Robot Vacuums Shape and Charging and auto-return, Battery Power

Not many people know that the cleaning robot’s size and shape effects it’s sweeping abilities. Read on to learn how:

Round robots Round robots

This is the most common design made popular by the industry-leading iRobot. While its Roomba may not have been the first to enter the market, it’s the most commercially viable automatic vacuum which is why other companies entering the market copied its design scheme.

Round robots easily get around areas and with bumper sensors can avoid hard impacts to furniture. They are however limited in their ability to traverse corners and walls and without side whiskers, it may have been impossible for these round shape units to get into walls and corners.

Squared robots Squared robots

While squared devices are not common, they are very effective cleaners. An example is the Neato Botvac Robotics which easily gets into corners and close to walls. Their sides whiskers ensure it reaches within millimeters of baseboards, and reach into corners like no other machine can. The only drawback with this design is that there’s a high possibility of it getting stuck in between chair legs.

Charging and auto-return

The ability of a cleaning robot returning to its base on its own is now a standard feature for all models. The machine locates its base using a radio frequency signal and then guides itself to the base once its battery starts to lose power.

The percentage of battery power that triggers this function varies between devices but is usually between 5-15%. Its better if the base is located in some unobstructed place and should not be influenced by other radio signals which may interfere with its locating the base.

Even the range of it locating its base varies with models some have only a 5-foot radius outside the base while others can locate their base at much wider areas. The higher-end models have features which help them locate the base from wherever they are.

The bots typically slow down to the base and onto the charger. Most robotic vacuums are programmed to complete their assigned task once they get charged and will continue with the charge-clean-charge process till they complete the task.

Battery power 

The cleaning robot’s battery power is very important as it defines how much power your robotic vacuum consumes. They are generally power-hungry and average between 1 hour to 1 ½ hour per charge.

This may seem a long time for a traditional carpet sweeper but that’s how long an automated sweeper works on a charge as it’s much slower than traditional devices. Moreover many robot vacs have limited suction power and thus does not use its battery too quickly.

The best robot vacuums have 2 hours of battery life and models which offer longer battery life usually sacrifice its cleaning power to achieve this. However many buyers are not willing to sacrifice here as stronger suction is needed to remove dust from carpets, floors and rugs. (Full Review)
