Main trade-off
Dyson V15 Detect
The lighter listed stick still needs a held trigger. Its small furniture attachment must be checked on the exact selected listing.
Head-to-head
Choose V15 Detect for dry fur and a lighter complete stick if holding its trigger suits you. Choose V16 Piston Animal Submarine if button control, its confirmed Hair screw tool 2.0 or hard-floor washing matters more than the extra weight and wet-head care. Neither extracts urine from carpet. Try the grip and emptying motion before treating either as an accessibility solution.
Before you choose
For dry fur upstairs, V15’s listed complete-stick weight is about 0.7 lb lower. That is useful if carrying the whole cleaner is the problem. If the difficult part is keeping a finger on the trigger through a sofa-cleaning session, V16’s button addresses a different requirement. The heavier model can therefore remain the more workable candidate for one person while being the wrong choice for another. Check the actual grip, attachment and bin-emptying action. We have no force or fatigue test that can decide that for you.
What this is based on
About 7.5 minus 6.8 equals 0.7 lb for the listed complete sticks. Trigger versus power button is documented independently. These facts do not establish handheld weights or a medical benefit.
Main trade-off
The lighter listed stick still needs a held trigger. Its small furniture attachment must be checked on the exact selected listing.
Main trade-off
The heavier stick and wet head bring separate handling demands. After washing, the head needs level transport, emptying, cleaning and roller drying.


Compare Dyson V15 Detect and V16 Piston Animal Submarine for fur, stairs, trigger handling and wet-head storage. See where the newer package adds work.
Both serve a premium mixed-floor household with pets. The real choice combines how you hold the vacuum, where the hair lands and whether hard-floor washing earns its extra care and storage.
Winner by situation
V15’s complete stick is listed about 0.7 lb lighter. The claim does not cover every handheld setup.
V16 uses button power. A personal handling check still needs to include emptying and attachments.
V15 avoids the wet-head routine, but it cannot replace a hard-floor washer.
This V16 Submarine box documents both. Allow for care and older-tool incompatibility.
Neither is a carpet or upholstery liquid extractor. Keep liquids out of dry vacuum heads.
The evidence does not establish a matched noise or pet-response winner.

With a puppy and a small apartment, it is tempting to buy one machine for every mess. V16’s washing head still has to come off into its drip tray, travel level to the sink and be cleaned before the roller air-dries. A cupboard that stores the dry stick is not automatically suitable for that wet routine. V15 avoids this added chore for dry hair, but supplies no washing function. Neither extracts urine from carpet or a fabric pet bed, and the reviewed instructions do not establish raw-feces handling or sanitization.
V16 manual pages 15 and 16 define hard-floor washing and the immediate tray, sink and drying sequence. V15 is dry-only. The consequence concerns space and steps, with no claim about cleaning time or hygiene outcomes.
If an older Dyson’s small tools are shared between the stairs, car and pet bed, do not count that drawer of accessories as a free V16 starter kit. Dyson explicitly excludes sharing its intelligent attachments with other current models. V16 Submarine does include Hair screw tool 2.0, so compare what that exact box covers before buying more. V15 still needs an exact package check. The current manufacturer URL now opens a different car-cleaning bundle, which cannot settle the Amazon box contents.
V16 US compatibility FAQ and box contents are explicit. The V15 redirect and retailer-dependent accessory warning are retained as uncertainty rather than proof that its furniture tool is missing.
Neither the Animal name nor 315 versus 240 air watts tells you which cleaner will disturb a sleeping pet less. We have no matched sound or animal-response test here. Keep that uncertainty if noise is the reason you are replacing a vacuum. For fur on furniture, verify the small powered tool and the fabric instructions instead of choosing from the floor-suction headline.
The published quantities measure suction, not sound. No comparative acoustic or animal-response evidence was found in the exact records reviewed.

Holding a trigger is the obstacle, and V16’s button and heavier body suit your own handling check.
Meaningful differences
| What changes | Dyson V15 Detect | Dyson V16 Piston Animal Submarine | Why it matters |
|---|---|---|---|
| Holding the cleaner | V15 uses a trigger to run. Its listed complete-stick weight is about 6.8 lb. The weight of a particular handheld and tool combination is not established here. | V16 starts with the red power button above its display. The listed complete-stick weight is about 7.5 lb. No operating-force or wrist-load measurement is supplied. | The lower carried weight and the simpler power action favor different needs. Neither establishes less fatigue. |
| Furniture and existing accessories | V15 retailer packages can differ. The reviewed current product URL redirects to an Absolute car-cleaning bundle, which is not proof of the tools supplied with Amazon model 626417-01. | The US Submarine package lists Hair screw tool 2.0. Dyson says V16 intelligent tools and attachments cannot be shared with other current Dyson vacuum models. | A V16 purchase can mean replacing useful older tools as well as the main vacuum. Confirm the complete setup. |
| Wet cleanup and storage | This V15 Detect package is dry-only. Its filter must dry completely for at least 24 hours after washing. The small furniture tool depends on the selected retail package. | The Submarine 2.0 head washes hard floors. After use it goes immediately into the drip tray, is carried level to a sink, emptied and cleaned, with the roller air-dried separately. It is not a carpet liquid extractor. | A small apartment needs room for the care sequence, not just somewhere to stand the vacuum. |
| Peak suction | 240 air watts. | 315 air watts. | Peak suction does not establish better embedded-hair pickup or a quieter machine. |
| Maximum runtime | Up to 60 minutes, with runtime dependent on mode and attachment. | Up to 70 minutes, with runtime dependent on mode and attachment. | These are manufacturer maximum claims, not matched powered-head tests. |
What you give up
Recommendation switch
Choose Dyson V15 Detect. V15 has the lower listed complete-stick weight, if its trigger suits you.
Choose Dyson V16 Piston Animal Submarine. V16 changes the power action. It does not establish a lower physical load overall.
Choose neither. That requires a suitable extraction method and the fabric care instructions.
What matters in practice
You want less effort collecting fur, but the lighter stick requires a trigger and the wet-cleaning upgrade creates a separate sink and drying routine.
