Commercial robot vacuums could save 11,000 tonnes of greenhouse gases in England and Wales each year, according to a recent experiment conducted by The Perfect Little Company (TPLC).
TPLC used a certified power metre reader to monitor the electricity needed to operate a well-known commercial mid-sized tub vacuum and a hive (10 robots).
The tub vacuum consumed 1.44 kilowatt hours (kWh) of electricity during two hours in operation. The 10 robots were fully charged using 0.54kWh of electricity. Both the hive and the tub vacuum covered around 7,000 square feet.
TPLC said: "In London alone (which has over 200 million square feet of office space) this would equate to reducing the carbon output of vacuuming by a massive 2,700 tons a year. Additionally, this would save on the costs of vacuum bags, landfill and electricity.
"On average 12 tons of CO2 is produced per million sq ft of office space every year just by the electricity used to vacuum. This could be reduced by circa 60 per cent by simply switching from a traditional vacuum to robotic vacuums."
David Hardwood, site deployment manager at TPLC, said: "We knew that using the robots is cost-effective regardless, but we were intrigued to establish if there was an additional saving where electricity is concerned to ensure our products are as eco-friendly as possible.
"We were pleasantly surprised and pleased to establish officially how much electricity could be saved too. From an environmental impact point of view this is an incredible bit of news for us and our customers."
