A common problem with conventional cordless vacuum cleaners is that their batteries eventually wear out, forcing you to replace the battery or replace the vacuum. Neither is a fun solution. Many cordless vacuums rely on a Ni-Cad battery system that is continuously pumped full of juice when it’s plugged into the wall. Even when the battery is fully charged, more power keeps seeping in, heating and damaging the battery cells. Not only does this process waste energy, but it gradually shortens the run time of your vacuum per charge.
Dirt Devil developed a new charging technology called Accucharge that is supposed to save considerable energy and preserve the vacuum cleaner’s battery life. With Accucharge, the smart charger constantly monitors the battery’s power level. Once the battery is fully powered, the charger slows down its energy input to a trickle—just enough energy to keep the battery full of juice. The benefits are great. Not only are Accucharge Dirt Devils Energy Star compliant, but they take less time to charge and maintain their vacuuming power longer per charge.
With this kind of smart technology, we may have a solution to the common hassles of using a cordless vacuum. Finally we can get the performance of a corded vacuum without worrying about wasting energy or wearing out a battery.
