What Is The Best Affordable Robot Vacuum To Buy In 2019?
Dec 30, 2018 5 min read
How many of us thinking about getting a robot vacuum cleaner but not ready to spend thousands of dollars on one? There are 6 budget robot vacuum cleaners you can get for under $300. These are decent machines to buy in 2019.
Gyroscope Mapping Technology
An inertial navigation system (INS) is a navigation aid that uses a computer, motion sensors (accelerometers), rotation sensors (gyroscopes), and occasionally magnetic sensors (magnetometers) to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references.
Mapping based on a gyroscope is not as accurate as the LIDAR system though it is cheaper. A lot of the newest budget robot cleaners use this technology instead of random cleaning pattern. Thanks to this mapping feature, a vacuum covers all cleaning area without missing a spot.
Unfortunately, there is no chance to interact with a map created by the gyroscope.
Only the Eufy 30C and Shark Ion R85 don't have mapping.
The Eufy 30C and Shark Ion R85 are equipped with a bunch of sensors which help them to navigate around yet they do not have mapping.
The robot without mapping randomly runs around until its battery dies. It does not remember where it was cleaning and could go over the same spots a few times when cleaning.
Other robot vacuums that use a gyroscope to map out an interior, move in straight lines thus covering all cleaning area.
How does a robot vacuum cleaner work?
There is a side sweeper (sometimes two sweepers or none) that agitates dust and debris from corners and edges. It transfers dirt to the main brush (or section inlet), the main brush catches dirt from carpet and bare floor and with suction power sends it to the dustbin.
Cliff and anti-collision sensors
The cliff and anti-collision sensors became a standard in the industry.
The infrared beam called anti-collision sensor detects walls and obstacles, so a robot slows down when it gets near them. The touch-sensitive bumper stops the cleaner from hitting things. Infrared sensors called "cliff" help the robot to detect stairs and steep drops.
All the robots are equipped with the sensors.
Auro-Recharge vs. Recharge & Resume
Every robot vacuum which comes with a docking station has infrared sensors that recognize the charging dock and automatically gets to recharge when its battery runs out of energy. If you want your robot to clean one more time, you have to press "start" manually.
Some robot vacuums come with a Recharge & Resume option. When the battery needs to recharge, the robot search for the charging dock and when it's done charging, the vacuum resumes cleaning from the point it left off.
Only the Roborock Xiaowa resumes cleaning after recharging.
In this case, the robot vacuum cleaner finishes cleaning the whole area on its own.
It allows you to set the robot working at a specific time. You can do it using a remote controller or app.
Why do you need an app?
Some robot cleaners come with a remote controller and app. The app allows controlling the robot even when you are not at home, the remote control only when you are near the cleaner.
In the app, you can also see a created map and cleaning history.

What budget robot vacuum cleaner is the best?
The Shark Ion R85 and Eufy RoboVac 15C don't have mapping yet have a magnetic tape in the box that blocks off a particular area. Both are suitable for thin and medium-pile carpets and small homes. The Shark Ion is excellent for pets too.
The Tesvor X500 is good for thin carpets, not suitable for homes mostly covered with carpets.
The Prosvenic 790T is ideal for mixed surface and bare floor. It mops and sweeps, and you can control the dripping water level on the app. The MinSu NV - 01 is the cheapest and would be perfect for someone who is tight on budget. It performs well on both: bare floors and carpets (except thick shaggy rugs). Ideal for homes with any type of surface and for those who have pets.
The Roborock Xiaowa performs the best on carpets. It has the strongest suction and mops bare floor which makes it suitable for any type of flooring. Carpet Boost is the feature budget cleaners don't have. The feature provides deeper cleaning on carpets; gyroscope makes the robot to remember where it was; mopping is excellent for bare floor. For about $300 you get a decent machine with useful features.
