LG CordZero R9MASTER

This has not cleaned properly since day 1. We have had an LG Roboking previously which worked well and cleaned corners really well. We bought this based on the assumption it was the most expensive and therefore better quality, however we wee sorely mistaken. It has been garbage, never finds its way back to the home station. We were told to do the firmware upgrade which has actually made things worse and the cleaner does not know where its going. Will be going to consumer protection as this is clearly not fit for purpose, unless the purpose is a $1400 paper weight.

We have had a Samsung robot vac previously and were very happy but it was time for an upgrade. We bought this as it has HEPA filtration due to kids with allergies but also because it claims to map areas and rooms in your house. This means if the kids have toys on the floor I should be able to tell the vac not to go in that room today. Unfortunately we have had this for 12 weeks now and the mapping function does not work. Most of the time it does not go into my daughters room (the one that needs it the most due to severe allergies) and on the odd occasion it does then it won't go into my sons room. In 12 weeks it has not been able to successfully map and clean both rooms on the same day. I reported this to LG within days of owning it. After being passed are departments to various people that could not help I was told someone would call me. After several follow ups and emails they requested photos. I still don't have a vacuum that does what it claims to do and doesn't go into all my rooms. I even have a video of it goi g into my sons room part way and turning arou d for no reason and leaving the room. The suction is great, the Hepa is great I just wish it would map as its advertised to do and recognise all rooms on the same day.

Intelligent and powerful robot. Suction power is as good as stick vacuums. Unlike its predecessors or competitors, this robot rarely gets stuck or lost. Capable of mapping all rooms in your house for cleaning only specific areas. You can control it through your mobile phones or google assistant. Worth the price.

This was the most expensive robot vacuum cleaner in the store and I was told it was great. Hmmm. I've had a few problems setting it up (i.e. setting the correct time, scheduling a cleaning time) and trying to speak to anyone at LG's Service Centre is impossible. They're hopeless! I even asked the Harvey Norman store where I bought the cleaner to ask their LG rep to call me. I was told this would happen. Three weeks on and still no call.
The cleaner goes over the same spot continually instead of cleaning the entire house. Often it just stops where it is and doesn't go back to the charger. It will clean part of the house and IF it does go back to the base station to charge it's then supposed to pick up where it left off and clean the rest of the house. This rarely happens. Cleaning quality is good but I've found it does miss a lot of spots around furniture where my Roomba cleaner would get everything.
Summary: It's definitely not a great cleaner and not worth the high price tag. I wouldn't recommend it. If I didn't have new dark carpet that my Roomba won't clean on (due to the cliff sensors) I'd never look at any other brand besides Roomba. This LG R9 is a waste of money. Very disappointed at both the cleaner and also the lack of customer service from LG. I wouldn't buy another LG product that's for sure.
