Kärcher 'MV 2' Vacuum Cleaner - Wet and Dry (City of Bristol BS5)

Kärcher 'MV 2' vacuum cleaner
Wet and dry cleaner, will suck in anything, including liquids (the body of the machine acts like a bucket).
Powerful (noisy !) and useful, especially at unblocking drains
Has been well used, but functions as it should, though ...
... hose end is attached will a length of bicycle inner tube, one attachment mount has broken off
Please say what you might use it for - thanks
