Best praise vs top criticism for LG CordZero A9 Kompressor
“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.”
