The ideal material for a vacuum is stainless steel. Stainless steel vacuums are preferred because they are more durable and longer-lasting than other types of vacuums, like plastic.
Stainless steel vacuums cost more than other types of vacuums. The cheapest type of vacuum is a plastic vacuum but it's more likely to wear out faster. The frequency of use of the vacuum also affects how long it lasts. Larger households with bigger cleaning needs may need a higher-strength vacuum with more capacity.
People who are concerned about environmental health may want to choose a vacuum with a high-efficiency particulate absorbing (HEPA) filter. HEPA vacuums work similarly to a normal vacuum but as the vacuum sucks air in through the bottom, it runs it through a filter to catch airborne particles.
