Dyson's V9 Motorbar Is the Lightest Stick Vacuum They Make, and Amazon Keeps Cutting the Price

What it is

The Dyson V9 Motorbar is Dyson's lightest cordless stick vacuum, positioned below the V15 Detect and V12 in the 2025 lineup. It has a Hyperdymium motor spinning at up to 120,000 RPM, up to 100 Air Watts of suction, a seven-cell lithium battery rated for up to 40 minutes of fade-free runtime in Eco mode, and a Motorbar cleaner head with anti-tangle comb technology. It converts to a handheld for stairs, cars, and furniture.

MSRP is $589.99 on Dyson. Real-world pricing has been dramatically lower: Amazon has listed it at $349.99, and Kotaku tracked it at $270 during a clearance.

What's interesting

Weight is the single most important spec on a stick vacuum, and the V9 Motorbar is 33% lighter than the V15. VacuumWars measured 4.9 lb at the wand, which is light enough for a one-handed overhead clean of a ceiling fan or door frame without the stick version's pivot fatigue. For anyone who has gripped a 7 lb Dyson through a full house clean, the difference is immediate.

The Motorbar cleaner head is the anti-tangle mechanism Dyson originally debuted on the V12. It has hardened-plastic combs embedded in the brushroll that strip long hair as it rolls, so the brush never becomes a hair snake that needs manual cutting. TechRadar confirmed the head works as advertised on shedding-dog households, which is the worst-case scenario.

Battery life is up to 40 minutes in Eco mode, roughly 20 minutes in Auto, and about 8 minutes in Boost. The battery is user-removable and replaceable via Dyson's direct-parts store. Whole-machine HEPA filtration is included at this price tier, which is not a given at competitors below $400.

What's missing or unverified

There is no laser light in the floor head. The V15 Detect's laser illumination of dust and the piezo particle counter are the Dyson features that most tangibly differentiate upmarket models. The V9 Motorbar skips both.

No LCD screen. The V9 shows battery level and mode via basic LEDs, while V15 and V12 have a small dot-matrix display with runtime countdown and particle counts. For buyers who want the real-time data feedback, the V9 is a step down.

The docking station is basic. There is a wall mount with a charger, but no automatic empty base (the Dyson Gen5Outsize offers one). The bin is 0.2 gallons, which is small enough that single-floor apartments will empty every clean.

Amazon pricing volatility is the asterisk. Dyson list is $589.99 and the Amazon price moves between $349.99 and $589.99 inside a single quarter. Buyers should not pay MSRP if they can wait a cycle.

Who it's for

Apartment and small-house owners with a single floor of hard floor and occasional rugs. Pet owners who want the anti-tangle head. Anyone for whom a 4.9 lb vacuum matters ergonomically. Buyers chasing the lowest Amazon price on a new-generation Dyson.

Not for: buyers who want laser dust detection or particle telemetry (V15 Detect is the answer), households with extensive high-pile carpet (where a plug-in upright is still more effective), or anyone who needs an auto-empty base.

Accessories and what's in the box

The V9 Motorbar ships with the main stick, the Motorbar head, a combination tool that converts between crevice and dust brush, a mini motorized tool for upholstery, the wall-mount dock, and a 4A charger. The mini motorized tool is the detail that matters for pet owners: it is a tiny brushroll version of the Motorbar and handles car seats and stairs without tangling. The combination tool is the weakest of the group; a small dust brush on a stick works but does not rotate.

The battery pack is a single seven-cell unit that slots in at the grip. Dyson sells replacement packs for roughly $120, and the V9 battery is compatible across the V9 range, which is useful for long-term ownership.

Verdict

The V9 Motorbar is the Dyson for people who want Dyson's fundamental strengths (powerful motor, anti-tangle head, HEPA filtration, replaceable battery) without paying for the detect-laser theater of the V15. At $349.99 it is the best-value stick vacuum Dyson sells; at MSRP it is overpriced against the Shark Stratos Cordless and Tineco Pure One S15. Wait for a sale, then buy.
