Benefits of technology

[0014] According to a still further aspect of the present invention, there is provided a wheel adapted for use with a pool cleaning robot and adapted to be received by a frame of the robot. The wheel comprises a longitudinal axis along its length, a track receiving portion, and a guide portion. The guide portion is disposed adjacent the track receiving portion and comprises a groove, adapted to the carried by a notch of the pool cleaning robot, and a rim adapted to prevent dislocation of the wheel from the notch along the axis.

Problems solved by technology

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

A pool cleaning robot comprising a frame, at least one inlet, at least one outlet, and a motor carrying module. The robot further comprises a filter unit mountable to the frame. The filter unit has a filter bag with an inlet facing surface and an outlet facing surface. The robot further comprises a filter cavity formed between the outlet facing surface of the filter bag and the frame. The frame has an open area above the cavity. The open area faces the outlet and is designed for the insertion therethrough of the module into the filter cavity when the filter unit is mounted to the frame.

Description

FIELD OF THE INVENTION [0001] This invention relates to devices for cleaning swimming pools, basins, and the like. More particularly, the invention relates to an automatic self-propelled cleaning robot. BACKGROUND OF THE INVENTION [0002] Pool cleaning robots which automatically scan the floor and / or sidewalls of a swimming pool are well known in the art. These units are powered internally, by one or more battery packs, or externally, by way of a power cable. A robot of this type typically comprises a drive motor, a pump motor with an impeller, a filter, brushwheels, and a track. All of these components are contained within a housing. The housing comprises inlets at the bottom, and an outlet at the top. The robot comprises several sections, which permits at least partial disassembly of the robot. [0003] The drive motor drives the track, which propels the robot. In addition, the motion of the track imparts a rotation to the brushwheels, which scrubs the surface of the pool. [0004] The...
