What is a portable vacuum cleaner?

What is a portable vacuum cleaner? A real-world user guide

1. Core definition: A handy, quick-service cleaning tool
Essence: A vacuum cleaner that can be carried in one hand and carried on the go, typically about the size of a thermos cup.
Comparison: ► vs. traditional vacuum cleaners: Like a folding bicycle vs. a car, sacrificing performance for ultimate portability. ► vs. a broom: It's a winner for biscuit crumbs in sofa seams; it's useless for cleaning large areas of floor.

2. Who should buy it?
Poop scoopers: Cat litter and hairballs in the car are quicker to vacuum than to wipe.
Moms/Dads: Food crumbs under the dining chair—just bend over and get them in 5 seconds.
Modelers/Crafters: Wood chips and eraser scraps from your workbench, no worries about blowing away your work.
Business travelers: Stuff your suitcase to clean hotel carpet mites and sleep without itching. 

3. Refreshing Moments
Life-saving Scenarios: ► Overturned milk powder can → Vacuums clean in 10 seconds without getting your hands dirty ► Necklace falls between sofa cracks → Remove the flat nozzle for easy recovery ► Dust-covered keyboard → Use the brush nozzle to refresh
Secret Advantages: ** Library-level quietness (sneaky vacuuming your desk during a meeting won't make you look bad) ** Stress-free security checkpoints (battery < 100Wh allows for airplane use)

4. Moments When You Want to Blame
Battery Life Scam: Claimed 15 minutes ≈ 5 minutes on high (power cuts out halfway through vacuuming car seats).
Suction Power Mythology: It picks up paper scraps, but can't pick up pet food deep in the carpet.
Dust Bin Trick: Emptying the dustbin creates dust, making cleaning the car akin to creating a sandstorm.
Missing Accessories: The flat nozzle disappears after three uses; buying it separately from the official website is 1/3 the price of the device.
