Bosch Aquatak Go

The tiny Go follows you around a bit like a dog on a lead, which would be fine if the water hose wasn’t quite so hefty.

The result is that the unit keeps falling over in operation, although we like the way the base can be removed and the pump carried. Accessories are limited to a soap bottle and storage is non-existent.

Power is in short supply, too – the Bosch is much better suited to cleaning gutters than bodywork.
