The only reason households up and down the country do not have a dishwasher is space. Dishwashers are hygienic, use less water than hand washing and are incredibly convenient.
The dishwasher connects like any other plumbed dishwasher, but can also be fitted to a kitchen tap, as long as you can connect the standard water hose (with most taps you can simply unscrew the aerator) and connect a suitable adaptor such as 3/4″ x 1/2″ bush or 22mm x 3/4″ coupler (depending on your tap and if and what aerator it has. The adaptors are widely available and cheap from any hardware store. Scroll through the photos if you are unsure what an aerator is).
The waste pipe can also be plumbed in (max elevation 60cm) or even aimed down the sink. The 6 place settings make it more than enough for bachelors, couples and small families, just look through the photos and check out the place settings diagram!
