The catch
Dyson V8
A powered sofa attachment is not in the box with the basic offer.
Side by side
Dyson V8 vs Dyson V9 Motorbar: A sofa tool is what V9 adds, not a higher suction rating
Quick verdict
V9 Motorbar makes sense if the jobs you do can use its lighter listed weight, click-in battery and included Hair screw tool. V8 makes sense if the basic Motorbar-and-crevice kit is enough and its current offer is better. With a 100 AW rating against the V8’s 115 AW, the V9 should not be read as a suction upgrade just because it is newer.
Before you buy
Why, and what it costs you
The upgrade that matters is in carrying and coverage
In this exact offer the V9 drops about 18% of the listed complete weight and adds a powered furniture brush. For upstairs rooms and a furry couch, those can be worthwhile improvements even with a lower AW rating. Neither percentage is a predictor of carpet pickup.
Where this comes from
Dyson V8: 5.58 pounds, 115 AW, Motorbar and crevice kit. Dyson V9 Motorbar: 4.6 pounds, 100 AW, Hair screw tool in exact package.
The catch
Dyson V9 Motorbar
Despite the newer platform, its stated maximum AW figure is lower than this V8’s.

Dyson V8: 5.58 pounds, 115 AW, Motorbar and crevice kit. Dyson V9 Motorbar: 4.6 pounds, 100 AW, Hair screw tool in exact package.
For a round that gets cut off, a spare battery matters more than an equal maximum claim
Their records show a 40-minute maximum for both. The V9 can take a charged click-in spare, whereas replacing the V8 pack is a service task. If you do run out mid-clean, weigh that ownership difference and do not treat the shared maximum as a tie.
How we worked this out
Dyson V8: 40-minute maximum and service-replaced battery. Dyson V9 Motorbar: 40-minute maximum and click-in battery.
Count the sofa job in the price of the bundle
The small powered brush that ships with the V9 is missing from the current V8 offer. If you cannot do without that attachment, compare the total cost of a compatible tool plus the vacuum before concluding that the cheaper listing is better value. Finding an attachment name elsewhere in the product family does not prove it is in this box.
