Robotic pool cleaner with extended brush assembly
A self-propelled robotic pool cleaner includes a housing with a lower portion having an inlet and an upper portion having an outlet, the lower and upper portions define an internal chamber therebetween. A filter and a water pump are mounted in the internal chamber for suctioning pool water into the inlet and discharging filtered water through said outlet. Rotationally-mounted elements are mounted to the housing for supporting and guiding said cleaner on a surface of the pool. An arm assembly extends outward from said housing, and a rotary brush assembly is mounted at a distal end of the arm assembly. An electric motor is coupled to at least one of said water pump, the rotationally-mounted elements and the rotary brush. The pool cleaner is configured to continue climbing upward on a pool wall and tell the rotary brush assembly is above the water level and climbs over the pool coping edge propelling said pool cleaner onto the pool deck.
1. A self-propelled swimming pool cleaner comprising:
a. a housing (i) defining a central axis, (ii) comprising at least one intake port and at least one exhaust aperture, and (iii) comprising a first end and a second end opposite the first end;
b. a brush support extending forward of the housing when the housing is travelling in a forward direction;
c. a brush (i) connected to the brush support and (ii) configured to rotate about a rotary axis parallel to, and spaced from, the central axis;
d. a filter;
e. a pump configured to draw water from a swimming pool through the at least one intake port and the filter for exhaustion through the at least one exhaust aperture into the swimming pool, wherein the filter and the pump are within an internal chamber of the housing; and
f. wherein the self-propelled swimming pool cleaner consists of two wheels, wherein a first wheel of the two wheels is supported at the first end of the housing and a second wheel of the two wheels is supported at the second end of the housing.
2. A self-propelled swimming pool cleaner comprising:
a. a generally cylindrical housing (i) defining a central axis and (ii) comprising at least one intake port, wherein the generally cylindrical housing defines an internal chamber, wherein a pump and a motor are contained within the internal chamber of the generally cylindrical housing, wherein the pump is configured to draw water from a swimming pool through the at least one intake port, and wherein the generally cylindrical housing comprises a width defined in a direction parallel to the central axis that is greater than a front-to-back length of the generally cylindrical housing defined in a direction perpendicular to the central axis;
b. a brush support extending forward of the generally cylindrical housing when the generally cylindrical housing is travelling in a forward direction;
c. a brush (i) connected to the brush support and (ii) configured to rotate about a rotary axis parallel to, and spaced from, the central axis; and
d. wherein the self-propelled swimming pool cleaner consists of two wheels, wherein a first wheel of the two wheels is at a first end of the housing and a second wheel of the two wheels is at a second end of the housing.
3. A cleaner according to claim 2 in which the brush support comprises an arm configured to pivot relative to the housing.
4. A cleaner according to claim 2 in which the brush comprises fins extending parallel to the rotary axis.
5. A cleaner according to claim 2 further comprising a filter positioned at least partially in the housing in use, at wherein the pump is configured to draw water from a swimming pool through the at least one intake port and the filter.
6. A cleaner according to claim 2 , wherein the brush and brush support define a brush assembly comprising a brush assembly width in a direction transverse to the forward direction, wherein the brush assembly width is greater than a width of the generally cylindrical housing in the direction transverse to the forward direction.
7. A cleaner according to claim 2 , wherein the brush is deflectable relative to the housing and the cleaner is configured to transition from a horizontal surface to a vertical surface and to climb the vertical surface during cleaning.
