This battery operated 22 inch scrubber dryer from Numatic is one of the best priced scrubber dryers in the world. The operator chooses when & how much of this solution is fed down through the heavy duty scrubbing brushes on the front of the machine. The rotation of the brushes gently pulls the machine along making the cleaning process practically effortless. At the rear of the machine a curved vacuumated squeegee collects the slurry & deposits it into the 40L waste tank. When you have finished the task simply take the machine to a drain & empty the dirty water through the drop down hose. This latest Twintec model is more manouverable than ever having a tighter turning circle especially important in more confined areas. This machine will hold up to 40L of cleaning solution. It comes complete with 2 x11 inch polypropylene scrubbing brushes each powered by an independent motor giving greater cleaning efficacy.You can expect a run time of around 2.25-3 hours from this machine & a recharge time of 8-10 hours. The batteries are maintenance free (i.e. no need to top up with distilled water) & to charge the machine you simply park the machine next a conveniently placed point & plug it in!
