Robotic vacuum cleaner with removable dust container

1. A robotic vacuum cleaner, including:

a housing defining a dust container reception compartment that has a dust container reception opening in an outer surface of the housing;

a dust container configured to be removably receivable inside the dust container reception compartment via the dust container reception opening, such that,

in an operationally received condition, an outer push surface of the dust container is flush with the outer surface of the housing, while

in a removably received condition, the push surface of the dust container protrudes outwardly from said outer surface of the housing; and

a push-push mechanism that is configured to maintain a received dust container in said operationally received condition when the push surface of the dust container is pushed inwards into the housing and released a first time, and to force the dust container from said operationally received condition into the removably received condition when pushed inwards into the housing and released a second time.

2. The robotic vacuum cleaner according to claim 1 , wherein a top surface of the housing defines the outer surface of the housing in which the dust container reception opening is provided.

3. The robotic vacuum cleaner according to claim 1 , wherein the push surface of the dust container, protrudes at least 5 mm outwardly from said outer surface of the housing in said removably received condition.

4. The robotic vacuum cleaner according to claim 1 , wherein the dust container defines a circumferential region that, in said removably received condition, extends between a circumferential edge of the push surface of the dust container and a circumferential edge of the dust container reception opening in the outer surface of the housing, and

wherein said circumferential region defines a grip enhancing surface feature including at least one of a surface protrusion and a surface depression.

5. The robotic vacuum cleaner according to claim 1 , wherein, in the operationally received condition, the push surface of the dust container covers substantially the entire dust container reception opening.

6. The robotic vacuum cleaner according to claim 1 , wherein the push-push mechanism includes:

a first push-push actuator, having a first end that is fixedly connected to the housing, and a second end that is movable relative to the first end between a first position and a second position; and

a support arm that is connected to the second end of the first push-push actuator, such that the support arm is configured to maintain the dust container in the operationally received condition when the second end of the push-push actuator is in the first position, and the support arm is configured to maintain the dust container in the removably received condition when the second end of the first push-push actuator is in the second position.

7. The robotic vacuum cleaner according to claim 6 , wherein the support arm extends between a first end that is pivotally connected to the housing, and a second end that is configured to engage the dust container, and

wherein the second end of the first push-push actuator is pivotally connected to the support arm in between the first and second ends thereof.

8. The robotic vacuum cleaner according to claim 7 , wherein the second end of the support arm is forked such that it defines at least two prongs, and

wherein the dust container defines a support arm engagement portion that, in the operationally received condition of the container, is engaged between said at least two prongs.

9. The robotic vacuum cleaner according to claim 6 , wherein the push-push mechanism further includes:

a second push-push actuator, spaced apart from the first push-push actuator and having a first end that is fixedly connected to the housing, and a second end that is movable relative to the first end between a first and a second position;

wherein the support arm is connected to the second ends of the first and the second push-push actuators so as to synchronize said actuator's actions, and

wherein the support arm engages the received dust container at a point in between the second ends of the first and second push-push actuators.

10. The robotic vacuum cleaner according to claim 1 , wherein the dust container includes a first portion and a second portion, said portions being movably interconnected through the push-push mechanism, such that an outer dimension of the dust container is variable by pushing the push surface of the received dust container inwards into the housing and subsequently releasing it.
