Pricing House Cleaning Assignments

So far we have developed the model for estimating weekly and biweekly cleaning man-minutes by taking into account various house attributes, usage variables, and execution factors. The model has a mathematically simple form, yet yields quite satisfactory results. However, it has some limitations in that the execution factors are not specific to each cleaning assignment and usage factors are subjective in nature.

The results show that the square footage of the house (including basement), the number of bathrooms and showers, lifestyle, floor, and pet factor are the main determinants of cleaning time along with the number of team members, the time elapsed between cleanings, whether the client is present, and revenue per person. The extra work required for biweekly cleaning is also influenced by the number of inhabitants and square footage. For example, based on the average size house with average number of occupants, it would require additional 19 man-minutes for a biweekly cleaning as compared to a weekly cleaning.

The model can be used to estimate cleaning time with a confidence level of 87%, allowing a 25% error.

As more fully discussed in Section 16 below, in terms of opportunities for further discoveries, further work might be beneficial with respect to the following:

“Ball-parking” estimates for initial cleaning assignments is not for the faint of heart. If you can find someone who has really bothered to keep track of their own accuracy in quoting initial cleaning assignments, you’ll find that they won’t be bragging much about their record. This is because it is very difficult to accurately predict cleaning times for initial cleanings.

Of course, we did not consider performing a statistical analysis of how long it takes to perform initial cleanings.  The initial cleaning formula included in the model provides a “better than nothing” tool to assist someone performing an in-home estimate to arrive at a ball park estimate.

Better to overstate the limitations, so let’s step out on a limb on this one: 1) the HCA Pricing Tools are totally devoid of any insights into how much time it’s actually going to take for the initial cleaning; and 2) the HCA Pricer cannot be used to determine the true meaning of life. Sorry, you ‘re still on your own for both.
