Kirby vacuums have changed over the life of the company. The models have all looked similar, though, and you determine the model number in the same way. You will need the model number to obtain certain parts, such as the headlight, should they need replacing. Do not be concerned if you are not asked for the model number for items such as vacuum bags, as these are interchangeable between models.
Locate the front of your Kirby vacuum's handle. If the handle is missing or the plastic has broken off, locate the front of the vacuum-bag holder.
Find the Kirby logo on either the handle or bag holder. The logo is always on the front of the vacuum.
Read the model name located either underneath or above the Kirby logo.
