[This review was collected as part of a promotion.] This made cleaning my concrete porch and driveway, much easier and quicker. If you follow the directions, it's easy to use and works wonderfully.

What size are the plastic nuts holding the swivel and the spray head together so I can replace them with metal one's? The unit keeps coming apart because you can't tighten the plastic nuts

I bought this earlier this summer. Seems to clean better than other brands except for needing to stop every 20 mins to tighten the plastic nuts. Does Karcher have a recommended fix for this annoying problem?

[This review was collected as part of a promotion.] Was able to do alot of cleaning with this power washer attachment, was nice to see that it fit on most gas powered power washers, I find it works really well on concrete along with wooden decks.

I cannot believe how easy this is to attach and use. Feels like it is floating on air. I cleaned my 12 x 12 tiled patio, including grout, in 15 minutes. Used to take me over an hour. Driveway is next.

One full day with good performance. Jet got clogged and vibration increased but that was because I kept switching between this and a traditional nozzle and must have slipped some dirt in.

I have a Karcher pressure cleaner, so it was a no brainer to get their surface cleaner. Walmart had the best price and two day to my house delivery. Tried it once since receiving it and it worked great. Saves time and water, no streaking.

I borrowed my son-in-laws just to see if it worked. Boy does it ever so I purchased my own. Super easy to use and it did a wonderful job. Be sure to have an extra garden hose available to rinse the remaining loose gunk away after cleaning an area.

Works great, a good 12 inches per pass. On really hard places, just slow down. Took 15 minutes to do 2 hours of work. Easy to handle and guide. You still have to wash up the cleaning mess but otherwise, feet stay dry.

This was the best thing I bought in a long time. It cut the time on my drive in less then half. Its light and very well made. Has a brush you could replace. Fast shipping ...you want to make your surface clean with ease. Buy this product. Thank you.
