Roof Cleaners are an item available in Plants vs. Zombies. It functions like an ordinary Lawn Mower in the front yard, except that it is used on the roof. If the player has not purchased the Roof Cleaner and a zombie gets past their defenses, it will go down their chimney and eat their brain. If a zombie makes contact with a Roof Cleaner, it will drive down the lane and run over any zombies it meets. This is true for Gargantuars (and Giga-gargantuars) as well, even though other , such as Squashes or Cherry Bombs, will only get rid of 90 points of their health. This may suggest that the Roof Cleaner, as well as the Lawn Mower and Pool Cleaner, are the strongest weapons in the game. It can be bought from Crazy Dave's Twiddydinkies for $3000.
