Features & Performance

TurboWash 360 helps clean large loads more thoroughly without extending wash time unnecessarily

AAFA-certified Allergiene cycle uses steam to remove over 95% of pet dander and dust from bedding, clothing, and more
TrueBalance anti-vibration system and LoadSense help keep larger loads balanced and the machine running quietly
Sensor Dry automatically adjusts drying time based on detected moisture, helping protect fabrics and save energy
ThinQ Wi-Fi connects with Alexa and Google Home, plus Proactive Customer Care for maintenance tips and alerts
Up to 1400 RPM spin is fast for a compact all-in-one combo
Tempered glass door and full stainless steel tub add durability and a premium look

This unit focuses on premium, smart-assisted, space-saving laundry rather than maximum capacity. It is designed for apartments, condos, and small households that want a single ventless machine loaded with the latest LG washing and AI technology.

Reality check: As a ventless all-in-one combo, this unit dries using condensation rather than an exhaust vent, which makes installation easier but generally takes longer than a vented dryer, especially on the combined Wash+Dry cycle for larger or heavily soiled loads. At 2.4 cu ft, it's best suited to individuals, couples, or smaller households rather than large families. Smart features like ThinQ remote control, Proactive Customer Care, and Alexa/Google Home integration require connecting the unit to Wi-Fi and the LG ThinQ app.

Who Should Buy This?

Apartment and condo dwellers without dryer venting who want a premium all-in-one
Buyers who want AAFA-certified allergen reduction via the Allergiene cycle
Smart home users who want ThinQ, Alexa, and Google Home integration
Anyone who wants a fast 1400 RPM spin in a compact combo

Who Should Avoid This?

Large families with heavy daily laundry volume
Buyers who want the fastest possible wash-and-dry turnaround
Anyone who doesn't want a Wi-Fi-connected appliance
Households with space and hookups for separate full-size washer and dryer units

Pros & Cons

Cons

2.4 cu ft capacity limits large loads
Ventless combo wash-and-dry cycles take longer than separate units
Smart features require Wi-Fi and the LG ThinQ app
Already an all-in-one unit, so it isn't part of a separate stackable pair

Single dryer program relies on Sensor Dry within combined cycles

Installation Notes

Requires a 120V, 15-amp outlet plus hot and cold water supply and a drain — no external venting needed
Footprint is 24"W x 33.5"H x 22.25"D; measure your space including clearance for the door
Remove all transport bolts before first use to prevent excessive vibration
Connect to home Wi-Fi and the LG ThinQ app to use smart features
Place on a level, solid floor for stable operation

Always verify dimensions and installation requirements before buying. Appliance returns are expensive and inconvenient.

Frequently Asked Questions

Does it need a dryer vent?

No, this is a ventless all-in-one combo that uses condensation drying, so it can be installed without external venting — a good fit for apartments and condos.

How long does a full wash and dry cycle take?

Ventless combo wash-and-dry cycles generally take longer than running a separate washer and dryer, especially for larger or heavily soiled loads. Exact times vary by cycle and load size.

Is it worth buying?

For apartments or small spaces that want a premium, feature-rich all-in-one with AAFA-certified allergen reduction, AI-assisted washing, a fast spin, and smart connectivity, this is a strong pick. Larger households or anyone wanting the fastest possible turnaround should consider separate full-size washer and dryer units instead.
