Currently, the newest Shark APEX UpLight on offer is the LZ600-series. There are three models in total in this series: the LZ600, LZ601, and LZ602. They all share the same performance level, the same design, and are roughly priced the same. The key difference between the three models is the coloring and the accessories. The LZ600 comes in a purplish color, called “Magenta”. The LZ601 is painted in a vibrant, azure blue called “Forest Mist Blue”. And lastly, the LZ602 has an orange-ish coloring that Shark termed “Terracotta”. Included accessories are different from one model to another. With the LZ600, you get an 8-inch crevice tool, a pet multi-tool, and an accessory holder to store both of these accessory pieces right on your vacuum. LZ601 has a pet multi-tool and a duster crevice tool. You will also get the accessory holder. As for the LZ602, you get a motorized pet tool, a bristle brush, and a duster crevice tool. The selection of accessories seems to be the most expansive on the LZ602, which is the reason why it is the most popular model among the three.
