I think what you're talking about is a just a basic side discharge
mower. By not cutting up the grass finely, they leave the clippings on
the lawn surface, where it's highly visible, especially after it start
to dry out. Good solution for a field or similar area where you
don't really care, but a poor choice for a front lawn.

Fwiw, my Stiga Compact ride-on mulcher doesn't leave clumps behind
until or unless there's a build-up of wet clippings on the tyres which
eventually falls off. These are easy to pick up by hand or they can be
re-mulched by the mower.

A remote controlled hover mulcher might be the answer.
