Dyson V8 Cordless Vacuum Review: Key Features & Benefits
The Dyson V8 cordless vacuum is a lightweight, bagless stick vacuum designed for convenient everyday cleaning on floors and above-floor areas. It offers cordless flexibility, making it easy to move around the home for quick and versatile cleaning.
It is powered by a digital V8 motor spinning up to 110,000 RPM, delivering around 115 AW of suction power for effective pickup of dust, debris, and pet hair on different surfaces. The Motorbar cleaner head helps deep clean floors while reducing hair tangles by automatically removing wrapped hair from the brush bar.
Weighing about 5.58 lbs, it is easy to carry and maneuver, and it quickly converts into a handheld vacuum for cleaning stairs, furniture, and tight spaces. It also uses a fully sealed 5-stage filtration system that captures 99.99% of particles as small as 0.3 microns, helping improve indoor air quality.
Strong Motor Performance
The Dyson V8 is powered by a digital V8 motor that spins up to 110,000 RPM, generating about 115 AW of suction. This gives it enough power to handle everyday dirt, dust, and pet hair on both carpets and hard floors. It’s designed to maintain consistent performance for routine home cleaning tasks without needing a corded vacuum.
Motorbar Cleaner Head
The Motorbar cleaner head is built to deep clean multiple floor types while actively preventing hair wrap. It uses polycarbonate vanes to automatically remove long hair and pet hair from the brush bar as you vacuum. This helps reduce manual cleaning and keeps performance consistent, especially in pet-friendly homes.
Up to 40 minutes Runtime
In standard mode, the vacuum delivers up to 40 minutes of fade-free suction on a full charge. This is enough for most small to medium home cleaning sessions. In Max mode, it provides stronger suction for up to 5 minutes, which is ideal for stubborn dirt or concentrated messes.
Two Power Modes
The Dyson V8 includes two cleaning modes to balance performance and battery life. Standard mode is optimized for general cleaning and longer runtime, while Max mode increases suction for deep cleaning tasks. This flexibility allows users to adjust power depending on the level of dirt.
Lightweight Design
Weighing only around 5.58 lbs, the Dyson V8 is easy to carry and maneuver across different areas of the home. Its lightweight build makes it especially useful for cleaning stairs or moving between rooms quickly. It reduces fatigue during longer cleaning sessions.
Converts to Handheld
The vacuum quickly transforms into a handheld unit for more targeted cleaning. This makes it convenient for cleaning cars, furniture, upholstery, and tight corners. The conversion is simple, allowing you to switch tasks without hassle.
3 included attachments + Wall Dock
It comes with multiple tools designed for different cleaning needs, from high surfaces to low and narrow spaces. These attachments help improve versatility so you can clean ceilings, corners, and furniture effectively. The wall dock also provides easy storage and charging, keeping everything organized.
Hair Screw Tool
The Hair Screw Tool is designed with an anti-tangle conical brush bar that removes long hair and pet hair quickly. It is especially useful for cleaning pet beds, car seats, and stairs where hair buildup is common. Its design helps prevent clogging and reduces maintenance time.
Advanced Whole-Machine Filtration
The Dyson V8 uses a fully sealed filtration system with a post-motor HEPA filtration, capturing 99.99% of particles as small as 0.3 microns. This includes fine dust, allergens, and microscopic debris that can affect indoor air quality. It ensures cleaner air is released back into your home while vacuuming, making it ideal for allergy-sensitive users.
Durable Build Quality
The Dyson V8 is made from strong yet lightweight materials designed for long-term use. It comes with a 2-year limited warranty and Dyson support for added peace of mind. The build quality ensures it can handle regular use without compromising performance.
Smart Setup Support
Users can register the device on the MyDyson app to access guides, maintenance tips, and support. This helps extend the lifespan of the vacuum by ensuring proper care and usage. It also provides helpful troubleshooting assistance when needed.
Charging Note
The product is shipped partially charged, so a full charge is recommended before first use. This ensures optimal battery performance right from the start. Proper initial charging also helps calibrate the battery for long-term use.
How We Tested
We tested the Dyson V8 cordless vacuum through a series of real-world home cleaning scenarios to evaluate its performance across noise level, suction power, different floor types, and battery life.
Noise Test – We measured the vacuum’s sound output during Standard and Max modes to assess everyday usability and peak performance noise.
Suction Test – We tested suction strength by evaluating how effectively it picked up fine dust, crumbs, and pet hair in a single pass.
Carpet Test: Rice, Cereal & Pet Hair – We scattered rice, cereal, and pet hair on carpet to check deep-cleaning ability and debris pickup efficiency.
Hardwood Floor Test: Rice, Cereal & Pet Hair – We repeated the same debris test on hardwood floors to evaluate pickup performance and scattering control.
Battery Runtime – We ran the vacuum continuously in Standard and Max modes to measure actual runtime against manufacturer claims.
Performance Test
Noise Test
We tested how loud the Dyson V8 cordless vacuum gets during operation. A sound level meter was placed about 2 feet away while running the vacuum on Max mode to measure peak noise levels. The Dyson V8 recorded 76 decibels, showing a noticeable increase in sound when using higher power settings.
Suction Test
We tested the suction power of the Dyson V8 cordless vacuum using an airflow meter placed at the hose to measure air movement. The results showed an airflow of 442 ft/min and 31.03 CFM, indicating strong suction performance suitable for everyday cleaning tasks.
Suction Test (Sealed Setup)
We sealed the airflow holes to measure the vacuum’s maximum suction potential under optimized conditions. With this setup, the Dyson V8 increased to 595 ft/min and 41.75 CFM, showing a noticeable boost in airflow performance when air leakage is minimized.
Overall Results
Based on the test results, the Dyson V8 showed stronger suction performance overall. Even in the sealed setup, where maximum potential was measured, it remained ahead in airflow and suction power compared to baseline conditions. This indicates that the Dyson maintains a clear advantage in raw suction strength during testing.
Carpet: Rice, Cereal & Pet Hair
We tested the vacuum on carpet using real-world debris like rice, cereal, and pet hair.
Rice Test
With rice, the Dyson initially pushed some grains forward and left a few behind, requiring an additional pass to fully clean the area. Near the end of the test, a small amount of rice was also released back onto the floor from the vacuum, indicating some debris retention issues during use.
Cereal Test
Next, cereals. The Dyson struggled here. It was actually crushing the cereal and making more of a mess. Then the roller got jammed and the vacuum stopped working. I had to flip it over and flared out the stucked cereal before it would run again. After that, it finished the job but definitely not smoothly.
Hair Test
We tested the Dyson vacuum on hair to see how well it handles longer debris. The Dyson V8 picked up the hair in just one pass and did not show any noticeable tangling on the roller, indicating smooth and efficient hair removal during use.
Overall Result
Overall, the Dyson V8 performed well in the sand test, picking up a higher amount of material compared to expectations. However, it showed some difficulty with real-world debris like rice and cereal, where additional passes were sometimes needed. On the other hand, it performed very well with hair, picking it up efficiently with no tangling, earning a 5/5 rating for hair performance.
Sand Test (Carpet)
For the sand test, we spread 100 grams of sand evenly across the carpet to evaluate pickup performance. The Dyson V8 was weighed before the test and recorded at 1,534 grams. After one pass over one-quarter of the area, it had already picked up most of the sand. When weighed again, the vacuum measured 1,628 grams, meaning it collected 94 grams of sand during the test.
Hardwood: Rice, Cereal & Pet Hair
We tested the Dyson V8 vacuum on rice, cereal, and pet hair on a hardwood floor to see if it can pick up all the debris effectively.
Rice Test
After the initial pickup, a clear issue became noticeable. The Dyson V8 seemed to perform well at first, but when it was put away, it left a few rice grains on the floor. More importantly, once lifted, it began dropping some of the collected rice back out of the unit. This suggests that the Dyson still has difficulty securely containing rice during and after use.
Cereal Test
Next, we tested cereal. The Dyson V8 started off okay, but it again left crumbs behind and even scattered cereal as it moved.
Hair Test
Next, we tested hair. The Dyson V8 performed perfectly, picking up all the hair in one pass with no brush tangles or need for repeated passes. Overall performance: 5/5.
Sand Test (Hardwood Floor)
Next, we tested the vacuum on hardwood floors using the same 100 grams of sand setup for consistency. The Dyson V8 was weighed before and after the test to measure how much debris it picked up. After cleaning, the vacuum weighed 1,632 grams, meaning it collected 98 grams of sand.
Battery Runtime
Next, we tested battery life on a full charge. The Dyson V8 vacuum was set to maximum power. It lasted 6 minutes and 7 seconds before it shut down.
Dyson V8 Cordless Vacuum Pros and Cons
✅ PROS
Strong Suction Power
The V8 delivers 115 air watts of suction power — and in testing, it mowed down faux fur, Cheerios, kitty litter, rice, and sand from both hard floors and high-pile carpets without skipping a beat.
Lightweight & Easy to Maneuver
Weighing only 5.75 lbs, it is incredibly easy to maneuver, whether you’re cleaning floors, ceilings, or tight spaces.
Decent Battery Life
You can easily switch between two power modes — Low and Max — to conserve battery and enjoy up to 40 minutes of runtime.
Anti-Tangle Technology
The Motorbar cleaner head utilizes Dyson’s latest hair detangling technology and features hair removal vanes to automatically clear hair as it cleans.
Converts to Handheld
For added convenience and versatility, you can convert the machine to a handheld vacuum to easily clean furniture, cars, and other hard-to-reach or high-up places, thanks to its lightweight, ergonomic design.
Great Attachment Bundle
It comes with a multi-purpose upholstery and brush tool, a crevice tool, and an anti-tangle screw — a really unique brush design that helps detangle and keep hairs from catching.
HEPA Filtration
The V8 features two filters — an interior HEPA filter and a pre-filter — that ensure it doesn’t clog and is ideal for capturing fine dust and allergens.
Easy Bin Emptying
To empty the dust bin, you just push the lever with the trash can icon — no-touch bin emptying included.
Affordable for a Dyson
While the V15 is more powerful, the V8 is half the price, lighter, and cleans average homes just as well — making it the best value premium vacuum in its class.
❌ CONS
No LED Headlights
The lack of LED lights is a big miss, especially at this price point — something you’d expect even on entry-level cordless vacuums these days.
Short Battery in Max Mode
In Max mode, battery life drops to around 7 minutes, which is something to consider for deep-cleaning sessions.
Battery Not Easily Swappable
The battery is technically removable, but not easily — you’ll need a screwdriver, which isn’t ideal. Swapping batteries should be quick and tool-free.
No Trigger Lock
There’s no trigger lock — you have to keep holding it down the whole time, with no way to lock it in place.
No Smart Features or Display
There’s no auto mode, no display, and no real-time feedback about dust levels or battery life — none of the smart features that are becoming more common.
Not Ideal for Large Homes
The V8 is best suited for someone with a smaller space, or someone prepared to tackle a larger home over a few separate cleaning sessions.
Not Free-Standing
It’s not free-standing, so you’ll need to securely prop it in a corner or mount it on its dock to keep it from falling.

The Dyson V8 clearly leads when it comes to suction precision — delivering consistent, measurable cleaning power across carpet, hard floors, and pet hair in every test we ran. But the Shark IZ340H punches well above its weight, offering a larger dust bin, a flexible wand that bends under furniture, and a 5-year warranty that more than doubles the Dyson’s coverage.
At the end of the day, it comes down to priorities. If raw suction performance and lightweight handling are non-negotiable, the Dyson V8 is worth every penny. But if you want a capable, versatile vacuum that gets the job done without the premium price tag, the Shark IZ340H is incredibly hard to beat. Curious how it holds up on its own? Read our full Shark IZ340H Review for the complete breakdown.

Frequently Asked Questions
How long does the Dyson V8 battery last?
Dyson advertises up to 40 minutes of runtime, but that’s in standard (Low) mode. In Max mode, battery life drops considerably — real-world users typically see around 6 to 7 minutes of Max mode before needing a recharge.
Can you leave the Dyson V8 on charge all the time?
Yes — the battery is designed to be left on charge to ensure your vacuum is ready for the next use. Dyson recommends charging the machine after every clean to maximize runtime.
How often should you clean the Dyson V8 filter?
Dyson recommends cleaning the filter at least once a month. Filter maintenance instructions can be found in the machine’s user guide. Always let it dry completely for at least 24 hours before reinstalling.
Why does my Dyson V8 keep cutting out?
If your Dyson V8 cuts out, pulses, or keeps shutting off, it could be because the machine is blocked — take it apart and check for blockages. The filters may also need cleaning, or the bin may need to be emptied.
Is the Dyson V8 good for pet hair?
Yes. The new Motorbar cleaner head features an active hair detangling system with plastic combs that remove hair as you vacuum. Testing with 7 and 14-inch hair found it mostly solved the age-old problem of hair getting tangled on vacuum brush rolls.
Can the Dyson V8 pick up water or liquids?
No — do not pick up water or other liquids with the Dyson V8. It is a dry vacuum only.
Final Verdict: Is the Dyson V8 Worth It?
After putting the Dyson V8 through real-world performance tests — from sand and pet hair to rice and cereal on both carpet and hardwood — the verdict is clear: this is a vacuum that shines brightest when it’s doing what it was built for.
The suction holds up in real-world testing, and hair performance was flawless — one pass, zero tangles, no roller jams. At just 5.58 lbs, it feels genuinely effortless to carry and maneuver from room to room.
That said, it’s not perfect. The cereal test was a struggle — the roller jammed, debris scattered, and it needed manual clearing before it could finish the job. Rice had similar issues, and if you’re counting on Max mode for deep cleaning, that 6-minute real-world runtime goes fast.
So who is the Dyson V8 actually built for? Pet owners, light-to-medium households, and anyone who wants a premium cordless vacuum without paying premium V15 prices. It handles hair, dust, sand, and everyday messes with ease — and the HEPA filtration means the air coming out is genuinely cleaner than what went in.
If you need a vacuum for large debris, very thick carpet, or whole-home deep cleans in a single session, you’ll want to step up to the Dyson Stick Vacuums V12 or V15. But for most people cleaning most messes most of the time, the Dyson V8 hits a sweet spot that’s hard to argue with.
