Soniclean Releases STV-3 Cordless Vacuum with Auto-Empty Base Station

Soniclean has released the new STV-3 Cordless Vacuum Cleaner with Auto-Empty Base Station — the brand’s first cordless model to feature a self-emptying dock. The STV-3 is designed to offer strong suction power, advanced H13 HEPA filtration, and added convenience for everyday cleaning.

Powerful Suction and Smart Cleaning Features

High-Performance 500W BLDC Motor with 35kPa Suction Power

The Soniclean STV-3 uses a high-speed 500-watt BLDC motor that delivers up to 35kPa of suction, with three cleaning modes: 10kPa (Low), 20kPa (Medium), and 35kPa (High). The power settings can be toggled via thumb controls on its digital display.

Auto-Empty Base Station for Hygienic Dust Disposal

For debris disposal, the auto-empty base station functions as a vacuum for the vacuum itself—transferring dust and debris from the handheld unit into a disposable H10 HEPA filter bag, while the base station itself includes an H13 HEPA exhaust filter The base also automatically cleans the filter screen and cyclones inside the vacuum, while charging the battery at the same time.

Advanced H13 HEPA Filtration and Dust Detection Technology

Dual HEPA System for Cleaner Air

Both the vacuum and the base station use H13-grade HEPA filters, which capture up to 99.97% of fine dust and allergens. The STV-3 features a triple-layer HEPA system — an H10 HEPA bag in the base station for debris collection, plus H13 filters in both the vacuum and the base station for exhaust filtration.

Optical Dust Sensor for Real-Time Cleaning Feedback

An optical dust sensor detects debris in real time, displaying “Dust Detected” on the screen while cleaning. When the light turns green, the surface is clear—an uncommon feature for a cordless vacuum in this price range.

Design, Accessories, and Safety Features

Lightweight Build for All Floor Types

Weighing just 5.7 pounds, the Soniclean STV-3 is designed for maneuverability and all-floor use. Its hybrid brush roll works across hard floors and carpets, and the detachable battery supports extended cleaning sessions. The model is available in Argent Silver and Pink Sapphire, the latter part of Soniclean’s Clean for the Cure edition.

Included Tools and Smart Safety Sensors

Included accessories are a 2-in-1 dusting brush, crevice tool, mini motorized powerhead, and telescopic wand. It also comes with two H10 HEPA filter bags, an H13 HEPA filter for the vacuum, and an H13 HEPA filter for the base station. Built-in safety sensors detect airflow blockages and brush roll jams to help prevent damage and maintain optimal performance.
