Bagless vacuum cleaners are by far the most popular choice. Contrary to popular belief however, a bagless vacuum cleaner will not necessarily perform better than a bagged vacuum. A bagged vacuum can also be the best choice if you or anyone in the household is asthmatic or suffers with a dust allergy. Before you buy, knowing the advantages and disadvantages of bag vs bagless vacuum cleaners can ensure you choose a vacuum best for you.
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.
Watts are a means of measuring the amount of power that's put into the motor. However, because the output power or suction you receive at the end of the hose depends on the vacuum's design and efficiency, air watts, which measure the output power and suction, are considered a better means of comparison for vacuum cleaners. Remember however, a clogged filter will quickly impair ait watt performance.
