The LG CordZero A9 Ultimate is a cordless stick/handheld vacuum with two swappable batteries so you can vacuum with one while the other one charges. Unlike the barebones LG CordZero A9, which only comes with one universal nozzle for different surfaces, this model comes with two additional nozzles better-suited for bare floors and picking up pet hair. However, it can be troublesome to adjust this vacuum to different surface types as you have to change out its nozzle. It also has demanding maintenance needs. Still, it offers outstanding performance on bare floors and its handheld design is well-suited for cleaning hard-to-reach areas.
