re wet, will break down and start to smell funky.
The vacuum is also helpful for keeping porches, patios, and decks tidy as trees shed their last leaves of the season. Some models (and aftermarket attachments) have curved nozzles specifically designed for blowing or sucking leaves out of your gutters. Just make sure to follow safety guidelines if you’re working from a ladder.
And don’t rush to store your tool at the first sign of winter, either. The blower function can be used to clear a light dusting of snow from decks, patios, and walkways, buying you a little time before you have to break out your snow blower.
