I ordered the Kenmore 81714 Ultra Plush and it came in today. I gave it quite a workout as I've been vacuuming since it's arrival. The kids and I named it Kenny. This thing is so fun. I started out on the hard floors and it handled it just fine. I wish there was a separate power head with a fluffy brush roll to dust the floors, but I do think the suction on this Kenmore is amazing enough to not need it. This is my first canister and I felt a bit clumsy and clanked it everywhere. I think there's a bit of a learning curve to it, but Kenny followed me wherever I needed to go.Then I switched out the power head for the powered pet brush for the stairs. I do not own pets, but I bought this vacuum specifically for this attachment. My old Shark couldn't suck up the sand out of the carpet that the kids track it. I think the Kenmore handled it like a champ. It was a quite a workout using this attachment as I wanted the suction as high as it would go. There's a place on the handle to adjust the suction level. This would make it easier to maneuver on the stairs, but I didn't want to sacrifice suction. I needed a deep clean after using my Shark for years. Again I was a bit clumsy and knocked Kenny down the stairs, but he held on tightly. The hose took quite a yank, but didn't break. The motor didn't skip a beat. Kenny's wheel popped off but it snapped right back on.I decided to take him for a whirl on the upstairs carpet. We have medium pile carpet. I kept the height level on the lowest one to try to get deeper into the carpet. It didn't make it difficult to push, but I could hear all the dirt and dust that my Shark was missing all these years. I took my time with him. I did have to clean hair, thread, and yarn out of the brush roll. This is not an anti-cutting brush roll like my Shark. I feel like if you take the time to clean out the roll each time you use it (we have 4 girls with long hair), then it won't get too bad.After running Kenny for HOURS on my hard floors, stairs, and carpet we needed a break. He was getting pretty hot. I never smelled anything burning or funny smells, but with how hot the unit was getting, I felt he needed to cool down a bit.Finally, I took him around and used the different attachments for dusting. The machine dusted quite well. The suction on Kenny is AMAZING. I was able to use the dusting tool for the windows, wall, ceiling, baseboards, paneled doors, etc. Then I followed around the perimeter of the rooms with the crevice tool.I'm highly impressed with this vacuum. I'm so glad I bought it. I just hope it lasts and doesn't break on me. I bought the protection plan just in case because things just aren't made like they used to be. At the end of the day, Kenny pulled up an ENTIRE bag of dirt, dust, and sand from deep in my carpets that my Shark was neglecting for the past 4.5 years even with daily vacuuming. Gross. Also, really cool to see that Kenny is performing like I had hoped.I have 2 complaints.#1 how hot Kenny got. I was a little worried for him. I understand it's a 12 amp motor and will put out some heat, but it was hot to the touch and could burn skin. I worry about one of my kids touching or the motor overheating and catching fire or melting plastics. He started getting hot on the stairs so I hadn't been running him that long before I noticed the heat. The hot air blowing from the vacuum made a spot on my leg red because I had to wedge him with my leg so he didn't fall down the stairs again. He's a champ, though.#2 I wish the opening for the crevice tool was slightly larger. I had to keep going over the same areas where the baseboard meets the carpet. I may try to find a larger crevice tool to use instead.
