CO-Z 20 Inch Pressure Surface Cleaner with Wheels, Dual Handle Stainless Steel Housing Circular Power Washer Attachment, 4000psi Driveway Concrete Cleaning Scrubber Accessory for Gas & Electric Washer

I have a Dewalt 3800 PSI 3.5 GPM pressure washer in great condition with great pressure which I used, but I was really skeptical of this contraption to work and was ready to send it back at the first evidence of it not being worth the price tag or not being equal in terms of cleaning vs my pressure washer with its basic nozzles which take forever but clean excellent..This worked absolutely excellent in terms of cleaning and ease of using it..The last time I cleaned my 4000 sq.ft. driveway it took me 3 days, inch by inch with a reasonable width nozzle. When I was done with that PITA job I felt like I rode a bull in a rodeo; hands ached, back ached, neck ached, headache you get the picture. This time I used this "surface cleaner" to do the driveway and a porch in addition to it in a total time frame of just 2-1/2 hours! They both came clean without streaks but of course you need to do the conventional nozzle for the corners which is no problem. Best thing is all the water is contained under the unit and for the first time I didn't need to wear my Muck boots to do the job as I watched the dirt just flow down hill. Went over it a second time to see if anything remained and nothing..I definitely recommend this and it should be great to use it to just maintain the drive and deck every month with this as it was so much easier to do this god forsaken job now..All hook ups were easy and the unit is stainless with what appears to be a good design. My unit was smooth with no vibration and was effortless to move around on these castors it has. You have to remember the arms under neath are spinning with pressure so you can't let them hit anything or it will probably knock it out of wack for good like a mower blade so no obstacles and don't go off the edge of the drive way or deck with it. Came with replacement nozzles and o-rings. If it pukes out soon I'll write a update as of this one dated 08/21-23...

Works well. Obviously not as well as the wand in bad spots. However, for light to medium duty work it saved me hours upon hours. Very happy with it overall. If you have a large area like a driveway or large patio this item is a must. Gets hung up periodically but smooth most of the time. Not enough to buy one with wheels attached.

This unit works well with my 3100psi power washer. It obviously does not clean concrete as well as using the wand with the white fan tip in 3” swaths. My concrete has never been professionally cleaned and was very dirty though so this will make keeping it clean a lot quicker after an initial deep clean.

I have a lot of concrete. My driveway is five hundred feet long with two huge turnaround areas. The Pool Deck and Patio is another 1200 square feet. Pressure washing is a three-day event every year. I bought this to save time and eliminate the streaks and my aching back. Two out of three accomplished. It cleans much better than swinging the wand back and forth. My back was not nearly as sore as it usually is. But, I can't say it saved any time. The drawback is you can't really rinse with it because no matter how you roll, dirty water continues to flow out 360 degrees around the path. I went over the same areas 5, 6, 7 times and I still pushed around dirty water. So, I switched over to the wand and rinsed, then back to the surface cleaner, repeatedly. Suggestion: It would be great if someone would modify a surface cleaner with a second trigger handle and a third nozzle on the front. Then you could clean and switch to rinse without changing from the surface cleaner to a wand. Send me a test unit when you get it done and I'll review it for you!

This unit glides over the concrete effortlessly. My washer is 4200 PSI at 4 gallons per minute and it did great.

When it was new, it did a pretty good job with a 3200 psi power washer but quit working. I followed the instructions replaced nozzles and seals as indicated in the manual but this didn’t work. It is also a red flag when A business provides extra seals. Save yourself money and a headache and buy from a known reputable manufacturer

The media could not be loaded. Works great for the price compared to other models that are a few hundred dollars more. Easy to assemble and use. It rolls well with the casters, we shall see how they hold up. I do recommend rinsing the entire surface cleaner with fresh water afterwards. Especially underneath and all around the casters etc. This will help keep the SH from rusting your cleaner. Side note for those looking at the video and photo: I am running this cleaner with a 3,600 PSi 2.5 GPM pressure washer by Simpson. Results may vary if you put it on a weaker pressure washer with lower GPM!

This was definitely a game changer in cleaning concrete decks
