| I did not have the tilt sensor(tm1 module) the first year. We have all terraces and I noticed a lot of jumping around going over terraces. Ordered the tm1 the second year and felt it really helped, around $500. The dealer recommended it at first but I did not want to spend the money. Did get Accuboom and that is the best money spent. The auto shutoffs help save on chemical and there is less stress trying to turn the 5 sections of boom on and off all the time. | |
