The Bock extractor that I have is the smallest size that they made. It does need to be bolted down, but only needs a standard 120 volt outlet. I just drain mine into a bucket as I like to see how much water comes out. I have seen other extractors for sale but they were always larger models that require 230 volts. I would check with companys who sell or service commercial washers, maybe you will get luckey and find one. The Spin-X is neat but very small. Jeff
