A basic prototype of an
Air Recycling Cleaner was tested at Intertek in 2005. The outcome was
that a prototype cleaner using air recycling technology can outperform a
1,400 Watt vacuum cleaner.
In 2008 an Ecovacuum
project held at Brussels reported that vacuum cleaners are using too
much electricity and they are hoping to cap the amount of input electricity
that cleaners are allowed to use.
