  • Publication number: 20140041149
    Abstract: A vacuum cleaner includes a base having a foot and a handle assembly pivotally coupled to the foot, and a canister assembly removably supported by the base. The vacuum cleaner also includes a first engagement member extending from one of the base and the canister assembly. The first engagement member engages the other of the base and the canister assembly to support the canister assembly on the base and inhibit the canister assembly from sliding side-to-side relative to the base. The vacuum cleaner further includes a second engagement member supported by one of the base and the canister assembly. The second engagement member engages the other of the base and the canister assembly to inhibit movement of the canister assembly away from the handle assembly when the canister assembly is supported on the base by the first engagement member.
