String Mop or Cotton Mop: Which Is Right for Your Floor?

For wet floors or floors with lots of spills, choose a cotton mop because it absorbs more. For everyday use where you want a more eco-friendly option, choose a string mop made from waste yarn. So the choice between a string mop and a cotton mop depends on how much water needs to be absorbed and how much an eco-friendly material matters to you.

In this article, a “string mop” means a mop head made from waste yarn that is processed by machine into mop strings and still contains some cotton, while a “cotton mop” means a mop head made from 100% cotton, like clothing fabric.

Where do cotton and string mops come from?

Cotton comes from the cotton plant (genus Gossypium), a shrub whose seeds are wrapped in fine fibers. These fibers are mostly cellulose, spun into thread and woven into cotton fabric, the same material used in much clothing.

String mops come from waste. At Nagoya, the material is waste yarn that we manage ourselves and that still contains some cotton. This waste yarn is processed by machine into mop strings. That way, material that would have been thrown away gets a new use.

How string mops and cotton mops work

String mop

The strands absorb water and liquid dirt, then spread it as you push the mop. Because the strands are loose, the mop head can get into the gaps around table legs and wall corners. The material comes from waste processed by machine, so this option is more eco-friendly.

Cotton mop

The mop head is made from 100% cotton, like clothing fabric. It absorbs more than a string mop, so it suits floors with lots of water or spills.

Comparison table

Aspect	String mop	Cotton mop
Head material	Waste yarn processed by machine into mop strings, still contains some cotton	100% cotton
Water absorption	Adequate, lower than cotton	Higher
Eco-friendly	More eco-friendly because it uses waste yarn	New cotton material
Reach into gaps and corners	Good, loose strands	Depends on the head shape
Color	Bright white	More yellow
Drying speed	Slower to dry	Faster to dry
Odor risk	Appears if stored damp, so dry until completely dry	Appears if stored damp

Absorption and wringing

A cotton mop absorbs more water, which helps a lot when the floor has many spills or has just been washed. Because it holds a lot of water, wring it out until it stops dripping before using it on a wood or laminate floor.

A string mop absorbs less than cotton, but enough for daily mopping. Its downside is that it takes longer to dry than a cotton mop, so dry it completely before storing it. This option suits you if you want to use a more eco-friendly material.

Why string mops are more eco-friendly

String mops are made from waste yarn processed by machine, so that waste gets a new use and is not thrown away right away. If your priority is reducing waste, a string mop is the better choice compared with a mop made from new material.

Which is right for your floor

Based on your needs

Wet floors, lots of spills, or business areas: a cotton mop, because it absorbs more water.

Daily mopping at home when you want to be eco-friendly: a string mop.

Large areas such as lobbies or business spaces: a lobby mop 60-90 cm wide, available in cotton and string versions.

Based on floor type

Ceramic and granite: both work. A string mop gets into deep grout lines and gaps more easily.

Wood, parquet, and laminate: choose either, but wring it out very dry. A cotton mop holds more water, so it needs to be wrung out more carefully. Avoid excess water at the joints between boards.

“Pel” is a complete mop with a handle, while “refill” is the replacement head. See all options in the Nagoya mop category.

What to look for before you buy

• Handle: choose at least iron (metal). A thin plastic handle bends easily when a wet mop is pressed to the floor. Stainless steel and iron handles, like those on Nagoya products, hold up better under pressure.
• Head joint: a threaded joint makes the mop head easy to remove for washing.
• Replaceable head: the mop head is the part that wears out fastest, while the handle can be used for a long time.
• Head material: choose cotton if you need high absorption, or a string mop if you want a more eco-friendly option.

How to care for a mop so it does not smell

A musty smell on a mop appears because the mop head is stored damp for a long time. These steps apply to both string mops and cotton mops:

• Rinse the mop head with clean water right after use, and do not leave it soaking in the bucket.
• Wash with soap or detergent, then rinse until there are no suds.
• Wring it out until it stops dripping.
• Dry the mop head in a sunny, breezy place, with the head facing down so water drains out. A string mop needs longer drying time than a cotton mop.
• Store it only after the mop head is completely dry, not while it is still damp.
• Clean the bucket and storage area regularly, because a dirty bucket can make a clean mop smell again.
• Replace the mop head if it has thinned, grown mold, or still smells after washing.

A mop head that is often in the sun needs a handle and joint that last. Nagoya was founded in 2002 and takes care of the quality of its products, including metal parts such as the handles used for string mops.

Quick summary

• A cotton mop (100% cotton) absorbs more water, good for wet floors and lots of spills.
• A string mop is made from waste yarn processed by machine, more eco-friendly and enough for daily mopping.
• On wood or laminate floors, wring the mop out very dry, especially a cotton mop.
• A string mop takes longer to dry than a cotton mop, so dry it longer before storing.
• Prevent odor by rinsing after use, wringing out, drying, and storing only when completely dry.
• Choose at least an iron (metal) handle and a replaceable mop head.
