LG’s RONi Uses 100°C Steam Twice, Cleaning Floors and Its Own Dock

LG has introduced HomeBot AI Objet Collection RONi, a robot vacuum built around an unusual promise for premium home cleaning: 100°C dual steam sanitation. The system is designed not only to help during mopping, but also to clean the robot and its docking station after each session.

That approach places RONi in a category aimed at solving two problems at once. It tackles stubborn dirt on the floor while also addressing the less visible issue of keeping the unit itself hygienic, an area where many robot vacuums still leave maintenance to the user.

Steam cleaning that continues after the job is done

RONi’s 100°C system works in two stages. During mopping, steam is sprayed onto the mop pad to help loosen difficult dirt and improve cleaning performance.

Once the cleaning cycle ends, the station washes the mop with 100°C steam and hot water. LG says this process can eliminate up to 99.99 percent of four common harmful bacteria.

The station also uses warm-air drying to help reduce odor-causing substances. A conditioning system then removes remaining moisture so the dock stays cleaner after the mop-washing process.

Two versions for different home layouts

LG is offering RONi in two versions with very different installation concepts. Hidden Station is made to fit under a kitchen sink kickboard, using a docking station that stands 15 cm high.

This model supports automatic water supply and drainage without requiring additional cabinet modification. It is intended for homes that want to keep the cleaning system out of sight and preserve a tidy floor area.

The second version, Objet Station, is a standalone model inspired by a side table. It can be placed in different areas of the home without being built into a cabinet.

Both versions include an automatic front door on the station. The door opens when the robot enters or exits, then closes again when the device is not in use so the unit remains hidden.

That design also supports privacy. After cleaning is complete, the robot’s camera stays behind the closed station door instead of remaining exposed in the room.

Premium cleaning hardware and AI navigation

Beyond sanitation, RONi is equipped with premium cleaning hardware. It has 30W suction, while the mop pads rotate at 180 rpm.

LG also added a side brush that can extend by about 46 mm to reach corners. A dual-brush system is used to help reduce tangled hair during cleaning.

For navigation, LG relies on AI-based object recognition supported by eight built-in sensors. The system can identify more than 120 types of objects, including cables, flower pots, and pet waste.

This matters because robot vacuums often struggle with small obstacles scattered across the floor. RONi can also notify users about obstacles through the LG ThinQ app, then return automatically to areas that were skipped once the obstruction is removed.

LG says the robot can adjust suction strength and cleaning patterns according to the room. In areas such as kitchens, the cleaning intensity increases to match heavier dirt conditions.

Security, pricing, and availability

LG Shield is included to protect user data. The system encrypts collected data and stores the encryption key separately, reflecting the fact that modern robot vacuums often rely on sensors and cameras to map the home and recognize objects.

Sales of RONi begin on July 2 through LG Best Shop, LG’s online store, and Coupang. There is still no confirmation on whether the device will be sold outside South Korea.

Hidden Station and Objet Station are both priced at KRW 2.19 million. Early buyers who purchase between July 2 and July 15 will receive a welcome kit, while selected customers who leave a photo review will get an additional gift.
