Dyson V8 vs V12 Detect Slim

The Dyson V12 Detect Slim is better than the Dyson V8. The V12 offers vastly improved battery performance, with a longer runtime and a much shorter recharge time. It also performs better on bare floors and is more effective in dealing with debris in cracks and crevices when used with its Laser Slim floorhead. It weighs a little less, making it even easier to maneuver. The V12 also has an automatic power adjustment feature, which allows it to increase its suction mode on carpeting or when it detects a significant concentration of debris. That said, the V8 has a larger dirt compartment that's over twice the capacity.
