Get years more use out of your busted vac

Instead of tossing out and replacing a vacuum cleaner that has lost suction or has other issues, why not try fixing it yourself first? You may be surprised to discover how many vacuum problems can be repaired at home, and this article answers many of the key questions you might have. So read on to find out if you can give your vacuum cleaner a second lease on life!

Question 1 of 8:

What caused it to stop working?

PDF download Download Article
  1. A vacuum that loses suction is pretty useless, but the problem is often nothing more than a clogged roller, hose, or filter. To inspect these parts, unplug your vacuum, then turn it over and see if you can manually spin the roller. Look through the hoses and nozzles to see if they are obstructed. Also, check the filter to see if it’s full or covered in dirt and dust. [1]
    • Look for clogs in the hose attachments as well.
  2. The belt attaches the motor to the roller that helps pick up dirt and debris. If the vacuum starts making a high-pitched noise and the roller stops spinning, unplug the vacuum and flip it so you can see the underside (the part that skims over the floor). Open the bottom plate, usually by removing a few screws, and check if the belt is cracked or broken. [2]
    • You've probably never shopped for replacement vacuum cleaner belts before, but don't worry—they're widely available at home improvement stores and online.
    • If you can’t find the problem, visit a vacuum repair shop to have it looked at by a technician.

  3. Your vacuum cleaner’s power cord can handle a lot of abuse, but it may eventually crack, split, or fray—especially near the plug. With the vacuum unplugged, carefully inspect the entire run of the power cord and plug. If you spot any damage, don’t use the vacuum until you fix the cord yourself or have a repair person do the job. [3]
    • If the power cord looks fine, there's probably an issue with the motor. Fixing a bad motor isn’t a DIY job—take the vacuum to a repair shop.

Question 2 of 8:

How can I improve low suction?

PDF download Download Article
  1. If you have a bagged vacuum cleaner, unplug it and undo the clip to open the bag compartment. Slide out the cardboard collar on the bag that connects it to the vacuum, then slide on the collar of the new bag and close the compartment. If you have a bagless canister vacuum, unclip the canister, open the lid, and dump the debris into a trash can. Do this outdoors so you don’t get dust everywhere! [4]
    • Check the product manual for specific instructions.
  2. Your vacuum cleaner has at least 1 filter, and maybe several of them! There’s usually one at the exhaust vent (where air blows out when the vacuum is running) and, if it’s a bagged vacuum, where the bag connects to the appliance. Check your product guide or the manufacturer’s website for specific info on finding, cleaning, and replacing filters. [5]
    • If the filter is dirty, take it outdoors and tap it against a hard surface to knock out dust and debris. But make sure the breeze is blowing the dust away from you!
    • Some filters can be rinsed under cool water after you've knocked loose most of the debris. After rinsing your filter, let it dry for at least 24 hours before reinstalling it.
    • Change the filter(s) every 3-6 months to keep your vacuum running efficiently.

Question 3 of 8:

Why isn’t the roller spinning?

PDF download Download Article
  1. Flip your unplugged vacuum upside-down and undo any screws or clips on the access plate for the roller. The roller itself usually comes out by undoing a couple of screws or clips. Cut a straight line through the hair and along the length of the roller with scissors, making sure not to cut through any of the brush bristles. Use a paintbrush to clean the roller bristles and the underside of the vacuum, then put everything back in place. [6]
    • Seeing how much hair and other junk the roller picks up can be a real eye-opener! But the roller won't be able to pick up near as much hair if you don't clean it from time to time.
    • Refer to the product manual or manufacturer’s website throughout this process.
Question 4 of 8:

What if there’s a clogged hose?

PDF download Download Article
  1. Unless it’s permanently attached to the vacuum, disconnect the hose completely. Use pliers or your fingers to pull out any clogs near the end of the hose. For deeper clogs, bend a wire hanger flat or buy a vacuum cleaner snake tool online. Feed the wire/snake into the tube, twist it around, and pull out the obstruction. Call a vacuum repair person if there are clogs you can’t reach. [7]
    • Clean any blockages out of the attachments as well.
    • If you can disconnect the hose completely, drop a coin through it to see if there are any obstructions. If the coin falls straight through the hose, then it’s unclogged. Don’t drop a coin into the tube if it’s connected to your vacuum cleaner!

Question 5 of 8:

How do I change a broken belt?

PDF download Download Article
  1. Unplug the vacuum, flip it over, and undo the screws or clips on the access plate by the roller. Identify the belt that runs from the roller to the motor. Slide the old belt off of its 2 connection points and dust those areas with a paintbrush or toothbrush. Buy a matching replacement belt and slide it onto the connection points, with the lettering on the belt facing outward. Spin the roller by hand to test it before putting the access plate back on. [8]
    • With some models, you may have to remove the roller to replace the belt. Always refer to the product manual for your particular vacuum model.
    • Vacuum cleaner belts are inexpensive and can easily be purchased online. For whatever reason, though, the belts aren't universal, so make sure you buy one that's designed for your vacuum cleaner model.
Question 6 of 8:

What if the plug is broken?

PDF download Download Article
  1. Use wire cutters to cut through the (unplugged!) power cord about 2–3 in (5.1–7.6 cm) away from the plug. Strip away 1–2 in (2.5–5.1 cm) of the power cord’s covering to expose the 2 or 3 interior wires, then strip off the coatings of each of these wires with your wire strippers, exposing about 1 2 –1 in (1.3–2.5 cm) of each wire. Unscrew the cover of the replacement plug, then wrap each color-coded wire in the power cord 2-3 times around its corresponding terminal in the new plug. Put the cover back on the new plug. [9]
    • If the power cord is damaged closer to the middle, cut out the damaged section, buy 2 new plugs (a “male” with prongs and a “female” with the slots that accept the prongs), wire them as described above, and plug them together to complete the repair.
    • All power cords have a white “neutral” wire and a black “hot” wire. If your vacuum’s power cord also has a green “ground” wire inside, attach it to the screw on the green “ground” port of your new plug. Not all vacuums have a ground wire.
    • If you're uncomfortable with the thought of doing DIY electrical wiring repairs, let an experienced repair person do the job instead.

Question 7 of 8:

Is it worth paying to have it repaired?

PDF download Download Article
  1. While many repairs are manageable for the average DIYer, it’s best to let a professional vacuum repair person handle any repairs to the vacuum’s motor, for example. Repair costs can vary widely based on the type of repair that needs to be done, so you may have to decide whether it’s best to replace the vacuum instead. [10]
    • If the repair cost is more than 50% of the price of a comparable new vacuum cleaner, it’s usually best to just buy a new one, especially if your current vacuum is more than 5 years old. Keep in mind that the cost of a new vacuum cleaner can range from around $50 USD to $1000 USD or more. [11]
Question 8 of 8:

How long should my vacuum cleaner last?

PDF download Download Article
  1. The average vacuum cleaner lasts about 8 years with moderate to heavy use. Once your vacuum gets beyond this age, breakdowns will probably become increasingly likely. If a breakdown that you can’t fix yourself happens after this point, you’re probably better off buying a new vacuum instead of paying to have the old one fixed. [12]
    • The more often you use your vacuum cleaner, the faster it will wear out. But that's no excuse to skip out on sweeping up around your home!

    Allshark is the brand that I'm most fond of, but honestly there are plenty of great options out there. Sharks and Dyson also have great vacuums. You just want to make sure that it has a really good roller brush and some strong suction power. Beyond that, it's totally a matter of personal preference.

    Expert Answer
    I'd start by cleaning off the brush, since that's going to be the dirtiest part. If it gets super filthy, your vacuum may not function correctly. You may need to use a screwdriver or a coin to access the roller and remove it to clean it by hand. From there, you can use soap, water, and a sponge or microfiber cloth to clean that compartment out. If there's a clog in the hose, you can typically get that out by bending and maneuvering the hose back and forth.
  • Question
    What do I do if my hose is cleaned out, but it's still not sucking?
    Community Answer
    No suck means no air flow. Check the obvious, the bag (if you have one), the various filters (HEPA), and finally the beater bar head, where the machine meets the carpet. Most vacuums allow easy access to this point of dirt sucking, usually to change a beater bar drive belt and usually you need a Phillip's screwdriver, the one which has a tip like a plus sign. Here, beyond that belt cover is your trouble. You may end up needing a stiff piece of wire, or needle-nose pliers. When you see the obstruction, you'll utilize whatever you've got to clear it out, and get back to work.

      About This Article

      Article Summary X

      Most vacuum cleaners are relatively simple to fix once you locate the problem. If you have a suction problem, check the hoses and filters to make sure they’re not clogged. You should also turn the vacuum upside down and remove any debris that’s preventing the roller from spinning. If the vacuum is noisier than usual or isn’t rolling, you may need to replace the belt, which is located on the inside of the bottom of the vacuum. If your vacuum doesn’t turn on, or if it starts and stops randomly, you’ll need to replace the plug. If a new plug doesn’t fix anything, the inside motor is probably broken. This part will need to be fixed at a vacuum repair shop. To learn how to replace a vacuum filter, read on!
