The K3 is the carpet specialist in this group. Its ET-1 powerhead has its own brush motor, so the roller keeps turning at a steady speed whatever the pile does to it, and a 1250 W body motor supplies the suction behind it. A 37 foot operating radius is quoted from a 25 foot cord and a long hose, which means fewer plug changes across a big floor.
The head matters most. A powered brush lifts matted fibres and loosens embedded grit in a way that suction-only heads cannot, and it adjusts to different pile heights. Compared with the Kenmore 600, the K3 feels more like a tool than an appliance, and its seven-year motor and component warranty is the clearest sign of a build meant to last.
It is heavier and more expensive than the household machines here. Change the bag before it is full, clear hair from the roller each few weeks and keep the filters on schedule. The ET-1 shuts off the brush if it jams, a sensible protection that saves belts and fingers.
