Kenwood Steam mop

The Manufacturer suggests you clean the hose by removing the water tank dammed if u can get it off though.

There are also bristle brushes (usually yellow brushes with white bristles) attached to handles which help scrub grout lines. If there are areas that are especially dirty or have build-up on them, you can use a stiff nylon wire brush or fine wire brisle brush to spot scrub areas. Make sure not to continuously scrub in one spot with those type of brushes because they have the tendensy to remove grout quicky causing a recessed dip in the grout.
In the event you get the floor and grout clean, I would suggest the first thing you do next is find a high quality ceramic floor tile and grout sealer. If the floor is in an area that does not have excessive moisture you will find the floor is extremely easy to keep clean.
The main problem with sealers is if the floor has the possibility of getting and remaining wet, the floor becomes slippery. ( Such as a tiled entry or bathroom )
Good luck and I hope this helped.

To clean tiles & particularly the grout you need what commercial cleaners call a "doodle bug", basically it's a giant scourer pad on a mop handle. They come in different grades of scourer, depending on the floor surface. Cleaners also masking tape steel wool or scourers onto the toe of their shoe to use to remove tough grime.
