The Gtech AirRam Mk1 DM001 AR02 is a lightweight, 3.5kg cordless upright vacuum designed for easy, wire-free cleaning on carpets and hard floors. For an idea, of the battery condition, I ran this cleaner from full to empty battery - not on a carpet, but just the suction and beater bar running and managed to get 59mins 19secs unloaded (will reduce on a cleaning surface, but better than I expected for a 5 year old battery).
