Convenient and full of features, the Dirt Devil Vision upright vacuum is a heavy-duty cleaning machine for the whole house. Suitable for bare floors, above-floor tasks, and multiple heights of carpet, the 12-amp machine features a dial-adjusted floor nozzle with a triple-row agitator brush roll for cleaning and grooming carpet fibers. Its dirt collection is bagless, using a generous, transparent dust cup instead of cumbersome bags. When dirt and debris pile up inside, the cup simply pops off the vacuum to be emptied--this task made simpler by its lid and built-in handle. An internal pleated HEPA filter traps 100 percent of ragweed and pollen as well as the majority of dust, irritants, and pet dander. The filter taps clean for regular maintenance and typically lasts about a year before it needs replacing. Though the Vision's bagless construction is somewhat bulky for fitting under furniture, its onboard accessory set counteracts that shortcoming. Designed for instant use, the onboard hose is substantial and stretchy, providing powerful suction for dusting shelves, snagging cobwebs, and cleaning in tight spots. The standard onboard attachments include a dusting brush, a crevice tool, and an extra wand. The more high-tech attachment is the motorized Turbo Tool, which has its own brush roll, making it perfect for upholstery and carpeted stairs. Dirt Devil equips the Vision with other welcome extras, like quick-release power cord hooks, a carrying handle, and a bright headlight. The vacuum carries an especially generous warranty--three years on the parts and six years on the motor. --Emily Bedard
