Vax Carpet Spot-Scrubber (St. Dunstan's CT2)

Vax mini carpet spot cleaning machine, for spills & pet "incidents, muddy boot prints etc.
Quite old & well-used (& now replaced with a much newer version) but still does the core job of sucking moisture out of the carpet just as well as it ever did.
By design, the blue tank contains a mix of water & detergent, & has a little thumb-pump built in to spray that on to the carpet, let it soak for a moment, the rotating brush underneath works that in the carpet & then it sucks the dirty water back out & collects it in the grey tank.
In practice the pump was hopeless & we quickly learned that that for spills, just suck it up then clean, for dried muck, rub some of the excellent Dr Beckmann carpet cleaner (available in all supermarkets) into the dirt, wait a minute or two, dribble some water onto it from a cup, then use the machine to suck the dirt up. If muck is more widespread or stubborn, get one of those cheap pump sprays that gardeners use, fill that with a mix of hot water & carpet detergent & wet the dirty patch with that mix, rinse & repeat 'till clean.

Collection from Whitstable Road area of Canterbury CT2, please.
