The automatic model is sensor controlled and has a lid which quickly opens when the trash bag gets about 10 inches and 130 degree angles from the can's sensor. With normal usage, the power will last about 6 months with 4 D-size batteries. For those that do not require trash bags, the inner bucket can be easily removed and cleaned when the trash is removed and taken out.
Many of the newer designed trash containers have hooks on their upper rims for grocery bag handles as the number of trash bags used in a week is approximately the same number of bags brought home from the grocery stores. Customers find that the 13-gallon bags at stores are cheaper than the odd sized ones and are more apt to be on sale. With the average trash emptied every night, the trash odor does not have time to accumulate in the plastic trash container.
