Can be used anywhere with a standing water supply. No power supply required. Just "prime" the hose in the water which then sucks the water up the hose.
Brand new, never used.
Comes with instructions, brush head, extension pole, bucket clip, one way value, non-kink tube and hand held rubber wiper.
"No pumps, no taps and no tangled hoses. The unique patented one-way valve defies gravity. Clean your car with just one bucket of water. Use WashMatik to clean windows, doors, paintwork, patio doors and conservatories - even your boat or caravan"
Can post for £5
