electriQ 40L Smart Laundry Dehumidifier Review: price, specs and verdict (2026)

With a 6-litre tank and continuous drainage support, this is designed to run for extended periods without manual emptying, provided the drainage hose is connected to a nearby outlet. The smart app is the main way to manage it day-to-day: set a target humidity, check progress remotely, and schedule operation around when the space is actually in use — useful for a gym or office that only needs full drying during opening hours.

The laundry mode is pitched as more energy-efficient than running the unit on a standard setting for the same job, gently removing moisture from fabrics rather than blasting airflow at full power throughout. As with any large-capacity unit, actual running cost will be noticeably higher than a 12-20L domestic model — electriQ doesn't publish a wattage figure for this listing, so budget for a commercial-scale electricity cost rather than the pence-per-hour figures quoted for smaller units in this comparison.

The 40L Smart Laundry sits above the 30L Industrial in electriQ's range, adding smart app control on top of the same basic promise: genuinely large-scale moisture removal for a space that has outgrown a domestic 20L unit. The listing highlights use in large homes, gyms, offices and pool areas — anywhere a constant, high level of humidity needs continuous management rather than an occasional top-up.

Unlike the manually-controlled Industrial model, this one connects to a smartphone app for remote monitoring and scheduling, so humidity can be checked and adjusted without being in the room. A built-in humidistat maintains a chosen target automatically, with auto shut-off, a 24-hour timer and continuous drainage rounding out the feature set. A child lock is included, a detail more common on domestic units than commercial-capacity machines.
