The present invention relates to pool-cleaning robots. More particularly, the present invention relates to a pool-cleaning robot with a visual display.
Swimming pools and similar water reservoirs require frequent cleaning. Manual cleaning of the pools involves tedious and intensive labor, making autonomous robots for cleaning pools an attractive alternative. The use of pool-cleaning robots for gathering dirt, debris and the like, together with other features such as scrubbing pool surfaces and disposing of moss, makes the pool-cleaning robots a tool sought after by pool owners and caretakers alike.
Pool-cleaning robots, e.g., autonomous pool-cleaning robots, are typically designed to scan and map the pool's floor and walls, creating an optimized path, generally using a form of artificial intelligence algorithm, for traversing the pool's area. After the path is calculated these robots sweep and brush the floor and side wall surfaces of the pool, catching debris and dirt found on the pool's floor and walls or floating in the pool's water, by pumping the surrounding water and dirt into a debris trap located inside the by the robot, using the robot's pump. The derbies and water sucked by the robot generally go through a water filtering chamber.
While the operation of a pool-cleaning robot may be fully automatic, owners of pool-cleaning robots may be interested to observe their robot, observe it working and even remotely operate the robot (e.g., change its direction of motion, change the sweeping pattern it follows, or having the robot end the cleaning task and return to them for removal from the pool and putting it away).
It may be desired to have a pool-cleaning robot with a visual display that is configured to provide visual indications relating to the operation of the robot, so as to allow the user of such robot located outside (or inside) the pool to determine the current action or actions that the robot is performing or is about to perform.

The terms “plurality” or “a plurality” may be used throughout the specification to describe two or more components, devices, elements, units, parameters, or the like. Unless explicitly stated, the method embodiments described herein are not constrained to a particular order or sequence. Additionally, some of the described method embodiments or elements thereof can occur or be performed simultaneously, at the same point in time, or concurrently. Unless otherwise indicated, the conjunction “or” as used herein is to be understood as inclusive (any or all of the stated options).
In accordance with some embodiments of the invention, a pool-cleaning robot may include a controller and/or a processor for executing program instructions and/or remote control instructions, which when executed by the processor or controller, carry out methods disclosed herein.
In accordance with some embodiments of the invention, a pool-cleaning robot may be configured to operate autonomously to clean a pool. A propulsion system of the pool-cleaning robot may be configured to propel the pool-cleaning robot across an internal surface of a pool, e.g., a floor of the pool or a side wall, in accordance with predetermined or programmed instructions.
In accordance with some embodiments of the invention, a pool-cleaning robot may be configured to clean a water filled pool or another type of liquid filled container (e.g. fish tank, artificial pond or other containers filled with water or other liquid). Therefore, any reference herein to a pool water or to similar or related terms should be understood as including any suitable type of liquid container (e.g., that is large enough to enable or benefit from cleaning by a pool-cleaning robot).
In accordance with some embodiments of the invention, a pool-cleaning robot may include a propulsion mechanism for propelling the robot over the traveled surface and a pumping system for pumping water and debris in the vicinity of the robot (e.g., underneath the bottom of the robot or close by) and for ensuring good contact with the pool surface, e.g., side walls or other vertically oriented surfaces The robot may be configured to have a plurality of sensors, some of which may sense tilt or orientation, such as a gyro sensor. The sensor may indicate if the robot is approaching or is on a tilt, an inclination or a vertically oriented surface. For example, the robot may use this tilt information to increase the propulsion power, which will in turn increase the force applied on the robot towards the pool surfaces, further facilitating the grip for climbing and descent of pool walls.
In accordance with some embodiments of the invention, a pool-cleaning robot may be configured to operate autonomously or partially autonomously. For example, the robot may have autonomous capabilities for mapping a floor, walls and edges of the pool. The robot may autonomously clean the pool, its edges and its substantial surrounding area. For example, the robot may generate a predetermined plan or path for traversing areas designated for cleaning. The robot may also autonomously generate amendments to a predetermined route based on real time events, for example, if the robot met an obstacle, it may reroute around it, or if a robot operator sent an instruction to the robot mid-operation, such as turning or backing away, the robot may fulfil the instruction and recalculate the route accordingly, commencing the cleaning of the pool following the newly amended route. The robot may also automate a repetitive or scheduled cleaning routine, for example the robot may be programmed to initiate a cleaning routine daily or weekly according to the user or default settings.
In accordance with some embodiments of the invention, a pool-cleaning robot may be configured to allow an operator to remotely control at least some aspects of operation of the pool-cleaning robot. In some embodiments, the pool-cleaning robot may be configured to enable at least limited remote control of propulsion of the pool-cleaning robot, e.g., during operation of the pool-cleaning robot. For example, the operator may input a command (e.g., using a designated remote control device, or using a smartphone application) to cause a change in a direction of motion of the pool-cleaning robot along a pool surface. The operator may remotely control the operation of the pool-cleaning robot when standing outside of the pool. Thus, the operator may override autonomous operation of the pool-cleaning robot, e.g., when autonomous operation does not, or cannot, address a particular situation.
In accordance with some embodiments of the invention, a pool-cleaning robot may be configured to have a visual display for displaying one or more visual indicators (e.g. mono/multi-color lights, light strips or displays) for displaying information or entertaining content. The pool-cleaning robot may be configured to display the information on all of the display strips or only on some of the strips.
A visual display, according to some embodiments of the present invention, may include one or a plurality of display surfaces, e.g., screens. Such display surfaces may include, for example, one or more display types, for example, electroluminescent (ELD) display, liquid crystal display (LCD) (for example, light-emitting diode (LED) back-lit LCD, thin-film transistor (TFT) LCD), LED display (e.g., organic light emitting diode (OLED) display, active-matrix organic light-emitting diode (AMOLED) display, plasma display, quantum dot light-emitting diode (QLED) display.
According to some embodiments of the present invention, a pool-cleaning robot may be configured to provide an indicia of various operation modes, data and status of the pool-cleaning robot or its surroundings using the visual display. For example, the visual display may display data regarding a current status or operation of the robot, or a status or operation that is about to commence, such as but not limited to direction of travel, cleaning time elapsed or cleaning time remaining, on off status and other indicative operations or status options. In some embodiments of the present invention, a pool-cleaning robot may use a visual display to provide indicia of warning or alerts presenting one or more visual indications. For example the visual display may display information regarding possible warnings of which the robot operator should be aware, e.g., that the filter system needs to be cleaned, that the cleaning cycle is about to finish, that there is a problem in the propulsion mechanism and/or in the pump, etc. In some embodiments of the present invention, a pool-cleaning robot may use a visual display to display animation or graphic figures or scenarios of various kinds aimed to inform, entertain or amuse people who view the pool-cleaning robot when in operation or otherwise, for example by displaying images, moving images, animations or videos.
In accordance with some embodiments of the invention, a pool-cleaning robot may be configured to have mono- or multi-color visual display on which the robot can controllably display information. The visual display may include one or a plurality of display surfaces or screens, for example light strips. The display surfaces may be located on an external surface of the housing of the robot, e.g., substantially on or adjacent to a top surface or side surface of the robot, so as to increase visibility of displayed indications to a viewer or operator looking at the robot from inside or outside the pool. The robot may be configured to controllably alter display parameters of the display surfaces, such as but not limited to, light intensity, color, turning on and off, blinking, phasing between adjacent or nonadjacent portions of the display surfaces, synchronous or random alterations of lighting parameters, and other parameters.
