Hose has low suction

The hose has a very low suction in it, but the floor portion seems to work just fine. I have looked for blockages and have replaced the filters with no luck. Does anyone know what is going on?

    The vacuum has little to no suction at all. I took the vacuum apart and cleaned it. The belt seems fine and the roller is spinning. Any suggestions as to what might be wrong?

I too had the same problem for over a year and changed all filters, checked for clogs, etc, but refused to give up. It just didn't make sense that suction was great on bottom but not on toos... I finally discovered that the "door" on the angle hose was not closing properly when the vacuum was in the upright position (if you look at the vacuum from the back, this hose connects the back to the bottom of the vacuum and it has a "door" at the very bottom end that is supposed to block suction to the lower part of the vacuum while upright) It was unable to close all the way because there was a build up of linty stuff in one corner. The best way to access this is to remove the two screws on the clamp found at the top of the hose, (freeing the hose on top only), straighten hose so you can see inside to the end, and watch inside as you press the upright release lever. (awkward, but worth the effort) You should be able to see the door move -it should be completely open when the vacuum is not locked upright, and should be completely closed when upright. Remove anything that might be preventing it from closing - I used a flathead screwdriver. Dont mean to go on and on, but am so excited to have fixed this problem, and have found so many people with the same situation on the internet while trying to find a solution...Hope this helps someone!!!!

Mac, I was trying to follow your excellent directions cleaning in interior trap door that is opened and closed with activation of the foot switch that lowers the handle when I stumbled on an easier step. The foot-long hose that must be straightened to visualize the trap door, can be removed with a couple of counter intuitive screws to the right, not the left as one would think. Once you get that rascally hose off removing the "linty stuff" is easier. I used a long piece of bailing wire with a loop. Thanks, I would have never found that door.

If you have suction at the hose end, then the problem is down below. Belt may be slipping underload, they stretch and give you problems. The dirt inlet from where the hose plugs into and by the brush roll is clogged. There also is a valve that may have broken, you have to remove the top cover to get to it, #53 on the pix.

Eureka Optima Lightweight suction weak on bare floor, hose only works when dial is turn to floor?


I think it is normal. My favorite setting is the dial is turned to bare floor. If you set your vacuum to hose, then you need to adjust the height (do not set the dial to the bare floor).

check the suction hose where it bends down to the floor unit,, lots of times dirt,hair and stuff collects there when the filter was plugged up. remove the floor plate ( like you were going to change the belt ) and use a wire coat hanger to run up the suction hose and back out and clean out any debris, also check the entire hose for blockage ( top to bottom ). if this is all clear and you still have little suction - then the problem could be the vacume motor itself and you will need to take the unit into the repair shop and have the motor rebuilt or replaced.

Hi my dyson dc18 has great suction from wand but when you got to use the vac for floors little suction but wand still got suction even while vacuming floors is it suposed to stop suction from wand


My Dyson dc18 had the same symptoms. The wand worked well and the floor bar had no suction. After removing pieces & shoving my fingers into the machine (no blockage) I found the suction pipe rotates between two positions (floor and wand). It looks like a piece of plastic broke on the outside housing, so it no longer rotates positions when the wheels are raised or lowered. My son found we can move the suction by sliding a finger into the mechanism behind the wheel cover, and rotating the plastic piece clock-wise or counter clock-wise until it locks into position. It's a big pain but it works for now. I wish I could find a replacement piece online. Patty

No suction


well, it actually sounds like there is a blockage. Try removing your hose and dropping something through it, like a quqrter. If it comes through, no clog. If it is clogged, I believe that machine has a blower on the upper part of the cleaner (maybe in the bag compartment towards the top. You can take out the filter holder and plug the hose in there and run the unit . Does the blockage come out? If not, Try shaking the hose, or you can put a stiff wire in it to try to free it. Do not run water through it. If there is no blockage at all, then you will probably need to take it to a service center. But I am pretty confident that we are looking at a clog situation. Let me know if this fixesya! Thanks, Rene (vacuum Doctor)

Sounds like you have two separate problems here.  If the brush bar does not rotate, probably the belt is broken. This is easily replaced, but you need to be precise about which model you've got so you get the right belt.
Loss of suction is due either to a blockage or, quite often, to a split in the short length of clear plastic hose that leads back from the brush bar enclosure.  Repair is possible but replacement is better.

I have a u3450 1500w hoover, suction on hose works fine, but carpet suction has never worked, how can i fix this?


There must be a restriction or blockage in the carpet suction pipe. Look at the port where the hose connects to the machine and check for any accumulation of debris or blockage. The same motor drives both suction inlets so it can only be that there is an obstruction.

Willnt pick up good...


I had this problem once too. When the hose is inserted into the vacuum, the floor unit (where the spinning brushes are) becomes the head of the vacuum. In other words, the suction goes through the floor part and then up through the hose and into the vacuum. If the suction is good when the hose is out, the the problem is blockage at the bottom piece. Take the cover off of the rollers (it is one screw then it pops right off) and see if there is a bunch of lint/hair/gunk blocking the suction hole. You could also take the hose part out of the vacuum and look down the empty shaft with a flashlight and see if you see anything there. Hope this helps!
