Decide on a Type of Vacuum
If you're not sure what type of vacuum to get, talk to a vacuum professional and ask for advice. Depending on the type of floor coverings and other features of your home, they will be able to help you decide if an upright or canster type will best suit your needs. There are also other choices such as lighter weight vacuums and specialty vacuums that may be possibilities. In the end, it's your choice as to what type of vacuum you think will best work for you
Once you've decided on which type of vacuum is best for your needs, your next move should be to review the type of options and features available for that type of vacuum. For example, if you're considering an upright, would you like on-board tools? Is it important that the machine have a feature to turn off the brushroll when it's being used on hard floors? What about machine weight? Is one motor fine, or is the new "tandem air" two motor system best for you? Is the filtration technology offered sufficient? Is quiet running important to you? What is the life of the vacuum? These are all things to consider.
