Pool cleaning device

A scrubber brush comprising:

• a tubular wand comprising:
• a first shaft telescopically coupled to a second shaft, the first shaft being nested within the second shaft such that the second shaft is extendable relative to the first shaft;
• an adjustment handle being slidably coupled to the first shaft and removably coupled to the second shaft, the adjustment handle sliding along the first shaft when the adjustment handle is removed from the second shaft, the adjustment handle being configured to secure a position of the first shaft relative to the second shaft when the adjustment handle is coupled to the second shaft;
• a retaining flange being integrally coupled to the second shaft adjacent to the first shaft, the first shaft being nested within the second shaft adjacent to the retaining flange, the retaining flange being resiliently compressible beneath the adjustment handle, wherein the adjustment handle compresses the retaining flange, thereby squeezing the retaining flange over the first shaft, and thereby restricting movement of the first shaft relative to the second shaft;
• the adjustment handle including a handle threading and the retaining flange including a flange threading, the handle threading being complementary to the flange threading such that the adjustment handle is threadably coupled to the second shaft, wherein rotation of the adjustment handle over the second shaft is configured to compress the retaining flange, thereby bracing the first shaft within the second shaft and securing a length of the tubular wand;
• a battery housing being affixed to the second shaft, the battery housing having an interior battery space, the battery housing being configured to inhibit penetration of water into the interior battery space;
• a power source being positioned in the interior battery space, the power source being a rechargeable battery;
• a charging port being positioned on the battery housing, the charging port being electronically coupled to the power source;
• a handle being affixed to the second shaft, the handle being adjacent to the battery housing, the handle being spaced from the adjustment handle;
• a motor housing being pivotably attached to the first shaft, the motor housing having a first side and a second side, the motor housing being movable between an upwardly angled position and a downwardly angled position, wherein the second side is positioned facing toward the tubular wand when the motor housing is in the upwardly angled position, and wherein the second side is positioned facing away from the tubular wand when the motor housing is in the downwardly angled position, the motor housing having an interior motor space, the motor housing being configured to inhibit penetration of water into the interior motor space;
• a motor being positioned in the interior motor space, the motor being electronically coupled to the power source, the motor being a rotation motor;
• an output shaft being rotatably coupled to the motor, the output shaft extending outwardly from the motor, the output shaft being positioned in the first side of the motor housing;
• a bristle brush being removably coupled to the motor housing, the bristle brush having a front side and a back side, the back side being removably attached to the output shaft, wherein the motor rotates the output shaft, thereby rotating the bristle brush, and wherein pivoting the motor housing pivots the bristle brush between the upwardly angled position and the downwardly angled position;
• a plurality of bristles being positioned on the front side;
• a power switch being positioned on the battery housing, the power switch being actuatable to turn the motor on and off;
• a coupler releasably securing the bristle brush to the motor housing, the coupler comprising:
• a motor coupling fin being positioned on the output shaft;
• a brush coupling fin being positioned on the back side, the brush coupling fin being complementary to the motor coupling fin such that engagement of the motor coupling fin to the brush coupling fin secures the bristle brush to the motor;
• a release tab being mounted to the motor housing, the release tab being positioned proximate to the motor coupling fin, the release tab releasably securing the motor coupling fin to the brush coupling fin, the release tab comprising:
• a pull tab extending upwardly from the motor housing, the pull tab being positioned above the output shaft;
• a pressure plate being mounted within the motor housing adjacent to the motor coupling fin, the pressure plate being configured to apply a pressure downwardly on the motor coupling fin and the brush coupling fin when the bristle brush is secured to the motor housing, thereby securely engaging the motor coupling fin with the brush coupling fin;
• and
• a spring being mounted to the motor housing, the spring being tensioned to exert the pressure on the pressure plate such that the motor coupling fin retains physical contact with the brush coupling fin.
