Dyson V8 versus Shark Rocket Pro: Cordless or Corded Stick?
The Dyson V8 is a cordless stick (2.53 kg) with up to 40 minutes of run time; the Shark Rocket Pro (HV371) is a corded stick with a 25 ft cord, a larger 0.64 L dust cup and a 5-year warranty against Dyson's 2 years. The choice mostly comes down to cordless convenience versus unlimited run time.

Shark backs the Rocket Pro with a 5-year limited warranty, against 2 years for the Dyson V8, and gives it the larger dust cup (0.64 L against 0.53 L). The Dyson V8 cordless answers with a cordless design and a lower listed weight, 5.58 lb (2.53 kg) against 8.58 lb (3.89 kg) for the shark rocket pro stick vacuum. They are both stick vacuums but solve different problems: the V8 runs on a battery and goes anywhere, while the Rocket Pro plugs in and never runs down. This page compares published specs only; we have not tested either machine.
Dyson V8 versus Shark Rocket Pro: what separates them
Pick the Dyson V8 if you want to grab a vacuum and clean without finding an outlet, especially in a smaller home, an apartment or a car. Pick the Shark Rocket Pro if you have a larger area to cover in one go, want no battery to worry about, or prefer a bigger dust cup and longer coverage. Neither is objectively better.
A note on naming: the Shark covered here is the Rocket Pro DLX Corded Stick Vacuum, model HV371. It is not a cordless Shark.
Specs side by side
| Spec | Dyson V8 | Shark Rocket Pro (HV371) |
|---|---|---|
| Type | Cordless stick | Corded stick |
| Power | Rechargeable Li-ion battery | Plugs into 120 V outlet, 500 W |
| Run time | Up to 40 minutes | Limited by cord reach, not battery |
| Charge time | About 5 hours | Not applicable |
| Cord length | None | 25 ft (7.62 m) |
| Suction rating | 115 Air Watts (maximum) | Not published by Shark |
| Dust bin | 0.14 gal (0.53 L) | About 0.7 qt (0.64 L) |
| Weight | 5.58 lb (2.53 kg) | 3.89 kg (about 8.6 lb in retailer listings; see below) |
| Cleaning path | Not confirmed | 8.5 in |
| Filter | Fully sealed whole-machine filtration listed | Washable foam filters |
| Warranty | 2-year limited | 5-year limited |
Two cautions. Air Watts is Dyson's own suction measure and Shark does not publish a comparable number, so you cannot rank the two on suction from specs alone. Dyson's 40 minutes is a maximum; run time drops with higher power settings and motorized heads. On weight, Shark's own page shows a figure that appears to be a shipping weight and also says the vacuum weighs under 10 lb, so the 3.89 kg figure rests on retailer listings.
What cordless versus corded changes in daily use
Run time and coverage. With the V8 you plan around the battery: up to 40 minutes, then roughly a five-hour recharge. With the Rocket Pro, cleaning time is unlimited, but you are tied to a 25 ft cord, so larger homes mean moving to another outlet.
Dust capacity. The Shark's cup is somewhat larger, about 0.64 L against 0.53 L, so you may empty it less often on big jobs or in homes with a lot of pet hair. The difference is modest.
Handling. Shark lists Advanced Swivel Steering, LED headlights, and a handheld mode. The Dyson's lower listed weight, 5.58 lb (2.53 kg), suits stairs and furniture.
Warranty. Shark's 5-year limited coverage is the clearer advantage on paper, though limited warranties carry conditions and vary by seller and region.
Tools. Shark lists a crevice tool and an upholstery tool in the box. We could not confirm Dyson's tool list on its own page, so check the product page before relying on it.
Which home suits which stick
- Apartments and small homes: the V8's cordless design suits quick, frequent cleanups, and you avoid dragging a cord around furniture.
- Larger single-floor spaces: the Rocket Pro avoids stopping mid-job for a recharge, provided outlets are reasonably placed.
- Pets: both are bagless and suit pet owners on paper. The Shark's larger cup holds more between empties; the V8 is easier to carry to stairs and furniture.
- Carpet and hard floors: both are listed for carpet and hard floors. Specs cannot tell you which cleans deeper, so look at independent testing if that is your priority.
- Filtration: Shark's page lists washable foam filters and no HEPA filter for this model, and the Dyson V8 is not described as HEPA in the information we used, so do not assume HEPA on either unit.
For wider lineups, see any Dyson models or Shark vacuums page; Dyson stick models models give more cordless options, and you can compare other vacuums the same way across other models.
The corded vs cordless vacuum guide covers the trade-off for other models, and the V8 Absolute vs Rocket Pro page sets the Absolute version of the V8 against the same Shark.
Caveats behind the numbers
- Battery aging. A cordless vacuum's run time can shrink as the battery ages; a corded one does not have this issue. Replacement battery details are not covered here.
- Run time is a best case. Dyson's 40 minutes is a maximum, not a typical figure on carpet.
- Availability and price change. Check current price and stock on each product page.
- Specs are from listings, not testing. A few figures came from manufacturer listings or retailer conversions only.
How long does the Dyson V8 take to charge?
The Dyson V8 takes about 5 hours (300 minutes) to charge fully, according to Dyson's listing. It then runs for up to 40 minutes. The 40-minute figure is a maximum, so running time on carpet or in higher power modes will be shorter. By contrast, the corded Shark Rocket Pro (HV371) has no battery and no charging step. Instead it uses a 25 ft (7.62 m) cord, so you would move between outlets in larger homes. If you often need a quick top-up between sessions, a five-hour recharge is worth planning around.
How long is the Shark Rocket Pro cord?
The Shark Rocket Pro HV371 has a 25 ft (about 7.62 m) power cord, as listed on Shark's product page. That reach is measured from the outlet to the vacuum, so your actual cleaning radius is the cord length minus the route it takes around furniture and doorways. It is usually enough for a room or two before you need another outlet. The Dyson V8 has no cord and offers up to 40 minutes on a battery, while weighing 2.53 kg against the Shark's 3.89 kg.
