Front loading or top loading washing machine?

Own a front loader (IFB). IN the last 7 or more years it has functioned well. I bought a front loader specifically for water saving as very little water is required to dip, tumble and rotate and soak cloths, as compared to top loaders, where it needs to be at least half filled with water to do the same. I checked by measuring the water drained during a typical wash and it takes about 50 litres for a full cycle of wash and rinse.
 
It makes me wonder whether the duration of the spin cycle chosen by Samsung isn't long enough. Bizarre if that was the case.
Samsung and LG both go to around 14 minutes of spin in last round so it must be something else.

In the other thread you mentioned "MirAIe enabled appliances" about Panasonic. Panasonic is a Japanese brand and wouldn't use a Russian term "Mir" in their marketing. The Mirai meaning in Japanese is "future". Probably they think AI future is the in thing now. Some smart ass in advertising or management did the AI caps in Mirai to make it look like two different words.

Yeah, my guess is unbalanced spin

The Panasonic MirAI thing is India only from what I can tell with even the software being developed here.
 
My brother's family has got a Samsung AI abroad. They thought AI would save them time and effort. In reality, it takes them more time to do things via mobile app. If they are not at home then they have to keep an eye on the running status, as the machine gives them very less time to make another selection before it shuts down after completing the wash. They often need to run another spin cycle as the 1400 one doesn't do a satisfactory job. I think the app should be able to line up two spin cycles back to back. And then you can't power on the machine remotely. I hope the current breed of AI machines don't have these shortcomings. If my machine has Wi-Fi then I should be able to power it on remotely.

I bought the base model of 8kg LG on your recommendation few years back. AI option on appliances back then was gimmicky. My base model LG is quite quick to resume operation if it's interrupted for some reason. AI machines would take their own sweet time to recheck everything. I read such comments in the reviews and I didn't look into AI models further for this reason alone. I think AI models have become more refined lately.

Because of DirectDrive, LG is very quiet. A couple of times my family members told me that I forgot to start the machine after putting in the clothes. For certain cycles, you can't hear much even if you are standing right in front of it!
Not sure which model your brother's family is using but in the SmartThings app, Stay Connect provides full control of the machine if you also enable Smart Control on the machine. It then doesn't turn off the machine and allows you to run any other cycle.

You can also customize each mode to specify the number of cycles, save it and use that mode instead. Also SmartThings supports location and time based cycles, so you can plan the cycle accordingly if you don't want the washed clothes lying in the machine for too long.

I use the machine at 1000 rpm which is also what the technician suggested and I am pretty happy with it in terms of dryness in Mumbai winter conditions.
