Calculating the Cost Benefits of an Autonomous Cleaning Equipment Purchase
The cost of labor can account forup to 85%of the cleaning costs for your facility.
由于清洁过程可能是耗时的，因此充分利用每个清洁班对于在不增加劳动力费用的情况下实现最多的情况。
正确的清洁设备是确保您的员工尽可能清洁的方式。自主清洁设备是最具创新性和最有效的方法，可以帮助您的员工在清洁班次期间做更多。
自动清洁机器是电池供电的老虎设备，可以在不需要人类运营商的情况下运行。
Autonomous cleaning equipment can help you do more by reducing the amount of time your staff spends doing repetitive cleaning tasks. With the right autonomous cleaning equipment, you can redeploy staff to other more important cleaning tasks, achieve consistent cleaning, and increase worker safety.
Now that you have a brief understanding of thebenefits that autonomous cleaning equipment可以提供，您可能会问，“自主清洁技术的成本是多少？”而且，作为这个问题的后续行动，您可能在思考，“我可以负担得起这项投资吗？”
虽然自主设备可以带有高价格标签，但这并不意味着它不经济。
自动清洁机的成本似乎很高，特别是当您在预防性维护成本，长期维护，维修和任何升级费用中时都会很高。
However, the right equipment can offer your business large savings through lower labor, chemical, and water costs.
In this article and video, we’ll help you understand what is considered a good购买by determining the return on investment of your equipment.
什么是ROI？
投资回报率或投资回报，是对投资或购买的有利可比度的测量。
When you purchase new equipment for your facility, the ROI of that purchase is the amount of money that is generated or saved by your equipment investment.
ROI can be expressed as a percentage or dollar amount over a certain period of time.
为什么ROI重要？
ROI can be useful in helping you decide whether or not autonomous cleaning equipment would be beneficial for your facility. Knowing the return on investment of your equipment purchase can help you make better equipment purchasing decisions.
如果您计算购买设备的投资回报率，您将确切地知道您的投资需要多长时间才能支付自己。
Once an investment has paid for itself, any additional savings would contribute to the ROI of your purchase.
If your equipment is generating a positive ROI, that means your investment has paid off and isearning or saving你钱。
How Do I Calculate The ROI Of An Equipment Purchase?
计算设备购买的确切投资回报率可能是具有挑战性的，因为有这么多因素。
We’ll break it down into 7 simple steps.
要计算ROI，您需要量化的一些因素包括：
- Total Square Footage to be Cleaned
- Frequency of Cleaning
- 在当前进程中完成清洁任务所需的平均时间
- 考虑使用自动化设备完成清洁任务所需的平均时间
- Payback Period
- Loaded Cost of Labor (Hourly Rate, Benefits, Liability Insurance)
- 平均化学品和水
- Average Lifespan of the Automated Equipment in Consideration
- Initial Cost of the Automated Equipment in Consideration
To help you understand how to calculate the ROI of an equipment purchase,我们将带你通过计算的步骤ROI for an autonomous floor scrubber below.
- Step 1: Identify Total Square Footage & Frequency of Cleaning
- 第2步：确定员工的负载劳动成本
- Step 3: Identify the Yearly Labor Costs of Your Current Cleaning Method versus the Costs of Running an Autonomous Machine
- 第4步：计算近似化学和水资源（如果可能）
- Step 5: Calculate The Payback Period
- Step 6: Calculate the Savings Over the Lifespan of Your Equipment
- 第7步：确定ROI
Step 1: Identify Total Square Footage & Frequency of Cleaning
第一步确定ROI可以achieve from an autonomous machine purchase is identifying how much floor space your staff typically cleans in a shift.
This measurement should be the amount of cleanable space, taking into account obstacles, such as desks, file cabinets, and other obstructions to your staff’s cleaning route.
例如，虽然您可以管理50,000平方英尺的设施，但由于家具，固定装置或其他物体，待清洁的地板的平方英尺只能为35,000平方英尺。
接下来，您需要考虑地板清洁的频率。
您的设施中的地板清洁频率取决于各种因素，如交通量和土壤水平。虽然某些设施仅在每天一次清洁地板，但其他一些设施可能需要更频繁地清洁地板以保持清洁的外观。
In our example, our staff cleans the floors twice every day. Accounting for the occasional holiday or day off, we’ll be using 360 days as the frequency of floor cleaning.
第2步：确定员工的负载劳动成本
In case you’re not familiar with what the loaded cost of labor is, an employee’s loaded labor cost includes everything your business would have to pay for an employee to complete an hour of work.
值得注意的是，员工的负载劳动成本不仅仅是他们的每小时薪水。要弄清楚员工的加载小时劳动力成本，您应考虑每小时支付率，税费，责任，责任保险和其他相关费用。
将所有这些成本在加载的每小时劳动力率占雇主必须支付一小时工作的费用。
当您尝试计算购买设备的投资回报率时，您需要考虑拥有员工获得准确回报时间范围的所有成本。
For the sake of this example, we’ll use the loaded labor rate of $32.50/hr.
Step 3: Identify the Yearly Labor Costs of Your Current Cleaning Method versus the Costs of Running an Autonomous Machine
了解运行当前设备的年度劳动力成本将帮助您通过升级设备来计算您可能会省略多少劳动力。
How do I calculate the yearly labor cost of my current cleaning method?
To calculate the yearly labor cost of your current cleaning method you’ll need to know both your loaded cost of labor and the amount of time it takes to complete cleaning in your facility.
For the sake of our example, we’ll be comparing a 20-inch walk behind floor scrubber to a 20-inch自主地板洗涤器，这将是等效大小的模型。
According to the ISSA 612, a 20-inch walk-behind scrubber can clean approximately 20,000 square feet an hour.
So for our facility, that means it would take approximately 1.75 hours to clean 35,000 square feet. Since our staff will be cleaning twice a day, it would take them about 3.5 hours total to clean our facility twice.
根据同样的ISSA研究，每天维护自动地板洗涤器（准备机器，倾销和重新填充坦克，以及日期清洁）通常需要大约半小时。维护需要完成两次，因此每日维护需要一个小时的清洁时间。
Given that, you’ll need to add an hour to your floor cleaning routine. This means that it takes about 4.5 hours (3.5 hours to clean our facility’s floors + 1 hour for machine maintenance) for our cleaning staff to clean the floors of our facility.
为了计算每日加载的劳动力成本，清洁35,000平方英尺两次，您将通过工作人员需要努力完成清洁的时间乘以加载的劳动力成本。
如步骤2所述，我们为我们的例子使用的负载成本为32.50美元。
(loaded hourly labor cost) x (hours worked) = daily loaded labor cost
$ 32.50 x 4.5 = $ 146.25
接下来，您需要计算年度劳动力成本。自从您拥有日常的劳动力成本以来，您只需要在工作的日期乘以。
如步骤1所述，我们使用360天为我们的年度工作量使用。
(daily loaded labor cost) x (amount of days worked) = yearly labor costs
$146.25 x 360 = $52,650
在一年的过程中，使用20英寸的步行式洗涤器将在劳动中花费约52,650美元。
How do I calculate the yearly labor cost of running an autonomous cleaning machine?
Since an autonomous floor scrubber can run without an operator, your staff would only be responsible for the daily maintenance of the machine, which includes preparing the machine, filling and dumping the tanks, and end of day cleaning. As previously stated, daily maintenance takes about half an hour, and when done twice a day your staff will spend an hour on maintenance.
(loaded hourly labor cost) x (hours worked) = daily loaded labor cost
$ 32.50 x 1 = $ 32.50
An autonomous floor scrubber would only cost abou每日劳动力成本为32.50美元。Using the same formula as before, you can calculate your yearly costs for cleaning with an autonomous floor machine.
(daily loaded labor cost) x (amount of days worked) = yearly labor costs
$ 32.50 x 360 = 11,700美元
年度劳动力储蓄总数是多少？
To calculate your yearly labor savings, you can subtract the yearly cost of running your current machine from the yearly cost of running an autonomous floor machine.
(current machine labor cost) - (autonomous machine labor cost) = yearly labor savings
$52,650 - $11,700 = $40,950
使用自动楼层洗涤器清洁可最大限度地减少操作员错误，例如错过的斑点，损坏或其他错误，否则可能会导致返工。
With the addition of autonomous floor cleaning machines, you can achieve between 98% and 99.5% floor cleaning coverage every time due to pre-programmed paths that ensure the machine cleans the same every time - never forgetting or missing an area. When operators use standard floor care equipment, they typically miss about15％的空间没有意义，导致昂贵的返工。
在我们的经验中，返工每年的返工可能需要多达500美元，这将避免自主清洁剂。
第4步：计算近似化学和水资源（如果可能）
清洁地板的成本包括清洁化学品和用水的成本。
Depending on the method and machines used, this can vary. The cost will also depend on how much chemical and water usage costs for your facility.
In our example, water costs about$7.00 per 1,000 gallonsin our area. Autonomous floor scrubbers can use anywhere between 40-70% less water than a traditional autoscrubber, which translates into cost savings of about $7-10.
使用较少的用水量，您还可以在您的设施中节省您的化学用途。由于自主洗涤器清洁化学品，我们可以估算约840美元的节省。
Given that, we’ll estimate our chemical and water savings to be around $850 a year.
Step 5: Calculate the Payback Period
The payback period of an investment is simply the amount of time it takes to make back the amount of your initial purchase. After the payback period, your investment begins to save you money.
To calculate the payback period of a purchase, you will need to know the total approximate savings you will be generating over a year. This can be calculated by adding up the savings (labor, rework, chemical, and water), which we just showed you how to calculate above.
You can calculate your total yearly savings using the equation below:
(labor savings) + (chemical & water savings) + (rework savings) = yearly savings
$40,950 + $850 + $500 = $42,300
在我们切换到自主地板的示例中，我们可以每年节省42,300美元，而不是使用步行后磨机时。
Then, to calculate the payback period, divide the yearly savings by 12 to get the monthly savings.
(yearly savings) / 12 = monthly savings
$42,300 / 12= $3,525
Next, divide the price of the new equipment you’re looking to purchase by the monthly savings. Thiswill tell you the number of months it will take to recoup the cost of purchasing your autonomous equipment.
（购买成本）/（每月储蓄）=投资回收期
$58,000 / $3,525= 16.5
如果新的自主洗涤器费用为58,000美元，则购买需要大约16个月的时间来支付劳动力储蓄。这有点超过一年。
Step 6: Calculate the Savings over the Lifespan of Your Equipment
To calculate the labor savings a machine will generate over its lifetime, you’d want to know the average lifespan of the machine you’re investing in. You can multiply the yearly savings by how long your investment should last.
(yearly savings) x (equipment lifespan) = lifetime savings
$42,300 x 7 = $296,100
The average lifespan of an automatic floor scrubber is 7 years, which would mean that in our example we will save roughly $296,100 over the lifespan of the equipment.
第7步：确定ROI
最终计算您购买的ROI，您将从您的设备的寿命中从计算的节省中减去购买金额。由此产生的数字将告诉您您的购买需要多少钱作为您的投资回报。
(lifetime savings) - (equipment cost) = ROI
$ 296,100 - $ 58,000 = $ 238,100
The ROI in this example will be approximately $238,100.
Final Thoughts
Knowing the ROI of your equipment purchase can help you determine whether or not your purchase is beneficial to your business.
The ROI of equipment is dependent on various factors, such as the amount of time a task takes, labor costs, original equipment cost, common lifespan of the equipment, and average maintenance costs.
