These adjectives mean marked by an absence of due or proper care or attention. Sloppy evokes the idea of careless spilling, spotting, or splashing; it suggests slackness, untidiness, or diffuseness: a sloppy kitchen; sloppy dress. "I do not see how the sloppiest reasoner can evade that" (H.G. Wells).
Slovenly implies habitual negligence and a lack of system or thoroughness: a slovenly appearance; slovenly inaccuracies. Unkempt stresses dishevelment resulting from a neglectful lack of proper maintenance: "an unwashed brow, an unkempt head of hair" (Sir Walter Scott).
Slipshod suggests inattention to detail and a general absence of meticulousness: "the new owners' camp ... a slipshod and slovenly affair, tent half stretched, dishes unwashed" (Jack London).
