Abstract
Abstract A cleaning apparatus having a pan-shaped housing carrying burshes engageable with a surface to be cleaned. Mounted on the top of the housing is a spinner assembly having a body containing a longitudinal passage. A tubular shaft rotatably mounted in the passage carries tubular arms located within the housing. The fluid flows from the hollow shaft into the arms and is discharged through the slots in the nozzles. Nozzles having slit orifices are mounted on the ends of the arms. The shaft has a head located in a chamber at one end of the passage. The diameter of the head is larger than the diameter of the passage and is dynamically balanced by the flow of fluid under pressure through the passage and chamber into the hollow shaft.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
183 words
An apparatuS for discharging fluid under pressure comprising: a body having a passage extended into said body and chamber, one portion of said passage open to said chamber; shaft means located in said passage and rotatably mounted on said body, said shaft means having a head located in said chamber and a longitudinal passage open to the chamber, said head having a transverse dimension larger than the transverse size of the passage in the body whereby the head limits axial movement of the shaft means relative to the body; means for carrying fluid under pressure to the passage in the body whereby fluid flows from said passage in the body into the chamber and around the head and into the passage in the shaft means, said fluid subjecting the head to opposite longitudinal forces to substantially longitudinally balance the shaft means in the body, and fluid discharging means mounted on the shaft means to receive fluid from the longitudinal passage in the shaft means, said fluid discharging means being operable to rotate the shaft means in response to the discharge of fluid therefrom.
Claim 2
Independent Claim
183 words
An apparatuS for discharging fluid under pressure comprising: a body having a passage extended into said body and chamber, one portion of said passage open to said chamber; shaft means located in said passage and rotatably mounted on said body, said shaft means having a head located in said chamber and a longitudinal passage open to the chamber, said head having a transverse dimension larger than the transverse size of the passage in the body whereby the head limits axial movement of the shaft means relative to the body; means for carrying fluid under pressure to the passage in the body whereby fluid flows from said passage in the body into the chamber and around the head and into the passage in the shaft means, said fluid subjecting the head to opposite longitudinal forces to substantially longitudinally balance the shaft means in the body, and fluid discharging means mounted on the shaft means to receive fluid from the longitudinal passage in the shaft means, said fluid discharging means being operable to rotate the shaft means in response to the discharge of fluid therefrom.
