Benefits of technology

The present invention provides a pool cleaning robot with a motor-carrying module that can be easily removed and replaced without disassembling the robot. The robot has a frame with a hollow for receiving a filter bag and a module carrying portion for attaching a motor-carrying module. The motor-carrying module can be sealed and detachably attached to the frame. The robot can also have wheels and tracks for retention of the wheels. The invention also provides a filter unit with a bottom panel and a frame for easy installation and replacement of the filter bag. The robot can also be designed to propel itself along a trajectory in the direction of its axis of symmetry. The robot can also have a weight imbalance and a module carrying portion for attachment of a filter unit. The invention also provides a pool cleaning robot that can climb a sidewall of a pool and a filter unit that can be easily installed and replaced.

Problems solved by technology

In addition, the motion of the track imparts a rotation to the brushwheels, which scrubs the surface of the pool.
