The house is 2000 sqft, no carpet, two rugs total in two bedrooms rest is hardwood and tile floor so easy to clean. Our cat doesn't shed much and we regularly vacuum the house. This support will be needed for vacuuming, mopping and bathroom cleaning. one of the full bathrooms occasionally used so fairly stays clean. the other full bathroom and the half bathroom are used daily. 4 hrs duration was selected based on how long it takes one person to complete the cleaning needs explained above.
