Ventless all-in-one combos, stackable pairs, and 120V options that
fit where full-size laundry can't. Updated for 2026.
By Compact.com Editors · Last updated March 2026 · 14 min read
In-unit laundry is the most requested apartment amenity in the country,
and compact washer-dryer combos make it possible even without a dedicated
laundry closet. We compared the top models across three categories:
all-in-one combos (one machine does both), stackable compact pairs
(separate washer and dryer in a vertical footprint), and portable units
that run on a standard 120V outlet.

All-in-one vs. stackable: which setup is right for you?
An all-in-one combo uses one machine to wash and then dry your clothes
sequentially. This means a single load takes 3–5 hours but requires only
one appliance's worth of floor space and typically runs on 120V — no
special outlet needed. A stackable pair gives you separate machines
stacked vertically; loads are faster since you can wash and dry
simultaneously, but you'll need more vertical clearance and usually a
240V connection for the dryer.
Our Top Picks
LG WM3555HWA All-in-One Washer/Dryer Editor's Pick
Price: ~$1,600Type: All-in-one comboWidth: 23.6"Capacity: 2.4 cu ftVoltage: 120V
The LG combo is the most popular compact washer-dryer in the U.S. for
good reason. It runs on a standard 120V outlet, needs no external
vent (it uses ventless condensation drying), and fits in a closet or
under a counter. The wash cycle is excellent; the dry cycle is slower
than a dedicated dryer but gets clothes genuinely dry. At 2.4 cubic
feet, expect to do loads of roughly 8–10 items at a time.
Our take: Best all-in-one combo for apartments with no special electrical hookups.
Price: ~$1,350Type: All-in-one comboWidth: 23.4"Capacity: 2.4 cu ftVoltage: 120V
GE's entry is slightly more affordable than the LG and offers
comparable capacity and ventless drying. Build quality is solid, and
the plug-and-play 120V setup makes installation straightforward.
Drying times are a bit longer than the LG in head-to-head testing.
Our take: Strong value pick — similar performance to the LG at a lower price.
Bosch 800 Series Compact Pair (WGB246AXUC + WQB245AXUC) Most Popular Compact Pair
Price: ~$3,998 (pair)Type: Stackable pairWidth: 23.5"Washer capacity: 2.4 cu ftDryer capacity: 4.0 cu ft
The Bosch 800 Series is consistently the best-selling 24-inch
stackable pair in the US, and Yale Appliance's reliability data backs
it up with a 5.2% service call rate. The i-DOS system auto-doses
detergent and fabric softener so you never over- or under-use product,
and the heat pump dryer uses roughly 50% less energy than a
conventional electric dryer. Stacked, the pair occupies just 23.5 ×
25.5 inches of floor space — fitting a standard closet — and the
ventless design requires no dryer duct. Both units carry Energy Star
Most Efficient certification.
Our take: The benchmark compact stackable pair — best-selling in the US, ventless heat pump, and i-DOS auto-dosing.
Comfee CLV16N2AMG Portable Washer Best for Renters
Price: ~$330Type: Portable washer (no dryer)Width: 20.7"Capacity: 1.6 cu ft / 11 lbsVoltage: 120V
The CLV16N2AMG is purpose-built for renters who want a proper washing
machine without a permanent hookup. It connects to a standard kitchen
faucet and drains into a sink — no installation, no landlord approval
needed. The 11-lb capacity handles a week's worth of clothes for one
person across six programs (Quick, Normal, Delicate, Bulky, Heavy,
Spin Only). Built-in wheels and a top handle make it easy to roll out
of a closet when needed, then tuck away. Note: this is a washer only
— pair it with a drying rack or occasional laundromat dryer run.
Our take: Best no-install portable washer for renters — faucet-connect, 120V, six wash programs.
Miele's 160 Series pair offers something no other premium compact set
can match: a heat pump dryer that runs on a standard 120V outlet.
Most heat pump dryers — including the Bosch 800 Series — require 240V,
making them impractical in older apartments without a dryer circuit.
The TXD160WP eliminates that constraint entirely. The washer's
HoneyComb drum is gentler on fabric, and Miele's build quality earns
it the tightest service call rates in the category. About $700 less
than Miele's higher-tier WXR 860 line while keeping all the essential
technology.
Our take: Only premium compact pair with a 120V heat pump dryer — ideal for apartments without a 240V dryer circuit.
Most 120V combos connect to a standard grounded outlet and hook up to
your kitchen or bathroom sink faucet for water supply and drain. Some
can also connect to permanent plumbing if available. Check your lease —
many landlords allow portable units since they require no permanent
modifications. For stackable pairs requiring 240V, you'll likely need
landlord approval and possibly an electrician.
