Years ago, we didn't have the luxury of being able to decide whether we wanted a lightweight vacuum cleaner. A vacuum cleaner was a vacuum cleaner so the possibility of a lightweight vacuum cleaner was inconceivable.
These days however, lightweight vacuum cleaners are immensely popular and there are several reasons behind this surging demand.
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.
A high wattage (input power) doesn't always mean better suction because the amount of this power that's turned into air watts (suction or output power) depends to some extent on the vacuum's design and efficiency.
