Abstract
A cleaning unit for collecting debris in a swimming pool has a hollow main body that is pivotally connected to a leading end section. The leading end section and the main body may pivot through about 10.degree. when in an operative configuration to accommodate curvature of a wall or floor of the swimming pool. The leading end section and the main body are kept in the operative configuration by fingers. The fingers extend from the leading end section into the main body and may be disengaged so that the leading end section may be folded over. The main body defines a mouth at its front end and houses a bag in which debris is collected. When the leading end section is folded over the bag may be removed for cleaning and re-inserted. The leading end section has a tubular conduit which is connectable at its leading end to a supply hose. The tubular conduit carries a displacing jet for displacing the unit. Two wing-like triangular extensions are secured to the conduit so that the leading end section has a substantially triangular profile. The leading end section and the main body carry wheels at their peripheries.
