DETAILED DESCRIPTION OF THE DRAWINGS

[0007] According to an embodiment there is provided a pool related platform (PRP) that uses one of more water jets for movement and for assisting in changing the tilt angle of the PRP- for example assisting to lift the front part of the PRP or to lift the rear part of the PRP.

[0008] The PRP may be any platform that may perform an operation related to a fluid of a pool - cleaning, changing chemical composition, monitoring, and the like. Examples of a PRP include a pool cleaning robot (PCR), a pool robot that differs from a PCR, a PCR, and the like. Any example related to a PCR may be applied mutatis mutandis, to any other PRP.

[0009] According to an embodiment, the PCR is configured to output a rear upper jet 17 or a rear lower jet 14, it is also configured to output an upward jet 23.

[0010] The upward jet 23 is formed when a second impeller 21 rotates at a first rotational direction and directs filtered fluid towards a third conduit 22 that has an upward facing opening.

[0011] Either one of the rear upper jet and the rear lower jet are formed when a first impeller 11 rotates at a first rotational direction and directs filtered fluid towards a rear fluid path that includes a first conduit 12, a second conduit 13 and a rear selection unit (RCU) 30 that determines whether the fluid (a) is directed through a rear lower conduit 14 having a rear lower outlet 18, or (b) is directed through a rear upper conduit 15 having a rear upper outlet 19.

[0012] The RCU 30 includes a fluid control element (FCU) 31 that is located within the rear fluid path - and it rotated to block one of the rear lower conduit and the rear upper conduit - while directing the fluid to the other one of the rear lower conduit and the rear upper conduit.

[0013] RCU 30 also includes an FCU setting subunit 39 located outside the rear fluid path - that sets the position of the FCU.

[0014] Figures 3-11 illustrate three examples of the RCU.

[0015] According to a first example (see figure 3-6) the FCU setting sub-system 39 include a positioning element (PU) 32 and a PU interface 33 that rotates between positions thereby rotating the FCU to different positions.

a. When the FCU is moved to an upper position (blocking the rear upper conduit) it triggers a future movement of the PU interface 33 to an opposite direction.

b. When the first impeller stops rotating then the PU interface 33 (and accordingly the FCU) is moved to a first intermediate position that is slightly tilted towards the lower position.

c. When the first impeller is rotated again, the PU interface 33 (and accordingly the FCU) is moved to the lower position - and this triggers a future movement of the PU to another opposite position.

d. When the first impeller stops rotating then the PU interface 33 (and accordingly the FCU) is moved to a second intermediate position that is slightly tilted towards the upper position.

e. When the first impeller is rotated again, the PU interface 33 (and accordingly the FCU) is moved to the upper position.

[0016] Figure 5 illustrates various components of the FCU setting subunit - including axis 34, PU interface 33 that rotates about the axis and is in communication with the PU 32, spring 36, pole 38 that is supports the spring 36, RCU base element 37 movable by the spring, and RCU housing 35.

[0017] RCU base element 37 includes left recess 37-1, a left sloped facet 37-2 which is positively sloped, a center, a right sloped facet 37-3 that is negatively sloped, and a right recess 37-4.

[0018] The PU 32 has a lower left facet 32-4 which is negatively sloped, a lower right facet 32-2 which is positively sloped, a right front pin 32-1, a left front pin 32-2, and a lower tip 32-5. The PU interface 33 is rotatably coupled to the PU 32 by axis 33-1 located at the upper portion of the PU interface 33.

a. Assuming that the FCU is moved to an upper position (blocking the rear upper conduit) in this case the lower tip 32-5 of the PU 32 is caught in the left recess 37-1, which prevents the PU from rotating clockwise.

b. When the first impeller stops rotating, the lower tip 32-5 exits the left recess 37-1 and the PU rotates clockwise till the lower right facet 32-2 (of PU 32) contacts the right sloped facet 37-3 (of the RCU base element 37), and the PU interface 33 contacts the right front pin 32-1 and maintain at the first intermediate position.

c. When the first impeller is rotated again, the fluid forces the FCU axis 34 to rotate and to position the lower tip-32-5 to be caught by the right recess 37-4.

d. When the first impeller stops rotating, the lower tip 32-5 exits the right recess 37-4 and the PU rotates counterclockwise till the lower left facet 32-4 (of PU 32) contacts the left sloped facet 37-2 (of the RCU base element 37), and the PU interface 33 contacts the right front pin 32-2 and maintain at a second intermediate position.

[0019] According to a second example (see figures 7- 9) the FCU rotates about an axis and has a weight 40 near a distal end (the proximal end of the FCE is closer to the axis).

a. When the first impeller 11 rotates at a first rotational direction and directs filtered fluid towards a rear fluid path - the FCU (due to the weight) blocks the real lower conduit.

b. When the first impeller 11 rotates at a second rotational direction (opposite to the first rotational direction), fluid outside the PCR is sucked through the rear lower conduit and the rear upper conduit - and the FCU is elevated to an intermediate position - in which it does not block any of the rear conduits. The FCU is slightly elevated - for example dur to different suction of fluid through the different rear conduits.

c. Immediately following (b) - after the first impeller 11 returns to rotate at a first rotational direction, the fluid elevates the FCU to block the rear upper conduit.

[0020] According to a third example (see figures 10-11) the RCU includes a rotatable conduit extension (RCE) that rotates between an upper conduit position in which it extends the rear upper conduit 15, to a lower position in which is extends the rear lower conduit 14.

[0021] Figure 10-11 illustrates the RCE that is rotatable about an axis by a RCE setting subunit 51 that includes a RCE engine 54 and a transfer mechanism. The RCE engine and the RCE are located within a RCE housing 52. According to an embodiment the RCE is rotatable along multiple other angles not shown in figures 10-11.

[0022] The PRR may also include a drive motor and/or pump motor, electrical power means, an optional power cable, a hydraulic path may include water suction intake and outlet, filtering element in the hydraulic path, an electronic control box, sensors, a carry handle and the like.

[0023] The PCR of figure may hover over surfaces of the pool such as stairs, ledges without actually driving over said surfaces. During the hovering the pool cleaning robot may contact the surfaces by its cleaning elements and even only by its cleaning elements.

[0024] Figure 11A illustrates an example of a water jet used for movement of a PRP on a surface such as a bottom of pool. This can be used during "normal" movement of the PRP - for example over a plane of the pool that may be horizontal or have a small tilt angle (for example up to 10, 20, 30, 40, 50, 60 degrees). The water jet is outputted from the upper rear part of the PRP and is aimed downwards and backwards - for example at an angle of 235 degrees or between 190 to 260 degrees.

[0025] Figure 11B illustrates an example of a water jet used to lift the front part of the PRP - while applying pressure on the rear part of the PRP. The water jet is outputted from the upper rear part of the PRP at a first angle 91 and is aimed upwards and forwards - for example at a first angle of 45 degrees or between 20 to 80 degrees. This can be used to clean an upper facet of a stair.

[0026] Figure 11C illustrates an example of a water jet used to lift the rear part of the PRP - while applying pressure on the front part of the PRP. The water jet is outputted from the upper rear part of the PRP and is aimed at a second angle 92 - backwards and forwards - for example at a second angle of 135 degrees or between 110 to 170 degrees. This can be used to exit the pool or climb a stair.

[0027] The control of the direction of outputting the water jet can be done by a flow control unit - for example having a rotatable nozzle and one or more outlets through which the nozzle may output fluid. Other flow control units such as valve and/or switch based units may be provided.
