Emptying the tank
The methods of emptying the dirty water out of the vacuum tank that are in common use are (A) a flexible pipe with a bung at it’s end and (B) a gate/drain valve.
Both are cumbersome protrusions on the outside of the machine. They leak after some use, controling the water flow out can be difficult and often results in spillage (especially when the valve becomes stiff) and both methods leave a certain amount of dirt and water behind in the tank, resulting in dirty and smelly tanks.
The design of the Predator eliminates the need for these systems. The dirty solution in the vacuum tank is simply poured out of a lip at the front of the machine. The height of the lip is correct for emptying into a 20 litre bucket or a toilet. The tank can also be emptied directly into a drain if available on the premises, this will enable the entire 40 liters to be emptied quickly and with a minimum of effort. The pouring action is easily learned by the operator and no splashing or mess will occur. The tank shape is designed so that the weight is distributed forward towards the pivot point. The pivot system enables every drop of dirty solution to be emptied, leaving a completely clean tank. This system cannot block or malfunction and requires no maintenance. A further advantage of this system of emptying is for flood recovery work, the machine could be positioned near a toilet or drain thus enabling the contents to be emptied quickly and therefore improve the speed of flood recovery
Daily maintenance and cleaning of conventional machines is often difficult due to small access lids and poorly positioned filters. Cleaning the remaining sludge in the recovery tank is almost impossible.
The predator’s tanks are easily rinsed and cleaned at the end of each day, the owners manual describes a simple proceedure that will not only keep the machine clean but will also prolong the life of the motors. The filters are easily removed and can be dis-assembled for complete cleaning.
Servicing and maintenance.
Servicing of some machines can be difficult due to poor access to the motors and over-complicated mounting and electrical layouts. This results in longer down-time and often incorrectly done maintenance. We have paid special attention to this aspect of the Predator. Any repairs or maintenance work can be carried out simply.
The systems are clearly laid out and easily accessible. Changing the pump for example can be done in ten minutes. Access to the motors is via an aluminium mesh cover underneath the machine. All the working parts in the Predator are commonly available worldwide, so wherever you may be in the world the replacement parts or equivalent will be available.
Vacuum and solution tank capacity ratio.
There are many designs of machine that have a much smaller recovery capacity than the solution tank capacity.
The problems with this capacity ratio are that the safety or high-level cut out mechanism is used each time the recovery tank is full, this we find results in too much moisture going through the vacuum motors, resulting in premature failure of the motors. This tank capacity ratio is also an in-efficient system for the operator as they have frequent stoppages for emptying. In our opinion the effective size of a machine is determined by the smaller of the two tanks.
The Predator has a 40 litre solution tank and the recovery tank cuts out at 40 litres. This means that all the solution is extracted from the carpet without activating the cut-out mechanism. The cut-out mechanism only comes into play when flood recovery work is done. The operator can only re-fill the solution tank once the recovery tank has been emptyied because the recovery tank is situated above the solution tank, this reduces stoppages during work and results in more efficient use of time. Machines of this size are bulky and heavy and difficult to load and unload.
Transport and manuvering.
Many have wheels at the rear to assist up and down stairs, but this is very difficult if a few flights need to be climbed. Many operators use small sedan cars, fitting a 40 litre machine into such a vehicle is extreemely difficult and usually results in damage to machine, vehicle and the operator!
The Predator seperates into two sections. The lower section is the solution tank with the motor compartment, (weight 28kg). The upper section is the vacuum tank (weight 13kg). These sections are therefore smaller and lighter than the machine as a whole. They are easily carried up and down stairs, they fit into the smallest vehicles with ease and loading and un-loading is much easier.
