LG CordZero R9MASTER

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.

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. 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 time...

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 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.

I’ve had this for 6 months. It was getting stuck under couches, against walls and smashing into things in our (10 month old house). Contact LG, it goes off for repairs, it’s gets parts replaced but they claim there was nothing wrong with it...huh?!

I was told by LG before they repaired it that it would be replaced...wrong.

Fast forward a month, they apparently ‘fixed it’ but they say there was nothing wrong...anyway, I told them I wanted the casing of the machine replaced as it looks like it’s 10 old machine. They have refused to replace it s...

Terrible. If I could give zero I would. We were so happy with our previous roboking but this thing is useless. we have had nothing but trouble with it. Took it back to Harvey Norman Malaga(Manager was beyond rude and dismissive) They sent it away to LG and it came back weeks later saying there was no fault. Now 12 months on its even worse. Wont charge, doesnt turn on and when it does it turns off 2 minutes in. We have run diagnostics but you cant smart diagnose it as the battery is dead?! Useless, and just want our money back to purchase a product that does the job, as for $1600 I would expect a working fit for purpose product, and not this very expensive door stop.

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.
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.

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

I have been using it for a year now. The battery still can last for 2 hours each time. It is clean like the normal vacuum cleaner. I always put all the chairs next to the wall so it can clean under the chairs and table easily. It can be set up to clean all the edges that other round robot vacuum cleaners cannot do. I highly recommend this product.

My Review of the LG-R9 Master Robot vacuum cleaner.

I set up wifi & mapping, opened all doors, removed any obstacles e.g. fluffy bathroom mats, & the LG-R9 entered & cleaned every room without issue, producing an initial map that it updated each time it cleaned. To be fair, the mapping is best after about 3 excursions as it intelligently improves the mapping. We have fitted textured wool carpet, heavy traditional rugs in some areas with black edges (which my returned Samsung Powerbot couldn't touch) 1 shag pile rug & lots of tiled areas. It ev...

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 od...

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 st...
