Purchased my VR20K9350WK/SA just over two years ago and hardly used it but we’ve just moved house and on paper it should be a perfect fit, big open spaces and easy transitions from carpet to tiles. In reality it was pretty rubbish. Whilst it’s powerful the mapping feature is practically useless so you can forget about using that feature to select a specific room to clean.
After using it for about 3 days in the new house it started to play up. Started going round in circles and then completely lost the plot. Going backwards at high speed and gi...

Frequent breaking:

1 year in: One of the two spring-suspension wheel's suspension gave way. Noticed it because it kept on getting stuck trying to climb a thin rug. Replaced under warranty.

The unit made a horrible noise when turned on, just after the 2 year warranty expired. Turns out, the gearbox for the rotating brush is house in plastic. As the gear spins, the plastic housing melts/breaks, which meant that one of the gears was spinning out of control, instead of in one place. Took it to service centre, and they charged me hundreds of doll...

Would give 0 starts if I could
Misses vacuuming areas
Does not work on carpets
Mapping is useless, bangs around
Keeps getting stuck with its rear up on walls
Watch the battery drain while it continues looking for its dock
Battery does not last

The vaccum cleaner is a great product, though very expensive. What you are not told is that the cost of the replacement battery is $399; it lasts about a year depending on usage.

Over the past 8 or so years, I have owned 4 Samsung robotic vacuum cleaners, including, most recently, this one. The first two just stopped sucking, the third just died and this one has motion sensor issues + a component in the wheel is broken (so it turns around in circles and thinks it is running into something when it isn't). I attempted to get assistance with Samsung but was ordered to obtain my proof of purchase from where I purchased the vacuum. JB Hifi do not have my proof of purchase so a vacuum I purchased just over 2 years ago for $2500 is now defunct and ready for the bin. Won't be wasting my money on any more Samsung vacuums and will be urging anyone that will listen not to opt for a Samsung robot vacuum

This vacuum started out okay - only okay -
Mapping never seemed to work - bangs into chair legs, would work over the same area and miss other areas. Constantly doesnt make it back to the doc - spends more time looking for it than acutally vacuuming.
One of the wheels lost its spring - how that ever broke I do not know - No kids in the house so cannot blame them. Charger broke - paid $250 for a new battery - which is not covered under warranty - then whole machine just broke. Into the repair shop -
3 weeks later no answer they were waiting ...

Unit works well - we have a tile floor, and its quite good for that. Having said that, we had not used our unit for some time as we used to have cleaners come in as well. Now, having to use it again to a change of circumstances due to COVID-19, the battery seems to have packed up? It says full charge on the dock, but when you turn it on, it only moves 1 cm away and dies?!

There's no warning on stuff like this that a. the battery will die, and b. on top of the $2k for the unit, the battery is going to cost you another $400 to replace - without even a techie looking at it..

Not value for money Samsung!

After using this unit for roughly a year, and being completely happy, the battery started not charging. I tried to use the forums to fix as per Samsung instructions, then I took the unit into the authorized repairer. They said the battery would need replacing for around $300. I tried to get Samsung to help, but after hearing nothing for 2 weeks, they simply said the battery is only under warranty for 6 months. We paid $2k for this unit, and it is now worthless?! I do not recommend this unit at all!

As an update, after posting a couple of revew...

This is my dream come true. And worth every dollar. We use it upstairs and downstairs on carpet and tile and the mats we have scattered around the home. It saves me hours of vacuuming time that I can spend with my daughters. Great on pet hair too. Excellent and throughout clean. Easy to set up and easy to use. Very easy to clean and empty. Transitions well from tile to carpet and moves around objects easily as it has a sensor. Powerful suction, I love that I can control it from my phone even if Im not home. Love it.

I do like the unit but had to have warranty work done, then just outside of warranty the barrier device stopped working, and now the battery needs replacing and will cost $250 to replace. For the price paid I don’t feel like it was money we spent. I am contemplating if perhaps buying a cheaper branded unit annually is a better financial decision that fixing this unit.

This is the second robot vac we have had & far better than the earlier model. It has exceptional suction & (unlike the other) hasn’t missed a beat. Highly recommend this unit

This thing has needed constant repairs and replacements and visits from technicians since the day be bought it. Still has connection issues, and the "smart" mapping feature needs a lot of work; I haven't even been able to use this feature at all since purchasing the unit over a year ago because it's rubbish. If this product stops working again once our warranty is finished, we will be chucking it in the trash. The biggest waste of time and money.

My power bot has been in repairers since April 2019.now in retailers waiting for response from samsung have communicated with Jo today it seems they don't have access to my complaint,haha .It seems like they don't want to deal with the problem. Not happy next step is current affairs

Definitely saves time and effort from hoovering, great to leave on when you need to do other chores / leave the house however doesn't perform the best clean (occaisonally missing areas of the house) and is definitely over priced. Would suggest to wait until tech improved / cost reduced.

I bought this Vacuum on 17/12/2017 it is now 26/04/2019 and it has been in for repair on 5 separate occasions, I have just been told that the battery needs replacing and it only has a 6 month warranty so I have to pay $240 for a new battery, I would not recommend this to anyone.

Have had it for just over two years and in that time has broken down four times and required new batteries, new chargers, etc. This is the most unreliable piece of consumer electronics we have ever purchased. The unit does actually work fairly well but I reckon we've spent more than 8 hours driving to and from service centres and trying to fix the thing.

The machine does what it’s supposed to do, vacuum the floor but so do all vacuum cleaners! The User manual is designed for people who can extrapolate technical instructions because it doesn’t tell you much about Features and it’s very basic, it says things like “start button starts the Robovac, right button turns Robovac to the right” we all can understand the the basics but I’ve found that even when the machine doesn’t perform properly the error codes don’t show up and there’s quite a few in the manual but they never show up on the machine. I ...

I would NOT buy ANY samsung Powerbot. I purchased the top of the line 2 1/2 years ago for my wife. Now the battery is dead and it will cost me 235 dollars to replace. That is 1/3 the cost of over 800 dollars we paid for the entire vacuum. In two to three years Samsung no longer provides parts and was directed to a third party to get the battery. This is a TERRIBLE way to service a product nearing 1000 dollars which is not cheap (we paid 850) at the time. It worked well, but often gets stuck under things and you come home to a chirping fo...

It has a Powerful vac / Strong suction. Suited to / good on hard surfaces and large open areas
Relatively good at navigating / mapping our home
Average on Carpet (but better than some other brands, just dont leave any iPhone cords or loose string items on the floor as they get caught up in the wheel).

I had the Samsung Powerbot 9300 for about 8 weeks and it was working OK. The mapping feature is useless. It doesn't map properly, but the cleaning was pretty good - good suction. After about 8 weeks of use the vacuum cleaner suddenly started doing odd things like stopping after a few minutes on a scheduled clean, missing heaps of areas, unable to navigate the rise between my floorboard areas and carpeted areas (which it had previously done without a problem) and going around in circles then stopping in the middle of the floor and not returni...
