Cordless vacuums have gone from a novelty to the default choice for most households. No cord hunting, no tripping hazards, no being restricted by the length of a cable — just pick it up and clean. But as the market has grown, so has the confusion around specs.
What does kPa actually mean? Is 800W enough power? Do you really need HEPA filtration? This guide answers all of it — and shows you exactly what to look for in 2026.
The Most Important Cordless Vacuum Specs Explained
Suction Power: kPa vs Watts — What's the Difference?
This is the most commonly misunderstood distinction in vacuum marketing.
Watts (W) measure how much electrical power the motor consumes. A higher wattage means a more powerful motor — but it doesn't directly tell you how much suction reaches the floor.
Kilopascals (kPa) measure the actual suction pressure at the nozzle. This is the number that tells you whether dirt actually gets picked up. A vacuum with 800W and 55 kPa (like the Airglop VG 20 Pro) delivers strong, effective suction across all surfaces.
For context:
-
Below 20 kPa — basic dusting, light debris on hard floors
-
20–40 kPa — general home use, suitable for most surfaces
-
40–60 kPa — deep cleaning, carpet embedded dirt, pet hair
-
Above 60 kPa — heavy-duty or commercial use
The Airglop VG 20 Pro operates at 55 kPa — firmly in the deep-cleaning range, capable of pulling embedded dirt from carpets and fine dust from hard floors with equal effectiveness.
Battery Life and mAh: What You Need to Know
Battery capacity in cordless vacuums is measured in milliamp-hours (mAh). A higher mAh rating means longer run time per charge.
The Airglop VG 20 Pro features a 4,000 mAh battery, which provides extended cleaning sessions suitable for whole-home use without recharging. The charger is included in the box.
Tip: Always check whether the battery is removable. A removable battery lets you buy a spare and swap mid-clean for larger homes.
HEPA Filtration: Do You Actually Need It?
HEPA stands for High Efficiency Particulate Air. A true HEPA filter captures 99.97% of particles as small as 0.3 microns — including dust mites, pollen, pet dander, mold spores, and fine dust particles that standard filters miss.
If anyone in your household has allergies, asthma, or respiratory sensitivities, HEPA filtration isn't optional — it's essential. Without it, a vacuum can re-circulate fine allergens back into the air as it cleans.
The Airglop VG 20 Pro includes a HEPA filter, and an extra HEPA filter is included in the box — so you're covered for replacement without an immediate additional purchase.
Attachments: What Comes in the Box Matters
A cordless vacuum is only as versatile as its attachments. The VG 20 Pro includes:
-
2-in-1 brush — transitions between floor and upholstery modes
-
Flex tube — reaches under furniture, into corners, and car interiors
-
Wall mount + hardware — stores the vacuum off the floor, charged and ready
No additional purchases needed to cover standard household cleaning.
Cordless vs Corded Vacuum: Is Cordless Still Worth It in 2026?
The two main arguments for corded vacuums used to be suction consistency and unlimited run time. In 2026, both arguments have weakened significantly.
Modern cordless vacuums like the VG 20 Pro maintain consistent suction throughout the battery cycle. Battery technology has also improved enough that 4,000 mAh provides adequate run time for most home cleaning sessions.
The freedom of movement a cordless vacuum provides — especially when cleaning stairs, cars, or multiple rooms — outweighs the cord for the vast majority of households.
How to Maintain Your Cordless Vacuum for Maximum Performance
-
Empty the dustbin after every use — a full bin reduces suction pressure immediately
-
Clean or replace the HEPA filter every 1–3 months depending on use frequency — the VG 20 Pro includes a spare
-
Check the brush roll for hair tangles — especially in homes with long hair or pets
-
Store on the wall mount to keep the battery topped up and the unit protected
-
Avoid vacuuming wet debris unless the unit is rated for wet-dry use

Frequently Asked Questions
What is a good kPa for a cordless vacuum? For general home use, 20–40 kPa is sufficient. For homes with carpets, pets, or allergy sufferers, look for 40 kPa and above. The Airglop VG 20 Pro's 55 kPa places it firmly in the high-performance category.
How long does the Airglop VG 20 Pro battery last? The 4,000 mAh battery is designed for extended whole-home cleaning sessions. Exact run time depends on the suction mode used — higher suction settings consume battery faster.
Is a HEPA filter vacuum better for allergies? Yes. HEPA filters capture particles as small as 0.3 microns, including common allergens like dust mite debris, pet dander, and pollen. Standard filters miss these particles entirely, often redistributing them into the air.
Does the Airglop VG 20 Pro work on both carpet and hardwood? Yes. The 2-in-1 brush and 55 kPa suction make it effective on both surfaces. The flex tube and brush attachments extend its reach to upholstery, stairs, and tight spaces.
Is 800W enough for a vacuum cleaner? 800W combined with 55 kPa suction pressure is more than sufficient for home use across all surfaces. What matters most is suction pressure (kPa) at the nozzle — wattage alone is not a reliable indicator of cleaning performance.
Final Thoughts
The cordless vacuum market in 2026 is crowded, but the specs that actually matter are simple: suction pressure (kPa), battery capacity (mAh), and filtration quality (HEPA). The Airglop VG 20 Pro checks all three boxes — 55 kPa, 4,000 mAh, and HEPA filtration — at a price point significantly below premium competitors.
Combined with a wall mount, flex tube, 2-in-1 brush, and an extra HEPA filter in the box, it's one of the most complete cordless vacuum packages available for home use.
