Best Robot Vacuum Under 400

In this article, I compare the five best robot vacuums under $400.

Robotic Vacuums that sell for around $400 are all mid range models, based on the fact that the most expensive models can be bought for around $800.

The comparison chart below displays my 5 best vacuums for under $400 and what features each model has.

In this article, I examined the best robotic hoovers that you could buy for less than 200.

So what sort of features can you expect to get with this price of vacuum that you cannot get on cheaper robot vacuums?

I think that the four features that set these robotic vacuums apart from their cheaper rivals, are;

  • Laser Mapping
  • Auto Charge and Resume
  • WiFi
  • Suction Power and Carpet Boost

Laser Mapping vs Random Bounce

This is the most important difference with cheaper models.

When automatic vacs first came on the market they  moved around the floor using a very simple set of rules. It was the anti collision and anti drop features.

First and foremost they were programmed to move into a straight line until they hit an obstacle. They are programmed to bounce off the object and rotate randomly and start travelling in a straight line until the hit the next obstacle.

This process was repeated, most often until the battery ran out.

Over time, navigation systems have evolved and today’s leading robovacs use a method called VSLAM (Vision Simultaneous Localization and Mapping.)

This method uses infrared beams to create a map of your floor so that they know where they have been and where they need to go next.

Three of the five vacuums in this comparison have the advanced mapping function.

This technology enables the vacuums to move around with much more confidence and not to collide with as many obstacles.

This increased sophistication in navigating also unlocks other functions, which I will explain next.

Auto Charge vs Auto Charge and Resume

Many cheaper robotic vacuum cleaners can auto charge- return to its home base or docking station when its battery is low to recharge.

Once recharged the vacuums would start cleaning again but because they had no idea where they were, some parts of the floor would be cleaned for a second time.

Three of the models in this comparison which have mapping capabilities,once recharging has finished, resume cleaning from the same point as it left. There is no repetition.

This feature is only made possible because of a robovacs mapping capability.

Remote Control vs WiFi

Cheaper robotic vacuum cleaners can’t connect to WiFi and tend to be controlled by a remote control- like the devices that we still use to control our TVs.

Robotic vacuums that cost about $400 do no use traditional remote controls because they can connect to WiFi. The remote control has been killed off and replaced by an app.

The same functions that were on the old fashioned remote controls were now placed inside apps that can be downloaded onto a smartphone.

And although there is not too much difference between the functions on a remote control and the functions within an app, there is a massive difference in how both methods can be used.

Many of the cheaper automatic vac models come with a remote control, which enables a user to control their bot without touching it. But you still need to be in the same room as your vacuum.

Apps provide real remote control because you could be on the other side of the world and still connect with your vacuum.

Suction Power & Carpet Boost

I was surprised to see that the running times of some of the cheaper robot vacuums were higher than the more expensive robots.

Many of the vacuum cleaners in my under $200 comparison have running times of about 100 minutes, whereas the robovacs in this comparison tend to running times of around 60 minutes.

There are two exceptions. The Eufy 11+ has a running time of 100 minutes and the Xiaomi Mi has a running time of 150 minutes.

The reason for this is because the more expensive models have greater suction power and features like “carpet boost” where the device detects when it is travelling on carpet and increases the power.

Common Features

However, there are some common features between a robot vacuum under 200 and a robot vacuum under 400 where there is not much difference between them.

Firstly both sets of devices can clean on all surfaces but it is recommended that they are only used on hardwood, tile or laminate flooring and low pile carpets.

Secondly, there is not much difference the filters on any of the models.

Although the filters are all known by different names, they are designed to filter out the smallest dust particles and allergens possible.

What No Voice?

Something that does surprise me is that only one of the vacuums in my $400 comparison is compatible with the Amazon Echo and Google Home smart home systems.

And that model is the Samsung Powerbot.

Having looked the differences and similarities between cheaper priced automatic vacs and more expensive models, I want to now move onto to look at each of the $400 models in more detail.
