A leaves collection system for use with a portable blower/vacuum in the vacuum mode with a lid allowing the rejection of debris in a plastic or paper bag. The lid (of round shape with a lateral groove) has three main openings, one for the entrance of debris and two for the outlet of air as well as holes to attach the various elements to the lid with cable ties. The lid is inserted into the opening of the bag and the bag is held in place on the lateral edge of the lid by a bungee cord in the groove. Ribbed pipe connects the fan outlet of the blower/vacuum to the lid and sends debris towards the lid and the bag. A membrane under the bag protects the bag from the roughness of the ground.

1. A debris collection system for use with a portable blower/vacuum with a fan outlet through which the debris is ejected when the blower/vacuum is used in the vacuum mode, comprising: a lid of round shape with a flat or domed top that has a first opening to allow for the entrance of debris, a second and a third opening for the air outlet, holes to attach a first and a second mesh strainer, a first and a second 45 degree elbow and a ribbed pipe coupling to the lid with cable ties and on the lateral side a 360 degree groove in a U shape with a flat bottom, parallel walls inclined toward the lid top as well as an anti-skid tape at the bottom of the groove in the U shape; a semi-flexible ribbed connecting pipe for connecting the fan outlet of the blower/vacuum in vacuum mode to the first opening of the lid; a ribbed pipe coupling to bind the ribbed connecting pipe to the lid; a flexible Poly Tubing coupling sleeve to connect the fan outlet of the blower/vacuum to the ribbed connecting pipe; a protective membrane under a debris collection bag; and a collection bag made of plastic, paper, fabric, or other material which goes over the opening by placing the bag opening around the lid. 2. The debris collection system of claim 1, wherein the lid of round shape with a flat or domed top has the first opening to allow for the entrance of debris near the edge of the lid. 3. The debris collection system of claim 2, wherein the lid of round shape with a flat or domed top has in the first opening to allow for the entrance of debris, the first 45 degree elbow of which one end is female and the other male. 4. The debris collection system of claim 3, wherein a shoulder of the female part of the first 45 degree elbow is on the outside of the lid relative to the debris collection bag and the male end is on the inside of the lid, which connects with the bag. 5. The debris collection system of claim 4, wherein the male end of the first 45 degree elbow on the inside is inserted into the female end of the second 45 degree elbow so as to form a 90 degree angle when they are one inside the other. 6. The debris collection system of claim 5, wherein the output of the male part of the second 45 degree elbow is directed towards the center of the lid. 7. The debris collection system of claim 6, wherein the male part of the second 45 degree elbow is attached to the lid by putting a cable tie through two holes on the top of the lid and the hole in the wall of the male part of the 45 degree elbow on the inside of the lid. 8. The debris collection system of claim 7, wherein one of the holes on the top of the lid coincides with the hole in the male part of the second 45 degree elbow and the other with the end of the male part of the elbow. 9. The debris collection system of claim 5, wherein a hole is made in the wall of the male part of the second 45 degree elbow located near the inside of the lid. 10. The debris collection system of claim 1, wherein the lid of round shape with a flat or domed top has the second and the third opening to let out air, each one covered on the inside of the lid by a round strainer of domed shape with at least two ears arranged on the rigid contour of the strainer. 11. The debris collection system of claim 10, wherein the ears are spaced out one from the other around the rigid circle of each strainer, but the space can vary between ears. 12. The debris collection system of claim 10, wherein the rigid side of the strainer with the ears on the inside of the lid and the domed part directed away from the inside of the lid, towards the debris collection bag. 13. The debris collection system of claim 10, wherein the strainers are attached to the lid by ears with cable ties that pass through small holes in the lid located near the rigid outer contour of the strainer and on each side of the ears placed on the rigid contour of the strainer. 14. The debris collection system of claim 13, wherein the small holes made in the lid on each side of the ears are equidistant from the center of each of the strainers. 15. The debris collection system of claim 1, wherein the lid of round shape with a flat or domed top has on the lateral contour the 360 degree groove in a U shape of which the bottom is flat and the walls of which are parallel and inclined toward the top of the lid. 16. The debris collection system of claim 15, wherein the anti-skid tape is glued to the bottom of the groove. 17. The debris collection system of claim 1, wherein the lid of round shape with a flat or domed top has an extension of the lateral contour on the opposite side of the first opening allowing for the entrance of debris. 18. The debris collection system of claim 1, wherein the fan outlet of the blower/vacuum is inserted into the semi-flexible ribbed connecting pipe and is held in place by the flexible Poly Tubing coupling sleeve made of a plastic tube covering both a part of the fan outlet and the ribbed connecting pipe. 19. The debris collection system of claim 18, wherein the fan outlet and the ribbed connecting pipe are held together by two cable ties placed transversely to the pipe and near both ends of the Poly Tubing coupling sleeve. 20. The debris collection system of claim 1, wherein the two openings on the surface of the lid for the air outlet have two 45 degree elbows of which one end is inserted into the outlet opening and the other end is oriented towards the ground. 21. The debris collection system of claim 20, wherein a 45 degree elbow is built with a female part of which the length is smaller than the male part and of which the diameter of the female part is taller than the male part. 22. The debris collection system of claim 20, wherein a 45 degree elbow is built with a male part which the length and the diameter are smaller than the female part. 23. The debris collection system of claim 22, wherein the 45 degree elbow has a swelling between the male and the female part and two holes opposed to one another in the wall of the male part. 24. The debris collection system of claim 1, wherein the two openings on the top of the lid for the air outlet have two pieces of ribbed pipe split perpendicularly to the extrusions, of which one end is inserted into the outlet opening and the other end is oriented perpendicularly to the outside surface of the lid. 25. The debris collection system of claim 1, wherein the collection bag made of plastic, paper, fabric or other material of which opening is placed around the lateral side of the lid of round shape with a flat or domed top over which a bungee cord is placed over top of the wall of the debris collection bag in the groove on the lateral side of the lid. 26. The debris collection system of claim 1, wherein a plastic membrane or other material is placed under the debris collection bag to protect the bag from the roughness of the ground, and of which the front part of the membrane has an opening in its center near the edge allowing one to insert it around the base of the ribbed pipe coupling connecting the ribbed connecting pipe to the lid. 27. The debris collection system of claim 1, wherein the lid of round shape with the flat or domed top has on the lateral side the 360 degree groove in a V shape. 28. The debris collection system of claim 1, wherein a T-shaped handle is on the top of the lid and whose center of the handle coincides with the center of the lid.
