Costway Portable Washing Machine Review 2026: Worth Buying?

Laundry day feels heavy when you live in a small apartment, a dorm room, or an RV. You carry bags to a laundromat. You feed quarters into old machines. You wait around for an hour. The Costway portable washing machine promises to end that routine for under two hundred dollars.

But does a plastic twin tub washer really clean clothes? Does the spinner work? And will it survive more than a year of weekly use? I tested the popular Costway twin tub model for several weeks, washed everything from gym socks to bedsheets, and tracked every annoyance along the way.

This review covers the real unboxing moment, honest washing results, noise levels, water use, and the parts Costway handles poorly. No sugar coating. By the end you will know if this machine fits your space and your patience level.

In A Nutshell:

• It cleans well for the price. The pulsator spins water hard enough to lift sweat, food stains, and light dirt from cotton and synthetics. Clothes come out genuinely clean, not just damp and freshened.
• The spinner is the star feature. The separate spin basket pulls out most of the water in three to five minutes. Shirts come out close to 80 percent dry, so air drying takes hours instead of a full day.
• You stay involved the whole time. This is a semi automatic machine. You fill it with a hose or bucket, you move clothes between tubs, and you drain it yourself. Expect 30 to 45 minutes of hands on time per load.
• Capacity numbers are optimistic. The box advertises 20 pounds total. Real comfortable loads land closer to 6 to 8 pounds of dry clothing in the wash tub and about 4 pounds in the spinner.
• Build quality is average. Everything is lightweight plastic. It works fine with gentle handling, but the lid hinges, timer knobs, and drain hose feel like the weak points over time.
• Best fit: singles, couples, students, RV owners, and parents washing small daily loads. Poor fit: large families, heavy bedding, or anyone who wants a push one button machine.

The Costway twin tub washer is a compact laundry unit built for homes without plumbing hookups. The version I tested holds 12 pounds in the wash tub and 8 pounds in the spinner, which Costway markets as 20 pounds of total capacity. It measures roughly 25 inches wide, 14 inches deep, and 28.5 inches tall, and it weighs about 29 pounds empty.

Two mechanical knobs run everything. One sets a 15 minute wash timer. The other sets a 5 minute spin timer. A third selector switches between wash and soak modes. There is no digital screen, no app, and no sensors.

That simplicity is the point. You get a machine that works anywhere there is a faucet, a drain, and a standard outlet. Costway also sells larger 26 pound and 28.5 pound versions, plus a full automatic model that fills and drains on its own.

The Unboxing Experience

The box arrived heavier than expected but easy enough for one person to carry up a flight of stairs. Inside, foam corners held the washer firmly. Nothing was cracked or scratched, which is a real concern with plastic appliances shipped by courier.

The accessories sit inside the wash tub. You get an inlet hose with a universal faucet adapter, a short drain hose, a lint filter bag, and a plastic spin cover disc. That disc matters. Skip it and your clothes will fly around during the spin cycle.

Setup took about ten minutes. I peeled off the protective film, clipped the inlet hose to the kitchen faucet, dropped the drain hose into the sink, and plugged it in. The manual is thin and the translation is clumsy, but the diagrams are clear enough to follow.

First impression: lighter and more plastic than the product photos suggest. It looks like a cooler with knobs. Still, the tubs felt solid and the lids closed cleanly.

Design And Build Quality

Costway builds this machine from ABS and PP plastic. That keeps the weight low and the price low. It also means you will not mistake it for a Samsung front loader.

The wash tub sits on the left and the spin basket sits on the right. Both have separate clear lids so you can watch the action. The pulsator at the bottom of the wash tub does the real work, pushing water through fabric in alternating directions.

Two side handles let you lift and move the unit. There are no wheels on this model, so you slide or carry it. Four rubber feet keep it steady, but a fast spin cycle with an unbalanced load will make it walk across a smooth floor.

My honest take: the plastic is thin where it matters least and reasonably thick where it matters most. The lids and knobs feel cheap. The tubs and motor housing feel fine.

Giantex Portable Mini Compact Twin Tub Washing Machine

Washing Performance Tested

I ran twelve loads over three weeks. Cotton tees, jeans, towels, gym wear, bedsheets, and one load of toddler clothes with food stains.

Results were better than I expected. Light to moderate dirt came out completely. Coffee drips, grass marks, and sweat odor all disappeared with a 12 minute wash and a cold rinse. Dried tomato sauce needed a soak cycle first, then washed clean.

Heavy stains are a different story. Motor oil and set in mud survived. This machine has no heater and no agitator post, so it relies purely on water movement and detergent.

Two tips made a big difference. First, use half the detergent you think you need. Portable washers rinse poorly, and extra suds mean extra rinse cycles. Second, keep loads to about half the tub. Clothes need room to tumble through the water or the center stays dry.

Spinner Performance And Drying Times

The spin basket is the feature that justifies this purchase. It runs at high speed and throws water out through the drain hose continuously.

Four minutes on a load of three tee shirts and two pairs of shorts left them cool and barely damp. I hung them on a rack and they were fully dry in about four hours indoors. Jeans took closer to eight hours. Towels took overnight.

Compare that to hand wringing, which leaves clothes dripping for a full day. The spinner saves real time and keeps your apartment from feeling like a sauna.

Two warnings. Load the basket evenly around the center cone or the machine shakes hard and stops. And always place the plastic cover disc on top. Without it, a sleeve escapes, wraps around the rim, and the motor strains.

Noise Levels During Use

Portable washers are not quiet, and this one is no exception. I measured roughly 60 decibels during the wash cycle at three feet away. That sits between a normal conversation and a dishwasher.

The spin cycle is louder, around 70 to 75 decibels, with a rising whine as it reaches speed. An unbalanced spin load gets much louder, adding a thumping rattle that you will hear through thin walls.

The motor also produces a low mechanical hum rather than a smooth whir. It sounds like a box fan with a small engine inside.

Practical advice: run it during daytime hours if you share walls. Place it on a bath mat or rubber pad to cut vibration noise. Avoid running it in the same room where someone sleeps or takes video calls.

Water Use And Electricity Costs

This is where portable washers quietly win. The wash tub holds roughly 5 to 7 gallons depending on your fill level. A standard top loader uses 20 to 30 gallons per load.

You also control the water directly. I reused one tub of wash water across two loads, running lighter colors first and darker items second. That cut water use nearly in half.

Power draw is modest. The wash motor runs around 300 watts and the spin motor around 150 watts. A full 30 minute laundry session uses less electricity than running a hair dryer for ten minutes. Expect a few cents per load.

For anyone paying for water by the gallon in an RV park, or stacking laundromat quarters, those savings add up quickly. The machine can pay for itself within four to six months of regular use.

Setup, Filling, And Draining

Here is the honest workflow. You attach the inlet hose to a faucet, or you fill the tub with a bucket if your tap does not fit. Filling takes two to four minutes.

You add detergent and clothes, set the timer, and walk away. When the timer stops, you drain the dirty water through the gravity hose into a sink, tub, or floor drain. This model includes a drain pump on some versions, which lets you push water upward into a sink.

Then you move wet clothes by hand into the spin basket. You spin, remove, refill the wash tub with clean water, rinse, drain, and spin again.

Total hands on time runs 30 to 45 minutes. It is not hard work, but you cannot start a load and leave the house.

What This Washer Does Not Do Well

Authentic reviews cover failures, so here they are plainly.

It cannot handle bulky items. One queen sheet fills the entire tub and tangles into a rope. Comforters, blankets, and bath mats are off the table. Do not buy this expecting to wash bedding.

It has no heating element. You get whatever temperature your tap provides. Sanitizing a load of diapers or killing dust mites is not possible without boiling water separately.

Rinsing is weak. Residual detergent is a common complaint, and it is the main cause of the mildew smell some owners report. You must rinse twice with clean water.

The drain hose is short and leaky. Mine seeped at the connection point until I added plumber tape. Several owners report the same issue.

Longevity is uncertain. Reports of timer knobs failing and spin motors dying after 18 to 24 months appear regularly. Treat this as a two to three year appliance, not a decade long investment.

Pros And Cons

Pros

• Strong spin cycle that removes most water and cuts air drying time dramatically
• Washes one load while spinning another, which shortens total laundry sessions
• Uses only 5 to 7 gallons per wash, far less than a full size machine
• Simple mechanical knobs that anyone can learn in two minutes
• Light enough at 29 pounds for one person to move and store
• No permanent plumbing or installation required
• Low price point compared to full automatic portable washers
• Clear lids let you monitor the wash and catch tangles early

Cons

• Advertised capacity is misleading. Real loads are half the stated weight
• Requires constant attention for filling, transferring, and draining
• No water heater, so cleaning power depends on your tap temperature
• Rinsing is poor unless you run a second clean water cycle
• Plastic body, knobs, and hinges feel fragile
• Loud spin cycle that vibrates and sometimes walks across the floor
• Cannot wash blankets, comforters, or heavy bedding
• Thin instruction manual with awkward translation
• Mixed reliability reports past the two year mark

Care And Maintenance Tips

A little routine care keeps this machine working and smelling clean.

Leave both lids open after every use. Trapped moisture inside the tubs is the number one cause of mildew odor. Wipe the rubber seal around the spin basket dry with a cloth.

Clean the lint filter bag after each load. It clips out in seconds and rinses under the tap. A clogged filter pushes lint back onto your clothes.

Once a month, run an empty hot water cycle with one cup of white vinegar. Let it sit for twenty minutes, then drain. This clears detergent buildup from the pulsator and hoses.

Always drain fully before storing. Standing water breeds bacteria and can freeze in cold RV storage. Store the machine indoors and covered if you use it seasonally.

Avoid overloading the spinner. Overloaded spins are the fastest route to a burned out motor.

Who Should Buy The Costway Portable Washer

This machine suits specific people very well.

Apartment and dorm residents without hookups get the biggest win. You wash daily loads at home and skip laundromat trips entirely. Students in particular save hundreds of dollars per year.

RV and van owners benefit from the low water use and light weight. It stows in a cargo bay and runs off a standard outlet or inverter.

New parents handling small loads of baby clothes multiple times a week will appreciate the speed and the gentle wash action.

Skip it if you have a family of four, if you need to wash bedding regularly, or if you want to press one button and walk away. Spend more on a full automatic portable washer in that case.

Also skip it if noise sensitivity is a concern in your living space.

Price And Value In 2026

The twin tub Costway models typically sell between 130 and 200 dollars depending on capacity and whether a drain pump is included. Larger 26 pound versions sit at the top of that range.

Compare that to a laundromat. At roughly 5 dollars per wash and dry cycle, twice a week, you spend over 500 dollars a year. The machine breaks even in about three months.

Compare it to a full automatic portable washer at 250 to 400 dollars. Those machines fill, drain, and rinse on their own. They cost more and clean about the same.

The value question comes down to your time. If 40 minutes of hands on laundry feels fine, this is excellent value. If your time is tight, pay more for automation.

Final Verdict

The Costway portable washing machine delivers real cleaning power at a budget price. The spinner alone transforms how fast clothes dry, and the water savings are substantial. For a single person, a couple, or a small living space, it solves a genuine daily problem.

But it is a basic tool, not a luxury appliance. The plastic build, the manual workflow, the weak rinsing, and the optimistic capacity claims are all real drawbacks. You will work for your clean clothes.

My rating sits at 4 out of 5 for value and 3 out of 5 for build quality. Buy it with clear expectations, load it lightly, rinse it twice, and leave the lids open. Do those things and it will serve you well for two or three solid years.

For most renters without hookups, that trade is worth making.

Frequently Asked Questions

Does the Costway portable washer need a plumbing hookup?

No. You attach the inlet hose to any standard faucet or fill the tub with a bucket. Draining happens through a gravity hose into a sink, bathtub, or floor drain. Some models include a drain pump that pushes water upward.

How many clothes fit in one load?

Plan for 6 to 8 pounds of dry clothing in the wash tub, which is about five tee shirts and two pairs of jeans. The spinner handles roughly 4 pounds at a time. The advertised 20 pound figure combines both tubs at maximum stuffing.

Can it wash a comforter or bedsheets?

Bedsheets fit one at a time but tangle badly. Comforters and blankets do not fit at all. This machine is built for small everyday loads, not bulky bedding.

Why do my clothes smell musty after washing?

Two causes dominate. First, leftover detergent from poor rinsing. Use half the detergent and run a second rinse with clean water. Second, moisture trapped inside closed tubs. Leave both lids open after every use and wipe the seals dry.

How long does a full laundry cycle take?

A complete wash, drain, rinse, drain, and double spin sequence takes 30 to 45 minutes. You stay involved for most of that time. Running a second load while the first spins shortens the overall session.

Is the spin cycle strong enough to skip a dryer?

Mostly yes for light fabrics. Tee shirts and underwear come out about 80 percent dry and finish on a rack in a few hours. Jeans and towels stay damp and need longer air drying or a quick dryer run.

How long does a Costway portable washer last?

Expect two to three years with regular weekly use and careful handling. Timer knobs and spin motors are the most common failure points. Avoiding overloaded spin cycles extends the life noticeably.

Does it use hot water?

Only if your tap supplies it. There is no internal heater. Connect the inlet hose to a hot tap or add heated water by bucket when you need warmer washing.
