Most of the bidet seats are fairly similar in cleaning.
After use, the wand retracts under a stream of water.
They are self cleaning.
80% of homes in Japan have these.
The best color match to the Toto Cotton White will be a Toto washlet.
The models with the wireless remote start with the E200, and then the S300
Any brand of elongated bidet seat or washlet will drop right onto the Gwyneth or Ultramax II.
Any bidet seat with remote, will also have air dry.
Not all have the deodorizers.
I do sell a lot of the Biobidet 1000 with remote.
