Power

• DustBusters are powered by electricity and batteries. Batteries must be charged or else the DustBuster will not work without being plugged into an electrical outlet. Accordingly, it is important to consider how long the battery life of a dust buster can last for. Another thing to look at is how long the electrical cord is.
  
  

Attachments

• Attachments, such as special nozzles for reaching small spaces, can make a difference. Some attachments may be appealing depending on what the user wishes to primarily use the DustBuster for.
  
  

Brand and Price

• The price of a DustBuster is heavily impacted by the manufacturing brand. Name brands are going to be more expensive than the generic lines, but consumers may also be paying for a higher-quality product. Reading product reviews is an effective way to get a sense for other people's experiences with a particular line of DustBuster.
