Gtech AirRAM Cordless Vacuum Cleaner

The Gtech AirRAM High-power Cordless Vacuum Cleaner features a novel design that places the collection chamber behind the brush bar (the debris is packed into an easy-to-dump brick), letting it save energy typically spent shuttling dirt up long tubes. The rethink gives the battery-operated cleaner a full 40 minutes of continuous cleaning power, enough for a large home. [$350; greytechnology.com]
