AI Verdict
This 5.6-pound cordless vacuum with 115 AW suction and 40-minute runtime is for quick cleanups in smaller homes with pets.
This vacuum is a situational fit, offering 115 AW of suction and a lightweight 5.6-pound design that's great for quick, targeted cleaning. However, its limited 5-minute Max mode runtime and small 0.14-gallon dust bin mean it's not ideal for extensive cleaning tasks.
If you need longer high-power runtime or a larger dust bin for bigger homes, look for models with higher AW ratings (e.g., 185 AW+) and capacities above 0.2 gallons.

Pros
- Weighs 5.6 pounds, making it easy to maneuver for quick tasks.
- Motorbar cleaner head automatically detangles long hair and pet hair as you clean.
- Effective at picking up fine debris and pet hair on carpets and hard floors.
- Converts to a 5.6-pound handheld vacuum for cleaning cars, stairs, and upholstery.
- Whole-machine filtration captures 99.99% of particles as small as 0.3 microns.
- Dust bin empties hygienically without requiring you to touch the dirt.
Cons
- Battery lasts only 5 minutes in Max mode, or 8.5 minutes in tested conditions.
- Small 0.14 Gallon (0.53 L) dust bin requires frequent emptying.
- Pushes larger debris around on hard floors with its standard cleaner head.
- Battery is not easily swappable, requiring tools for replacement.
- No trigger lock, so you have to hold the power button constantly.
- Lacks LED lights on the main cleaner head, making it harder to see dirt in dim areas.
Dimension Scores
The 115 AW suction is adequate for fine debris and pet hair, but performance drops significantly on low power, and it struggles with larger debris on hard floors.
Its 5.6-pound weight and ability to convert to a handheld make it maneuverable, but the small 0.14-gallon bin and lack of a trigger lock are notable drawbacks.
The plastic construction can feel somewhat fragile, though filters are washable and batteries are replaceable, albeit with tools.
The 'up to 40 minutes' runtime is misleading, as Max mode only lasts 5-8.5 minutes, and performance on the longer-lasting low mode is significantly reduced.
Best For
- Quick daily cleanups on hard floors and low-pile carpets.
- Homes with pets for efficient hair removal.
- Cleaning cars, stairs, and upholstery using its handheld configuration.
- Small to medium-sized living spaces where portability is key.
Not Recommended For
- Large homes requiring extended high-power cleaning sessions.
- Frequent deep cleaning of high-pile carpets.
- Picking up large debris on hard floors without a specialized soft roller head.
Watch Out For
- The advertised 'up to 40 minutes' runtime is only with non-motorized tools; with a motorized head, it's closer to 30 minutes, and Max mode provides only 5-8.5 minutes of power.
- The dust bin capacity is 0.14 gallons (0.53 liters), meaning you'll be emptying it frequently, especially if you have pets.
- While it detangles well, some longer hair (14-inch) can still tangle around parts of the cleaner head, making it difficult to remove.
- Replacing the battery isn't a quick swap; it requires a screwdriver to access and remove.
- You have to keep the trigger pulled down the entire time you're vacuuming, which can make your hand sore during longer sessions.

What Buyers Say
Many users are genuinely surprised by how much dirt and pet hair this vacuum pulls up, even from seemingly clean areas, making it feel like a significant upgrade from cheaper alternatives. Its lightweight design and ability to convert to a handheld make it super convenient for quick daily tasks and cleaning various surfaces like cars and stairs. However, the short battery life, especially in Max mode, and the small dust bin are recurring frustrations that users frequently point out. Some also wish for a trigger lock and better handling of larger debris on hard floors.
“OMG, this thing actually sucks up SO much dog hair, I thought my floors were clean! But the battery dies so fast on high, I can barely finish the living room. Still, it's so light, I guess I'll just charge it more.”
Common Praise
- Picks up a surprising amount of embedded dust and debris from carpets, even when they look clean.
- Lightweight (5.6 pounds) and easy to maneuver around the house, making quick cleanups less of a chore.
- Effective at picking up pet hair with the Motorbar head, preventing tangles.
- Convenient for quick, everyday cleanups and easily switches between floor and handheld modes.
- The wall-mounted dock makes charging and tool storage simple and tidy.
- Hygienic bin emptying prevents contact with dirt, which users appreciate.
Common Complaints
- Battery life is too short, especially when using Max mode (5-8.5 minutes), often not enough to finish a larger area.
- The 0.14-gallon dust bin fills up quickly, requiring frequent emptying during cleaning sessions.
- Pushes larger debris on hard floors instead of picking it up, necessitating multiple passes or lifting the head.
- No trigger lock means you have to hold the power button down constantly, leading to hand fatigue.
- Longer hair (14-inch) can still tangle around the brush bar, making it hard to clean out.
- Some users report the plastic construction feels less durable than expected for the price.
Ownership Tips
- The battery typically lasts about 4 years before needing replacement, which can be done with cheaper, non-Dyson alternatives found on Amazon.
- Filters need occasional cleaning and replacement, but new ones are inexpensive and readily available.
- Dyson provides online videos that are helpful for deep cleaning clogged areas and performing routine maintenance.
- Holding the trigger for extended periods can make your hand sore, especially during longer cleaning tasks.

Buying Guide
When looking at cordless vacuums like this, you need to think about how you actually clean. Are you doing quick daily passes or deep cleaning your whole house? The 'up to 40 minutes' battery life is a bit of a trick; you'll get way less if you use the powerful modes or motorized attachments. Also, consider the dust bin size – a small one means more trips to the trash.

Alternatives
If this isn't enough power or runtime, look for models with higher AW ratings (e.g., 185 AW or more) and larger battery capacities for extended use, or consider models with easily swappable batteries.
