PS: the manual comes WITH it! ;-))
Radek, been reading the ebay auction more closely, they have the booklet included. Here is the auction in English:
"...Hallo,
finally I have decided to let go of my loyal helper. The Hoover Aquamaster has always been doing a great job but by now it is only standing around. I only wouldn't get rid of it for some longer time as it has always worked extremely well. Here we go:
You are bidding on a Hoover Aquamaster S4480 wet- and dry vacuum that is perfect for cleaning upholstery as well. Except for the duster brush (that I can't find anymore), all tools are complete: suction hose, 2 tubes, carpet and floor nozzle for dry vacuuming, utility nozzle for wet- and dry jobs, crevice tool, carpet cleaning nozzle, upholstery cleaning nozzle.
On top of that you get 3 spare bags and the user's manual.
The Aquamaster very flexible to use, it glides on 5 wheels and has a very long cable. Suction can be adjusted via an electronic control knob. Volume 17l dry dust, ca 5l cleaning solution.
As usual: private sale, so there is no refund, no guarantee.
Have fun vacuuming!.
