2. A vacuum cleaner according to Claim 1, including clip means embedded in said body, said baffle being resiliently detachably engaged by said clip means for removably securing said baffle in said body.

3. A vacuum cleaner according to Claim 1, wherein said filter has an open end adjacent said housing and a closed end adjacent said baffle.

4. A vacuum cleaner according to Claim 1, wherein said filter has an open end adjacent said housing and a closed end adjacent said baffle, said filter having an outer truncated conical configuration, said closed end being provided with a relatively deep circular recess therein and with an inner truncated conical projection extending towards said closed end concentrically disposed with respect to said outer truncated conical configuration to define an optimum filter surface area while trapping solid material not completely removed by said centrifugal separation.

5. A vacuum cleaner comprising a tubular fiberglass body open at both ends thereof, a turbine and motor housing detachably secured to one of said ends, a motor and turbine in said housing for inducing suction through said body, said housing having an exhaust outlet therein between said turbine and said motor, an air intake conduit connected to said body and spaced from said ends, a removable basket and filter detachably secured between said housing and body and extending into said body entirely below said filter, and an arcuate dish-shaped fiberglass baffle disposed in said body between said filter and said intake conduit, said baffle having a central opening therein, a fiberglass container detachably secured to the other of said ends, said baffle having a portion in the shape of a hyperboloid of revolution for deflecting dirt containing intake air into said container for centrifugal separation before passing through said central opening and through said filter and out of said exhaust outlet, clip means embedded in said body, said baffle being resiliently detachably engaged by said clip means for removably securing said baffle in said body, said filter having an open end adjacent said housing and a closed end adjacent said baffle.

6. A vacuum cleaner comprising a tubular fiberglass body open at both ends thereof, a turbine and motor housing detachably secured to one of said ends, a motor and turbine in said housing for inducing suction through said body, said housing having an exhaust outlet therein between said turbine and said motor, an air intake conduit connected to said body and spaced from said ends, a removable basket and filter detachably secured between said housing and body and extending into said body entirely below said filter, and an arcuate dish-shaped fiberglass baffle disposed in said body between said filter and said intake conduit, said baffle having a central opening therein, a fiberglass container detachably secured to the other of said ends, said baffle having a portion in the shape of a hyperboloid of revolution for deflecting dirt containing intake air into said container for centrifugal separation before passing through said central opening and through said filter and out of said exhaust outlet, said body, said baffle, and said container being formed of fiberglass, clip means arranged peripherally on the interior of said body, engaging means on said baffle, said baffle being resiliently detachably engaged by said clip means for removably securing said baffle in said body, said filter having an open end adjacent said housing and a closed end adjacent said baffle, said filter having an outer truncated conical configuration, said closed end being provided with a circular recess therein and with an inner truncated conical projection extending towards said closed end concentrically disposed with respect to said outer truncated conical configuration to define an optimum filter surface area while trapping solid material not completely removed by centrifugal separation.

7. A vacuum cleaner according to Claim 6, wherein said recess and said projection are in alignment with said central opening, the upper surface of said baffle being shaped to direct solid matter falling from said filter through said central opening and to said container.

8. A vacuum cleaner comprising a tubular fiberglass body open at both ends thereof, a turbine and motor housing detachably secured to one of said ends, a motor and turbine in said housing for inducing suction through said body, said housing having an exhaust outlet therein between said turbine and said motor, an air intake conduit connected to said body and spaced from said ends, a removable basket and filter detachably secured between said housing and body and extending into said body entirely below said filter, and an arcuate dish-shaped fiberglass baffle disposed in said body between said filter and said intake conduit, said baffle having a central opening therein, a fiberglass container detachably secured to the other of said ends, said filter having an open end adjacent said housing and a closed end adjacent said baffle, said closed end being provided with a circular recess therein and with an inner projection extending towards said closed end to define an optimum filter surface area.

9. A vacuum cleaner comprising a tubular fiberglass body open at both ends thereof, a turbine and motor housing detachably secured to one of said ends, a motor and turbine in said housing for inducing suction through said body, said housing having an exhaust outlet therein between said turbine and said motor, an air intake conduit connected to said body and spaced from said ends, a removable basket and filter detachably secured between said housing and body and extending into said body entirely below said filter, and an arcuate dish-shaped fiberglass baffle disposed in said body between said filter and said intake conduit, said baffle having a central opening therein, a fiberglass container detachably secured to the other of said ends, said filter having an open end adjacent said housing and a closed end adjacent said baffle, said closed end being provided with a circular recess therein and with an inner projection extending towards said closed end to define an optimum filter surface area, said recess and said projection being in alignment with said central opening.

10. A vacuum cleaner comprising a tubular fiberglass body open at both ends thereof, a turbine and motor housing detachably secured to one of said ends, a motor and turbine in said housing for inducing suction through said body, said housing having an exhaust outlet therein between said turbine and said motor, an air intake conduit connected to said body and spaced from said ends, a removable basket and filter detachably secured between said housing and body and extending into said body entirely below said filter, and an arcuate dish-shaped fiberglass baffle disposed in said body between said filter and said intake conduit, said baffle having a central opening therein, a fiberglass container detachably secured to the other of said ends, said filter having an open end adjacent said housing and a closed end adjacent said baffle, said closed end being provided with a circular recess therein and with an inner projection extending towards said closed end to define an optimum filter surface area, said body, said baffle, and said container being formed of fiberglass, said recess and said projection being in alignment with said central opening, the upper surface of said baffle being shaped to direct solid matter falling from said filter through said central opening and into said container.
