The clutch/pulley is quite expensive for what it is, for example.
Neptune TLs are interesting machines. The TOL model FAV9800 is more rare, has onboard water heating and the same LCD control panel as the Neptune FL MAH7500.
However, they do not perform very well on certain kinds of loads -- small loads and lightweight fabrics, even a set of sheets. I recently ran a load of SEVENTEEN typical cotton and synthetic blend short-sleeve button-down shirts and a few other items. I figured surely that'd be a large enough load to tumble properly ... but it did not. The bundle of items simply sat there between the tumblers, wiggling a little. The items on bottom got a drubbing, the pieces toward the top got nothing. The shirt on top had a small dry spot as well. I watched for the entire medium soil level wash period and the load never flipped over even once, so I reset it for another wash and helped the load roll throughout the wash and rinses. The dry shirt would have been fully wet by end of the cycle after spin-sprays and rinses, but several of the items would not have gotten a good/proper washing with detergent.
A load of heavy items (towels, jeans) or mixed lightweight and heavy items tumbles quite nicely, though.
