Active base plate
The cleaner heads on most upright vacuums need to be manually adjusted for different floor types. If this isn’t done, a gap is created between the cleaner head and the floor, and suction is lost.
The latest Dyson upright vacuums have an active base plate that self-adjusts across every floor type. It maintains close contact with the floor at all times, automatically raising and lowering. Suction isn’t wasted – it’s sealed in.
