To clean the hose, run a cleaning cloth through it when the central vacuum is turned on. Then repeat this at each outlet to make sure the entire system gets cleaned. Cleaning cloths should be available through your local central vacuum dealer. Even if you don`t see any clogging, it`s good practice to clean the hoses.
Check central vac power unit gaskets and for cracks in housing. Verify the correct voltage is going to power unit. There should be a compliance label on the unit specifying the proper voltage, among other details, such as model and serial numbers. Check for loose wires and a loose motor.
Clog located in the vacuum hose

Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.

Clean or replace the filter. A clogged filter will restrict the air flow, meaning there may not be enough suction to pick up dust and dirt. A simple filter change might be all your vacuum needs. Your vacuum should be cleaned every so often, as well.
Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly. If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.
If there is a clog in the vacuum, you won`t have good suction and the vacuum won`t work. The clog can be in the vacuum head, the hose or where the hose meets the actual vacuum.
Generally, the vacuum hoses on your vehicle are made from rubber and are supposed to last for a lifetime. The rough conditions that exist under the hood of your vehicle usually lead to these rubber hoses becoming damaged over time.

I have a residential hayden super vac the green light on the hose changes to red on some outlets. the hose makes a great deal of noise on some outlets and is quiet on others. what does the red/green light signify? how can i get the vac to be quieter?
ANSWER : On the outlet that turns red, you need to reverse the low voltage leads on the wall outlet.

I have a Roomba 560 (it’s still in warranty !!) and, after my summer vacation, it has a problem.
When I’m charging Roomba, the orange light blinks (and this is normal!) but this orange blinking continues forever…. the light doesn’t change to green.
If I detach Roomba from the charger, the light become green and it works normally until the light changes to red and I have to charge it again.



ANSWER : The problem is not with the charger itself but it is with the battery inside the Roomba. It sunds like one or more of the cells has gone bad so its not holding the same charge as it did. I would recomend sending it in while the warranty is still valid so they will replace it. Your charger and the Roomba itself should be fine.

A few tips to keep the battery working longer:
Only charge the battery when it is drained all the way to zero. It will help keep the battery active.

Only charge the battery until it is full and then disconect it from the power source. It will keep it active longer plus it will help keep your electric bill down.

No Suction I get great suction in the hose, but when I plug the hose back into the unit, there is no suction and the air flow indicator line goes completely red. I've changed the bag and filters. I took the small panel off the back and made sure there is no clog, and took the hose off to make sure there was no clog there. Still no suction. Please help.
ANSWER : I about to say that’s always a clog of some sort that causes that

When I flip the switch on my sebo x1 upright, a red light comes to the brush and bag icons. However, I cleaned out the hose and checked to make sure there is no obstruction from the brush to the hose also, or from the hose to the bag. It is clear that juice is coming to the vacuum, but there is no sign of life except the two red lights.
ANSWER : Thanks for contacting fixya. You should pull out the bag and reset the machine. You should take all the user replaceable items. And turn it on. You will get lot of errors. Then turn the machine off. Put back all the accessories and the bag. Turn you machine on. This will solve your problem.

Hooked everything up per directions. I plugged it in to the closest electrical outlet and nothing happened. The lights did not light up, the connected wall control and sensors leds do not light up. It appears the unit doesn’t have power. The electrical outlet socket is fine as everything else I plug into it works fine. I have tried every other electrical outlet available. The unit won’t power on from any outlet, and all of those outlets run other things, like power tools an refrigerators
ANSWER : Dear Davehibshman,

Firstly; dismantle the plug and replace the fuse with the same rating as the one you have just taken out. Replace the plug cover, put the plug into the socket and try again. If this doesnt work, there may be a problem with the internal fuse (if one is fitted). Two choices here, either refer this unit to a qualified service personnel/ the place where you got it from, or do the job yourself (which will save you a whole bunch of cash). In your circumstances, I would take it back to the place you got it and ask them to put the fault right, or replace the unit completely; if it is past its warranty or guarantee time, then get back to me with a make and model number of the unit, and I will give you step-by-step instructions on how to solve this.

Yours sincerely


I was vacuuming and noticed that the bag needed changing. the red light with the ! inside the triangle also came on. When the bag was changed, the vacuum would not restart. The red light came on. Tried the reset button but nothing happened. Tried unplugging and re-plugging in and nothing happened. Replaced all the filters and still it wouldh’t start. So I brought it downstairs and tried one more time to get it to start. it worked! Is there something wrong with the vacuum cleaner? Was it overheat
ANSWER : It was overheated that is why it worked downstairs after cooling off.

I have the IROBOT discovery that just got a new battery. IT ran great! As the battery was dying, I put it into the home base. The “brick” is green, the home base has two green lights and the on/off pulsates red. It never charges though. Eventually the red light stops pulsating. Customer service said to reset it, clean the metal, and nothing works! They told me to just buy another one. The problem is that I know it was working! Help!
ANSWER : The best thing that you can do is take the charger into somewhere that can test it for the proper output voltage. It should be somewhere very close to 22 volts with no fluctuation. The charger is the easiest thing to test in this case.
