Power
Each cordless vacuum cleaner is powered by a 22.2v rechargeable battery. This is a fade-free battery; meaning that you will get consistent power from the vacuum up until the battery is completely drained instead of having the power fade over time.
The battery life will vary between each cordless vacuum as you will learn in a moment, but I want to point out that the battery is affected by the "Dual Power Mode" feature built into each of the vacuums. One setting allows for more battery life at the expense of suction power, while the other setting allows for a more powerful suction at the expense of battery life.
Technology
The technology behind the superior suction of these vacuums is arguably one of the best-selling points as well. Each has what's called a Dyson digital motor. This motor spins up to 104,000 times a minute and powers the suction that has made Dyson vacuums such great products.
This suction is in part due to what Dyson calls Root Cyclone™ technology. This technology uses powerful centrifugal forces to pull dust and dirt from the air. One of the great advantages of this is the fact that a Dyson vacuum does not require any vacuum bag. Vacuum bags are one of the main contributors to a vacuum losing suction over time.
Capability
This is where the Dyson cordless vacuum cleaners begin to differentiate themselves a bit. And depending on your specific needs, you may find one more suitable than the other.
- The Dyson DC34: This is a vacuum great for small jobs. It's a handheld and one of the lightest you will find on the market with this kind of suction power. It weighs 2.9 lbs and includes a combination and crevice tool for hard to reach places. You will get about 15 minutes of battery life with this vacuum but it will be reduced to about 6 minutes in its max mode, but you'll get way more power out of it. This is the kind of vacuum you want around the house for small spills or to vacuum your car or boat.
