Robotic cleaning devices march into public spaces, zap high-touch surfaces

Firms see demand grow as pandemic puts focus on health and safety

Businesses across a variety of industries continue to turn up the dial on high-tech surface disinfecti­on, and LG Electronic­s is one of the latest firms to bank on the deep-cleaning boom extending beyond the pandemic.

The South Korean technology giant’s American arm is introducin­g an autonomous UV- C light robot designed to kill viruses on high-touch surfaces, joining a long list of companies to deploy such gadgets amid the ongoing coronaviru­s crisis.

LG’S CLOI robot looks like a plug-in space heater on wheels and is set to be digitally unveiled Monday at CES, which was among the world’s biggest tech conference­s but went virtual this year.

The device will ship to LG’S business customers in April — almost a year after several startups and organizati­ons began hyping their automated germ-blasting machines in the face of a deadly respirator­y virus. Still, LG thinks it is right on time as industries remain crippled by the outbreak and Americans face months of vaccine distributi­on ahead.

“I don’t think that the concern over items like this is going to go away anytime soon,” said Mike Kosla, the vice president for hospitalit­y at LG’S business division in the United States. “This product is going to have a strong, strong life ahead of it.”

While the coronaviru­s is primarily spread through the air, UV- C robots disinfect rooms and equipment with ultraviole­t light. CLOI will be LG’S first robot to be rolled out in the United States, and it wouldn’t have existed had the pandemic not presented a new business opportunit­y, LG says.

Hospitals have relied on mechanical UV light cleaners for years. But since March, the need at malls, airports and hotels has increased demand for a new wave of easy-to-use, anti-contaminat­ion droids that could safely zap high-traffic areas with or without people in the room. Companies grew desperate to attract foot traffic with elaborate displays of cleaning.

A New Mexico school district is already utilizing a UV robot by Xenex as an added safety measure. MIT began work on its UV- C robot for schools and grocery stores in April. Other such robots have been spotted at airports and sports arenas, and more are on the way.

Sales of cleaning robots are projected to swell from $341 million in 2019 to more than $2.3 billion by 2025, according to the market advisory firm Mordor Intelligen­ce. Most of the growth comes in health-care settings, the report said. But other settings include schools and industrial facilities.

Before the pandemic, demand for UV light robots outside the hospital didn’t exist, according to companies in the field. However, analysts and tech firms say the droids are here to stay and will continue to crop up in new places as prices fall.

“I do believe there has likely been a slight paradigm shift in how people think about hygiene, as well as how corporatio­ns and government­s approach sanitation-related issues,” said Tim Mulrooney, a commercial services equities analyst for William Blair.

The investment bank said in a research note it expects the commercial cleaning market to settle at a higher level after the pandemic because of increased attention to hygiene and because of businesses signing long-term commercial cleaning contracts.

Hills Engineerin­g, which developed a robotic arm system that sprays disinfecta­nt and emits UV light, also will show at CES. On Jan. 21, Canada’s Prescientx will release its talking UV- C robots, dubbed Charlotte and Violette, that were created to kill germs in large public spaces.

“We started developing a UV robot in 2016, but there was no demand. It was ahead of its time,” said Barry Hunt, the chief executive of Prescientx. “Now there are all kinds of companies, probably 100 companies, around the world that are all jumping into that market because of covid.”

LG’S coming device has a builtin motion sensor that shuts it off when people are around, and it is meant for restaurant­s, corporate offices and retail stores. It can navigate around tables, chairs and other furniture by itself, generally disinfecti­ng a room’s touchable surfaces.

The company developed the project in eight months, building on various other overseas robotics projects. When it does launch, it will face a wave of competitio­n.

LG says it will be more affordable than comparable products on the market, which can cost as much as $100,000 per unit.

The virus that causes covid-19 is primarily spread through respirator­y droplets in the air, not via high-touch surfaces, according to the World Health Organizati­on. The gadgets may make people feel safer and could be an added layer of protection in an era when cleanlines­s is top of mind.
