Sanitation Expert is the Rare toxic variant of the Engineer in Plants vs. Zombies: Garden Warfare and Plants vs. Zombies: Garden Warfare 2. He has a toxic aura which damages nearby enemies, and his attack inflicts toxic damage overtime too. However, in Plants vs. Zombies: Garden Warfare 2, he does not have any toxic aura, and can only inflict toxic damage with his primary weapon. He was released in the Legends of the Lawn DLC.


Stickerbook description

All-out war with the Plants is messy business. Thankfully, the Sanitation Expert is here to clean that mess up. It may not be glamorous (we don't pay him), but nothing beats a hard day's work and a job well done. Thanks Sanitation Expert!

Primary weapon

His primary weapon is the Toxic Trash. It deals 35 (40 when upgraded) impact and critical damage and 18 splash damage in addition to continuous toxic damage to plants.


Sonic Grenade

The Sonic Grenade is a grenade that, when thrown, will stun plants in a small radius for a short time and forces Burrowing Chompers out from the ground.

Proximity Sonic Mine

An alternate ability of the Sonic Grenade, the Proximity Sonic Mine is a landmine which can stun plants for about five seconds when they come close to it. It makes Chompers come out of their Burrow ability if they are using it. This can be very useful for defending a teleporter or trying to escape from plants.


The Jackhammer allows for quicker movement but at the cost at not being able to use your other abilities, though you can still fire your primary weapon, and if you bump into a plant, the plant will suffer knockback and light damage.

Turbo Jackhammer

An alternate ability of the Jackhammer, the Turbo Jackhammer functions the same as the Jackhammer except that it travels faster, but lasts for a shorter amount of time.

Zombot Drone - GW1 Only

The Zombot Drone is a drone equipped with the Zombot Laser and the deadly Cone Strike. It has five health.

Rocket Drone - GW1 Only

The Rocket Drone is an alternate version of Zombot Drone having more health (20). It is equipped with the Mean Beam and Lone Cone.

Big Bolt Blaster - GW2 Only

The Big Bolt Blaster is a mounted turret similar to the Pea Gatling. It has 100 ammo and a very high rate of fire.

Bedazzled Bolt Blaster - GW2 Only

The Bedazzled Bolt Blaster is a reskin of the Big Bolt Blaster and therefore has no difference other than appearance and having different crosshairs.

As long as you are within range of your opponent(s), You will continually be doing damage thanks to the Sanitation Expert's toxic aura.

Balance changes

May 2018 Patch

  • Increased the Toxic Trash's splash damage from 15 - 18
  • Increased the Toxic Trash's projectile speed



  • In Plants vs. Zombies: Garden Warfare, he had the second highest critical damage at 40, only being beaten by the Painter at 48.
  • He was the last toxic character to be added and the only one to be added in DLC content. However, this only applies to Plants vs. Zombies: Garden Warfare.
  • He is the only Engineer variant with two words in his name.
  • Similarly to most of the other Engineers, his facial hair appears to have been removed in Plants vs. Zombies: Garden Warfare 2.
  • He is the only toxic zombie variant to not have with a toxic aura but only in Plants vs. Zombies: Garden Warfare 2.
  • In the zombie mission "You Are Cordially Invited...", there is a Sanitation Expert named Barth (a pun on the word "barf") who will help the player find the location of Dr. Zomboss' secret lair if they beat his time at shooting gnome targets. However, once the player has done this, Barth is about to tell the location of the lair, but gets distracted by a Potato Mine next to him. He looks at the Potato Mine, looks at the player (with a worried expression) and is then launched over a hedge by the Potato Mine. However, even if the player doesn't beat his time, he says "You no beat Barth's time. But I will still show you anyways!"
    • If the Potato Mine is destroyed before the quest is complete, then he will still look at the location of where the Potato Mine was as the player still hears chittering sounds, even though it was destroyed, and then he will still fly up into the air while groaning.
  • His name is very much the opposite of what he really is, as he is the Sanitation Expert, yet he doesn't look very sanitised himself.
    • His upgrades further prove this.
