The catch
Dyson V9 Motorbar
A lower suction rating and a focus on the smaller machine make it less attractive as a floor-first upgrade.
Side by side
This V9 Motorbar package is the better pick if the stairs, the car and a furry sofa matter as much as the floor does. Its Amazon kit comes with the Hair screw tool. The V8 Cyclone fits better when you mainly want longer floor cleaning, button operation and the higher stated suction. Both have swappable batteries, so the battery will not decide between them.
Before you buy
Motor-driven agitation across fabric is something the Cyclone’s crevice tool cannot replicate, and the V9’s included powered small brush does it. In a home where cleaning goes from the floor to the stairs and sofa, that attachment can be worth more than paying for the higher floor-machine rating.
Where this comes from
Dyson V9 Motorbar: V9 package includes Hair screw tool and lists 4.6 pounds. Dyson V8 Cyclone: Cyclone package includes Motorbar and crevice tool.
The catch

The catch
Despite the higher suction rating on this vacuum, the sofa may still need something else bought.

Dyson V9 Motorbar: V9 package includes Hair screw tool and lists 4.6 pounds. Dyson V8 Cyclone: Cyclone package includes Motorbar and crevice tool.
Both let you swap batteries quickly. If you clean several rooms, you can weigh the cost of the V9 plus a compatible spare against the Cyclone package instead of assuming 60 versus 40 minutes guarantees a real floor session that is 50% longer.
Dyson V9 Motorbar: Click-in battery and up-to-40-minute claim. Dyson V8 Cyclone: Click-in battery and up-to-60-minute claim.
On floors, the Cyclone’s button and Medium mode make everyday use easier. For a pet seat, the V9’s included Hair screw tool changes what you find in the box. Neither comes with a separate illuminated soft roller, so do not pick either one hoping for the V15’s two-head floor kit.
Dyson V9 Motorbar: Motorbar plus Hair screw and crevice tools. Dyson V8 Cyclone: Motorbar, crevice tool and three manual modes.

Spec by spec
| Spec | Dyson V9 Motorbar | Dyson V8 Cyclone | In practice |
|---|---|---|---|
| Small powered tool | Hair screw tool in this Amazon package | Not in this Motorbar package | If your home has fabric furniture, compare what the whole kit costs. |
| Maximum suction claim | 100 AW | 150 AW | A 50% gap in AW does not mean a 50% improvement on a rug. |
| Published maximum runtime | 40 minutes | 60 minutes | They are maximum figures. They do not come from matched powered-head tests. |
| Spare battery option | Click-in battery | Click-in battery | A charged spare bought on its own works in either. |
| Display | LCD with remaining runtime | Three selectable power modes | With the V9 you can plan around the charge you have left, and you do not have to buy for the higher AW figure. |
