Ideally, service vacuums every 12-18 months. With time, dirt and lint can gather on the vacuum's motor bearings, which can slow the roll of its brush and place undue strain on its motor. The brush may also wear out with time, and this can reduce the vacuum's cleaning ability by as much as 50 percent. Dirty motor bearings can also cause the vacuum's engine to overheat.
Do vacuums with higher amperage clean better?
Vacuums with higher amperage don't necessarily provide better cleaning. A vacuum's amperage is the amount of electric current that flows through the unit. While high amperage can favorably affect performance, other factors play even more important roles. Air flow is a key variable to consider, since it will give you an idea of how well the vacuum handles suction. Other important factors include filtration, hose quality, and nozzle design.
What is the difference between a canister and an upright vacuum?
Upright vacuums stand vertical, and include the motor and suction head in the same unit. With canister vacuums, the cleaning nozzle is located at the end of a wand that connects to a wheeled canister via a hose. The canister holds the unit's engine, filter, and dust bags, and it needs to be dragged by the user when the vacuum is being operated. Upright vacuum cleaners tend to be less expensive than canister vacuums, but canister models tend to be more maneuverable.
What is a stick vacuum cleaner?
A stick vacuum cleaner has its dustbin container incorporated within the stick that connects to the nozzle. This gives it a cleaner look than other types of vacuum cleaners, and it also reduces its weight. Stick vacuum cleaners require minimal storage space, so they're a good choice for apartment dwellers. However, they typically have less cleaning power than other types of vacuums.
Do vacuum cleaner stores specialize in specific brands?
Vacuum cleaner stores usually specialize in specific brands. Large chain stores often carry mainstream brands that are widely known, while smaller vacuum cleaner stores are more likely to carry lesser-known specialty brands. When evaluating vacuum cleaners from different brands, it's important to consider things like the unit's air flow, and the warranty protection offered.
