Things you may want to know about before making a purchase, because many other people concern about them.
First, all of the Dyson cordless vacuum cleaners are bagless and battery powered. All of them do NOT operate while charging, which means you cannot use it to vacuum with cord attached.
Second, all of the Dyson cordless units use Trigger type On/Off design, Dyson claimed that such design can save battery power and then extend running time. However, with this design, you have to keep pressing the trigger when in use. Some people like such design while others does not like it because they feel it cause finger fatigue. So you’d better try it before buying if you never had one. Test it at local stores, or borrow one from friends or neighbors if possible.
Third, though the battery pack on the unit is replaceable, you have to use a screw driver to unscrew 2 (on V6) or 3 (on V7,V8,V10) phillips screws to remove the battery pack. So this is not a design that allows you to have a second battery pack to conveniently swap to use in your daily cleaning jobs. For those who prefer a cordless vacuum with 2 swappable batteries, please think over.
Now, if you decide to buy one but get confused by the various similar models, here are some info that may make it clear. We list major difference between them.

About V6. Though it is the lowest price one of the four. But its running time on low setting is the shortest one, bin is the smallest, tools are harder to switch.
V7 use the direct drive cleaner head, has better brush bar power than the V6 and longer running time on low setting, but suction power on low setting is down from 28 air watts to 21 air watts compared to V6.
V8 has greater suction power than the V7, 28 air watts versus 21 air watts on previous model at low setting, 115 air watts versus 100 air watts at high setting. And it provides 10 minutes longer running time on low setting. But the change on the battery also increase its charging time, the other models only require 3.5 hours to recharge while the V8 needs 5 hours to fully charge.
V10 provides the most powerful suction on the max mode, much greater than the previous models. Its design is different from the previous models, such as the hygienic point and shoot empty mechanism, adding one more power mode, the one piece filter to replace the pre-motor filter and post motor filter. It can run up to 60 minutes with a non motorized tool on low setting(16 air watts is not strong enough for most vacuuming jobs), but the running time on medium (33 air watts suction power) and high setting(151 air watts) are not better than the V8 low setting(28 air watts) and high setting(115 air watts). One more thing you should know about the Cyclone V10 — with the redesign on the unit, you have to remove the tools/wand before emptying the bin. The previous models do not require you to remove tools/wand to empty. It seems the new design is not as convenient as the older models, but for the old models, there is also chances to open the dust bin accidentally, then spill dust.
Buy the V6 if you just want to try a Dyson cordless vacuum.
V7 or V8. The V7 is a little cheaper than the V8. Buy the V7 if you want 1.5 hours shorter charging time. Choose the V8 if you want better suction power and longer running time.
Buy the V10 if you have enough budget, and need one with larger bin, and the most powerful suction for occasional intensive cleaning.
Dyson Cyclone V10 Absolute vs Animal vs Motorhead Cordless Vacuum Cleaners
The Cyclone V10 has some redesign compared to previous models, such as adding one more power mode, hygienic “point and shoot” empty mechanism, one piece filter to replace dual filters. It provides much more suction power at max mode than the V6,V7 and V8 models.
The V10 Absolute and Animal is the same except for color and accessories. The Motorhead is different from the above versions, it has a small dust cup and it does NOT come with the new Torque drive cleaner head, instead, it includes the Direct drive cleaner head like the previous generation.
| Vacuum Cleaner | Bin Capacity | Weight | Color | Included Tools |
| V10 Absolute | 0.2 gallons | 5.9 lbs | Blue,Copper,Black | Torque drive cleaner head,Soft roller cleaner head,Mini Motorhead,Mini soft dusting brush,Combination tool,Crevice tool,Docking station,Charger |

Dyson V7 Absolute vs Motorhead vs Animal vs HEPA Cordless Vacuum Cleaners
Not all of the V7 cordless models feature HEPA filtration; the color of the cyclone part and the wand is the obvious thing that makes them different from each other; the model that comes with more tools are more expensive.
