LG CordZero R9MASTER Questions & Answers

Mine did the same got it sent away. Battery is most likely stuffed

I am about to take legal action against LG and this is one of the things I will be raising with them.

They never provided me with any paperwork of what services they performed on my vac, if any. Then they told me they don’t want anything to do with refunding or fixing it after the 3rd time and video footage. Never buying LG again

Mate I have German Shepard, short hair and R9 is useless. Dirt inlet port is way to small for anything but dust. Just clogs up. Big regrets with this machine

Hi Barry, have you got the vac on the edge cleaning mode or the zigzag mode? If you have the vac on the edge cleaning mode, it should get right up to the kick panel so long as the cupboards are not preventing it from doing so. However, if you use the edge cleaning mode the vacuuming will take longer but will be effective. I usually leave it on the zigzag mode and clean up the edges and areas that were inaccessible to the vac with my vac stick. Hope this helps.

Thanks Cianna. It’s on edge mode. It stops about 150mm short from the edge. The vac is working fine it must see the cupboard as a obstruction because it is below 143mm from what sticks out from the kick panel. But the cupboard only sticks out about 70mm but the vac stop about 150mm away. Just wanted to know if there is a way to get it closer. It only takes 5 seconds to clean up the spot with the vac stick which I’ve been doing. The robo vac does such a good job around the rest of the house I’m just getting lazy haha.

Thanks

My one had the same problem.. my resolution was using a dustpan and brush and sweeping it myself until I got a new vacuum.

Exactly the same issue. On edge mode doesnt clean the kitchen well enough. It could help if it changed the direction. But it goes in long vertical moves all the time and doesn't reach under kitchen cupboards.

Hi Robyn, sorry but I think you'd need to speak to someone at LG or Harvey Norman as I have no idea. The cleaner won't map the house. I've tried a few times and it fails every time so I don't know about the programming. I can't program it when the useless thing won't do the map to start with. As for the consumable parts, that's another question for LG or Harvey Norman. Sorry. All I can help with is an honest opinion of this cleaner and it's useless. For something so expensive I'd expect a lot better than something that dies all over the house, won't map, won't return to base most times to charge, cleans the same room over and over and over and ignores the other rooms. OMG, it's rubbish!

Thanks for your honest review. I'm coming off a very frustrating similar situation with another brand of robotic vacuum. Returned the first one coz I thought I had a lemon only to find the second one is doing much the same useless things. Thought I'd try a different brand but maybe they're all just rubbish.

Hi Robyn, I had huge problems with the Samsung Powerbot VR9300 and finally received a full refund after 8 months. Consequently, I was very careful when purchasing the LG and did a lot of research including e.g., external link  and so far I haven't been disappointed. I have found that the LG vacuums over rugs that have black in the pattern with no problem whatsoever because the sensors can differentiate between stairs and black/dark carpets/floors (something the Samsung couldn't do). The LG also mounts a small step into our ensuite with no problems. In 8 months of vacuuming our large single-storey home it has got stuck twice when it wedged itself between the toilet and wall. Initially, I did supervise the LG for a while to ensure that it cleaned the whole house but later found that where the LG has cleaned can be viewed from the app on the smart phone. After the LG had mapped the house it settled into a cleaning pattern and cleaned all of the rooms. I was quite amazed when I watched it clean our gym room. It wove in and out of the equipment without an issue and cleaned all of the accessible areas well. If the whole house isn’t fully cleaned because the battery is low the LG returns to base to recharge then resumes cleaning from the previous spot. It is important to allow the app to update regularly and always empty the dustbin and clean the brush-roller and filters regularly. Also, always start the LG from the base otherwise it might not find its way back home. If I had any unresolved issues with the LG it would be returned to Harvey Norman post-haste after my bad experience with the Samsung Powerbot VR9300.

Hi Cianna, thankyou for your reply. I did infact purchase the LG R9 Master as well in the end. But I'm not happy with it for the price. Sometimes it will start a clean which should take it 2 cycles of the battery to complete with recharging inbetween, however it will "think" it's completed the whole clean after 10 minutes of it leaving the base station. Plus I still have issues with it trying to throw itself off our stairs. Not so much when it's facing forward but it will spin itself around and try to go off backwards, which makes me not confident to leave it running without supervision as I'm not prepared for a machine this expensive to end up at the bottom on the stairs. We always do the updates. It always starts from the Base Station. I just think for the money it is just a waste and I'm sorry I purchased it.

Hi Robyn, I only just read your reply to my message. If I were you I would take the LG vac back, if you haven't already. It's too expensive to be landed with a 'lemon'. I had similar problems with the Samsung Powerbot and after it was finally inspected I was told that the computer that controls the vac was faulty from the beginning and would never have worked. Now I'm wondering if that particular component is used in other robot vacs:>( As far as my LG vac is concerned, so far so good. Time will tell:>)

RoboRock S7 Max is the best - it’s cleans and mops, worth every penny spent I have 2 off IRobot s9+ they were working fine after 2 years started error messages including bag full error even it’s only a quarter, then have to reboot it multiple times and clean the sensor.

LG R9 is the worst among the lot. Terrible battery, never return to the base, cannot clean, it’s a lemon - I have to service it every 4 months - I took the product care I think it’s a scam when comes to LG products.
