Verdict

The LG CordZero A9K-PRO1G is a 200-watt cordless stick vacuum powered by a Smart Inverter Motor and an Axial Turbo Cyclone system, weighing 2.7 kg and featuring a 5-step HEPA filtration system. Main pros include its Dual PowerPack system with two interchangeable lithium-ion batteries that deliver an impressive combined runtime of up to 120 minutes, a 4-level telescopic tube, ThinQ Wi-Fi connectivity, and integrated Kompressor technology that compacts dust and hair to effectively increase the 0.44-liter bin capacity by up to 2.4 times. On the downside, the vacuum requires a 3.5-hour charge time per battery, lacks a removable handheld option, can struggle to pick up large debris like cereal on hard floors, and is reported to have a relatively high noise level of up to 84 dB when operated in its maximum turbo suction mode.

Summary of the review

Cordless and Canister Vacuum Cleaner Test - Konsument

The joint testing by Konsument and Stiftung Warentest shows that while top-tier cordless vacuums now match corded models in general suction power and offer superior handling, they still struggle with deep dirt extraction in carpets and short runtimes at max power. Conversely, corded vacuums remain the better option for heavy-duty cleaning due to their consistent, uninterrupted performance and quieter operation. Premium cordless models, such as the Bosch BSS series, are praised for versatility, but, generally, battery-operated units have higher noise levels and lower cleaning capacity on carpets compared to traditional vacuums.

LG CordZero A9 Kompressor ThinQ: cleans, mops and eliminates up to 99.99% of particles

The LG CordZero A9 Kompressor ThinQ is described by Il Corriere della Sera as a premium, versatile vacuum that effectively vacuums, mops, and filters allergens, featuring a unique Kompressor lever to double dirt capacity and a 120-minute dual-battery system. While praised for its superior suction and ergonomic handling, the review notes the high price and the added weight of the mopping attachment as primary drawbacks.
