Pool Cleaning Robot Basics What is the Right Pool Robot for Me Episode 4

What is the right pool robot for me

Driving me up the wall

We have figured out how these things vacuum and move but there are a few features that need to be understood before we can decide what is the right pool robot for me.  How a robot climbs walls and cleans the water line needs to be understood.  Because robots work in water, it is a simple thing to add floats and make them close to neutrally buoyant.  (They almost float and are pretty much weightless in water).  If you turn on the pump and suck water into the bottom, it will stick the robot onto the bottom.  The drive train can propel the robot across the pool and because it is neutrally buoyant, it can simply drive up the side of the pool as easily as it moves across the floor.  To assist with climbing the wall, most wall climbing robots have handles.  These handles are actually floats that are hinged to the top of the robot body.  Think of it like a picnic basket handle.  When the robot climbs the wall, the handle will rotate and hold up the top of the machine and keep the robot from falling over backwards on the wall.  Not all wall climbing machines have handles but the best wall climbers all have them.  The other function of the handle is to assist with scrubbing the water line.  If the handle is locked diagonally across the body of the machine, it will turn the machine when the robot climbs to the surface.

So lets follow that process.  The robot moves across the pool and the handle will stand up because it is a float and it is hinged to the top of the machine.  When the robot hits the wall, the robot will rotate and climb.  At the same time the handle will rotate and support the weight of the machine and help to prevent it from falling over backwards and pealing itself off of the wall.  When the robot hits the surface of the pool, the nose of the robot will push above the water line.  If the handle was locked straight across the body parallel with the water line, the robot would simply bob up and down at the water line.  By locking the handle diagonally across the robot (corner to corner looking down at the machine) the robot will turn as the robot breaks the surface of the water.  The float (handle) will pull the robot around so that it is on an angle to the surface of the water.  The wall scrubbing robots have rotating front and back brushes.  When the handle rotates the machine at the surface. It will bring the brush into a position where it is scrubbing the water line at an angle.  The machine will continue to try to climb the wall and this will make the machine move laterally and scrub the water line.

That took a bit of explaining didn’t it.  Anyway it is pretty clear that a real wall climbing robot needs a handle.  To scrub the water line a robot definitely need a handle.  If you are looking for a wall climber and a machine that scrubs the water line, make sure it has a handle.
