I know they make them. I am just looking for some one that sells them. Any ideas? Thanks
They have advantages. On a regular surface cleaner, they use the pressure of the water to propel the tips through the rotation. That means that they lose some of their effectiveness. Think of a glancing blow. Sure you feel it, but it is not as bad as it could have been. With the motor driven surface cleaners, they are able to maintain a constant speed, and are able to either point the tips straight down, or you can actually angle the tips so that it cuts at the concrete. That would make it a lot more effective.
The downsides, you better have your wash rig set up for them. And, if you are going to call american cleaner for info, plan on spending some time on the phone to get the information that you want.
Definitely Chris, ever heard your non-motorized surface spinner bar slow down over that puddle of water that just would not move out the way .
It is also an advantage of a vacuum recovery non-motorized surface cleaner you also would not have the reduced rpm, no puddle/pooling to deal with (Scott loves his).
The motorized spinner affords you the ability to walk forward faster (2200 rpm non-motorized vs 3400 standard motorized, (SPECIAL JIMBERIZED SPEC 4000 RPM ) the spray pattern would cover the same circumference faster.
This is one reason high flow machines that use 3 & 4 bar spinners are so fast (provided they are all the same circumference surface cleaners).
To complete a full circumference of cleaning action a :
2 bar spinner has to spin 180 degrees of rotation
3 bar spinner has to spin 120 degrees
4 bar spinner has to spin 90 degrees
The motorized spinner imparts all of the energy of the water stream toward the surface being cleaned (provided the nozzles are perpendicular to the surface to be cleaned) instead of some being transformed into kinetic energy to spin the bar (thrust). Some argue it does not require a lot of energy to impart the rotational energy, but if you place the nozzles directly downward on a non-motorized ABS plastic spinner you may be surprised how much more lift you get on the surface cleaner.(it would not clean, because spinner bar should not rotate if balanced 100%)
Premium swivels have less resistance to rotation, thus slightly less energy transformation required, thus and more importantly higher attainable rpms with all other parameters being constant.
.. I think it wise to make clear that 'faster' in this case should only address the higher efficiency in spreading the power. The total power involved that is being spread though still dictates how fast the unit can be moved. Also, the kinetic recoil or thrust is still present or aka-still happens/escapes regardless how angled the tips are placed. The direction of that recoil/thrust is just pointed in a different direction and absorbed or utilized diferently. In case of straight down it puts pressure on the union and surfacer as a whole. This is confirmed by the lift you mention...This is one reason high flow machines that use 3 & 4 bar spinners are so fast (provided they are all the same circumference surface cleaners)
