The shoulder straps are also made with 5mm EVA foam and feature quick-access and water bottle mesh pockets for each strap.

Materials and Build Quality
The RB36 backpack is made with high-quality materials, including Challenge UltraWeave™ 200 fabric, Ultra Stretch™ Mesh, and Tie-Dyed Nylon with a PU-Coating, which are ideal for fastpacking.

The UltraWeave™ is constructed with an optimal blend of UHMWPE & high-tenacity polyester. The tight weave is laminated with an eco-friendly adhesive to our revolutionary Challenge RUV™ film. The result is a textile that is incredibly strong, lightweight, and waterproof to 200 psi.

ULTRA™ performs in the harshest environments, in both sub-zero and tropical climates. The Ultra Stretch™ Mesh combines Ultra(UHMWPE) fibers with Nylon6-6 and spandex, providing exceptional flexibility.

Awesome robo-vac/mop with rotating mop head/no pads.
Size: E25 Black
I owned a Narwal Freo for 1 year and it died right after the warranty period was up. Tried replacing the battery but that did not fix the issue so I had to purchase another one. I noticed this eufy had high reviews and the 1 star reviews seemed to be just isolated issues so I purchased this one. Right away I noticed that the instructions/setup was much more simple. Second this one has a big wide mop roller on the front and after mopping I didn't see the mop streaks in circular patterns on the floor like I did with the Narwal as it had two rotating mop heads on the front so the single mop roller seems to be a better solution. Setup consisted of removing protective wrappers off of the tanks and base station, filling up the clean water tank, installing the detergent bottle and plugging it in. Next I downloaded the app and connecting the vac/mop to my network. This was SIMPLE to say the least. From there I could have just clicked clean on the app and it would clean the entire house. However, mapping gives you more flexibility when planning your cleaning ritual. You can define no go zones and clean rooms in any order you choose. I have a shedding dog so I have a separate robovac to clean up the dog hair prior to vac/mopping. This is a MUST with any robovac/mop combo as the dog hair on the floor will mix with the water and detergent and eventually prevent the mop from doing a good job. It will make a mess in the bottom tray of the base station too. I learned this through experience and reading all the one star reviews from customers. Robovac only cleaners last a LONG time. I had one that is still working great for over 3 years. All I had to do was replace the battery so it doesn't have to pause the job to recharge. So the mapping only took 4 minutes and it was pretty accurate. After the mapping I defined the room boundaries and renamed the rooms. Next I sent it off to clean and it did a FABULOUS JOB! No streaks and the floors are clean. The noise level is really low and more quiet than the Narwal. The other thing I noticed is it didn't use up much water to rinse the mop while cleaning. The Narwal used a lot of water and I was always dumping dirty water and adding fresh. I will always have a robomop and robovac as they save me so much time by not having to do this job twice a week. Connectivity to my network is excellent as it's in a location far from the router. This vac/mop is a good value for the money if IT LASTS BEYOND 1 YEAR. I will update this review as necessary and if it fails right after the warranty period I will report and downgrade this review to 1 star. These companies need to learn the importance of reliability and correct these issues. When I first reviewed the NARWAL it had almost a perfect 5 star review from all customers. After the year was up and it failed that star rating went down to 3+ stars. Most reviews reported their robovac/mop just died like mine did after the warranty period. I downgraded my review and reported the issue. I'm hoping this one will last because at the moment I am VERY satisfied with it like most customers. This model has been on the market much longer at the time of purchase so I would suspect if there were any reliability flaws they would have been addressed and corrected by now. We shall see. At this time I highly recommend!!

Excellent Robot Vacuum, Especially for the Price
Size: 11S, Size: 11S
I have been an iRobot Roomba buyer since 2007. My last Roomba bit the dust this month, and I did a ton of research before buying a replacement. I went with the Eufy for a few reasons: price point, cleaning power, quietness, and sleek design. Price: Very reasonable. Almost reasonable enough that I'd consider getting another one for my second floor. For now I'll just carry it upstairs. Cleaning power: This thing sucks... It's suction is much stronger than my Roombas have had. It picks up so much dust and pet hair. We do a full vacuum every other week with my Dyson, so I think of the robot vacuum as a supplemental vacuum. I was shocked at how much was in the dustbin after it's inaugural cleaning! The picture attached to this is from that cleaning. It also gets a ton of dust in the little dust filter. In one of the video reviews I watched, the reviewer said it didn't pick up anything in that dust filter... So maybe my carpet is particularly dusty, because it has a thick layer after each cleaning. Quietness: I work from my home office, and this thing is quiet enough that I don't even turn it off during conference calls. This might be the thing I am most impressed with. My last Roomba was LOUD-- you couldn't even have a conversation with someone in the same room, let alone someone on speakerphone. Sleek design: I love/hate this. It definitely looks modern and cool, and more like an art piece than an appliance, but it shows all my finger prints, and now I keep a glasses cleaning cloth nearby so I can rub it down. I suppose if I only use the remote and never pick it up, this won't be an issue. A few considerations: I was hoping to find a robot vacuum that wouldn't eat my carpets' tassels, but I don't think that vacuum exists. I have only used the Eufy 4 times so far, and it doesn't always get its brushes wrapped around the long tassels, but it does sometimes. It seems to realize it sooner than my Roomba did at least. The Roomba would sometimes rip gobs of them off in a single cleaning. I try to tuck them under the edge of the rug and that doesn't seem to bother Eufy. It has pulled off probably 2 tassels so far. The cleaning pattern seems pretty random. I saw some other vacuums that chart out complex maps of your home, and Eufy doesn't seem to do that. But, it doesn't seem to matter, because it still hits every spot in the rooms. I'm a little concerned about durability. My Roombas ran for many, many years with easily replaceable parts. We'll have to see if Eufy has the same longevity. All in all- I'm very happy with my purchase and definitely recommend it!
