If your Nilfisk-ALTO Floor Machine isn't vacuuming dirty water effectively, several issues could be the cause: * The recovery water tank might be full, in which case you should empty it. * The vacuum grid could be clogged, so clean it. * The vacuum hose might be disconnected or damaged; connect or replace it as necessary. * The squeegees could be dirty or worn; clean or replace them. * The gasket of the transparent cover might be damaged; inspect and clean the seating surface or replace the gasket. * The vacuum system motor could be faulty and requires replacement.
