Features Of The Tenergy Otis Robot Vacuum Cleaner

Powerful Suction

Powerful suction is always a good thing in a vacuum cleaner. If you have ever used one, you can tell how important it is.

Without a powerful suction, the vacuum will do a poor job of picking dirt, debris, or dust.

This is essentially the main purpose of a vacuum cleaner. So, any one that cannot suction well is not effective.

Though, you can expect the suction power on the Tenergy Otis Robot Vacuum Cleaner to be comparable to that of a full-sized vacuum.

However, it is powerful enough to pick up dirt on all sorts of hard floors and thing carpets. In fact, if you have pets, you will like this robot vacuum some more.

It picks up pet hairs as easily as it does any other form of dirt off the floor. We mentioned earlier that this vacuum can clean on both hard floors and carpets. So, it will help you tackle pet hairs on those floor types too.


Multiple Cleaning Modes

The main reason anyone would want a robot vacuum is that it saves them some vacuuming time.

Not only will it clean your floors without your help, but it is also flexible enough to clean however you want. The Tenergy Otis Robot Vacuum Cleaner has different cleaning modes for different reasons and they are all at your disposal.

First, you can put it on Auto Mode. This leaves the robot to clean your floors at its discretion.

This mode is ideal for routine floor cleaning. That way, your floors will be free of dirt at all times.

Secondly is the Edge Mode. Have you ever had a situation where you had to go manual to clean close to the walls because your vacuum could not reach the dirt there?

That is the problem this mode will help you deal with. In this mode, the robot, with its side brush, will clean up the dirt and leave you with thoroughly cleaned floors.

Thirdly, the Spot Mode. We’re pretty sure you have an idea what this mode does but we will still spell it out.

Sometimes, your floor can already be clean and your robot is just ‘chillin’ on its dock and then your child (or pet) spills dirt. You can just set the Tenergy Otis Robot Vacuum Cleaner to this mode and it cleans up the dirt and goes back to rest.

Last but not least is the Double Cleaning Mode. This is the mode that is best for carpets or high traffic part of the home.


Turbo Mode

The robot doubles its power and goes into a turbo mode. This is where it maximizes its suction power so it can pick up all the embedded dirt.

That’s not all, you can also schedule the Tenergy Otis Robot. You can preset times for it to auto clean the floors.

For instance, you can set it to vacuum when you have gone to sleep so you can wake up to a clean house. You can also set it to clean the floors while you go out. That way, you will come back to a tidy home. That sounds like a good idea, right?


Smart Navigation

How a robot vacuum moves has a lot to do with how well it cleans. These robot vacuums have navigation sensors that help them move about on their own.

They serve like eyes to let it know where it is and how to maneuver. The Tenergy Otis Robot Vacuum moves in a purposeful manner which is why it efficiently covers the floor.

When you put it in the Auto Mode, the robot moves in an “S” pattern which is why it will rarely miss a patch on the floor.


HEPA Filter

If you have been using vacuum cleaners or are allergic, you will appreciate the importance of a HEPA filter in a vacuum.

This type of filter is highly efficient at trapping allergies and microscopic dirt.

If the filter is not good enough, some of the microscopic dirt it takes in might escape. If you inhale these things, it might trigger asthma or allergies.

With the HEPA filter, however, you are quite safe. This filter is so efficient that it traps 99.97% of the microbes and allergens it sucks in down to 0.3 microns.

This means that the particles that can pass through the HEPA filter will have to be smaller than 0.3 microns. Even at that, such a particle has only a 0.03% chance of passing through.

Just to put things in perspective, the diameter of a human hair is about 50 microns. That should give you some level of confidence about the air coming out of this robot.


Large Dust Cup

We told you at the beginning that one of the few things you will have to do for this vacuum is to empty the dust cup.

However, you won’t be doing that often because it is large enough to hold a good amount of dirt before it needs to empty.



User-friendliness Of The Tenergy Otis Robot Vacuum Cleaner

If you have already been liking the Tenergy Otis Robot Vacuum Cleaner, you might like it some more after this.

There are some other features of this robot that might make you consider it user-friendly.

Firstly, this robot is low profile. This makes it convenient for it to sneak under furniture even if it is low profile too.

It does that without getting stuck. With this, you won’t get apprehensive when you need to move furniture with guests around.

Secondly, it has a decent battery life. The vacuum manages power efficiently enough to clean well for long. It lasts for up to 90 minutes before it needs to charge.

That’s not all when it needs to charge, it won’t even need your help. The Tenergy Otis Robot is capable of finding its way to the docking station when its battery is running too low.

It also has large wheels that help it move smoothly across floor types. With this, it can easily go from hard floors onto carpets and back without any issue.

Its wide set dirt inlet makes it clean faster as there is ample space for dirt to pass through. This also makes the suction efficient as it won’t take too much for it to take dirt in.

Now, you have some more detailed features of the Tenergy Otis Robot Vacuum Cleaner. It is up to you to decide if these features make the robot user-friendly to you or not.
