Spin speed—measured in revolutions per minute (RPM)—is key to achieving cleaner, drier clothes. Higher spin speeds mean more effective water extraction, allowing your items to spend less time in the dryer or on the line.
It really depends on what you're washing. Unless You're dealing with delicate items, I always use the highest spin option, as it makes drying faster and cheaper. Especially on a front-load machine, it shouldn't effect the clothes at all.
Generally speaking, cold wash cycles are best for delicates, colored, and normally soiled clothing; warm water is best for more soiled clothing and whites; and hot water is best for very soiled clothing or for loads, like underwear and towels, where you want to remove germs and allergens.
Would go for a minimum 1200 but 1400 would be better really. It's particularly useful if you don't have much room for drying clothes or have a damp/cold hous as if you get a slow spin machine, it leaves more water in the clothes and takes ages to dry.

A 1200RPM - 1400RPM spin speed will suit most family situations, balancing economy and performance. Faster spin speeds will decrease the time it takes to dry your clothes. Faster spin speeds reduces the time required in a tumble dryer.
The Heavy-duty cycle is for jeans and towels, or heavily soiled clothing. This cycle uses a long wash cycle combined with high-speed agitation and spin. The Bulky cycle is great for pillows, blankets, and rugs. This cycle allows items to soak in water and soap for a short time before starting the wash.
While both front-load and top-load washers are effective for cleaning, front-loaders are better at removing dirt and stains, thanks to the horizontal drum rotation and tumbling motion. The design of a front-load washer repeatedly lifts and drops your laundry, using gravity to knock clothes against each other.
Washers generally have a default spin speed that varies based on the type of fabric. For example, wool, lingeries or blouses require a slower spin speed (around 600-800 RPM), synthetic fabrics need around 800-1000 RPM, while a high-speed (900-1400 RPM) is recommended for cotton.
As a rule, lower spin settings are perfect for delicate fabrics and prevent parts of garments such as sleeves getting tangled. A fast spin speed is perfect for towels or heavy fabrics like denim. The spin is measured in 'revolutions per min' or RPM.
Clothes are much more likely to shrink when exposed to hot water or high dryer settings. Washing clothes in cold water goes a long way toward preserving the “off-the-rack” size. Avoiding heavy duty cycles, fast spins and high-heat drying can also prevent shrinkage.
Washing Machine Cycle - Your luxury towels can be washed on the regular or normal cycle in your washing machine. These cycles work best for cleaning towels, as the faster spin and longer washing time versus the gentler cycles helps to better clean dirt and bacteria from the fabric fibers of the towels.
Washing: Jeans and jeans go hand in hand
 The machine should not be too full to avoid severe wrinkles - a moderate spin speed of 800 or 1000 revolutions is also helpful for this. Washing several pieces of jeans together prevents them from staining other textiles.
A second rinse bath produces a much cleaner final product by rinsing off the soil that is redeposited during the first rinse. Often times, the second rinse tank includes a heated facility water inlet which constantly overflows the second rinse tank with small amounts of water to ensure water cleanliness.
Heavy Duty
 The Heavy Duty washing machine cycle uses hot water and high spin speed for thick, heavily-soiled fabrics, like towels and jeans. Loads washed in this cycle may take longer because these items tend to absorb more water than other types of fabrics.
For lightly soiled items, a low or light setting works well without overworking the fabric. Medium soil levels suit most everyday laundry needs. Meanwhile, heavily soiled clothes benefit from a high setting for deep cleaning.
The heavy-duty or stain removal cycle works best for tough stains. If your washer has a pre-wash or steam function, use it for added cleaning power. Hot water settings are ideal for greasy stains, while cold water helps with protein-based stains. For delicate fabrics, stick to a gentle cycle to avoid damage.
Warm washes (40°C) are best for items that have come into contact with body fluids, such as underwear. Wash such garments on warm temperatures with Ariel. Cold washes (15-30°C) should be used for lightly- to moderately-soiled daily items.
Step 5: Choose the Proper Setting
 For most laundry loads, the normal wash cycle is best. But if you haven't experimented with cold-water washing, give it a shot. Many detergents have been reformulated to work better at lower temperatures, so we think you'll be happy with the results.
The rinse and spin cycle in washing machines is essential for effective cleaning. During this cycle, water rinses clothes to eliminate detergent residue, while the spin function removes excess water, making drying faster.
While a high spin speed is idea for more robust fabrics, such as denim, cotton, and wool, using a high speed on delicate fabrics, such as silk, can lead to damage. Equally, using a high spin speed can increase how creased your garments are after a wash.
However, most washing machines are set to the standard 1200 rpm/1400 rpm, a speed which suits most washing loads. So you don't have to worry about the spin cycle speed for the majority of the time. However, you may want to change the speeds when washing delicate items or silk fabrics.
Through the research that we've done - we've found the difference between a 1200rpm and a 1600rpm machine is that the 1600rpm extracts about double the amount of water. Between 1600rpm and 1400rpm, there's about a 50% increase in the amount of water released.
