Question: What wax do you use with this machine??
Document: Arrived very fast and has been a pleasure to use on Bruce Hardwood floors wax finish. This machine is heavy enough to do a great job on the floors but light enough to carry up and down stairs, I would purchase this product again or recommend to friends. Amazon service was great as always.
I have old hardwood floors that will eventually be refinished. In the mean time, paste wax protects and keeps them looking nice. I use the machine to put the paste wax on and then change to a buffing pad and buff the dried wax. The only complaint that I might mention is the pads sometimes come off and fly across the room. It's a little frustration compared to how difficult it would be to wax an entire house on my hands and knees.
This is a very easy to use floor cleaner/polisher. The packing was good and it was very easy to assemble. I have all hard floors in my house, so this will definitely cut down on elbow grease. I made a mistake in ordering the pads and did not get the pads to apply wax (buffer). The correct pads are on the way so can't wait to try this out!
It's such a pleasure to have the floors looking new and shiny all the time now. I can polish anytime (I use Johnson's Paste Wax) and the whole house seems cleaner.My only complaint is the flimsy pads that come with it. They don't last and because they are attached to the brushes through the middle of the pad, the cleaning/buffing surface is just on the perimeter of the pads.Solution?
The brushes are necessary because any pads you use go on top of the brushes. I buffed my floors with the tan pads, and they worked great. I have about 1800 sq feet of floor, and after going over most of them with the tan pads, the pads still look fine. Like new. I have not added any new wax to the floors yet. Just buffing the existing wax made the floors look new.
I have 1300 sq/ft hardwood floors with wax finish and this does a great job applying and polishing. The only ding is on the polishing pads that came with the machine but I cut down some full sized pads (find them at your local equipment rental store) and they work great.
If you've never had a wax-type floor (which I hadn't), the whole thing can be a little intimidating. But you'll do fine with this machine; just err on the side of caution with the brushes and pads.Edit: I discovered the wool pads can be very easily machine-washed on the hand-wash cycle, in a mesh bag, with Woolite and warm water - and the spin cycle gets rid of most of the leftover moisture. It worked fine for me.
This floor cleaning machine was purchased to Wax, Buff and polish stained concrete floors in my personal home. About 2000 square feet of the house are stained concrete floors. The Koblenz P-620A makes for a quick fix to scratches and an inexpensive way to burn additional wax in, when necessary. I am very pleased with this purchase off of Amazon and would recommend it for someone maintaining a residential area no more than 2000-3000 square foot. Easy to clean and change out pads and brushes.
The machine is light and easy to use.
This floor buffer really would be even better for floors that had been paste wax prepared. It doesn't erase scuff marks on hardwood floors that I had used a liquid polish to get a shine.
Answer: Basically you can use either a paste wax or a milk. I have three different kinds of flooring- Perco, Walnut, and Cork. The Walnut requires no wax; however, I use Bioshield's floor milk on the other two. You simply apply the floor milk with a cloth applicator; let it dry; then use Koblenz's grey buffing pads to give the floor a deep shine; and then follow with the lambs wool pads to give it a very smooth shine. (On the perco floor, I originally used Martha Stewart's Wood floor cleaner with no wax and just used the buffing pads to enhance the shine that comes naturally with the cleaner; but I get an even brighter shine with Bioshield's floor milk.)
