Hello Acerone:
You may want to check out the latest in cordless Dirt Devil and HOOVER products called AccuCharge. One of the problems I noted with my HOOVER Slider after 2 years is the run time is halved. AccuCharge technology has a sensor that cuts off the charging when it senses a full charge. This avoids overcharging and overheating which diminish the products' run time over time. Also earns the Energy Star for appliance usage. Several threads are here on the new products and technology. And of course, the Web Sites with te products.
