Abstract: A method of collecting excrement of pets such as dogs and cats and disposing of it in an environmentally acceptable manner, The method involves the steps of: providing a number of receptacles for excrement in a household containing pets, a park and wherever else there are pets accompanied by humans. Receptacles containing excrement are periodically collected and transported to a facility for disposal. At the facility the excrement is disposed of by flushing it into the sewer where that is legal or by composting by means of worms, larvae, micro-organisms, heat or the combination of heat, wind and rain.

Abstract: The vacuum cleaner includes a hollow canister, one end of which is closed by a removable cap to permit removal of debris from within the interior. The canister is separated into two compartments, one defined by the first end and a hollow rigid conical filter disposed in the interior. The filter has a base adjacent to the inner wall throughout its extent and tapers toward the second end of the canister. The filter further has openings too small to allow debris such as cigarette and cigar butts, excrement of animals and birds and the like to pass therethrough but large enough to allow smaller debris to pass. A second compartment is defined by the filter and a relatively flat filter having openings smaller than that of the conical filter. Both filters extend across the interior such that all air which travels through the interior must pass through the filters. An intake hose admits debris-laden air into the first compartment and an exhaust discharges air from the second compartment.
