Question: I have both thick carpets and low pile carpets, plus hardwood floors.  Does this model have a height adjustment?
Document: With no height adjustment, it sinks into the thick carpet and the suction creates a lot of drag and then in reverse, the brushes combine with the suction to make the return trip very difficult. We are slowly trying to eliminate most of our carpet and I'll be glad when its just two bedrooms that need vacuuming.I will add that this thing does a phenomenal job on tile and hardwood. Turn off the brushes and the suction will pick up just about anything.
The lift-off party of this vacuum is fantastic and very handy; however, when the vacuum is fully attached, I found it to be EXCEEDINGLY heavy to push on our carpet. The carpet pile is rather low, not plush and the brush roll sounded extremely harsh on the carpet. I'd be concerned if I had a loop pile. Also, without the brushroll on, this sweeper did a poor job of suctioning hair off of our hardwood floors.
Time to start vacuuming and this is where the minor nitpicks come in.First, the machine is heavier than you would think and it has no height adjustment (I believe it adapts automatically to pile height) so on deep pile carpeting, it can be a workout to vacuum the whole house. It also drags on the return stroke which I presume is the bristles rotating in the direction opposite of the reverse pull.
It's heavy, and very hard to push on even a medium thick carpet, I'm a large male and it weighed on my arm. I don't know why they call it a powerglide, but it does not glide on carpet.2. It seems to be mainly designed for hard floors or very thin commercial floor type carpeting. I could not even run the brush in the back bedroom with the high pile. It does say so in the guide, so at least you've been warned.3.
The first thing I noticed about this vacuum is that it sucks - very well indeed! Our floors had been vacuumed thoroughly on Saturday with my trusty old lightweight upright. When we got this on Tuesday I was excited to try it, and couldn't believe the amount of fur and grit it picked up from carpets that had looked clean.It swivels nicely around furniture legs with good suction edge-to-edge, and the low profile on the front gets under furniture better than my other vacuums.
Best vacuum I've EVER had and so easy to use - turn off brush button (right at your fingertips) and vacuum hard floors, turn button back on vacuum carpets any height and weight....turns and rotates as needed - empties clean & easily - wonderful! Would never buy another kind.
There aren't many things in life you want to suck, but a vacuum is one of them. This Bissell does an excellent job of general vacuuming and pet hair removal.I picked up the Bissell 2763 to test again my current (and its direct competitor)Dirt Devil 70095. In a home with mixed hardwoods, low-pile carpeting, and various Pottery Barn rugs, the Dirt Devil has been a staple for removing golden retriever hair.
It is difficult to use on thick and high carpets. The user has to push it hard in order for machine to move.
THis vacuum was very easy to assemble right out of the box. You only have to put on 3 pieces. The vacuum is not very heavy  The vacuum works very well. I used it in my house and had just vacuumed 5 days earlier and it sucked up quite a bit from my carpet. Their is a setting to switch on the brush movement on the vacuum which makes it easier to go across certain surfaces. Their is no height adjustment it is just set at a standard height.
1 star. I don't write many reviews, the product has to be really great or really bad. This is the latter.This vacuum was like the Hindenburg. It didn't make it through its maiden voyage. I was vacuuming a low pile berber rug and the power brush sucked in the rug, the belt started heating up and stinking of burnt rubber. I figured I could salvage the machine, and after taking off about 6 tightly inserted screws, removed the thread from the brush and reattached the belt.
Answer: IT DOES AUTOMATICALLY.  We have a wheel that squeaked like crazy until I put some WD40 on it.  I don't like it on tile floors as it tends to blow things around.  This is better than what I had before.  I have 4 long haired animals and it does a DECENT job.  Nothing is perfect.
