Question: How do you take the head apart is there a trick doesnt seem to come apart and I think somethiong is stuck in end of hose
Document: Also, it has a feature where you push a button and the cord gets drawn back inside the machine, but it doesn't work properly; it seems to lack power, cuz it pulls the cord partway in and stops, then a bit more and stops, and you may have to push the button as many as 5 times. Come to think of it, I should check the machine to see if it has a union membership ID number, cuz it certainly has the work ethic.
If I were still living in a carpeted apartment, this would be THE best canister vacuum in the world. The powered brush head is excellent, and has the best suction on a canister I've ever seen.But once you take off the powered head, all that suction is gone. I'm using the hard floor tool on our hardwood floor, which has little cracks in it where dust loves to hang out, and it can't get any of it.
The vacuum is light and so powerful that the brush head propels itself along.The attachment piece for hard floors is very effective and cleans all the edges and corners in my kitchen.Some things I don't like about the vacuum:The hard floor attachment tool storage on the canister. It is a well constructed and durable way to store the large attachment, but the location is poorly thought out. I find it annoying that I need to take it off anytime I want to use the vacuum to clean anything.
This is the worst vacuum I have ever owned. The hose is too long and the cord is too short. It is very difficult to change the power  head and remove the hose from the pole.
I have had this vac for about 4  mos. I wish I had done some research. Suction with the power head is good but w/o it, just using the hose and tools, it's pretty wimpy. My biggest complaint though is how frequently I have to empty the dust cup AND clean the filter.
After a couple of days comparing, we picked this unit. We are totally happy we did. It came doubled boxed. It was very simple to put together and it cleans wonderfully like a unit costing more. I see why some might complain about the hose binding it does not have a swivel because for the power head, if engineered with a swivel would be more $$. Easy to use, empty and clean.
My requirements -  a Bagless Canister Vacuum with a 12 Amp rating in the $150 range. With price in mind, I gave this Vac an overall rating of 4 stars. I thought the machine in general works well.Comments:Has an electric-motor carpet power-head with on/off  &#8211; not one run by the hose vacuum itself.
When the power head is locked upright, it blocks the suction and the motor revs up, odd design. It is admirable for a bagless, and I'm used to emptying it after each floor. The hose does kink easily and the on-board attachments fall off ALL the time so they're best left behind - kind of defeats their purpose. Lastly since I have hardwood and rugs, I'm always swapping out the hard wood floor brush with the power head.So back it goes.
Absolutely love this vac. In fact, I vac more often than I did before. It sucked up stuff out of my carpet making think that my Hoover windtunnel stopped working a long time ago and did not tell me. Price was wonderful for such a strong and effecient vacuum. Some people complained about the tool caddy but I do not have my tools in it and the pole wants to spin to the left while using it - no big deal just adapt.
If I had the proper tool I'd take it off. For the $$ spent this is a good value IMO.
Answer: The hose on mine became so impacted with carpet fuzz that I had to cut a coat hanger and bend a small hook on one end use it to fish the debree out of the hose, but be careful, as a wire runs through there as well and I could easily see a novice "coat hanger fisherman" breaking the electrical wire that runs down to the head. If you need to open the head, there are four screws on the bottom. Before doing all that, make sure that the dust bin and filter are clear, there is one small passage in the bin that was also impacted, and I had to use a screw driver to dig it out. This is a very quite and efficient vacuum, but emptying the dust bin and cleaning the filter is very messy business. If I ever need a new vacuum, I think I shall go back to using bags. Good Luck: Mike
