Eliminate guesswork from your cleaning contracts, forever

Regardless of the size of building, dimension or number of rooms, layout of fixtures and type of floors, The Cleaning System enables you to quickly assess the time required for each task.

It is both proven and ideal for hospitals and healthcare facilities, hotels, colleges and universities, and public buildings, to name a few.

You can also quickly and easily assess how long it takes to clean a single area, how changes to a job (for example, its frequency) can impact your bottom line, and create reports for each of your contracts and individual staff members.

All times have been developed and fine-tuned for over 20 years in thecleaning industry as well as incorporating the ISSA 540 times. Variables are service levels required, traffic, equipment used, staff productivity, visits per week etc.

A free list of the ISSA 540 cleaning times can be obtained here.
