- releasable connecting means on said powerbase communicating with said enclosure, said solution supply means, and said direct current supply,
- a powerhead member comprising a housing having top and side walls,
- front and rear supporting means on said housing for transporting the same over a carpet surface,
- means on said housing cooperable with said supporting means for selective vertical adjustment of said housing relative to the carpet surface,
- a handle pivotally connected to said housing and height adjusting and locking means therefor,
- releasable connecting means on said handle operatively connected to said first-named releasable connecting means for connecting said powerhead to said enclosure, said solution supply means, and said direct current supply of said powerbase,
- suction means having a bottom air inlet and a top air outlet extending transversely across and pivotally mounted in said housing near the front wall thereof to contact and ride upon the carpet surface comprising;
- a hollow inverted generally T-shaped tubular member having an elongated bottom portion with two opposed closed ends and an open ended hollow stem portion extending angularly upward therefrom,
- a longitudinally extending slot disposed on the underside of said bottom portion terminating before said opposed closed ends for the induction of air,
- slotted brackets attached to side walls of said housing,
- pins extending outward from each of said closed ends slidably received in said bracket slots for pivotal and rotary movement,
- compression springs biased against the underside of said powerhead top wall and mounted on vertically extending pins disposed on each of said closed ends to urge the same downward onto the carpet surface,
- air conduit means on said powerhead comprising:
- a clear plastic tubular member secured to said handle,
- a section of flexible hose having one end attached to said open stem portion of said suction member and the other end attached to the lower end of said clear plastic tubular member,
- said second-named releasable connecting means including a flexible hose connecting the upper end of said clear plastic member to said releasable connecting means on said powerbase member,
- a front and rear solution dispensing means in said powerhead member communicating with said liquid supply means in said powerbase member including control means for selectively dispensing solution uniformly across the carpet surface comprising;
- a front set of spray nozzles carried on said suction member and disposed relative to said slot with the tips of said nozzles at predetermined height thereabove,
- a rear set of spray nozzles carried on said suction member and disposed rearwardly of said slot whereby solution may be applied to the carpet surface in a rearward motion just prior to extraction by said suction member,
- a first tee fitting,
- a first tubing having one end attached to said front nozzles and the other end attached to one end of said first tee fitting and a valve means interposed therebetween to control the liquid flow therethrough,
- a second tubing having one end attached to said rear nozzles and the other end attached to another end of said first tee fitting and valve means interposed therebetween to control the liquid flow therethrough,
- a second tee fitting,
- a third tubing having its lower end attached to the remaining end of said first tee fitting and its upper end attached to one end of said second tee fitting and two opposed releasable connecting means extending outwardly therefrom,
- a fourth tubing having connecting means at each end for attaching said connecting means on said powerhead member to said connecting means on said powerbase member to supply said dispensing means with various liquid solutions,
- brush drive means supported on said housing comprising a vertically disposed 24 volt D. C. drive motor,
- a second power line connecting said transformer to said motor,
- a transmission including a worm gear and two counterrotating laterally extending worm gears driven thereby,
- sheaves attached to the extended ends of said worm gears
- brush means extending transversely across said housing behind said suction member and supported in a plane parallel to the carpet surface comprising;
- elongated tubular stainless steel front and rear brush tubes journalled on axles extending between the housing side walls and having circumferentially disposed spirally wound outwardly extending bristles thereon,
- a sheave smaller in diameter than the extended ends of said bristles disposed on each said brush tube in alignment with said sheaves on said worm gears, and
- a timing belt connected therebetween to drive said brushes in counterrotational movement.
