Which is better for stain removal?

The Electrolux, because it has Perfect Steam and SmartBoost, which the LG lacks. The LG relies on 6Motion wash action and ColdWash, which are effective but less targeted at tough stains.

Both use durable direct-drive-style motors, and the Electrolux backs its motor with a 10-year warranty. LG's inverter direct drive motor has a long track record, but no warranty term was given here.

Is the Electrolux worth the extra money?

At $943.00 at Homery as of November 8, 2026, it is worth it if you want steam, a 15-minute cycle and app control. If you just need clean clothes, the LG covers that for less.

Which is better for a small space?

Both are 27 inches wide. The LG is stackable and listed at 30 inches deep, which suits closets and second-floor laundry rooms.

Which is more energy efficient?

The LG is Energy Star certified at about 100 kWh per year. No energy figure was given for the Electrolux, so the LG is the safer efficiency pick.

Do either have app control?

The Electrolux has app control. The LG WM3400CW has no app control listed.
