3. Eufy by Anker Boostiq Robovac 11s

Best Budget Pick

Eufy by Anker Boostiq Robovac 11s

The Boostiq Robovac 11s is a simple robot vacuum cleaner that does exactly what it sets out to do — pick up dust, dirt, human and pet hair, crumbs and the like.

The sleek design allows it to move around and even reach under the furniture.

TAKE NOTE: The Boostiq Robovac is suitable for homes with low clearance furniture because of its slim design.

Like most robot cleaners, it functions with a spinning side brush twinned with a rolling brush underneath the body.

When it comes to decibel level, the Boostiq Robovac 11s measures 55 dB. This is comparable to the sound of a dishwashing machine during mid-cycle.

By regular standards, this is definitely considered one of the quietest robot vacuum cleaners!

The unit comes with the following:

  • Charging station
  • Remote control
  • 0.15-gallon dust box
  • 3 power levels (Standard, Mid, and Max)
  • 4 cleaning modes (Automatic Cleaning, Spot Cleaning, Edge Cleaning, and Manual Cleaning)
  • Anti-scratch tempered glass-top cover

Special Features

When cleaning is done, it has an auto charging feature, making it an ideal quiet robot vacuum.

It doesn’t have an app like the more sophisticated robotic vacuum cleaner options, so the way to use it is thru a remote control.

An important factor to also consider is the battery life. Most robot vacuums have a battery life of 60 minutes which is enough to cover a small house with multi-room navigation.

The good news is, Robovac hits the spot at 100 minutes of tested battery life!

| PROS

  • Compact design at 2.8 inches. One of the shortest robotic vacuum cleaner models you will find on the market
  • Affordable
  • Long battery life

| CONS

  • No alert if the dust bin is full. It just picks up less dirt
  • Scheduling options are limited
  • No battery level indicator

4. ECOVACS Deebot Ozmo T8

Ecovac Deebot Ozmo T8

The Deebot Ozmo T8 AIVI is both a robotic vacuum and a mop — how convenient!

The noise level is at 65 dB. Admittedly, you can find other more quiet robotic vacuums. It is not a phantom vacuum where you won’t know it’s there.

While it is not silent, it is also not loud compared to regular vacuum cleaners.

Noise level is low, BUT when it’s running over carpets, it can produce loud sounds which can sometimes get quite alarming.

One thing we particularly love is its exceptional battery life. This robot vacuum cleaner is best used in larger homes.

Special Features

This model is known for its Artificial Intelligence and Visual Interpretation (AIVI) technology. It can avoid obstacles in its cleaning path like power cords and toys.

However, learning how to use it is not that easy, but setting it up to work with the ECOVACS Home App is pretty straightforward, so all is good.

It is also Amazon Alexa and Google Assistant compatible, so you can start and stop cleaning using voice control.

But what sets this apart (and probably what makes it more costly than the average robot vacuum cleaner) is its Visual Butler feature which allows a live video of your home from wherever you are.

The Visual Butler feature of the Ozmo allows you to see a live video stream from your camera. By controlling the arrows in the app, it works like a roving security camera.

So not only does it clean, but it also shows you what’s happening in your home. Some people use this feature to even check on their dogs!

If you have extra dollars to spare, this robotic vacuum cleaner will be a hardworking companion in your home, given its advanced features.

| PROS

  • Has a mopping feature
  • Exceptional battery life (200 minutes)
  • Can do remote home monitoring with its built-in camera
  • Can recognize virtual boundaries

| CONS

  • Very expensive
  • Auto empty station is sold separately
  • No remote control

5. Samsung Powerbot R7040

Samsung Powerbot R7040

The Powerbot R7040 has good maneuverability because of its compact shape. Instead of side brushes, it has a shutter brush that can sweep the dirt against a wall.

When it comes to noise, this vacuum cleaner is generally quiet. However, bear in mind that the surface affects the noise level.

This vacuum automatically detects surface types, and when traversing a carpet, it tends to increase the suction power, adding up a few decibels.

In terms of performance, this vacuum is best suited for homes with furry friends because of its efficiency in picking up pet hair.

NOTE: There are a lot of parts that need to be cleaned regularly. This includes the brush roll, the shutter tool, dirt compartment, filter and the wheels, which often have debris stuck on them.

It comes with:

  • Charging dock
  • Remote control
  • Power cord

Special Features

This Powerbot robot vacuum can be used with the remote, but it also has automation features and a dedicated app that you can control with your phone!

Even if it doesn’t use WiFi, it has a smart pathing feature using its camera to navigate movement around the room.

You can just leave the vacuum in the room, and when the cleaning session in an enclosed room is done and there’s still some battery left, it is smart enough to do another round before going back to the dock!

| PROS

  • Performs well on hard floors
  • Uses Samsung’s Smart Things app to check the status of the robot vacuum, schedule cleaning sessions, and view history
  • Shutter brush is effective in picking up dirt and pet hair (sometimes, the rotating side brush tends to scatter the smaller particles)

| CONS

  • High maintenance
  • Small dust bin capacity (0.08 gal)

Why Get the Quietest Robot Vacuum Cleaners?

Studies show that constant exposure to high noise levels can be detrimental to our health. It’s not so much about damage to our ears due to high volume; it’s more about damage over time.

Exposure to noise from a vacuum cleaner daily for more than an hour can be both annoying and problematic for your hearing.

To give a standardized way to measure the sound level, we use the decibel (dB) as our basis for the quietest robot vacuum.

FOR REFERENCE: Normal conversations and dishwashers operate about 50-60 dB. A car outside your house is around 70 dB.

Even if not all robot vacuum models provide information on the decibel level, we still came up with our top picks based on performance, price, and ease of use.

How Do Robot Vacuums Work?

They’re called robot vacuums because they do the work WITHOUT needing much human intervention.

Like a robot, it has an intelligence of its own!

The Basics

The way robot vacuums work is the presence of one or two rotating brushes that bring the debris inward towards the suction that sucks the dirt into the dust bin of the mechanism.

A combination brush will be an advantage as it can clean an entire space better. Some models also come with a wiper pad to cover even more surface area.

All the dirt collected is stored in a removable compartment which needs to be emptied regularly.

SIDE NOTE: Some higher-end models have an automatic emptying docking station for more convenience!

The Advanced Tech

Robot vacuums are also dependent on multiple sensors. The more common ones are downward-facing sensors that can detect obstacles and avoid them.

BUT, the best robot vacuums can internally map out the room and adjust the cleaning pattern using forward-facing sensors.

Robot vacuum cleaners worth looking into are those with a custom mode. As the name implies, custom mode lets you assign which areas need to be cleaned.

Robotic vacuum cleaners that include cameras and multi-floor mapping will study the area and potential obstacles and use that information to create cleaning patterns that adapt to the environment.

How incredible is that?!

Those WITHOUT cameras and smart mapping rely on sensors to feel their way around, moving in neat rows for cleaning.

SIDE NOTE: Advanced models have five infrared sensors and laser navigation to scout the environment for obstacles.

Good robot vacuum cleaners can be programmed to run on a schedule using on-device controls. The smarter models can be controlled with phone apps and work with Google Assistant.

As an additional function, some vacuums offer mopping attachments. Naturally, using this function would entail more work, such as putting water on the tank and replenishing it when it’s dirty.

WiFi connectivity is fast becoming a standard among robotic vacuum cleaners. With a Wi-Fi-connected robot vacuum, you can schedule cleaning jobs from your phone, including the basic start and stop function.

Limitations of a Robot Vacuum

Owning a robot vacuum may sound like the easiest way to have a perfectly clean home. It is convenient, we’ll tell you that!

But there are also several limitations:

1. They Can’t Clean All Spots

First, robot vacuums tend to leave some spots uncleaned, especially corners or under furniture where they don’t fit.

In this case, it may require extra effort in sweeping or mopping hard-to-reach areas. Some models have better maneuverability, so look for one that suits your suits.

Before rushing to buy your vacuum, measure the distance between the floor and the base of your furniture, like the couch and bed frame.

Needless to say, if the clearance is small, a compact robot vacuum is what you need.

2. They Can Accidentally Suck Up Small Items

Secondly, robot vacuums have sensors to make sure they avoid obstacles and minimize crashing into things, BUT they can still suck up small items like cables, jewelry and trinkets, and small pieces of clothing.

The same goes for large debris of dirt lying on the floor. You still have to supplement your traditional vacuum cleaning with actual sweeping or manually picking up the mess.

3. They Need to Be Moved Manually From Room to Room

Thirdly, depending on the battery life of your robot, vacuum runs might need to be cut short during multi-room navigation.

Therefore, human intervention is still required in moving the vacuum from room to room and across different floor levels.

How to Clean your Robot Vacuum Cleaner: Part by Part

The key to the longevity of your robot vacuum cleaner is in keeping it clean.

For better navigation and suction, you have to unclog the machine of dust and debris.

Robot vacuum cleaners usually come with a cleaning tool. Typically, it has a brush and comb part and a bladed edge.

There are several parts of the robot vacuum cleaner that need to be properly maintained. These include the bin for dust, the air filter, the side and rollers brushes, and the robot cleaner sensors.

Let’s go through each part and the best ways to keep them clean:

Dust Bin

The bin is typically located at the rear side of the robotic vacuum.

Since it stores all the dirt being collected, it is recommended to empty it after every use, even when it is not full. This is to prevent the build-up of hardened dirt.

TAKE NOTE: Dog hair tends to fill up the bin faster.

Air Filter

Robot vacuum cleaners have air filters that are connected to the dustbin. This is where the fine dust particles are trapped.

Once the bin has been emptied, remove the filter over the garbage bin and tap it to take out the debris. You can also use a small brush to remove dust particles stuck on the air venting mesh.

Some models have a removable dust filter that can be washed, although this does not apply to all robot vacs. These filters are usually plastic or foam.

After washing the filter, they must be dried completely before being reinstalled.

There are also a lot of filters that are paper-based and are not recommended to be washed.

Manufacturers recommend replacing these kinds of vacuum filters regularly, around every 2 months, depending on the frequency of use.

IMPORTANT NOTE: Be sure to check the instruction manual before washing.

Brushes

There is usually hair or strings that get stuck on the roller brush.

Here’s how to clean them:

  1. Pull them out from the bottom. You may need to cut through the layers using the bladed edge of your cleaning tool or a pair of scissors.
  2. Once you’ve cut through the layers, pry them off with your hands, then use the cleaning tool’s brush or comb to take additional debris out of the bristles.
  3. For the side brushes, simply wipe off the dirt. For robot cleaners with two side brushes, consider swapping their location from time to time to avoid bending the bristles too far in one direction. If they look worn out or bent, it is best to replace the brushes. Otherwise, your room cleaning will not be as effective.

Sensors

Sensors are located on the sides and bottom of the machine and are critical in navigating their way around to keep the floors clean.

It can be cleaned by simply wiping them with a clean microfiber cloth.

To know the location of the sensors, check the manufacturer’s manual.

Frequently Asked Questions

Why Is My Robot Vacuum So Loud?

When the robot vacuum is set to different cleaning modes, it is normal to make sounds.

But if you notice that it is emitting sounds that are louder than usual, it can be due to any of these factors:

#1 Debris on the Brushes

The first thing to check is if anything is stuck in the brushes.

One of the most common causes of loud noises is large debris being stuck under the robot vacuum.

When the brushes, rubber strap, and extractors cannot turn properly due to blockage, it tends to make thumping sounds.

#2 Too Much Dirt Build Up In the Filter

For most vacuum cleaners, if the filter is too dirty, it creates unnecessary noise. This is because too much dirt build-up obstructs the air vent.

The device has to use more power to do its job.

Take out crumbs, pet hair, cat litter, and hardened dust from the HEPA filters, and you’ll get a more quiet robot vacuum.

#3 Malfunction Due to Loose Parts

An unsecured part is also a common cause of loud noises.

This is particularly true for brush frames and rubber straps.

#4 Worn Out Parts

The brushes or extractors may be working overdrive because they are are clogged with dirt, grime, and most probably hair strands.

For this reason, the device creates a clicking sound. 

Another part that usually gets worn out over time is the wheels.

If the wheels don’t roll smoothly, it can produce noise, especially when traversing through heavy and low pile carpets.

How Do I Make My Roomba Quieter?

The answer to this is simple — proper maintenance of your robotic vacuum.

As mentioned above, in most instances, the reason for a noisy Roomba is loose parts or debris being stuck on the vacuum cleaners.

A quiet robot vacuum should have all parts in place and cleaned regularly.

How Much Noise Does a Robot Vacuum Make?

We should probably talk numbers when answering this question.

In our books, the quietest robot vacuum cleaner should have a noise level below 70 dB.

Not all models provide measurement in decibels, but typical Roomba vacuums have a noise level between 60 decibels (dB) and 70 dB.

TAKE NOTE: Different brands and models of robotic vacuums sound differently.

Generally, the sound it makes depends on the suction power, so the noise varies depending on the type of surface it is cleaning.

Does it mean the more suction power, the more noise?

Not necessarily. It also depends on the setting or functionality.

For example, the spot cleaning function of a particular robotic vacuum cleaner model may sound louder because the machines are cleaning in one small concentrated area compared to moving around a bigger area.

Also, your robot vacuum will have slightly different sound levels depending on different floor types.

Just to manage expectations, regardless of the model, vacuums generally sound quieter when it is vacuuming carpets compared to when it is vacuuming hard floors.

Lastly, let’s not forget that a robot vacuum cleaner will make a loud sound if it isn’t working properly.

PROPER MAINTENANCE IS KEY TO A QUIET ROBOT VACUUM CLEANER!
