spinners
rotations per min. and quality of parts used.
The more roatations per min. the better the surface cleaner.
The best quality parts, last the longest.
Dont quote me but i think most spinners turn at about 2,000 RPM and landas is more like 3,500 RPM. SO IN ONE HOURS TIME YOUR CLEANING MUCH MORE SURFACE AND THERE FOR MAKES IT WORTH MUCH MORE.
Tim, where can you buy a an orig. equipment Landa water jet spinner for $400?
A water jet sell's for about $1100 there is no way in hell the body and name sells for that much over the cost of the spinner. I could be wrong but if i were someone would buy just the spinners and make a cheap rip-off of the water jet that would really clean as well.
It is just a plastic houseing and lawn mower handle.
It's all about the RPM's and few advertise what they are rated at.
