The objective would be payroll savings vs. the cost of the machine.
Our housekeeping staff works out of full size vans, so transport space is not really an issue. Some consideration to lugging that thing up-the-stairs needs further thought. I also understand that not every apartment may have a use. However, cleaning two bathrooms in an apartment takes somewhere between 35 and 40 percent of the time of the entire job (the bathtubs and surrounds in particular are the most time consuming part of the bathroom). Additionally cleaning up the vinyl floors (after some of the painters) is currently labor intensive and a pressure washer makes short work of latex paint on vinyl. The psi of the top end machine is 500, but the flow is only 1gpm. Is there enough flow?
Occasionally when we clean the carpet prior to an apartment housekeeping job, I'll have them prespray the vinyl floors, bathtubs, toilets and then hit it with the pressure washing wand and suck-up the mess with the vacuum hose. I've even had them opened the refrigerator door and spray it out and sucked it up too. Other than the windows, oven, ceiling fans, bathroom mirrors and counter
tops, I'm thinking a large part of an apartment can be done with this type of system and save 30 to 45 minutes per job and perhaps reduce a four person crew to a three person team plus one Kiavac.
However if it's hard to push, difficult to get up-stairs, takes too long to set-up/take-down or is in other ways cumbersome to use, our teams are pretty quick to cast out bad ideas - even if those bad ideas are mine.
