How Long Do Robot Vacuums Last & How To Extend It

Robot vacuum cleaners have the reputation of breaking after a few years of use, especially for lower-end models. There are different price points available, and quality also varies greatly.

Robot vacuums can work just fine for at least four years with proper maintenance. The cute little cleaners wear out easily compared to their bigger counterparts. Picking the right brand with a better battery and motor for a new purchase would save you money in the long run.

We discuss this topic in more detail in the rest of the article below. If you are a robot vacuum owner looking to buy a new one, read more.

Lifespan of Robot Vacuums and General Maintenance

Robot vacuums can last for around four to six years, provided they are of good quality. It also goes without saying that improper use could damage internal and external components. Each part of the robot vacuum cleaner must be in working condition to achieve the same cleaning efficiency every cleaning time.

Lifespan of Robot Vacuums

Bristle brushes and Rollers

The first part to usually show signs of wearing out in a new robot vacuum is the bristle brush. However, it is inexpensive and fairly easy to replace.

To maximize the usage of bristle brushes, make it a point to inspect them after every use. Remove human hairs and furs if you have pets, and wash them in mild soap and water once a month.

Bristle brushes are generally good for use for at least six months. If buying a new one is not a problem, you can replace them as often as you like.

Rollers may be easier to clean with a simple wipe or wash, especially the rubber ones.

Vacuum filter

If you can visibly see too much dust in the robot vacuum filters, clean them immediately. Blocked filters will reduce the efficiency of the vacuum and may also cause the accumulation of dust inside the device.

Depending on the type of filter, you must replace them every 3 to 6 months. With proper cleaning, you can even use them longer as long as the fibers are intact.

Sensors and Internal components

The sensors must be wiped with a slightly damp melamine foam if a layer of dust begins to cover them. If a sensor fails, the robot vacuum cannot properly detect materials and obstacles.

Whether you like it or not, there will also be dust buildup inside the robot vacuum. If you have sent your robot for repair or battery replacement, request a cleanup to avoid heating components.

The motor component could also fail due to natural wear. They can be replaced by a qualified technician or DIY at home using guides.

We discuss the robot vacuum’s battery and motor in the latter section of this guide.

Base Station and Dustbin

Even if you have a more premium vacuum cleaner, you still need to empty the dustbin. Do it even before it is full to avoid any problem and disruption in the cleaning process.

If it has a dust bag instead, empty it every after use to prevent blockages and overheating.

Similarly, check the contacts of the charging base station every once in a while. If dust has accumulated, carefully wipe the surface with a slightly damp melamine foam or cloth.

Regardless of the brand, proper maintenance goes a long way in ensuring that the robot vacuum will continue to work.

Important Cleaning Routine Before Use of Robot Vacuum

Your cute little robot vacuum is a great assistant for cleaning. With that said, you should still tidy up before sending it to work.

Even though some robot vacuums can mop liquids, it’s better to wipe large spills. Doing so avoids any water damage to internal components and extends the life of your robot vacuum cleaner.

Pick up or quickly swipe the little pieces of trash that you can handle. They are anything other than dust which can lead to broken parts or inefficient cleaning.

Also, properly cover or move power cords away from the way of the robot vacuum cleaner as the protective covering may be damaged.

Above all, make sure you have performed general maintenance the last time before using your robot vacuum again.

Accessories of Robot Vacuum That Need Replacement

Your robot vacuum may work fine, but damaged accessories could mean that cleaning capabilities are not maximized.

  • Side Brush should be replaced as soon as they are worn out. If you do proper maintenance, it could be due in 6 months to a year.
  • Middle Rubber roller brushes may get worn out over time, depending on the frequency of use. Replace them as you deem necessary.
  • Robot Vacuum Filter should be replaced when it’s function get useless, normally around 6 months

Consider replacing accessories that you bought to optimize the cleaning capabilities of your robot vacuum:

  • Boundary tapes must be replaced every five years or as they accidentally get damaged.
  • Vacuum covers that provide aesthetics can be washed as they get dirty or replaced to match the holidays.

Robot Vacuum Components that Age Out

Just like other rechargeable devices, a robot vacuum’s battery and motor component will naturally degrade over time and need replacement.


Rechargeable batteries steadily decrease battery life as they age, even without use. However, overcharging, overheating, and unoptimized charging cycles wear out the battery faster.

The same is true even if you just shove the robot vacuum into a box, never to be opened for months. When in storage, the battery will naturally discharge and could eventually be empty.

It is important to recharge the robot vacuum or any rechargeable appliance before the battery completely runs out.

Battery components of robot vacuums are usually built-in, but they are not impossible to replace. In general, batteries are in good shape for at least two years before you need to swap them out.

Given that other parts of the robot vacuum are intact, a new battery would make your machine good as new.

Robot Vacuum Battery


The motor of any certified robot vacuum cleaner can be expected to work without problems even beyond the warranty period.

If it fails for any reason within the warranty period, send it for repair or replacement.

Suppose the problem with the robot vacuum’s internal motor occurred after the manufacturer’s warranty expired. In that case, you must determine whether to either repair or replace it

The common causes of robot vacuum motors not working are bad components, such as a transistor or diode.

An old robot vacuum may begin to produce “clicks,” give off a smell of burning copper wire, or simply won’t turn on.

It should only be repaired by a qualified technician, who can inform you whether it’s repairable or needs replacement.

Before you spend anything, weigh whether it’s more economical to extend the life of your robot vacuum or finally get a new one.

With proper care, your robot vacuum can last for at least two years, even for low-end models. Internal components and accessories can be replaced to indefinitely extend the lifespan of your cleaning companion.

Proper maintenance after every use and periodically can ensure that the components will work flawlessly next time.
