Robert Smith said it took years to develop. The invention installs the same as a standard toilet, but it has an odor removal system in the back.
To use toilet, lift the handle first to activate the fan. The odor will be sucked out through several holes in the bowl, and the fan shuts off when you flush.
One of Smith's first customers said he was pretty skeptical at first.
"We tried it. No one wanted to be the first to admit it. But the feedback was good -- that it was doing its job," said customer Phil Nichols.
Businesses aren't the only ones using the odorless toilet. They're being used in homes now too, but the bad news is right now, you can only buy it from the inventor.
