So many reasons. Durability – as our motor spins in a precise balanced rotation, not the unbalance rotation of an OP unit. So balanced, items run much smoother, quieter and will last longer. This means less noise for your customers and you, no vibration and shaking depending on the OP model that can be fatiguing, and can be disturbing to people under you while cleaning the second floor or higher in the building you’re servicing.
While the rotary requires a little more operator input, you’re rewarded with complete freedom of movement in any direction and this increases your cleaning speed. The OP requires you to move forward and then back. When you pull back you have a cord to trip over. That gets old very fast. With the MiniMax you work your way away from the outlet and this reduces or eliminates having to constantly move the cord out of your path.
The OP does not use a gearbox and is therefore weak on torque. This is why their motors hang off of the main frame and requires wheels to push and pull the machine. This also means in most cases, the OP has less head weight and this means less push into the bonnet, brush or pad. The deeper I can reach the better I can clean!
The OP also has fewer options for bonnets and cannot use a brush on the carpet due to the weak torque of that style of machine. You are limited to a center stitched bonnet or single layer bonnet. The 1.5 hp high torque of the MiniMax always the use of any bonnet in the market place, any carpet safe brush or encapsulation pad and even the use of the high performance Multii Brush from Bonnet Pro! Why limit yourself? Cleaners who demand the best choose MiniMax!
