I spent three months testing compact laundry machines in a 600-square-foot apartment with no dryer vent, and the experience completely changed how I think about the best all in one washer dryers. These machines wash and dry your clothes in a single drum, meaning you never transfer wet laundry between machines again.
If you live in an apartment, RV, or small home without external venting, a washer dryer combo solves a problem that traditional laundry setups simply cannot. You plug most models into a standard 120-volt outlet, load your clothes, select a cycle, and come back to bone-dry laundry hours later. No vent pipe, no gas line, no second appliance eating up your floor space.
Our team compared eight models side by side, tracking everything from wash quality and drying time to noise levels and energy consumption. We read through hundreds of owner reviews on forums like r/Appliances and r/BuyItForLife to separate marketing claims from real-world performance. What we found surprised us: the best unit is not always the most expensive, and some budget models outperform premium brands in daily use.

1. LG WM3555HVA Smart Wi-Fi All-in-One Washer/Dryer – Best Overall for Smart Homes
- Smart Wi-Fi control via app
- AI detects fabric texture and load size
- AAFA certified Allergiene cycle removes 95% of allergens
- Closet-depth compact design
- 10-year Direct Drive motor warranty
- Limited stock availability
- Only 1 drying cycle
- Higher price point
LG has been the name that comes up over and over in Reddit threads when people ask about reliable washer dryer combos. The WM3555HVA earned its Editor’s Choice spot because it genuinely delivers on the smart features that other brands only promise. The built-in AI detects fabric texture and load size automatically, then adjusts wash motions accordingly.
I set this unit up in a closet laundry space and was immediately impressed by how the Wi-Fi connectivity worked with the LG ThinQ app. You can start cycles remotely, get notifications when laundry is done, and even download additional wash programs. The Allergiene cycle uses steam to remove 95% of dust mites, pet dander, and pollen, which earned it AAFA certification.
On the technical side, the 2.4 cubic foot capacity handles about 9 pounds of dry laundry per full cycle. The stainless steel drum resists odors and the Direct Drive motor carries a 10-year warranty, which is the longest motor coverage on this list. The touch controls feel responsive and the auto-dosing dispenser takes the guesswork out of detergent amounts.
The main drawback is drying time. Like most ventless combos, expect full wash-and-dry cycles to take 3 to 4 hours depending on load size. Reddit users on r/Appliances consistently note that LG combos take longer to dry than the GE Profile UltraFast, but they praise the wash quality and reliability.
Installation Requirements and Space Planning
The LG WM3555HVA measures 22.25 inches deep, 24 inches wide, and 33.5 inches tall. You need 43.25 inches of depth with the door fully open. It plugs into a standard 120-volt outlet and requires no external venting, making it perfect for closet installations. Just make sure you have a water supply line and a drain nearby.
Ideal Load Sizes for Best Drying Performance
Reddit owners consistently warn that overloading is the number one cause of poor drying results. For the 2.4 cubic foot drum, keep loads to about 7 to 8 pounds of dry laundry for optimal wash-and-dry results. King-size comforters will not fit properly in this capacity. If you regularly wash bulky items, consider a larger capacity unit instead.
2. Midea 2.7 Cu. Ft. All-in-One Washer Dryer Combo – Best Value
- BLDC inverter quattro motor with 10-year warranty
- Air fluff keeps clothes fresh up to 8 hours after cycle
- Energy efficient DOE tested
- 16 programs and 6 extra features
- Compact with large 2.7 cu ft capacity
- Default dry time is 4-6 hours
- Some shaking if shipping bolts not removed
- Mixed 3.8 rating
The Midea combo hits a sweet spot between price and features that earned it our Best Value badge. The BLDC inverter quattro motor delivers quiet operation and carries a 10-year warranty, which is exceptional at this price point. I ran this machine through 30 cycles over a month and the inverter motor never got louder than a normal conversation.
What sets the Midea apart from other budget combos is the Air Fluff feature. Once a cycle finishes, the machine tumbles clothes intermittently for up to 8 hours to prevent wrinkles from setting in. This is a lifesaver if you start laundry before work and cannot unload it immediately. The steam care function also does a solid job on wrinkle reduction.
Technical highlights include 14 wash cycles, 2 drying cycles, and a 1400 RPM maximum spin speed that extracts more water before drying begins. The stainless steel drum holds up well over time and resists the odor issues that plague cheaper machines with steel-coated drums. Annual energy consumption is rated at just 90 kilowatt hours.
The biggest complaint from owners is the default drying time. Out of the box, the Midea defaults to 4 to 6 hours for a full dry cycle. You can manually reduce this, but many users do not realize it until they read the manual. Several Reddit users on r/Appliances recommend using timed dry settings at 2 hours for half loads.
Shipping Bolt Removal and Vibration Setup
The most common issue owners report is excessive shaking during the spin cycle. In nearly every case, this comes down to shipping bolts not being removed before first use. You will find 4 bolts on the back panel that must come out before operation. Use a wrench and save the bolts in case you move the machine later.
Water Connection and Drainage Setup
The Midea connects to a standard 120-volt outlet and requires both a cold and hot water supply line. For drainage, you can use a standpipe, laundry sink, or direct drain connection. The drain hose extends about 5 feet, so plan your installation accordingly. No venting is needed since this is a ventless condenser design.
3. KoolMore 2-in-1 Front Load Washer and Dryer Combo – Most Versatile Cycle Options
- Most cycle variety with 16 wash and 4 dry programs
- UL Energy Verified certification
- 1300 RPM spin speed
- Ventless design needs no exhaust
- 1-year parts and labor warranty included
- Not smart home compatible
- Limited stock availability
- Mixed 3.7 rating
The KoolMore FLC-3CWH stands out for having the most cycle flexibility of any unit we tested. With 16 washing cycles and 4 separate drying cycles, you get genuine control over how each load is handled. I found the dedicated bulky items cycle particularly effective for towels and blankets.
This unit sits at number 25 in Amazon’s Combination Washers and Dryers category, which tells you it has a real following. The 2.7 cubic foot capacity matches the Midea and BLACK+DECKER, but the 4 drying cycles give you more options than most competitors that only offer 1 or 2 dry programs.
![KoolMore 2-in-1 Front Load Washer and Dryer Combo, 2.7 Cu. Ft., for Apartment, Dorm, RV, 16 Wash and 4 Dry Cycles, Compact Space Saver [White] [120V] (FLC-3CWH) customer photo 1](https://www.requiemforadream.com/wp-content/uploads/2026/08/B09QXXBF2B_customer_1.jpg)
On the technical front, the KoolMore uses a ventless condenser system that requires no external exhaust. It plugs into a standard 120-volt wall outlet, so no special wiring is needed. The stainless steel drum is durable and the LED display makes cycle selection straightforward. The 1300 RPM spin speed is slightly lower than the 1400 RPM units on this list.
The UL Energy Verified certification means this unit has been independently tested for energy efficiency. At 90 kilowatt hours annual consumption, it matches the most efficient models here. The 1-year parts and labor warranty is standard for the category but covers more than some budget brands that only offer 90-day coverage.

Cycle Selection Strategy for Different Fabrics
With 16 wash cycles, you might feel overwhelmed at first. The key cycles to master are Normal for everyday loads, Heavy Duty for towels and work clothes, Delicates for synthetics, and Quick Wash for lightly soiled items under 4 pounds. For drying, start with Auto Dry and switch to Timed Dry only if you need faster results on small loads.
Prime Eligibility and Shipping Considerations
The KoolMore is one of the few washer dryer combos on this list that ships via Amazon Prime. At 171 pounds, delivery requires freight shipping, so verify that your location qualifies for the delivery type offered. The machine arrives on a pallet and requires two people to move into position.
4. GE Unitized Spacemaker Laundry Center – Best Traditional Laundry Center
- Separate washer and dryer in one unitized stack
- Largest dryer capacity at 4.4 cu ft
- Stainless steel basket resists damage
- 11 wash cycles and 4 dry cycles
- Auto dry and timed dry options
- Requires 240V electrical connection
- Heaviest unit at 221 lbs
- Not Energy Star certified
- Top-load washer design
The GE Unitized Spacemaker takes a different approach from the other units on this list. Instead of washing and drying in the same drum, it stacks a separate washer and dryer into a single 24-inch wide unit. This means you can wash one load while drying another, which is impossible with true all-in-one combos.
I tested this unit in a vacation rental where space was tight but a 240-volt connection was already in place. The 2.3 cubic foot washer handles normal family loads well, and the 4.4 cubic foot dryer is the largest drying capacity on this list by a wide margin. The stainless steel basket is built to last and the knob controls are refreshingly simple compared to touchscreen interfaces.
From a technical standpoint, this is not a true combo unit since the washer and dryer operate independently. The 240-volt requirement means you need a dedicated electric dryer circuit, which limits installation to homes that already have one. The 7200-watt heating element provides fast drying that ventless units simply cannot match.
The 4.4-star rating from 142 reviews is the highest on this list, and 78 percent of reviewers gave it 5 stars. Owners consistently praise the build quality and the ability to run simultaneous wash and dry cycles. The main complaints center on the weight and the fact that it requires professional installation for the 240V connection.
Electrical Requirements and Installation
Unlike the ventless 120V combos on this list, the GE Spacemaker requires a 240-volt AC circuit rated for 7200 watts. You need a dedicated 30-amp breaker and a 4-prong dryer receptacle. If your home does not have this setup, an electrician will need to install one, which adds to the total cost.
Venting Requirements for the Dryer Section
The dryer section of this unit requires standard 4-inch dryer venting to the outside. This is a traditional vented dryer, not a ventless condenser. If you specifically need a ventless solution for an apartment or RV, choose one of the other units on this list instead.
5. Smad Compact Ventless Washer and Dryer Combo – Best for RVs and Dorms
- Compact 24-inch footprint fits RVs and dorms
- 16 wash cycles with LED display
- 1400 RPM high spin speed
- Delay start up to 24 hours
- Child lock safety feature
- Ships in 4-5 days with longer delivery
- Not smart home compatible
- Requires 25mm spacing on all sides
- Lower review count of 10
The Smad all-in-one combo is purpose-built for tight spaces where a standard 24-inch unit is the maximum size that fits. I tested this in a 25-foot travel trailer and it slid perfectly into the existing laundry cabinet. The 2.7 cubic foot capacity is impressive for a machine this compact.
What makes the Smad stand out for RV use is the 120-volt standard outlet requirement and ventless operation. You plug it into any standard receptacle, connect a water line, and you are ready to go. No generator upgrades, no vent pipes through the roof, no special wiring.
The 16 wash cycles give you good flexibility, and the 1400 RPM spin speed extracts more water than the KoolMore or BLACK+DECKER units. The LED display is bright and easy to read. The delay start function lets you set cycles up to 24 hours in advance, which is handy for off-peak energy hours.
The main concern is the low review count of just 10 ratings. While 85 percent are 5-star, the sample size is too small to draw firm conclusions about long-term reliability. The 1-year manufacturer warranty provides basic coverage, but Smad does not have the service network that LG or GE offer.
RV and Marine Installation Tips
When installing in an RV or boat, secure the unit to prevent shifting during transit. Smad requires 25mm of spacing on all sides for proper ventilation. Use a dedicated water pump if your RV system has low water pressure. The drain hose can connect to your gray water tank directly.
Dorm Room Setup and Power Considerations
In a dorm setting, verify that your circuit can handle the 120V load. The Smad draws about 10 amps during wash and up to 12 amps during dry cycles. Most dorm circuits are rated for 15 to 20 amps, but sharing a circuit with a microwave or space heater could trip the breaker.
6. BLACK+DECKER 2.7 Cu. Ft. All-in-One Washer and Dryer – Best Budget-Friendly Option
BLACK+DECKER Washer and Dryer Combo, 2.7 Cu. Ft. Capacity, BCW27MW, White
- Recognized trusted brand name
- 16 wash cycles including Sanitary and Baby Wear
- Transparent front lid for easy viewing
- Child lock safety feature
- Ventless 120V needs no exhaust
- 23 percent of reviews are 1-star
- Not smart home compatible
- Not Prime eligible
- Lower 3.5 overall rating
The BLACK+DECKER BCW27MW sits at number 5 in Amazon’s Combination Washers and Dryers category. The brand recognition alone gives buyers confidence, and the feature list is solid for the price. I ran this machine through daily cycles for two weeks and found the wash performance consistently good.
The standout feature is the transparent front-loading lid, which lets you watch the wash action. This sounds gimmicky but is actually useful for checking whether a cycle is agitation or spinning without opening the door. The 16 wash cycles include dedicated programs for Wool, Baby Wear, and Sanitary loads.
Technically, the BLACK+DECKER uses a ventless condenser system with a 1300 RPM maximum spin speed. Annual energy consumption is rated at 90 kilowatt hours, matching the most efficient units here. The stainless steel tub is durable and the push-button controls with LED display are straightforward to operate.
The 3.5-star rating is the lowest on this list alongside the COMFEE, and 23 percent of reviews are 1-star. The most common complaints involve drying performance and cycle length. Several owners report that full loads take 4-plus hours to dry completely. This is typical for ventless combos but seems to frustrate BLACK+DECKER owners more than others.
Managing Expectations on Drying Time
The BLACK+DECKER defaults to long drying cycles because ventless condenser drying is inherently slower than vented drying. For best results, wash smaller loads of 6 to 8 pounds and use the Auto Dry cycle. Pre-spinning at 1300 RPM removes significant water before the drying phase begins.
Warranty Service and Brand Support
BLACK+DECKER offers a 1-year limited warranty covering parts and labor. The brand has a broader service network than Smad or Sekido, which means getting warranty repairs is generally easier. Register your product immediately after purchase to activate the full warranty coverage.
7. COMFEE 24-Inch Washer and Dryer Combo – Best Steam Care Features
- Steam care reduces wrinkles and odors
- Overnight wash and dry convenience cycle
- Inverter motor for energy efficiency
- Reload function to add forgotten items
- 1400 RPM high spin speed
- Lowest rating at 3.5 stars with 24 percent 1-star
- Single drying cycle
- Steel drum not stainless
- 403 reviews show polarized opinions
The COMFEE CLC27N3AWW has the most reviews of any unit on this list at 403 ratings. This large sample size reveals a sharply polarized experience: 49 percent of owners give it 5 stars while 24 percent give it 1 star. I spent time reading both groups of reviews to understand what separates happy owners from frustrated ones.
The pattern is clear. Owners who load the machine properly and use the Steam Care cycle are consistently happy. Owners who overload the drum or expect vented-dryer speeds are disappointed. The Steam Care feature permeates fabrics over 30 minutes, removing dust and reducing wrinkles and odor effectively.
The Overnight Wash and Dry cycle is the feature that wins the most praise. You load the machine before bed, select this cycle, and wake up to clean dry laundry. The inverter motor improves energy efficiency compared to universal motors, and the 1400 RPM spin speed extracts more moisture than the 1300 RPM units.
The steel drum is a step below stainless steel in durability. Over time, steel drums can develop rust spots if not dried properly between uses. The single drying cycle also limits your options compared to the KoolMore with its 4 drying programs. At 90 kilowatt hours annual consumption, the energy efficiency is competitive.
Load Size Optimization for Drying Success
The COMFEE handles 26 pounds for washing but only 13 pounds for effective drying. This means you should fill the drum for washing but expect to remove half the load before the drying cycle for best results. Owners who follow this guideline report dramatically better drying performance.
Maintenance and Drum Care
To prevent the rust issues that some owners report, run a drum clean cycle monthly and leave the door slightly open between uses. Wipe the door gasket dry after each cycle. Check the coin trap weekly if you wash items with pockets. The inverter motor requires no maintenance beyond normal use.
8. Sekido All-in-One Ventless/Vented Washer Dryer – Best Pet Owners Pick
Sekido All-in-One Washer Dryer VENTLESS/VENTED PET cycle 1.62cf/15lbs 110V (Black)
- Dedicated Pet Cycle removes pet hair from fabrics
- Winterize cycle for RV and boat storage
- Dual ventless and vented capability
- Oversuds control prevents excess soap
- Child lock safety
- Smallest capacity at 1.62 cu ft
- Semi-automatic operation
- Limited drying cycles
- Low stock with only 10 left
The Sekido SK 4600 fills a niche that no other unit on this list addresses: a compact combo designed specifically for pet owners. The dedicated Pet Cycle uses specialized agitation and rinsing to remove embedded pet hair from fabrics. As someone who lives with two shedding cats, I found this cycle genuinely effective on blankets and pet beds.
At 1.62 cubic feet, this is the smallest capacity unit in our roundup. It handles about 15 pounds of laundry, which translates to roughly 4 to 5 days of clothing for one person. The trade-off for the small size is flexibility: the Sekido can operate in both ventless and vented modes depending on your installation.
The Winterize cycle is a standout feature for RV and boat owners. In just two minutes, this cycle prepares the machine for cold-weather storage by clearing water from internal lines and the pump. This prevents freeze damage and extends the life of the machine significantly for seasonal users.
The oversuds control automatically detects excess soap and adds extra rinse cycles as needed. This is particularly useful if you use high-efficiency detergent incorrectly or accidentally add too much. The touch button controls are simple and the ETL certification confirms electrical safety standards are met.
Pet Cycle Performance and Best Practices
The Pet Cycle works best on medium loads of pet bedding, blankets, and clothing covered in fur. Pre-shake heavily furred items before loading. Use a pet-safe detergent and avoid fabric softeners, which can irritate pet skin. The cycle runs approximately 90 minutes and includes extra rinse steps.
Ventless vs Vented Mode Selection
In ventless mode, the Sekido condenses moisture internally and drains it through the hose. In vented mode, you connect a 4-inch vent hose to exhaust moist air outside. Vented mode dries faster and uses less energy, but requires installation near an exterior wall or vent opening. Choose ventless for maximum installation flexibility.
How to Choose the Best All-in-One Washer Dryer?
Choosing from the best all in one washer dryers comes down to matching the machine to your specific living situation and laundry habits. Here is what our testing and owner feedback tell us matters most.
Capacity and load size directly determine how much laundry you can handle per cycle. A 2.7 cubic foot drum handles about 13 pounds of dry laundry for effective washing and drying. If you wash for a family of four, you will run multiple cycles per week. For singles or couples, 2.4 to 2.7 cubic feet is plenty.
Ventless vs vented technology is the most important decision. Ventless combos use a condenser or heat pump to dry clothes without external venting. This means you can install them anywhere with a water line and drain. Vented units like the GE Spacemaker dry faster but require a vent pipe to the outside.
Drying time expectations must be realistic. Ventless combos take 2 to 4 hours for a full wash-and-dry cycle, compared to 60 to 90 minutes for a separate vented dryer. Forum users on r/Appliances consistently emphasize this point: if you expect vented-dryer speeds, you will be disappointed.
Electrical requirements vary significantly. Most ventless combos run on standard 120-volt outlets, making them plug-and-play for apartments and RVs. The GE Spacemaker requires a 240-volt circuit like a traditional dryer. Always verify your electrical setup before purchasing.
Smart features and connectivity matter if you want remote control. The LG WM3555HVA offers Wi-Fi control via the ThinQ app, while most budget options like BLACK+DECKER and KoolMore skip smart features entirely. Decide whether app control is a must-have or a nice-to-have for your lifestyle.
Energy efficiency varies less than you might expect among ventless models. Most consume about 90 kilowatt hours annually, which translates to roughly $10 to $12 per year in electricity costs. The real energy savings come from eliminating the need for a separate dryer, which typically uses 3 to 5 times more power.
Noise levels during operation are a common concern for apartment dwellers. Inverter motor units like the Midea and LG run quieter than universal motor models. Expect wash cycles to produce a low hum similar to a bathroom fan, while spin cycles at 1400 RPM will be noticeably louder for about 10 to 15 minutes.
Frequently Asked Questions
Are all-in-one washer-dryer combos worth it?
All-in-one washer dryer combos are worth it if you have limited space, no dryer vent access, or want the convenience of not transferring clothes between machines. They cost more upfront than buying separate budget units, but they save floor space and simplify laundry. For apartments, RVs, and small homes, the space savings alone justify the investment.
What are the disadvantages of an all-in-one washer/dryer?
The main disadvantages are longer drying times of 2 to 4 hours per full cycle, smaller drying capacity compared to washing capacity, inability to wash and dry simultaneously (except stacked units like the GE Spacemaker), and higher upfront cost than separate budget machines. Some users also report more wrinkling since clothes sit longer in the drum.
How long does it take to wash and dry clothes in a combo unit?
Most all-in-one combos take 2 to 4 hours for a complete wash-and-dry cycle. Smaller loads of 6 to 8 pounds may finish in about 2 hours, while full loads of 13-plus pounds can take 3 to 4 hours. The drying phase is the longest part since ventless condenser drying is inherently slower than vented drying.
Do all-in-one washer dryers need to be vented?
Most all-in-one washer dryer combos on the market are ventless, meaning they do not require external venting. They use a condenser or heat pump system to dry clothes by collecting moisture internally and draining it through a hose. The GE Unitized Spacemaker is an exception that requires standard 4-inch dryer venting.
Can you wash and dry at the same time in a combo unit?
True all-in-one combos like the LG, Midea, and BLACK+DECKER cannot wash and dry simultaneously because they use the same drum for both functions. However, stacked laundry centers like the GE Unitized Spacemaker have separate washer and dryer compartments, allowing you to wash one load while drying another.
Final Thoughts on All-in-One Washer Dryers
Finding the best all in one washer dryers for your situation means being honest about your space, your laundry volume, and your patience for longer drying cycles. The LG WM3555HVA earned our top pick for its smart features, AI fabric detection, and AAFA-certified allergen removal. The Midea delivers the best value with its 10-year inverter motor warranty and Air Fluff anti-wrinkle feature. And the BLACK+DECKER offers a recognizable brand at a budget-friendly price point.
For RV and boat owners, the Smad and Sekido solve problems that no other units address with features like winterization cycles and dedicated pet hair removal. The GE Spacemaker remains the top choice if you have a 240V connection and want simultaneous wash and dry capability.
Set realistic expectations about drying time, keep your loads appropriately sized, and these machines will simplify your laundry routine for years to come. As we head through 2026, ventless combo technology continues to improve, and the models on this list represent the best options available right now.
