Our Verdict

Miele Triflex HX1

LG CordZero A9 [A916, A916BM]

The Miele Triflex HX1 and LG CordZero A9 each have advantages, meaning one might be a better fit for you, depending on your needs. The Miele is better built, easier to maintain, incurs lower recurring costs, and performs slightly better on bare floors and low-pile carpets. It also has an automatic surface-type adjustment feature. Conversely, the LG has a larger dustbin and better performance on high-pile carpets. It can also be bundled with a second battery, giving it a longer overall runtime.
