Are Washing Machine Spin Speeds A Con?

Washing manufacturers wont tell us what the optimum spin speed is because they charge extra for spin speed and the faster they spin the more they can charge. What are your thoughts and experiences on the best spin speed for a washing machine?

My argument is basically this, there must be one, optimum spin speed, that balances drying efficiency with the wear and tear effects on the clothes and the washing machine itself. Washing machines should spin at that speed, and they all did about 15 years ago (1100 or 1200). Then someone increased their spin speed by 100 revs, (which I can’t believe makes that much difference) and said buy our washing machine, it spins faster than everyone else’s. Then someone else brought one out that spun another extra 100 revs a minute and so on, until we now have at least 7 different spin speeds to choose from.
It wouldn’t be so bad if the fast spinning washing machines had bigger motors and better suspension. When buying a car with a faster, more powerful engine, you pay more, but get a physically bigger and more powerful engine. But with washing machines you tend to get exactly the same size and build-quality motor, which has to work harder, and the suspension (which also works harder) is usually exactly the same too.
Many washing machines today spin far too fast for the build quality of the washing machine, and are likely to be noisy, bounce around and suffer wear and tear consequences.

I don't see why spinners seem to be out of favour these days. They're fast, cheap (esp second hand), reliable (in my experience), save on tumble-drying bills if you can't hang outside and are convenient for hand washes.
Granted you need to transfer the wash and some people may not have room.

Your method sounds a bit mad, but it is a great idea apart from than the hassle involved, and the space needed to store the spinner, so it’s not for most people. However, it saves the most strenuous job for a separate machine that can cope with spinning much faster than a front loading washing machine is ever likely to be capable of.
I did once visit a customer, who like you, always set her front loading washing machine to either not spin, or spin at the slowest speed, and then spun them out in a separate spinner. Her washing machine was in a remarkably clean and good condition.

Hi... just a quick remark on the Hoover Nextra... mine has a max speed 1400 but I usually set the highest speed at 1000. Provided that one chooses a cotton programme it will carry out a final spin sequence for a duration of over 10 minutes. The first minute foresees a slower spin speed regardless of your settings with an increment of the latter after every minute: by the third minute it would have reached 1000 rpm and continue with that speed for the remaining time unless one's chosen a higher speed. I agree with Steve about the spin only programme which is ridiculously short and low in speed... the only way out of it is to repeat it several times should you get stuck with an out of balance load. All in all, I am satisfied with the Nextra... I had it for almost 2 years and it has only in a very few occasions detected an unbalanced load and consequently it has reduced the spin speed to 600/800... it has never drastically cancelled the spin sequence. I'm off... thank you for this great site!!

My own first automatic was a Servis Easiwash 600, back in 1992. I would spin for 5 minutes at just 600rpm, and though not great, you couldn't physically ring out any more water from heavy items such as jeans and towels.
For a number of years, I ran a hotel laundry. We had two Primus 10KG automatic machines, with a max spin speed of 400rpm. Towels would be put in a 5kg hydro-extractor once taken from the machine, and spun for 5 mins at 1450rpm. This seemed to be the most efficient amount of time. The amount of water extracted from the load over 5 mins, was negligible, being just a trickle out of the waste pipe at most.
My washing machine (an AEG 76669) has top spin speed of 1600rpm. The cottons spin dry lasts 9 minutes or so, with the last 5 mins or so at the top selected speed. I have a video of my machine spinning (I hope I'm not breaking any rules, they are my own video's)-
http://www.youtube.com/watch?v=kQvX0J1ERpo (spin at 1600rpm)
http://www.youtube.com/watch?v=eSVyRpZh4z0&NR (spin at 1200rpm)
I only ever spin at 1200rpm as this seems to remove enough water . I have noticed the fuller the load, the dryer the clothes seem to feel after the spin, possibly because of the drum being well balanced? In summer months, when I'm able to peg clothes on the line, I tend to spin at just 900rpm (my machine has variable spins of 400rpm; 700rpm; 900rpm; 1200rpm; 1600rpm), which saves on ironing.

Regarding spin speeds it seems that the actual maximum spin speed is only available on a few programs, other programs use an optimum spin speed that you can only reduce. So for the majority of washing needs a spin speed above 1200 is rarely used. Compare the spinning specs of Miele W3240 (1400 rpm) and Miele W364WPS (1600 rpm) there are only three programs that spin faster than 1400 (cottons, express and spin/drain) all others are using 1200 or less.
You may want to pay more for other extras on a particular model and the faster spin speed comes as a bonus but I don’t think it is the headline catcher the manufacturers would have us believe.

(BTW, the bosch has lasted years. It has been through 2 sets of bushes and a main drum bearing but is still going even though we've had 2 kids so it has probably done a wash every day for 9 years! We're having an extension built and the old girl has a dead spot in the motor and there is signs of slight play to the main bearing so I'm thinking of retiring her at last but she has served me well and I've found her easy to fix especially with the Bosch web site to get parts online and diagrams).

To take an extreme as an example, if a washing machine only spun at 400 rpm it would be exceptionally smooth and quiet, it would be a lot cheaper and it would almost certainly last much longer. Clearly 400 is so slow it would be useless so the spin needs increasing to something that extracts the maximum amount of water from laundry before price, noise, longevity and additional wear and tear start to cancel out the advantages of getting a bit more water out.
In any design whether it's a car or a house there's always an optimum size. You can always show that bigger or faster does something better or quicker but finding the optimum is about balancing results with efficiency and cost. Washing machine manufacturers don't want to show us that optimum spin speed because it would wipe out lots of models in their range. My best guess is that an optimum spin speed for a washing machine is between 1200 - 1400.
Unfortunately, a further complication is that the higher the build quality of the washing machine the less the negative impact of spinning faster (other than the purchasing cost) is. Therefore a Miele washing machine spinning at 1600 is going to be more stable, quieter, last longer etc. than a cheap washing machine spinning at 1200. Isn't it always the case that everything is so complex and there's rarely a definitive answer?
The only thing I can advise is not to be obsessed or over impressed by spin speeds on washing machines. That many cheap washing machines spin way too fast for their build capabilities and that if you want a really fast spin try to buy a better quality brand that can cope with it.
My current washing machine spins at a maximum 1400 (a Miele W 3740) and it is perfectly fast enough.
