Handheld Vacuums and Electric Dusters

Vacuum or air duster: they solve different problems

A handheld vacuum pulls debris into a cup or bag, which suits crumbs, pet hair and car interiors. A cordless air duster or electric duster blows a fast stream of air from a high-speed fan, rated in thousands of RPM, to clear dust from keyboards, PC fans and vents. Some products are sold under both names, so read what the product actually does: if you want to remove dust rather than scatter it, you want suction and a filter.

Volts, watts and the dust cup on a handheld

Corded handhelds, which run on 120 V and list watts, give steady suction for as long as you need. Cordless ones list battery voltage, such as 7.4 V or 10.8 V, and a higher voltage generally means stronger suction but also a heavier pack. Bagless models have a cup and filter you tap clean or wash; bagged ones need bags matched to the model. Check weight too, since a handheld you can hold overhead for a minute is the one you will use.

Questions about Handheld Vacuums and Electric Dusters

Is a handheld vacuum strong enough for a car?

Yes for crumbs, sand and pet hair on seats and mats, provided it has a narrow crevice tool. Corded models keep full power; cordless ones suit quick jobs. Deep carpet dirt and wet spills are better handled by a stronger vacuum or a wet-dry model.

Can I use an electric duster on a computer?

Electric dusters made for electronics are intended for that job and avoid the cold propellant of canned air. Even so, power down and unplug the computer, hold fan blades still while you blow, and keep the nozzle a short distance from components.

How long does a cordless handheld run?

Runtime depends on battery capacity, the power mode and how clogged the filter is, and ratings are usually the best case. Expect shorter runs on a strong setting, and charge it fully before long jobs. Replace a pack that no longer holds charge.
