Reviews – Let’s Take a Closer Look

Dyson V16 Piston Animal

Pros

• Up to 315 AW suction — Dyson’s strongest yet
• CleanCompaktor™ compresses dust up to 40%
• Dual anti-tangle brush bars resist hair wrap
• Optional Submarine™ wet head for hard floors
• Whole-machine HEPA filtration

Cons

• Premium pricing ($1,349 AUD)
• Slightly heavier than V15 Detect

Dyson’s V16 Piston Animal ushers in a new generation of cordless cleaning. Its 900 W Hyperdymium motor produces a staggering 315 AW of suction — more than many uprights. The CleanCompaktor™ bin compresses debris to fit more in before each empty, cutting maintenance frequency.

Two anti-tangle brush bars handle long hair and pet fur effortlessly, while the optional Submarine™ wet head lets owners vacuum and mop in one motion. Together they make the V16 Dyson’s most versatile system to date.

The LCD screen reports particle size, suction level and runtime in real time. In Eco mode, the 70-minute battery life covers large homes, and HEPA filtration ensures expelled air is cleaner than what entered.

Despite its strength, ergonomics remain excellent. The wand and handle are balanced, noise levels moderate and transitions between carpet and tile seamless. The only drawbacks are price and slightly higher weight — small trade-offs for its leap in power.

Summary: The most advanced and powerful cordless Dyson ever made.
Best for: Power users and households seeking all-in-one deep cleaning.

Dyson V15 Detect Absolute

Pros

• 240 AW suction with auto-adjusting piezo sensor
• Laser Slim Fluffy head reveals microscopic dust
• Whole-machine HEPA filtration
• Clear LCD particle display
• Lighter and more manoeuvrable than V16

Cons

• Smaller bin; no compaction system
• Shorter runtime

The Dyson V15 Detect Absolute remains a cornerstone of cordless design. Its green laser illuminates dust invisible to the naked eye, guiding precise cleaning. Behind that showpiece lies serious engineering — a 240 AW motor coupled with an adaptive piezo sensor that increases suction when particle counts rise.

HEPA filtration captures 99.99% of microscopic allergens, while the LCD screen quantifies debris in real time. The result is a uniquely transparent cleaning experience that shows you measurable results with each pass.

At up to 60 minutes of runtime, the V15 covers most homes easily, and its lighter build improves comfort during long sessions. Owners praise its balance of power and weight, noting that its laser visibility often encourages more thorough cleaning.

Although it lacks the dust-compressor and wet-head options of the V16, it remains one of the most capable and satisfying vacuums available in 2025 — particularly for those wanting flagship performance below four figures.

Summary: The perfected classic — efficient, visible and powerful.
Best for: Allergy-sensitive homes and users wanting precision without overspend.

Shark PowerDetect Clean & Empty (IP3251)

Pros

• Auto-Empty dock reduces dust exposure
• DuoClean Detect cleans on push and pull
• Strong value with intelligent dirt sensing

Cons

• Runtime claims hinge on Eco/handvac testing
• Newer platform with durability still maturing

Shark’s PowerDetect Clean & Empty leans into automation. The included Auto-Empty dock both charges and empties the dust cup into a sealed bag, dramatically reducing hands-on maintenance and allergen exposure. For busy households, this “clean-and-forget” experience is the feature that makes cordless feel truly modern.

On the floor, Shark’s DuoClean Detect head uses twin brush rolls to maintain contact on carpet and hard floors, picking up fine dust and larger debris in a single pass. Dirt-sensing logic boosts suction when load increases, which helps reduce repeat passes and improves time-to-clean.

Battery claims of up to 70 minutes apply in Eco mode and typically without a motorised tool; in real homes with the main floorhead, you should expect less. That said, Shark’s platform balances pickup performance with practical convenience, and its compact dock is easier to place than some tower systems.

The brand’s recent strides in build quality and head design are notable, even if long-term durability is still being proven. For many families, the combination of auto-empty convenience, solid pickup, and approachable pricing hits the sweet spot.

Summary: The best blend of automation, value, and real-world convenience.
Best for: Households that want hands-off bin emptying without paying a premium.

Samsung Bespoke Jet AI (VS28C9769QG/SA)

Pros

• All-in-One Clean Station auto-empties while charging
• AI Cleaning Mode tunes suction and brush speed
• Elegant design with SmartThings integration

Cons

• Max quoted runtime requires two batteries in low power
• Premium pricing close to Dyson tier

Samsung’s Bespoke Jet AI is the polished, design-forward take on automation. The All-in-One Clean Station conveniently empties the vacuum’s bin into a bag each time you dock, while simultaneously charging the battery. This reduces airborne dust and keeps the process neat, especially for allergy-prone users.

AI Cleaning Mode uses sensors to assess floor load and air pressure, adjusting suction and brush speed on the fly. In practice, that means you can move across different floor types without fiddling with settings — a quality-of-life upgrade that feels subtle but meaningful over time.

Samsung quotes up to 100 minutes of runtime in ideal conditions (minimum power, non-motorised tool, dual batteries). Real-world use with the motorised head will be shorter, but the platform remains competitive — particularly for buyers who value app reminders, maintenance prompts, and tight SmartThings integration.

Fit and finish are among the best in the category. If you want an auto-empty stick that looks as good as it cleans — and you’re already in Samsung’s ecosystem — the Bespoke Jet AI stands out.

Summary: A sleek, smart, auto-empty stick for connected homes.
Best for: Design-focused buyers and SmartThings households.

Miele Triflex HX2 Cat & Dog

Pros

• Patented 3-in-1 layout (upright, stick, handheld)
• High-grade filtration; Sensitive Choice approved
• Robust build quality with pet-focused tools

Cons

• No auto-empty dock or app integration
• Suction trails the newest flagships

Miele’s Triflex HX2 Cat & Dog remains a favourite for pet owners and allergy-sensitive households. The 3-in-1 architecture lets you reposition the motor unit low for easier handling on floors or high for quick handheld tasks. That flexibility makes it feel like multiple tools in one.

Miele prioritises air quality. Its filtration system, build materials, and seals are excellent, contributing to cleaner exhaust air — a difference you notice most in smaller or closed rooms. The included pet hair tools and turbo brush are designed to resist tangles and lift embedded fur.

While its raw suction is a notch below Dyson’s latest numbers and you won’t find an auto-empty ecosystem here, the HX2 compensates with sturdy construction and a dependable feel that ages well. It’s the “buy it and keep it” option of the group.

If you value classic ergonomics, reliable pickup, and a filter-first philosophy, the Triflex HX2 continues to deliver in 2025 without chasing specs for their own sake.

Summary: Durable, filtration-focused stick with thoughtful ergonomics.
Best for: Pet households and users who prioritise cleaner air.

LG CordZero A9T-ULTRA / A9X-AUTO2 (All-in-One Tower)

Pros

• Dual batteries enable marathon sessions
• All-in-One Tower auto-empties and stores accessories
• Power Drive Mop adds light wet cleaning on hard floors

Cons

• Tower dock has a large footprint
• Turbo mode runtime is short

LG’s CordZero A9T-ULTRA / A9X-AUTO2 targets endurance and organisation. Two swappable batteries are included, effectively doubling cleaning time for larger homes. The All-in-One Tower charges, auto-empties, and neatly stows a generous accessory kit so everything is ready to go.

Pickup performance is strong in normal modes, and the Power Drive Mop attachment brings light wet cleaning to sealed hard floors — useful for kitchens and entryways. If your home is mostly hard surfaces, the mop head meaningfully reduces how often you need a separate mop.

The trade-offs are size and turbo stamina. The tower’s footprint won’t suit minimalists, and while Turbo is punchy, it drains quickly. Fortunately, the dual battery system cushions that drawback and makes the platform practical in day-to-day use.

For families that value long sessions, tidy storage, and versatility over pure headline suction numbers, LG’s CordZero package is an easy recommendation that competes on real-world convenience.

Summary: The runtime and accessory champion with smart storage.
Best for: Large dwellings and mixed-floor households.

Samsung’s Bespoke Jet AI satisfies those chasing AI-driven intelligence and design polish, while LG’s CordZero A9T-ULTRA dominates for runtime. Miele’s Triflex HX2 Cat & Dog holds firm as the durability and filtration champion.

Choosing the right cordless vacuum now comes down to priorities rather than compromises. Whether you seek raw power, automated disposal, or timeless reliability, this year’s models deliver unprecedented variety and performance.
