If you've used a variety of vacuum cleaners over the years, you'll have noticed that some are more powerful than others. Some models don't offer much suction power, which makes it more difficult and more time-consuming to vacuum up dust and debris. Others, in contrast, provide so much suction that they seem to pick up everything effortlessly.
So how do you know which one to buy? Well, most of the best vacuum cleaner manufacturers will tell you the power of the motor in Watts. However, this doesn't necessarily tell you how much suction you'll get from it, because it's as much about how efficiently the vacuum is designed as how powerful it is. Or to put it another way, if a high-wattage vacuum is poorly designed, it still won't provide much suction.
