Improved memory performance in the machines is spurring a big growth in interest in robotic vacuum cleaners.
That's according to a firm of technology sector analysts, who believe that sales will rise by 16 per cent annually worldwide over each of the next five years.
TechNavio believes that robotic vacuum cleaners will make major breakthroughs into mainstream markets around the world, including the United States, the UK, Japan and China.
A spokesman for TechNavio told industry journal Azorobotics.com that new technology, enabling a robotic vacuum cleaner to resume cleaning from a particular spot after it had been switched off was a particularly important development which would boost sales.
"The introduction of room memory in these vacuum cleaners enables them to return to the same spot at which they stopped cleaning before they returned to the recharging point," he said.
"In addition, the room memory also enables these vacuum cleaners to remember the layout of the room."
Pressure on householders' time, leaving them with less for carrying out domestic chores, would also be an important factor driving growth, the spokesman added.
