Stairs are very common in our house, it’s very easy for us to go across. however stair is still a problem for robot vacuums. such as: The sweeper fall down from stairs easily, robot couldn’t go across stairs, robot work on stairs hardly. with many years developments, we already overcome some problems, but there are problems that still need time to solve it.

Question For Robot Vacuum Stairs

Question 1: Robot Vacuum Cleaner Can Avoid Fall Down Stairs ?

Falling down from stairs are very often in the past. because the robot navigation & stair safety technology are not very mature. for many customers, it could be one of the concern when buying a robot vacuum.

In 2021, Now it won’t be a problem again. the anti-falling technology has a huge improvement. it’s become the very basic requirement for robot vacuum manufacturer. on market, there is no any risk of falling when robot working.

Like klinsmann robot vacuums, all the robots use stair safety technology, equipped with 3 pairs anti-drop sensors in the bottom, it can detect the step and make the decision to avoid stairs.

Question 2: Robot Vacuum Climb Stairs?

There are many research for a design to make robot vacuum that can climb stairs. in the past, there is a group did a work base on irobot roomba, they made flying robovac. however it failed, because it’s not pratical.

There is no stair cleaning robot at present, perhaps it may appeared in the future

Robot vacuum cleaner can run at hardwood & tile floors, carpets, some even can go across small gap. that’s because robot vacuum fit with Retractable Wheels, it can climb with small slope ( Less than 15 degrees), but the slope for stair is 90 degrees & the high normally higher than robot, all that means it’s impossible for robot to climb Stairs

Question 3: Is cleaning robot that can work on stairs ?

The width for regular stair is about 10cm, but the width for robot normally can reach 35cm, like Klinsmann K196, the smallest robot, the width can reach 32cm, which is much bigger than stairs, that means there is no more space for robot working.

All in all, we hope to have a stair vacuum robot. our robot vacuum already get improved for stairs. but because of design & technology limitation. today there is no real practical robot vacuum for stairs. but we believe in it. it will be designed in the future.

How to clean your stairs ?

Stairs is very simple for human, but it’s very complicated for robot vacuums. At present, the best machine for stair cleaning should be cordless stick handheld vacuum.

For example, Klinsmann T21 & T20 are good choice. Sweeping, Vacuuming & Mopping 3 in 1. Lightweight design & More Powerful sunction. Flexible Motorized Soft Roller Brush and Led Light, which are more suitable for stairs

Also the price compared with robot vacuum is more cheap, only different is that it’s handheld, couldn’t be 100% automatically.
