Commercial washer and dryer cost $400 to $500 more than a typical household washer and dryer. Domestic washer and dryer are just as rugged and operate exactly the same way. The only difference is that a commercial washer and dryer have coin device WIRED DIRECTLY to the machine and if it breaks down the repair is not cheap.You pay for a service call (around $80 minimum) plus parts and It can be out of commission for weeks. SMARTCOINBOX is designed to control the electrical power flow to the washer/dryer through an electrical plug-in. This device would mount on the wall just above the machine and the machine would plug directly into the device. SMARTCOINBOX takes USA Quarter or TOKENS (coin included/installed) and will run for preset time per coin. There is a countdown display that accumulates every time a coin is inserted. Say $ 1.00 for 30 minutes or $1 per 45 minutes (CANADA) or $0.25 for 8 minutes or $ 0.25 for 10 minutes (USA). The machine will stop after the accumulated time REGARDLESS of the machine cycle status. The intended applications of this controller are student housings, rooming houses and basement apartments especially if laundry is included in the rent being collected. SMARTCOINBOX can also be programmed to take a certain number of coins before machine power up. This duplicates a Commercial Coin laundry machine where in you insert say 5 quarters then push the lever energizing the appliance. In case of the SMARTCOINBOX, the tenant will insert X number of coins as programmed then after the last coin the appliance powers up.
