Perfect for my project!

I was hesitant to purchase this floor buffer after reading a couple of reviews (particularly one saying the buffer didn’t actually rotate but only vibrated and one saying it was too heavy). It in fact DOES rotate and I’m a 70 year old woman that managed its size and weight easily. It is probably about 200 pounds and was heavy enough to do a great job. I used it to refinish my old, tired concrete floors and was thrilled with the outcome. I first used the scrub pad to clean the floors with a concrete cleaner then used the soft mopping pad to remove the cleaning residue. I washed the mopping pad in the washing machine. Then used that pad again with a gloss finish concrete sealer. I couldn’t find one contractor that could get to the job in a reasonable time. I’m saved literally thousands of dollars and could not be happier with the results. I now use it weekly to mop my floors both in the house and monthly on our finished garage floors. Love this!!

Nice floor machine.

This is a very lightweight scrubbing machine very easy to handle small water tank but good for smaller areas.

Great Customer Service

This is a quality scrubber at a reasonable price. I've ordered several for our organization. I had a faulty vacuum pump on one of our scrubbers, so I called Sunmax, and they were fantastic to work with. They sent out a new pump free of charge and it has been working great!

Great product

Able to see a difference in the spots that have been cleaned with the product (the pads work better than the grout scrubber). It takes little effort to move the product during cleaning. Wish the instructions were a little clearer on some parts of the package.

We have a large home with wood floors.

Bought this buffer for my wife to use. She loves it. Our wood floors are gorgeous since using this buffer. Very happy that I bought it for my wife. Now I do not have to polish floors. Was a good investment for me. When she's happy, I am happy

Good powerful unit for floor cleaning.

This unit has good weight and power to get floors cleaned and buffed. The optional more aggressive pads would have been interesting to try.

A very effective tool

The machine is easy to use and does a great job. I used the brush attachment to strip 20+ years of mop&glo off some kitchen linoleum with zep floor stripper. The job was easy and the results were great. I gave it 4 stars because it's kind of pricey for what it is, an electric motor with a handle.

Sealed hardwood floors can be tricky, but the RT15's gentle touch and soft brushes or pads are perfect. It's a great machine for maintaining the shine and cleanliness of our hotel's wood floors.

This thing works exactly as it's supposed to!

This product was a game-changer for our rough tile floor - it's the first thing that's made a noticeable difference. And with four dogs in the house, it's definitely worth the investment!

Awesome machine to clean but does not SAND .

I began stripping my floor and we were doing it by hand, which was extremely difficult. I decided to purchase the machine and it has saved my back. It’s really powerful and very easy to use and very light weight. It almost goes by itself.I bought the machine to sand my floors after stripping but it does not come with a sanding disk . I have not been able to find a sanding disc to fit the machine. I called the company but they were not much help . I’m very disappointed! it was a very expensive machine and I am sorry I bought it. I don’t recommend it if you want to sand floors !

Great Scrubber…!

We have cement floors in our basement.We tried mopping them, using a scrub brush thing on them, and several other products but either did not hold up to the wear and tear of frequent usage or they just did not work at all.When I was in the Navy we used similar floor scrubbers to clean and polish everything from tile floors to diamond deck flooring on the ships…This is very sturdy and it does a great jog both scrubbing and polishing or cement floor…!One thing I will mention…If you have never used one of these then it take a little getting used to how to operate it.There is a special kind of motion that is used to make it glide back and forth.It’s difficult to explain you just kind of need to feel your way into it.Once you have this mastered, which is not difficult, then it’s very easy to use.I would recommend this to anyone.

Worth every dollar

* I don't often write reviews I read all the reviews across Amazon, Walmart and Homedepot and they were either hit or miss. Every one was happy or its junk..... So I was hesitant to buy this. My wife recently took the lease on a large store that needed lots of help. I talked to the previous tenant who moved 4 stores down, he said they haven't finished the VCT floors since he had been in the shop and he had the lease for 7 years. It was previously a discount cigarette and dollar store. HEAVY foot traffic, with deep embedded stains and ground in dirt. I ordered the machine and pad kit last week and it arrived last night. Although I am not ready to do the floors until this coming weekend, I can't wait to play with new toys. I took it to the shop last night, unboxed it, slapped on the brown scouring pad and went at a couple of the worst spots. Again, this floor hasn't been finished in 7 years, and judging by the condition of the old tenants new store, probably hadn't been mopped either. I used a little powdered Spic an Span with bleach in hot water and did a couple areas roughly 4'x4' just to test. This machine handles great! for everyone saying the "Pad doesn't stay on", make sure the tabs line up between the motor head and backing plate. Turn the machine on, and gently guide the handle, letting the buffer do all the work swinging it side to side at the machines own pace. I worked side to side with overlapping each pass, then turned 90 degree and did the patch again. Mopped up with hot water and GOD DAMN!! I thought we were going to have to replace this floor. I took before and after photos of my spot treatments that I will add later. I will add photos and update my review after I strip and polish the other 3,000 square feet. Once my main floor is done I will move to the basement with the stiff brush head and clean the concrete prior to have the floors painted. That is another sad looking area that I have high hopes for.This unit is small, it will take a little time to do my areas, but to have the ability to strip my floors and then buff them as often as I would like, when ever I would like, with out having to go to home depot to rent a machine makes it worth it. I am also looking forward to be able to try and dry clean wall to wall carpets.
