A device for automatically collecting loose pet hair, debris and allergens from a pet as the pet enters or leaves the device where the pet is fed, thus keeping the pet owner's house cleaner. The device is a container consisting of three interconnected compartments. Loose particles are removed from the pet by air suction as the pet passes through collector plate assemblies in the first compartment to reach its food in the second compartment. A fan that induces the air suction in the first compartment and the filter that removes the hair from the air stream are both located in the third compartment. A sensor in the second compartment signals a receiver associated with the fan to turn the fan on and off based on the presence of an animal within the device. An optional second exit with a one way door can be provided in the second compartment.
