|Special Effect||"+25% critical and headshot damage"|
The Cleaner is the custom version of the UMP 45. It has good damage for an SMG, but below average Rate of Fire. This is negated by its high accuracy and clip of 30 rounds.
Use the Cleaner for mid-to-long range combat. It will not be effective at close ranges due to low RoF. Use it for secondary with most of Machine Guns to have something accurate and for mid-to-long range fighting in case you run out of ammo. One of the best attachments for this weapon are Laser Sight, which increases the chance of doing a critical hit, a much-needed enhancement to a weapon that deals more crit damage. Another good attachment is Hair Trigger, increasing fire rate.
