Abstract

A hand-held, electric-powered cleaning device used to wash elevated or difficult-to-reach surfaces. The device includes a length adjustable elongated pole with a rotating brush assembly attached at its distal end. Attached to the proximal end of the elongated pole is a handle assembly that includes a battery housing and a hand grip assembly with a brush control switch and a hose connector fitting. Disposed inside the elongated pole is a coiled water conduit that connects to a standard hose fitting located in the end of the handle assembly and terminates in the brush assembly to deliver water to the brush assembly. Also disposed inside the handle assembly is a soap delivery system to deliver soap to the water conduit.

Claims

1. A hand-held cleaning device, comprising:

a. A telescopic elongated pole, said elongated pole having a distal end and a proximal end;

b. a brush assembly attached to said distal end of said elongated pole, said brush assembly including an electric motor, a circular shroud with outer fixed bristles and a rotating brush located inside said shroud and connected to said electric motor;

c. a handle assembly attached to said proximal end of said elongated pole, said handle assembly including a hand grip housing and a battery housing;

d. a water conduit disposed inside said elongated pole and said handle assembly to deliver water to said brush assembly;

e. a soap delivery system that automatically delivers soap to said water conduit as water flows through said water conduit;

f. a rechargeable battery located inside said battery housing and electrically connected to said electric motor;

g. a switch located inside said hand grip housing and connected between said rechargeable battery and said electric motor;

h. means for recharging said rechargeable battery; and

,

i. means for connecting a hose to said central conduit for delivering water to said central conduit.

2. The cleaning device as recited in claim 1, further including a mount for temporarily storing said device on a wall.

3. The cleaning device as recited in claim 2, wherein said means to recharge said rechargeable battery is a recharging unit located inside said mount.

4. The cleaning device as recited in claim 2, further including a brush receiver attached to said mount to hold a replacement brush.

5. The cleaning device, as recited in claim 1, further including a hand grip attached to said elongated pole enabling said distal end of said elongated pole to be selectively rotated while supported.

6. The cleaning device, as recited in claim 5, wherein said elongated pole includes a longitudinally aligned inner tube and outer tube that move telescopingly to adjust the length of said elongated pole.

7. The cleaning device as recited in claim 1, further including a coupler disposed between said elongated pole and said brush assembly to selectively connect said brush assembly to said elongated pole.

8. The cleaning device as recited in claim 1, wherein said water conduit is coiled inside said elongated pole.

9. The cleaning device as recited in claim 1, wherein said brush assembly and said handle assembly are approximately equal in weight.

10. The cleaning device as recited in claim 1, wherein said battery housing is located in front of said hand grip housing.

11. The cleaning device, as recited in claim 1, wherein said means for connecting a hose to said central conduit is a delivery conduit that extends through said handle assembly.

12. A hand-held cleaning device, comprising:

a. an elongated pole that is adjustable in length and having a distal end and a proximal end and including a longitudinally aligned inner tube and outer tube capable of being telescopically adjusted in length;

b. a brush assembly attached to said distal end of said elongated pole, said brush assembly including an electric motor and a rotating brush connected to said electric motor;

c. a handle assembly attached to said proximal end of said elongated pole, said handle assembly including a hand grip housing and a battery housing;

d. a water conduit disposed inside said elongated pole, said water conduit terminating at one end in said brush assembly and at an opposite end at said handle assembly;

e. a soap delivery system including a reservoir for holding soap and a central conduit that connects to said water conduit, said central conduit including a plurality of holes formed therein to enable soap to enter said central conduit via capillary action when water flows through said central conduit;

f. a rechargeable battery located inside said battery housing and electrically connected to said electric motor;

g. a switch located inside said hand grip housing and connected between said rechargeable battery and said electric motor;

h. means to recharge said rechargeable battery; and

,

i. a mount for temporarily storing said device on a wall.

13. The cleaning device as recited in claim 12, further including a shroud attached to said brush assembly and extending over said brush, said shroud including means to prevent water from said brush from spraying outward during operation.

14. The cleaning device as recited in claim 12, further including a brush receiver attached to said mount to hold a replacement brush.

15. The cleaning device as recited in claim 12, further including a coupler disposed between said elongated pole and said brush assembly and used to selectively attach said brush assembly to said elongated pole.

16. The cleaning device as recited in claim 12, wherein said brush assembly and said handle assembly are approximately equal in weight.

17. The cleaning device as recited in claim 12, wherein said battery housing is located in front of said hand grip housing.

18. The cleaning device, as recited in claim 12, wherein said means for connecting a hose to said central conduit is a delivery conduit that extends through said hand grip housing.

19. The cleaning device, as recited in claim 12, further including a handle grip rotatably mounted on said elongated pole enabling the elongated pole to be supported with one hand while rotated with the opposite hand.
