Cost and Benefits
Of course by increasing both productivity and reliability, there is an option to reduce human hours in the cleaning process that, on average, would generate an overall cost saving of 25%. It is important to note however that in the vast majority of our case studies, rather than reducing human hours, the free time generated has by used to improve the working or educational environment. Using robots also offers significant savings when pitted against a traditional tub vacuum – a saving of 62.5%.
Reducing Carbon Footprint
Experiments have shown using commercial robotic vacuums in e.g. offices can save over 11,000 tons of greenhouse gases each year compared to using traditional tub vacuums. A tub vacuum working for two hours had an electricity consumption cost of 1.44kWh. To fully charge a Hive of 10 robots took 0.54kWh of electric which would cover the same amount of space of 7,000sqft which is equivalent to a 62.5% electricity saving – not to mention savings made on vacuum bags and landfill.

Supporting Cleaning Staff
At TPLC we only use NiMH batteries in our products. NiMH are fully recyclable. With NiMH batteries product storage is simple and non-hazardous. Transportation conditions are also not subject to any regulatory controls. Many other robotics and vacuums contain Li-ion batteries. The technology used in Li-ion batteries is fragile and requires a protection circuit to maintain safe operation. Quicker aging is also a concern when it comes to Li-ion batteries. It is not recommended that a large number of Li-ion batteries are used within a close proximity to each other as one ‘popping’ could cause the neighbouring products to ‘pop’.
Li-ion battery use in robotics has also been responsible for some high profile commercial fires which is why we are committed to using only NiMH batteries in our products.
Our clients are finding the robots substantially safer and favourable to having trailing cables from the old traditional equipment. Caution signs are provided complimentary if vacuuming is completed when people traffic is high.
