The standard Shark vs Dyson vacuum review compares and contrasts features of two or more vacuums and gives an overall rank of the best one among them. Well, that would be immensely useful if everyone used their vacuums in exactly the same way. However, people use it in varying ways and for multiple purposes, which means that what might work for one person might not work for someone else.
Here are just two contrasting ways homeowners use their vacuums:
1. Light Use
Suction power isn’t particularly important to you if you need a vacuum only for light use, especially if you don’t have any carpets on your floor or just have a few small carpets that you don’t intend to clean with your vacuum.
In this case, you might be interested in saving a bit of cash simply by going for the most affordable product that can get the job done. For instance, you might take the roughly 140AW (AW or Air Watts is an indicator of suction power) to 160AW Shark Rotator – NR96 – Powered Lift-Away, which is approximately less than half the price of the 170AW Dyson DC47 Multi Floor.
2. Heavy Use
Alternatively, you might be the type of person who loves cleaning and might even do it every other day, or you simply have no choice because the mess that piles up in your house within a week could make it look like the aftermath of a war zone.
In your case, you need to consider three critical aspects:
i. Powerful Suction
Powerful suction is pretty much self-explanatory. You would rather go for the 270AW Shark Rotator NV752 Powered Lift-Away (TruePet), rather than the 180AW Dyson Cinetic Big Ball (Animal). What’s more, you would be paying almost half of the Dyson’s price.
ii. Sustained Suction Power
However, your preference would shift back to the Dyson’s Cinetic Ball, if you consider sustained suction power in long-term use. This is because such a vacuum has no filter at all, making it capable of long-term extensive use without loss of suction, as there’s no filter to clog up with dust and restrict air flow. For such a long term benefit, that would certainly be well worth the price.
As you can see, despite Shark’s NV752 having a higher AW, the Dyson Cinetic Big Ball is more likely to efficiently sustain suction power since it doesn’t have any filter. In other words, although Air Watts is an indicator of a vacuum’s suction power, there are several other factors that can affect this suction power, especially with extended use.
Such factors include:
- Increased resistance as the bag or dust cup fills with dirt
- Turbulence in the vacuum hose and wands
- Filter loading
- Airflow restrictions between cleaning tools and floor or other surfaces
iii. Energy Efficiency
After all that extended use, you don’t want to end up with a significantly increased electricity bill at the end of the year. This raises the need for an energy efficient product.
On this aspect, you would need to consider the features that use energy, apart from efficiency of the core components. Having more features might mean it uses more energy to run such features, which might be taking energy from the core functions, or sapping too much energy unnecessarily.
As you can see, the way you use your vacuum will influence your product choice. Shark and Dyson vacuum reviews often only tell you what’s best overall, not what’s best for you.
