The Black+Decker PD1420LP has a standard washable filter.
Most brands are also more interested in promoting.rather than cleaning performance..
In an attempt to make things easier, some vacuum cleaner manufacturers list “Air Watts” as part of their vacuum specifications..Unlike regular watts, this metric is meant to measure the vacuum’s suction power.But how is it calculated?
And is it a useful rating…or just another marketing gimmick?Let’s find out!.
What Exactly Are Air Watts in Vacuums?.
Air watts (AW) is a way to measure the suction power (or output) of a vacuum cleaner.. We’ll get into the formula for Air Watts later, but the calculation involves both.When you turn the vacuum on it will start up in medium power, which we think is a good combo for battery life and cleaning performance.. Samsung says it’ll take 3.5 hours to fully charge a battery, but it can be up to an hour less than this.
This is quicker than many cordless vacuums, despite the relatively long run-time..If you need more battery run-time, there’s the option of buying additional batteries – but they’re expensive.
It’s great to have the.of an extra battery though, as some vacuums don’t allow you to remove the battery.
