Could Dolfi replace the washing machine?
The washing machine's days could potentially be numbered, if a new invention from Germany really takes off.
Dolfi - invented by Lena Solis - is a small electronic device that uses ultrasound waves to break stains down. The gadget can fit in the palm of a hand and it is claimed that Dolfi uses around 80 times less energy than a normal washing machine.
"Inspired by amazing benefits of ultrasound, successfully utilized for years in many industrial and medical applications, we’re excited to bring the advantages of ultrasonic precise cleaning to everyday personal use," Ms Solis said.
"I believe that ultrasonic technology will change the way we wash," she added.
Ms Solis was inspired to create the device after struggling to find somewhere to wash clothes while travelling. Dolfi is therefore designed to work in a sink and it is claimed that the device can clean clothes within 30 minutes without the need for scrubbing and wringing.
The project will be crowdfunded via Indiegogo and those who provide a donation of $89 (£60) will receive their Dolfi once the devices have been manufactured.
