The LG CordZero A9 Ultimate is a high-end cordless stick vacuum that made its debut in 2019, promising portability and effective performance on both hard floors and carpets. It has a sleek charging station that doubles as a storage rack. This vacuum has a HEPA filter that traps up to 99.97% of allergens and small particles down to 0.3 microns.


Shipped with two detachable battery backs and a docking station, this unit provides convenient cable-free performance. Browse to the end of this LG CordZero A9 Ultimate review and see how this vacuum stacks up against the top rated vacuum cleaners on the market today.

Reasons to Buy

  • Outstanding performance on bare floors and low-pile carpets
  • Two detachable battery packs
  • Excellent pet hair removal rate
  • Lightweight design with a detachable handheld pod
  • HEPA filter
  • Two-in-one docking and charging station

Reasons to Not

  • Small dust cup
  • High-maintenance design
  • So-so performance on high-pile carpets

Market Context

Compared to the same brand’s similar models: The LG CordZero A9 Ultimate is almost identical to the LG CordZero A9 Kompressor. The only difference is that, unlike the Iron Grey A9 Ultimate, the A9 Kompressor has a Vintage Wine color palette and comes with two sets of washable filters instead of one.

Compared to other brand’s similar models: Unlike the LG CordZero A9 Ultimate, the Dyson V11 Animal comes with a hard bristle brush, and it performs better on high-pile carpets, removing 62% of the large debris particles, compared to the 53% removal rate of the LG. However, unlike the Dyson vacuum, which comes with one battery, the LG features two removable batteries, offering potentially infinite battery life.

Equipped with a turbo brush, the Samsung Jet 90 Complete performs better on high-pile carpets (75% large particle removal rate) than the LG CordZero A9 Ultimate (53% large particle removal rate). However, the LG runs for longer (74 minutes) than the 61-minute battery life of the Samsung vacuum.

Critic Consensus

Critics lauded the LG CordZero A9 Ultimate and endorsed it for bare floors and carpets. It removed an outstanding 100% of the large debris from bare floors and 83% on low-pile carpets, producing up to 0.85 kPa of suction power. However, it performs dismally on high-pile carpets, removing just 53% of the large debris during testing.

See the Miele Triflex HX1 review for a model that performs better on high-pile carpets. Reviewers from Choice were happy that it has a HEPA filter and it prevented dirt from leaking during air quality tests. Weighing just 6.06 lbs, this unit proved portable during experiments. Analysts at Product Review hailed its relatively low 71.0 dBA noise level and two detachable battery packs that yield a combined total of 74 minutes of battery life.

However, if you desire longer runtime, check out the LG CordZero A9 A916BM review, which runs for up to 112 minutes. Experts were unimpressed by its small 0.35L dirt compartment.
