"Ever try to spot-clean your car's interior or a carpeted floor in your home with an old Dustbuster? It couldn't suck up a straw wrapper, let alone real dirt. But times have changed: Thanks to high-wattage motors and smaller, more powerful batteries, the latest cordless, rechargeable vacuums clean almost as well as their plugged-in counterparts. Plus, they're still able to sneak into the hard-to-reach crevices. We attacked several apartments' worth of dirt and pet hair, spending time with each vacuum over a few weeks. During all tests, a decibel meter read each machine's volume, and battery life was recorded."^^<http://www.w3.org/2001/XMLSchema#string>
