How to buy robot vacuum cleaner? Follow a few tips to choose the BEST from the BUNCH. 

Navigation: It’s the most important factor to consider. Powerful navigation implies the robo-vac will continue working without bumping into anything or getting stuck to any place. SLAM, an old mechanism and VSLAM, a new-age mechanism are two widely popular technologies used in making of robot vacuum. 

Suction Power: Robo-vacs with high suction power perform deep and detailed cleaning at the tight corners and on high pile carpets. 

Battery Life: Long battery life is a big plus for any robot cleaner. The robot vacuums with long-lasting battery life can work non-stop for a long time. 

Brush: This factor matters a lot when it comes to carpet cleaning. You should choose a model that comes with soft bristles as it will do deep cleaning without damaging your carpet.  

Height & Wheels: Small is a bliss. Cleaners with short heights can easily smuggle themselves under low-height furniture. Right selection of wheels is also important so that robo-vacs can make a smooth switch from floors to carpets. 

HEPA Filter: The feature ensures that dirt and dust sucked by the robot vacuum don’t return to air.   

You will find all these points elaborated in details in our robot vacuum cleaner buying guide.

How effective are robot vacuums? It depends on makes and models. However, the working mechanism remains same for all of them. Our experts explain it in details.

Robot vacuums use their built-in motherboards to map your floor plans, store those in memory and navigate throughout your home accordingly. Sensors prevent the robot from bumping into objects and guide it to choose the best cleaning route. 

Some models come with an HEPA filter to eliminate allergens from the inside air of your home. Once the robot is done with its cleaning work or it requires recharge, it will flash or beat and get back to its docking station.

Most robotic cleaners use integrated technology that provides them with 4-5 different cleaning modes. They seem to be cleaning in a random fashion. They choose a crisscross pattern, then spiral and finally crawl your walls. By using sensors, they navigate around the barriers and objects and often clean up the same area repeatedly in the process. 

Some of the best robot vacuum cleaners come with camera and lasers for home mapping to plan the best route for cleaning. They usually work in a linear pattern just like a human being. Once cleaning in one room is done, it moves to the next one. 


Operating a robot vacuum is super easy. Before plugging in the machine, you need to do a little bit of work such as, clearing laundry, lightweight mats or charging cables as most bots easily get stuck to these objects. You will experience some hitches during the first few sessions. After you use it regularly for a week or so, you will be able to identify the pain points and eventually find using the robot cleaner not a very big deal.  


Robot vacuums require a little bit of maintenance. In most homes, a bot will remain in mint condition for years. Just 15-minute of maintenance work every month is enough. It the bot needs to deal with heavy workloads, a little more maintenance is needed. 

Visit Amazon to buy a Robot vacuum cleaner that comes with several advanced features for a very low price….

Some Essential Tips on Robotic Vacuum Maintenance 

  • Replace the filter in your robot vacuum every few seasons. You can use third-party filters to save some money. Don’t worry; third-party filters will neither harm your machine nor negatively affect its performance. However, if get caught, you may get your warranty cancelled.
  • Remove any hair that might get wrapped around the brush as it rolls to collect dirt in your room. Most bots have a tool that can cut the fuzzes and brush them away. 
  • Keep the bearings on the brush roll cleaned. Cleaning should also be performed regularly (every few weeks) on side brushes and caster. You might have to use a screwdriver for this job but with many bots, you can easily remove the parts without any tool. 
  • A can of compressed air comes handy if you need to wipe away the dust accumulated on gears and other hard-to-access nooks in the machine.
  • Replace side brushes and filters a few times every year. The brush roll needs once-a-year replacement. You should also replace the battery whenever needed. Most bots need a new battery every second year though requirement for a replacement is directly related to frequency of use. 


Our robot vacuum buying guide will help you decide what to look for when buying a robot vacuum to clean high pile carpets. Whether your choice is the best or worst comes down to an array of certain key factors. Though the concept of BEST or WORST is often a subjective matter, we have tried to give it an objective aspect by categorizing the BEST BUYS under different categories as listed above. 

The height of the appliance, battery life and cleaning mechanism matter most. Keep in mind that the PERFORMANCE LEVEL for cleaning hardwood floor is way different from that on thick carpets. Let us now get to the brass talks:


Of all the must-consider features for the best robot vacuum purchase; some are related to cleaning whereas the rests are requisite for quick action and good performance. The robot vacuum with BEST NAVIGATION means the robot will neither get stuck to any place nor slip off the stairs. Only a good navigation system ensures efficient and quick cleaning. 

SLAM and VSLAM are two widely known navigation technologies. SLAM is an old-fashioned navigation mechanism whereas VSLAM is the latest type that makes the machine’s cleaning performance much better and faster.

Suction Power

Suction power matters a lot when it comes to buying a robot vacuum for high pile carpets. You will experience problems when working with a robot vacuum having poor suction power. Dust and debris tend to settle down to the bottom of hard pile carpet. Buy best rated robot vacuum cleaner in United States with high suction power (minimum of 1000Pa) and two power modes as it can perform powerful cleaning on different floors; otherwise, cleaning work will remain incomplete and ineffective. 

A cleaner with double modes triggers the power boost option on the carpet surface and switches to low power while working on hard floors. 

Choosing a cleaning appliance with high suction power or a robot vacuum with easy-to-adjust suction feature will be a wise decision. Don’t be tempted to settle for a cheap option. If your purpose is not served, it will be a complete drain out of your hard-to-earn money. 

Battery and Charging

Robot vacuums are no-cord appliances. Therefore, it’s important to check the battery life as well as how much time it takes to fully charge. Battery life that sustains for one hour is considered good as that will enable the robot vacuum to cover most of your space on a single recharge. Some appliances come with 2 hours’ of battery life but these are expensive. 

If we talk about charge time, a robot vacuum takes 3-4 hours for full recharge. If you shop for a robot vacuum for cleaning floors at an affordable budget on Amazon, it will take not more than 5 hours for full recharge. Some appliances feature self-charging. It means when the appliance senses that it will run out of charge soon, it uses the little charge remaining to get back to its base for charging itself. However, make sure that the device comes with both Self-Recharge and Resume features; otherwise, it will not be able to resume function after recharging itself. 

The self-recharge feature is an advanced feature and very important. With so many gadgets at your home, you will hate a new addition to the list that you need to remember for timely recharge. Even if you forget, the self-charging robot vacuum can recharge itself without anyone’s intervention. 

Height & Wheels

Height matters a lot and so do wheels. If you buy a robot vacuum with wrong-sized wheels, it will experience difficulties while moving from floor to carpet. The reason is the carpet and the floor are not on the same level and therefore, bumps create obstacle in the way. The right size of wheels is important for the appliance to switch between the surfaces with ease.

Continue to follow our quick tips for buying robot vacuum cleaner……..

Height is another important criterion to consider as good height enables it move around easily beneath furniture. Robots, which are relatively short and lightweight, have some advantages over their taller and bulkier counterparts. This is because, they can easily get under furniture and work better while moving over thresholds and making transitions from bare floors to carpets. 


Shape is, however, not super important. The D-shaped bots work much better at corners. Round bots with side brushes can also achieve the same result unless your corners have heavy dust piled up. 


Brush plays a key role in cleaning. It’s not a super important factor for hardwood but of utmost importance if carpet cleaning is in question. Robot vacuums with hard bristles damage the fabric of the carpet. Tangling is another issue if a hard bristled robot vacuum performs cleaning work on your carpet.

Use a cleaner having soft bristle brushes. The tango-free brushes are the best type as these neither get stuck nor negatively affect the carpet. A robot vacuum with tango-free brushes is designed around the right mechanism that does not involve pulling out the fibers from the carpet and won’t leave it with an uneven and unattractive surface. A vacuum cleaner with S9 type bristle works best for high pile carpets. 

HEPA Filter 

Nearly all the best-selling robot vacuum cleaners across US feature air filtration. It’s an important criterion that you should not let go off your radar. Some buyers, without being aware of its importance, skip the feature just to save a few bucks. If you think that way, let’s warn you that it’s not a good idea to go with. A robot vacuum with HEPA filtration ensures that all the microscopic elements, already sucked by the system, don’t return to the air. In case of carpets, especially hard pile carpets, HEPA Filter is of primordial importance because a lot of dust and debris tend to build up in the carpets. 


So far, we have discussed only the MACRO factors. We will now switch our focus to the MICRO factors. Let’s get into the details.

Navigation Speed

Navigation speed matters a lot. You will surely want your robot vacuum to do the cleaning work as quickly as possible. Bum-and-Run bots are a good option as they continue working until they run out of their battery power. Mapping bots work much faster than bump bots. Check prices and reviews of robot vacuums and mops on Amazon. There are some remarkable differences in different mapping bots though most of them come within the same 20 per cent range. 

Cleaning Mode

From our personal experience, we can conclude the most robot vacuum users never use any additional feature. However, a spot-cleaning mode is the commonest find on the list of add-ons whereas manual steering option is less common. These features work great when it comes to cleansing small, contained messes. 


It is a MAJOR factor if you have a big hairy feline or canine creature and so, you are looking for a highly efficient vacuum cleaner for removing pet hairs. Most users complain that the dustbin fills up very quickly but only the first few times when they work with it. After one week’s of regular cleaning, you will notice gradual improvement in its ability to collect pet hairs. The bin size varies from model to model but that is insignificant. 

Some bots feature self-emptying bins. These are extra-large bins fitted on top of the charring dock and assembled to absorb the dust and debris right out of the robot. It’s an excellent feature that enables you to schedule a cleaning setup and makes the appliance function like an automatic one. 


There are quieter robots and there are louder robots. The first type is surely better, especially when you are at your home and the robot is doing its cleaning work. Buying the quietest robot vacuum cleaner to clean hard floors has some clear advantages over the louder cleaners. 

From 10 feet away, a machine with 55dBC won’t create much of problem. Many models run at around 60dBC which is not more than background noise in your office. Stronger bots come in around 65dBC when they are working on bare floors, which is much quieter than any common vacuum cleaner. But the sound will be jarring on your nerves after 20 minutes or so.

Carpet Surface

An ideal robot vacuum is equally efficient on all surfaces. However, such an ideal item lives only in our imagination and never exists in reality. From our experiments, we can safely say that a robot vacuum can work best on a particular floor texture and not on all. The robots, which are good on hard floor, are less likely to be as effective on high pile carpets. However, there are a few most affordable robot vacuum cleaners on Amazon, which are more or less equally efficient on all surfaces. 

Boundary Markers

It’s obsolete if you buy a bot featuring interactive maps. But the feature is a useful one if you buy a simpler bot. The feature prevents the machine from knocking out water bowls or your pet’s food or getting into the zone where it is more likely to get stuck. An unobtrusive bot really helps. Many mapping bots will allow you to create clear yet invisible boundaries through your smartphone app. Some bots depend on magnetic strips spread across your floor. Usually cheap bots don’t feature boundary markers. However, doors, if closed, work as a good barrier for the bots. 

Wi-Fi & Smart Home Integration

These controls are handy to start and stop the bot when you’re not at home. Apps make it easier to set up a schedule for cleaning, keep a track of when replacing a part is necessary or adjust certain cleaning settings. A physical remote control is a handy tool if your bot does not feature Wi-Fi. The appliances having Wi-Fi feature are sophisticated robot vacuum cleaners with high price tags.

The problem with the bots featuring wireless connectivity is they can go wrong like other Wi-Fi-supported appliances. On top of that, troubleshooting in such cases will give you big headache. 


It’s interesting to note that the design of a robot vacuum is not a parameter of how good it’s at cleaning but a function of the cleaner’s performance. Don’t go with a thick robot vacuum. If your robot vacuum can easily get under the furniture and other hard-to-reach areas where manual cleaning is done only once in a blue moon, it definitely features a smart and functional design. The robot vacuums with wheels deliver a better cleaning result for high pile carpets. They are also ideal for long area movement. Some cleaners are also designed to be durable. 

Reliability & Durability

Purchase a solid vacuum cleaner at an affordable budget on Amazon. These are common concerns among the buyers, regardless of the type of appliance they are looking for. Some models withstand daily use for years even if they are on low maintenance whereas others meet an immature death within only a couple of years and repairing does not contribute much to their lifespan extension. 

As you might need repairing down the road, go with a model that features easy-to-access replacement parts. Brushes and filters are easily available but it often gets difficult to find wheels and spare batteries. 

Smart Features

New-age features are smarter and better to make your life much easier. These enable you to schedule a cleaning program according to your convenience. You can create the program weekly, daily or hourly, whatever suits your purpose. Another exciting feature is Wi-Fi connectivity through apps that let you operate your cleaner via your smartphone. In the age of Alexa and Google Assistant, which work much faster, the so-called smart features are no longer smarter enough. 

Visit Amazon to buy a robot vacuum cleaner that comes with several smart features at a very low price.
