I recently moved from an apartment to a large house and was overwhelmed with how much cleaning I had to do and how time consuming this was ( I moved from a small apartment to a 4-bedroom house). Plus, I must say I get a bit OCD when it comes to cleaning. I bought a Dupray Tosca a few weeks ago and I use it for literally everything. It gives great results and gets into all those little nooks and crannies you can't normally clean. Overall its a very practical tool to have in your house (especially if you're having renovations like I do), although it is an investment (prices started at 1000$ , which is not cheap for a residential cleaning unit).
