Frequently asked questions (FAQ) about robotic vacuum cleaners:

What are the Pros and Cons of RoboVac?

RoboVacs are not good in terms of cleaning carpets. Small particles like hairs, dust, etc., can not be sucked up properly by an average RoboVac, as they need high suction power to be removed from the carpet. In this case, traditional vacuums are best. But not all RoboVacs fail in this job. Some high-quality ones will cost a little extra, but they will clear up your floor with perfection. If you are running out of time to maintain your daily tasks, a RoboVac is there to make your life easier.

What is the lifespan of a RoboVac?

This measurement has been generated by analyzing the consumer report over the years. A good quality RoboVac can support you for almost five years. But it does not matter how long the lifetime is if you cannot maintain your electronics properly. So, you cannot avoid proper maintenance.

How frequently it should be used?

In terms of operating a cleaning machine, it fully depends upon your need. Like, you use a washing machine when you have dirty clothes to be washed. Just like that, you operate your vacuum when your floor or carpet gets dirty. But it is advised to use a RoboVac daily. Otherwise, if the amount of dirt gets higher, it may cause an issue while sucking up.

Is RoboVac noisy?

No. One of the advantages of a RoboVac is, that it does not produce loud noise like the traditional ones. As the robotic vacuum lacks suction power over the traditional cleaners, they run quietly.

Usage of electricity & costing

If the tension of the electric bill does not let you sleep at night, a robotic vacuum cleaner is a blessing for you. It consumes less electricity per unit of time. That’s why it can be described as an energy-saving appliance. A chart of the energy consumption rate is provided below –

Power of vacuum Cost per hour(approximately)
800W 0.38 ¥
1000W 0.47 ¥
1200W 0.57 ¥
1600W 0.76 ¥
1800W 0.85 ¥
2000W 0.95 ¥
2200W 1.04 ¥
2400W 1.14 ¥

How to operate a RoboVac device?

The RoboVac is comparatively easy to operate via Wi-Fi. But it is still ok if you do not have a Wi-Fi connection. You cannot control different functions without Wi-Fi. By operating with Wi-Fi, you can schedule your RoboVac’s working period remotely. The machine will do its job automatically. Most people use it with Wi-Fi.

Can traditional and robotic vacuums replace each other?

Till now, no. RoboVacs do not have all the functionalities like regular ones. Again, regular vacuums do not provide the facilities like robots. RoboVacs will operate as long as the battery is charged. On the other hand, regular vacuums will run as long as you provide an electric connection. A quick comparison can explain better why not-

Specifications Robotic Vacuum Cleaner Traditional Vacuum Cleaner
Suction Power Low High
Electricity Consumption It depends on the power used per unit. But comparatively less than the traditional ones. Comparatively higher than the robotic vacuums.
Batteries Rechargeable Both rechargeable and non-rechargeable
Noise Low High
Carriable Yes No
Operated by Wi-Fi, Mobile App, Alexa Human
