No cleaning needed here..

The Cleaner is one of these sprawling action/adventure/platform games which always seem to impress, because they always seem to have great graphics, fluid music, a great concept and a storyline in which to tell it to the player. The Cleaner fits comfortably into all of those merits and does so with incredible style.
Visually it excels, creating a believable world full of different creatures, and few games can match the concept in terms of pure epic. The storyline, as impressive and well drawn as it is, is almost entirely told in the opening moments, leaving us as the player with nothing to think about whilst we play, leaving the play slightly emptier than it would be had we been allowed to work even the tiniest details.

But its a pretty weak critiscism and probably won't get in the way of your enjoyment.. it didn't get in the way of mine.
