Key Features

  • Perfect Power for Routine Cleaning: A new, more efficient airflow design coupled with our powerful Smart Inverter Motor provides up to 150 AW of suction and delivers all the pick-up power you need to meet your daily cleaning routine head-on. It’s suction power designed to last, with 15 cyclones that separate dirt and debris from the airflow to help keep filters cleaner and reduce clogs that can affect suction performance over time.
  • Automatically Detects Carpet or Hard Floors: Built-in sensors detect carpet or hard floors on the fly and automatically adjust vacuum suction power for each surface. It incorporates both a soft roller and a carpet agitator in one, so you don’t have to fuss with changing attachments to get the deep clean you want. Perfect for pet owners, it easily picks up hair while minimizing messy tangles. Built-in LED headlight illuminates your cleaning path so even in dark corners, dirt has nowhere to hide.
  • Filters Out Dust for Suction Power that Lasts: Our 5-step filtration system helps to filter out dust by separating suctioned dust in the dust bin, then filtering the remaining fine dust. The 15 cyclones help optimize suction power over time by lessening the potential for clogs.
  • Removable and Washable Cyclone, Filters and Dust Bin: Extend the life of your vacuum with easy to maintain washable components that can all be removed with a simple twist—no tools required. Unlike other vacuums that only let you remove the filter, LG CordZero lets you remove the filters, dust bin and cyclone to clean away dirt and keep your vacuum running at its best.
  • Compress Dirt and Dust so You Can Clean More, Empty Less: Press the Kompressor lever to compress collected dirt, dust and pet hair in the bin and create up to two times more bin capacity. Kompressor also lets you easily empty the bin with less scattered dust.

I bought an LG CordZero around this time last year. Two cats and two messy humans in our household. Hardwood floors + a low shag area rug that the cats love to sleep on. It’s a solid machine, on max the suction is quite good and it even has an automatic boost mode beyond that which will kick on if it detects resistance. On medium power, with the power head, the battery lasts about 15 minutes. Good enough for some maintenance work. You might get an hour out of the battery on low power mode, but I think a mouse taking a deep breath has more suction. The cradle is awesome, I love just plopping the vac back in and it gives me a little chime and quietly charges away. The cradle also supports an extra battery, so you can have two fully charged if needed. I did not opt for the one that automatically evacuates the canister - too expensive and complex. I think mine was originally $600 and I got it for half off during Black Friday. Would definitely not pay $600 for one, and my parents gifted us $150 for it so really we paid $150. Got the two year warranty for $1 as well. If you can get a Cord Zero for under $300, it’s a great buy imo.

Not sure if this will help but I can say I bought the LG CordZero. This Reddit tends to lean anti-Dyson and what do I know. So I saw the LG recommended on this Reddit quite a few times…and long story short it is awful. If you find something let me know, but I have many friends and family with a Dyson v11 or higher and they seem pretty darn good, will probably get one soon.
