Making it more easily cleanable would be straightforward but not a
selling point. "You Mk3 Bogpump can easily be dismantled for monthly
cleaning" isn't going to sell any units.

That's basically what the competing Sanisplit units compete on. The
macerator part detaches from the main unit with seals to reduce spillage. It
takes about 10 seconds to remove, with no pipes to disconnect. You can then
clean it yourself, or they offer an exchange service at a very reasonable
price. The pump is also much stronger. They allow much longer and more
flexible runs.
