A great value for money. Viper AS510B is easy to use battery operated walk behind floor scrubber due its built-in charger, reduced pushing force and ergonomic start/stop switch.
The solution and recovery tank is integrated into one mould to create higher tank capacity. The cover of recovery tank is much bigger and makes it easier to clean.
It has an easy to fill clean water tank, both brush and vacuum motors are very well protected from water splash.
Compared to Viper AS430B, it has a bigger brush.
