My friend swears by the Karcher wet and dry vacuum for sticky messes, especially with young kids around. It's not the cheapest upfront but honestly it saves you from having to sweep and mop separately, so works out practical in the long run. The smaller models are pretty manageable too if you don't want something taking up half your storeroom, and the suction is strong enough to handle bits of rice and biscuit crumbs without drama.
