Abstract
A robotic cleaning head (1; 101) for use as part of an autonomous vacuum cleaning system (2) including a canister unit (3) and a hose assembly (4; 104) connecting the cleaning head (1; 101) to the canister unit (3). The cleaning head (3) has a chassis (5; 105), a drive system (6; 18; 27), a vacuum cleaning nozzle (8; 108) and a conduit (9; 109). The conduit (9; 109) communicates with an air passage bound by the cleaning nozzle (8; 108). It is suspended pivotable about a pivot axis (10; 110) and includes an inlet (11; 111) provided on top of said chassis (5; 105), and an elbow section (12; 112) downstream of the inlet (11; 111), and the conduit (9; 109) is suspended and shaped such that a line of action (15; 115) of a tension force (20; 120) exerted by the hose assembly (4; 104) onto the chassis (5; 105), via the conduit (9; 109) to which the hose assembly (4; 104) is connected, extends spaced below a downstream end of the elbow section (12; 112).
