Both are excellent; V12 is lighter, V15 is stronger and larger.

If you’re torn between two great cordless vacuums, I get it. The dyson v12 vs v15 choice comes down to how you clean day to day. I’ve used both around pets, stairs, and a mix of hard floors and rugs. Both are excellent, but one offers lighter handling while the other brings raw power and a bigger bin. I’ll walk you through what stood out in my tests so you can pick the right fit for your home.

Is Dyson V12 Detect Slim Good?

Yes, for most homes and daily cleaning, the Dyson V12 Detect Slim is a smart pick. It’s light, nimble, and easy to use for quick runs. It still cleans deep, yet it never feels like a chore to grab. If you want a vacuum that you can use with one hand without fatigue, the V12 is hard to beat. It is great for smaller spaces, condos, stairs, and hard floors.

In my testing, the V12 became my “grab-and-go” tool. I loved the power button over a trigger. My wrist thanked me after a week of nightly crumb cleanups. The laser head made dust on my oak floors very visible. I even used it after dinner under the table and found fine flour I had missed. It’s become my daily driver, while the bigger vac waits for big weekend cleans.

What Makes It Stand Out / Key Features

• Lightweight build around 5.2 lb for easy one-hand use
• Laser Slim Fluffy head reveals dust on hard floors
• Piezo sensor and LCD show real-time particle counts
• Up to 60 minutes of fade-free runtime (non-motorized tools)
• Whole-machine filtration captures fine particles and allergens

What I Like

• Power button (no trigger) reduces hand strain on longer runs
• Very easy to steer, especially around chair legs and tight nooks
• Laser makes invisible dust obvious, so floors actually look cleaner
• Strong suction for its size; handled pet hair on rugs better than expected
• Quiet enough on low to clean late without waking anyone

What Could Be Better

• Smaller bin (about 0.35 L) means more frequent emptying
• Not as strong as the V15 on thick carpets
• Battery life drops fast on Boost mode

My Recommendation

If you want a light, daily-use vacuum that still cleans deep, get the V12. It’s a great value when weight and comfort matter most.

Best For	Why
Small to medium homes	Lightweight, easy to store, strong everyday cleaning
Hard floors and stairs	Laser head shows dust; nimble body handles steps well
Users with hand or wrist fatigue	Power button design and low weight reduce strain

Is Dyson V15 Detect Good?

It depends on your home. If you have lots of carpet, kids, and pets, the Dyson V15 Detect is a powerhouse. It has stronger suction (up to about 230 air watts), a larger bin, and better deep-cleaning on thick rugs. It’s heavier than the V12, but it cleans like a corded vacuum in a cordless body.

In my home, I reach for the V15 when the week gets messy. It pulls grit from entry rugs and lifts hair from a wool runner my dog loves. The LCD readout is oddly satisfying as it shows particle counts rise and fall. The trigger takes a bit of getting used to, but the payoff is serious cleaning in fewer passes.

What Makes It Stand Out / Key Features

• High suction power (up to ~230 AW) for deep carpet cleaning
• Laser Slim Fluffy head plus a motorized head for rugs
• Piezo sensor with LCD that visualizes particles by size
• Up to 60 minutes of run time in Eco with non-motorized tools
• Larger bin (about 0.76 L) reduces emptying during big cleans

What I Like

• Best-in-class pickup on thick carpet and area rugs
• Big bin saves time during whole-home weekends
• Hair screw tool is great for pet beds and upholstery
• Adaptive power boosts suction as dust levels rise
• Sturdy feel with premium build and seals

What Could Be Better

• Heavier than the V12; wrist fatigue can creep in
• Trigger switch is less comfy for long cleaning sessions
• Higher price, especially with extra tool bundles

My Recommendation

Pick the V15 if your home has lots of carpet, pets, or heavy weekly mess. It’s the cleaner for deep jobs.

Best For	Why
Large homes and families	More power and bigger bin for long sessions
Carpet-heavy spaces	Strong suction extracts grit and pet hair
Pet owners	Hair screw tool and deep-clean heads excel with fur
