My gutters are between 1 and 3 stories high and I've used Gutter Sense for a few years now, along with a 30 ft Mr. LongArm pole. It can be difficult, dirty, and sometimes slow, but there is no better way to clean your gutters from the ground than this.

It works surprisingly well, at least once you get the hang of it. It can be quite challenging at first, so it does take some patience and practice. It's best to learn with gutters at 1-story before you start cleaning gutters 2-3 stories up.

I still have a company out once a year to get up on the roof and do a more thorough cleaning of the gutters. But having Gutter Sense means I only need them to do that once rather than twice a year, saving a couple hundred dollars every year.

I'm on my second Gutter Sense. On the first one, the fishing line managed to slice through the plastic. Now I understand that lubricating the points of contact helps to prevent that. I do wish that Gutter Sense was available in a little bit tougher package, but as it is, it gets the job done, and at around $30-$35 the price is fair. I've tried other means of gutter cleaning, but haven't found any as effective and safe as this.

So, I purchased one of these to clean about a year of accumulated pine straw from my gutters and once I learned to use it it has done a surprisingly good job. It can be a bit cumbersome and can wear on you so I've just been using it about 15 minutes per day, slowly clearing away the debris from my gutters. I took the advice of another reviewer and set the extension pole near my chest and sometimes my thigh, which I can lift as I squeeze the tongs together and remove the debris fairly quickly this way. With saturated and broken down pine straw the debris can almost be rolled out when you have a good grip of it, but you'll have to stop at the gutter supports and work around those. At first I wasn't sure about this product, but after learning to use it I'm glad I bought it and it's saved me a lot of money not having to call someone to do this for me. I did already have a good 18ft extension pole (Unger brand, about $40) which I use for washing the second story windows and this tool has worked very well on it. Since it's made of plastic I doubt it will last very long, that's the biggest downside and after using this thing I'd be willing to pay more for a higher quality materials version.

Decided to invest in this leaf grabber and an extra long pole as an alternative to paying $300 per cleaning using a service. Carefully read the reviews in case this was better than the 3.7 star average suggested. Really pleased with the ease of use and ability to remove dry leaves and partially degraded clumps from my gutters two stories up.
Though the rope was too short, I used some 60 pound fishing line to extend it to the bottom of the pole. Wrapped it around a wooden block at the bottom to make it easier to use (fishing line is a bit narrow and uncomfortable otherwise). I just grip the block and pull it down to operate the grabber.
It took me about two minutes to master use of this leaf grabber tool, and about fifteen minutes before I decided how best to handle the gutter supports which are not viewable from below. I use the fully open grabber to push leaves away from the screw supports and then grab the leaves in the adjacent space. Easy to pick up many dry leaves per go, and effective at picking up large clumps of degraded leaf debris at the bottom of the gutters. Completed one section of about 25 feet in about 30 minutes, and with more experience, an equivalent section in about 15 minutes. Removed about 5-6 cubic feet of leaf matter.
A couple caveats about my success: first, six inch gutters give plenty of room to grab leaves, and second, the leaves are narrow/oblong (Zelcova tree). Will try this on maple leaves on the other side of my house in a few days and update if there is any difference. (See edit below).
All in all, really happy with this purchase, and would recommend, especially for people with wider gutters like ours.

Edit: Was slow in moving around the house using this tool to clean gutters and discovered a few benefits. First it works well when trying to unplug a downspout during a downpour. Two decent grabs of wet mulch-like debris, and the downspout cleared. Excess water spilling out of the downspout brought with it even more debris. After several dry days I again used this on the front of my house to remove maple leaf debris, and it worked equally well as in the back with the Zelcove leaves. Have decided to adjust pole length sufficient to rest it on my upper thigh, which allows for decent fatigue-free cleaning. Having experienced a major downpour several days back, I revisited areas adjacent to downspouts previously cleared and found more debris had been swept close to the downspouts that needed removal. By this, I only need clean this area on a more regular basis, because the further away I go from the downspout, the lesser the leaf accumulation. Basically nothing about six feet or more on either side. Based on this experience I plan to use this every couple weeks during autumn starting when leaves begin to fall and ending when there is nothing left to remove. Not shooting for perfection and allowing the rain to gather the leaf debris near to the downspouts seems to work best. Have to believe that my six inch gutters play a positive role in this process in allowing the leaves to be swept towards the downspouts.
Final verdict: super pleased with this purchase and looking forward to ladder-free, cheap gutter cleaning moving forward.

Once you get the hang of it, it works well. I actually had to tie on another length of string. This was on a 25' pole! It is nice that you can adjust the angle of the head for working at different angles. (I worked from the ground AND leaning out a second floor window) My neighbor saw me using it and he even borrowed it. Worked well for him too. At first I thought it a bit pricey, but after using it, I think it is worth it. I can see where it can be fragile. Be careful. If this were made of aluminum or cheap metal it would DEFINITELY be a way better product.

Takes a little time to get the hang of using it, but once you establish a rhythm you can go, go, go! All you need is a light weight extension pole and you are ready!
