The Gtech AirRam ditches the cord (pictures)

The Gtech AirRam features a Lithium-ion battery that gives you approximately 40 minutes of vacuuming on a 4-hour charge.

While the AirRam operates cordlessly, you do need to plug it in to charge. Next to this port is the port for the data bridge, which connects the vacuum via USB to your computer. There, it syncs with the AirRam software to give you such information energy savings, battery diagnostics, or estimated calories burned while vacuuming.

With only one button, the AirRam is effortlessly easy to use.

Like most bagless vacuums, the AirRam includes a washable filter.

The filter resides in the dustbin lid. You can remove the lid by itself to wash the filters or the lid and bin together to empty debris into the trash.

Four indicator lights tell you the level of battery charge, both while the vacuum is charging and in use.
