LG CordZero R9MASTER

Useless After 2 Years! – Purchased for approximately $1400 from Harvey Norman in 2021 for use on carpet and tile floor. Worked flawlessly for two years…..then the problems started. Robot leaves dock then turns off and back on after about 30 seconds and just sits there. Diagnostic reports no problems. I suspect battery charge is depleted even though it reports fully… Read more

charged. For the price I expected at least a 5 year life - will avoid all LG products from now on! Buyer beware!

Do NOt Purchase Its waste of Money – I purchased this inR9 Master in 2020 in about 6 months it kept going in circles and made a huge mark on my wooden floor..I took it to a Vaccum Appliance Store under Lg instructions...They said there was nothing wrong with it..I started using it again and in another 6 months it has totally died and does not work.. LG said now it is out of its 2… Read more

year warranty and nothing they can do. I will never buy from LG again as their product did not work well and they were terrible with support both times around.

Over priced and waste of money!! – Brought the LG CordZero R9MASTER from Harvey Norman when we moved into our new home. Only operated for 12 months before the machine stopped working. When you turn it on it says ready to clean but when you hit start it states the battery is low. Given up. LG Customer WARRANTY service in Australia sucks!! The Cord Zero vacum cleaner also crap its… Read more

self and also a waste of money. Stick with Dyson!!!! I dont know how the government allows these companies to get away with poor warranty service? At the time our Harvey Norman invoice for LG products was over $17000. LG only makes good TV'S and nothing else.

Wouldn't buy an LG robot again – The bristle head stopped spinning after 1 Year got replaced under warranty. Continually gets lost an runs out of battery. After 2.5 years of owning it and out of warranty. It leaves the dock and immediately shuts off all power. Cant find any repairers who repair robot vacuums. Cant find parts online and LG authorized service repairer doesn't exist anymore. Had good features but poor longevity Show details

Need to improve battery quality, no warranty on replacement battery's, beware of ongoing costs – Need to improve battery quality. First one and second failed at 23 months. First under warranty, second at a cost of $400. Please note there is no warranty on new genuine battery's installed by LG recommended repairer. Spoke to LG direct and was told three months on replacement parts. Understand that the maintenance cost on this unit is $200 per year as you will wont get two years from a battery. Show details

Always clogs on carpet lint and it needs a full disassembly to fix – We have a new apartment with the bedroom carpeted. I thought the first few rounds would be a bit 'lintty' but it fills up in no time then just keeps going, with no alert or warning, before getting clogged from the head to the dust bin and needs to fully disassembled for unclogging. I could vacuum the house manually in the same time.  Show details

Issues resolved by support team! – I've the L9 RoboVac for around 4 months, initially it worked well with the exception of not mapping the house - very few obstacles as its a new house. i ended up doing a hard reset on the device and it worked perfectly, mapped the house, didn't go into specific rooms that were turned off and i had no issues recommending it to friends and family.… Read more ·  1

BUT...there has recently been an update to the software and it has been useless ever since, won't go through the entire house, not mapping, scuffing skirting boards, going over the same rooms three times, constantly bumping into walls, objects etc. i was wrapped when this started doing what it was supposed to but since the update (and I've done a hard reset again) its a waste of money and i have no choice but to take it back. *EDIT* Credit to the LG support team, I received a couple of emails asking about the specifics of the problem and then received a phone call to go through some trouble shooting. It's working great again now and I'm very impressed with the support I received!!

Don't buy it unless you want to waste your money and energy – It's tile flooring. It worked perfectly for 18 months but started not suctioning and dust stuck in the entrance of the vacuum and the dustbin. Been repaired 3 times over last 9 months. First time, not repaired at all. Second one, been repaired and worked better but not as great as a new one. After a few months, showed same issues again then sent… Read more

away. Finally, requested for the refund but they refused because the issues caused by user errors. They said I lost dustbin seal. Good luck if you still want to purchase this.

Doesn't clean corners and edges as well as Roboking did – Comparing to old LG Roboking this robot definitely is smarter, suction power on carpets is amazing, navigation - good enough, it's almost never gets stuck, what was the main issue with my Roboking. But it was a big mistake to remove rotating brushes from the front in this model. Perhaps its better for carpets but leaves dirt on floating boards. … Read more

Also no attached wipe function anymore, floors looked much better after it. With the price tag almost twice more than my old Roboking, it's quite disappointing.

I feel this was more of a dustpan than a vacuum – it was used on 95% carpet floorings and 5% tiles I find this vacuum was more like a dustpan, However, It is great as a security camera when you’re not home, you can control and see in live view the vacuum from your phone (as long as it is running) . I much prefer a manual vacuum not a robot one. (I don’t use it anymore so it’s just sitting in my cupboard) I wouldn’t recommend this Show details

Very disappointed, want my money back! – 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… Read more

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.

Does not clean entire house – 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.… Read more

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.
