Generally, Reef Blowers are used to clean yards similar to real life leaf blowers and shop vacuum cleaners. It uses a long brown or black hose with a red suction head that has a switch on it to change between its blow and suction functions. It is connected to a dust bag which is white, has a red top, has a filter, a cartridge filter, and attachments. The size of the dust bag varies and generally has incredible storing space and elasticity, able to vacuum up things much larger than the bag itself ranging from the windows and nose of Squidward's house to the entire ocean. The suction and blowing force from the machine ranges from mild breezes to being able to fire large projectiles that can easily destroy a stone house.
While it is designed to be used for yard work, SpongeBob and Patrick have used it for more recreational uses like reef blower tag while Squidward used it for pranking purposes. So far, most squid folk look down upon using reef blowers in a childish manner, though Squidward became an exception. It was able to vacuum the pineapple lines off of SpongeBob's house with no visible damage to it and the door off of Squidward's house, comically leaving no hole Squidward to exit his house from where the door was. Other strange feats of the reef blower include the inflation an unsuspecting squid's head, removing the eyes and noses off of two squid's faces then putting two sets of eyes on one squid and two noses on the other without any other visible harm on them, and propelling Squidward several hundred feet into the sky.
The only people seen using the reef blower is SpongeBob, Patrick, Squidward, and the Groundskeeper of Tentacle Acres.
So far there are 2 versions of the reef blower.
Version 1 of the Reef Blower is very large (about 1 1/2 times the size of SpongeBob) and appears to be difficult to use. It breaks down often but has incredible suction power, able to completely drain the ocean before exploding. The device also has an extremely long pull cord which allows SpongeBob to draw it across long distances. This version was seen in "Reef Blower" and The SpongeBob Movie: Sponge Out of Water.
Version 2 of the Reef Blower is smaller and more compact (about the size of a small backpack). The holding compartment is able to hold the nose of Squidward's house. This version was seen in "Squidville."
