News editors obtained the following quote from the background information supplied by the inventors:“The robotic vacuum cleaner market has grown hugely over the past decade. Changes in lifestyle, increaseddisposable income, urbanisation and growing focus on labour-saving devices are some of the factors thathave boosted market growth, and the trend seems to be set to continue.“Whilst the robotisation of vacuum cleaners has seen more products enter the market, the form factorof such robots has not tended to diversify. Generally, robotic vacuum cleaners available on the marketare discoidal in shape, with a low height so they can travel underneath furniture in order to clean there.The main technological developments have focussed on improving navigational capabilities to improveautonomy, bin emptying systems and run time. In the main, however, the robotic vacuum cleaner marketincludes many generally circular machines that offer very little in terms of differentiation.
