An upright vacuum cleaner has a vertical dustbin. In contrast, a cylinder vacuum cleaner has an almost horizontally positioned dustbin. Unknown to some, these two styles of vacuum cleaners offer both advantages and disadvantages. You should base your overall choice on the area you will be vacuuming and your individual preferences.
Having a vacuum that's specially designed for pet hair is essential for keeping the house clean and fresh, and ensuring that when you vacuum, the pet hairs and allergens are actually being picked up.
The capacity of the vacuum cleaner's dust bin or bag will essentially determine how often you'll need to empty it. If you have a large house and you don't want to be going back and forth the bin, it's worth investing in a vacuum cleaner with a bigger capacity. That said, if you have trouble lifting or manoeuvring a vacuum cleaner, bear in mind that the bigger the vacuum cleaner's capacity, the heavier it'll be.
