We apologize for the delay in responding; due to a technical issue a reply was not posted. But for those who may be considering this product, the response is that we do not have an older model of this attachment. The model 8222 Crevice Cleaner is the only model manufactured.
Due to a technical issue a response to this question may not have posted so we are responding now. The Crevice Cleaner Attachment is compatible only with Mantis 7000 series tillers.
