  • a chassis comprising a fore-aft axis and a perpendicular transverse axis;

    a cleaning apparatus, attached to the chassis and defining a cleaning zone, comprising an air moving system, wherein the air moving system comprises a fan assembly configured to generate a negative pressure and a positive pressure, and comprising conduits applying at least one of the negative pressure and the positive pressure to a channel formed in the lower surface of the chassis of the autonomous cleaning robot;

    a waste storage container removably coupled to the chassis, wherein the air moving system comprises an air jet port that expels air substantially parallel with the transverse axis; and

    ,a first debris guiding strip disposed aft of the channel, the first debris guiding strip configured to direct loose particulates moved by air expelled from the air jet port toward an air intake port and including a first portion disposed aft of the air jet port and a second portion disposed aft of the air intake port.
