While searching for a new vacuum cleaner recently, I stumpled upon this website. I already knew which type of vacuum cleaner I needed, which is why I could easily navigate to the given category and pick one of the highest rated models.
However, I did have some specific needs, e.g. I needed an allergy friendly vacuum for pet hair, and the website didn't have any recommendations for certain needs. That would definitely be help, though.
Overall a nice website with some good-to-know facts about different vacuum cleaners, but still room for some improvement.
