What is the Best Suction Power for a Vacuum Cleaner?

When you’re on the hunt for the perfect vacuum cleaner, the power of its suction is likely at the top of your list of considerations. Suction power is an important factor when it comes to vacuums, as it affects how well and how quickly your vacuum can clean. But with such a wide range of vacuums available, each claiming to have superior suction power, how do you know which model is right for you? Let’s break down what to look for when it comes to suction power in order to make sure you get the most out of your purchase. Learn What is the Best Suction Power for a Vacuum Cleaner?

Air Watts vs. Standard Watts

When shopping for a vacuum cleaner, two measurements will be mentioned frequently—air watts and standard watts. Air watts measure how much air is being sucked up by the vacuum cleaner a second whereas standard watts measure the amount of energy being used by the motor. In other words, air watts are more indicative of actual cleaning performance than standard watts. It’s not uncommon for manufacturers to list only their standard wattage ratings rather than their air watt ratings, so be sure to read reviews or contact customer service if necessary in order to determine real-world performance.

Suitable Suction Power Levels

The general consensus among experts is that 20-30 air watts per kg are ideal for lightweight vacuums while 40-50 air watts per kg are ideal for heavier models. This range should be enough power to pick up debris from carpets and hard floors alike without becoming clogged or overheating—two common issues with low-powered vacuums. Of course, there are exceptions; some models require higher levels of suction power due to their design and intended purpose—for instance, pet hair vacuums typically need around 50-60 air watts per kg in order to properly extract pet hair from carpets and upholstery.

Overall Efficiency

When looking at suction power figures alone isn’t enough; you also need to consider overall efficiency in order to ensure that you’re getting the best bang for your buck with your vacuum cleaner purchase. This means considering factors like filter quality (good filters will help retain suction power longer), noise levels (the quieter the better), battery life (important if you plan on using cordless models), and maneuverability (a good all-round model should be easy enough to move around furniture). All these elements can affect performance just as much as raw suction power, so make sure they aren’t overlooked when making your purchase decision!


Knowing what kind of suction power is best suited for your needs can help ensure that you find a vacuum that performs exactly as advertised without wasting any time or money on underperforming models. Generally speaking, 20-30 air watts per kg should suffice for lightweight models while 40-50 air watts per kg are suitable for heavier designs; however, certain types of vacuums may require more powerful motors depending on their intended use case. Be sure to consider overall efficiency when making your purchase decision too—look at factors such as filter quality, noise levels, battery life, and maneuverability in addition to raw suction power ratings! Ultimately these can all affect performance just as much as raw wattage ratings do!
