Although many people aren't aware, upright and cylinder vacuum cleaners were originally designed for different purposes. Upright vacuum cleaners were designed for vacuuming carpeted floors in cooler climates (such as the UK) while cylinder vacuum cleaners were designed for vacuuming hard floors in hotter climates (such as Spain). As a result, not all cylinder vacuum cleaners come with powerful rotating brushes.
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.
If you suffer with asthma or a dust allergy, the filtration system should be an important factor to determining which vacuum cleaner you'll buy. This is because the filtration system will determine the size and number of dust particles that'll be in the air when it is exhausted out of the vacuum.
