Best Overall: LG WM3488HW All-in-One Front Load Washer and Electric Ventless Dryer Combo

Buy on Amazon Buy on Home Depot

Turn laundry into a one-step process with the LG WM3488HW. This top all-in-one washer dryer is small but efficient. The drum has a capacity of 2.3 cubic feet, which is about average for combination washer and dryer machines. What sets this model apart is its reliable performance, variety of wash and dry cycles, and relatively speedy cycles. 

The LG WM3488HW includes nine wash cycles with specialty options for hand-washed garments, or sanitizing them using a cycle that heats the water to 158 degrees and eliminates stains, odors, and bacteria. Once the wash cycle is complete, the machine will kick into dryer mode. Like most combination units on the market, this model has a ventless dryer that needs no external ductwork. 

An average wash and dry cycle lasts between 2 and 4 hours, depending on the options selected. Some machines on the market stretch this time to as much as 6 hours, so this model is a good choice if you want to do multiple loads in a day. It also will perform well, even when tasked with drying surprising items like thick, fluffy pillows and dog beds. 

You may notice the machine shaking or vibrating excessively during a spin cycle, but this is often remedied by using rubber pads under the feet and making sure the machine is leveled properly. Otherwise, this all-in-one washer-dryer does a great job of making your dirty laundry disappear with as little user intervention as possible. You’ll still need to fold your clothes when the cycle is complete, though—that's inevitable.

Best with Steam: LG WM3499HVA 2.3 cu. ft. Smart Compact All-In-One Washer and Dryer

If you’re specifically searching for an all-in-one washer with steam, the LG WM3499HVA is a well-loved option. This machine includes seven cycles and LG’s steam technology which eliminates allergens and odors. The Allergiene cycle is LG’s one-touch solution for eliminating up to 95 percent of the household allergens most likely to cause a reaction. The steam feature also provides an effective yet gentle way to remove stains from your clothes.

This all-in-one washer with steam is an average size for combination units and gives you 2.3 cubic feet of drum space. While it isn’t as roomy as some large-capacity all-in-one washers, it fits easily into a closet or under your kitchen counter. You may need to deal with some extra noise or vibrations coming from this model. Overall, you'll likely be satisfied, though, with how well it washes and dries, and exceeds any past experiences you've had with an all-in-one washer dryer.

Best Large Capacity: LG Electronics WM3998HBA Ultra Large Capacity Electric All-in-One Washer Dryer Combo

Buy on Home Depot Buy on Ajmadison.com

If you’ve been hesitating on buying an all-in-one washer and dryer because of the small drum size, then spring for LG Electronics WM3998HBA. The full-size drum is 4.5 cubic feet, so you can tackle tons of dirty clothes at one time. Now, if you toss in a smaller load, you'll likely have clean, ready-to-wear clothes quicker. However, if you're not in a rush, put a regular load of T-shirts, jeans, and sweats into this machine and expect to have clean and dry garments at your disposal in about three and a half hours.

This machine uses LG ThinQ technology, so it'll alert you when a load is done in the washer via an app on your phone. From there, you can tell it to start one of three dryer cycles including permanent press, damp dry, and auto dry. Notably, the WM3998HBA has some specialty washing cycles including one for bedding, activewear, or those who suffer from allergies and asthma. Although it doesn't allow the use of detergent packs, the added smart technology and black steel exterior makes this appliance an easy addition to your home.

Best Smart: LG Signature LUWM101HWA Smart Wi-Fi Enabled Washer and Dryer Combo

If you are looking for an all-in-one washer and dryer that is smart enough to keep up with your other smart home gadgets, consider the LG Signature All-in-One Washer and Electric Dryer.

This appliance features a modern aesthetic that will blend into many homes filled with high-tech devices. The control panel is a digital touchpad that blends into the door of the unit. Swipe left and right to access the full control menu. Users report that the touchpad is easy to use—just make sure that your fingers are dry since it’s a capacitive touchpad that won’t recognize wet hands. Even more exciting, fans of home tech will love the unit’s ability to be controlled by a smartphone. Simply download LG’s smartphone app and connect the appliance to WiFi to remotely start and monitor the machine. The LG Signature combo washer and dryer also will automatically dispense detergent based on load size—and alert you when the supply is running low.

The capacity of this particular washer and dryer combo is 2.8 cubic feet—which is on the upper end of the average capacity size for these machines. But even better is the fact that this washer and dryer unit is compatible with the Sidekick Pedestal Washer made by LG. So if you’re looking for additional wash capacity, add on the pedestal and run two wash cycles simultaneously. Note, however, that the Sidekick Pedestal Washer won’t automatically dry your clothes—that’s reserved for the main wash drum only. Overall, this all-in-one washer and dryer from the LG Signature line delivers the latest in smart home technology combined with an easy, thorough washing and drying experience.

Best for RVs: Splendide WD2100XC White Vented Combo Washer and Dryer

Buy on Amazon Buy on Walmart

The Splendide WD2100XC is especially popular for use in RV’s but also works well in small homes or apartments that won’t accommodate a full-size washer and dryer. Just keep in mind that this is a vented all-in-one washer and dryer, so you’ll need to make sure you can connect the machine to an external vent hose. 

The machine measures a little more than 3 feet high and is less than 2 feet wide. The manufacturer reports its washing capacity as 15 pounds, while the drying capacity is a little less at 11 pounds. Keep this in mind if you want the machine to seamlessly transition into its auto-dry function. Reviewers generally find it to be reliable and a great option for keeping small loads of laundry from piling up. However, other users caution that you’ll need to commit to regular maintenance cleaning for the best performance from this machine. Since there’s no lint screen, you’ll want to regularly clean the internal vent line and external vent hose. This isn’t uncommon for all-in-one washers and dryers, but it is something to be aware of.

Best Compact: GE GFQ14ESSNWW 2.4 cu. ft. High-Efficiency Ventless Electric All-in-One Washer Dryer Combo

Fit a washer and dryer just about anywhere with this compact, high-efficiency appliance from GE. It has all the bells and whistles of a larger appliance, like steam and sanitize cycles that'll deep-clean your clothes, and 14 different dry cycles. You can toss a detergent pack in with your load if you'd like, before you start relaxing on the couch of your small apartment, condo, or RV. Its 2.4 cubic-foot drum is also large enough to fit your dirty clothes after a few days.

The GE GFQ14ESSNWW is well-under 3 feet tall and only about 2 feet wide, which means it can easily slip into a closet. Despite its small size, it packs a big punch and will deliver dry, not slightly damp, clothes. This appliance's Auto Wash and Dry mode uses your chosen washer setting to decide the cycle your clothes, towels, or sheets should be dried at. If you aren't so quick to trust its judgement, though, you can also choose a setting manually.
