LG Electronics is launching the robot vacuum "LG Hombot AI Objet Collection RONi" (RONi), which applies a 100℃ steam function to both the main unit and the station. The company plans to target the premium robot vacuum market by strengthening cleaning performance, hygiene management, and interior design.
LG Electronics said on the 29th it will release RONi in two types: the automatic water supply and drainage "Hidden Station" and the water tank "Objet Station." The shipment price for both models is 2.19 million won. Starting on the 2nd of next month, the product will be available for purchase through LG Electronics Best Shop, Coupang, and other online and offline channels.
The Hidden Station is installed in the kick space under a kitchen sink. With a station height of 15 cm, it can use the existing kick space without additional lower-cabinet construction. The Objet Station uses a side-table-style design, allowing it to be placed independently in spaces around the home such as the living room and bedroom.
Both models enter and exit through an automatically opening and closing front door on the station during cleaning. Normally, the door remains closed so the robot vacuum main unit is not exposed. It won the top product award at the "2025 Ergonomics Design Award" hosted by the Ergonomics Society of Korea.
RONi is the first in the world to apply a 100℃ steam function, based on the outlet, to both the main unit and the station. During cleaning, it sprays 100℃ steam onto the mop to remove floor stains. After cleaning, the station washes the mop with 100℃ steam and hot water.
According to LG Electronics, RONi removes 99.99% of four harmful bacteria—Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli—during the mop washing process after cleaning. After washing, it uses warm air to dry the mop, reducing odor-causing substances by up to 97%. The patented "Station Conditioning" technology, which expels internal moisture through a top exhaust fan, is also applied.
Cleaning performance is based on 30 W suction power and a mop that rotates 180 times per minute. When cleaning corners, the side brush extends to about 46 mm to gather dust in corners toward the central intake. The intake features a dual brush that reduces hair tangling.
An artificial intelligence (AI) object recognition function is also applied. RONi analyzes spatial structures using LG Electronics' self-developed AI object recognition technology and eight sensors installed in the main unit. It distinguishes more than 120 types of objects, such as cables, flowerpots, and pet excrement, to avoid obstacles and remove contaminants according to the cleaning method.
It also has a function to distinguish spaces in the home, such as the living room, kitchen, and bedroom. In areas like the kitchen where food often falls, it sets a denser driving route and increases suction power. The location of obstacles is guided to users via the LG ThinQ app, and when obstacles are removed, it cleans the area again.
RONi is equipped with LG Electronics' proprietary security system "LG Shield." It encrypts collected data and stores encryption keys separately. After cleaning, the station door closes, reducing concerns about camera exposure. Through this, it also received the "privacy by design" (PbD) certification from the Personal Information Protection Commission.
LG Electronics will provide an initial purchase welcome kit that includes a maintenance agent, dust bags, and mops. Subscription purchasers can receive free after-sales service (A/S) and regular visits from care specialists. Key consumables such as mops and batteries are also replaced according to the schedule.
Son Chang-woo, head of the Living Solution Business Unit at LG Electronics, said, "By applying 100℃ steam to both the main unit and the station, we will strengthen hygiene management and provide a differentiated user experience with a design that suits residential spaces."
