“Wrap around” design for using magnetic sweepers in grass
At Bluestreak we design our “all terrain” magnetic sweepers with a “Wrap around” feature.
The “Wrap Around” feature specifically deals with the problem of “wipe off” that occurs when using magnetic sweepers on grass or weeds.
With the “Wrap Around” feature the debris that is picked up gets pushed backward on the sweeper and then it simply snaps around onto the back of the sweeper without falling off or being wiped off by grass.
The problem of “Wipe off” occurs when grass or weeds brush the bottom of the sweeper and the debris that is attached to it is pushed backward on the bottom of the sweeper.
If the debris gets pushed to far back and out out of the magnetic field of the magnet, the nails or debris you picked up can fall off. This can happen with many magnetic sweepers that have a magnet inside the housing where the magnet does not fill the entire housing.
