I use 4 things to clean my house-bleach, window cleaner, wood cleaner (like Murphy's Oil soap) and furniture polish. I also have a container of cleanser which comes out very rarely for a stubborn sink stain...I think I've had the same container since we moved into the house 18 years ago!
The bathrooms are cleaned with bleach with the exception of the wood vanity which gets cleaned with the window cleaner and at least a few times a year gets a wipe down with the Murphy's Oil soap to clean and refresh the wood.
My wood floors get cleaned with a window cleaner/water 50/50 mixture because of the type of finish the installer used. This is per his instruction.
Kitchen gets cleaned with window cleaner for appliances/coountertop. cabinets get Murphy's Oil Soap. If there's raw chicken or pork on the counter, the bleach spray comes out.
Wood furnture gets the furniture polish.
Woodwork gets the Murphy's oil soap. Windows get the window cleaner.
I like the "KISS" method of housecleaning. All these fancy cleaners are totally unnecssary IMHO.
My vacuum is an Oreck. I've had it for a number of years...probably at least 15...and have had no problem with it. Simple upright vacuum....cost about $300 at the time of purchase.
Rugs get done once or twice ayear with a rented steam cleaner.
