    1 robot vacuum for multiple floors or 1 robotic vacuum cleaner per floor?

    Robot vacuums can’t climb stairs or fly (yet). You have to make the following decision:

    Do you want one robotic vacuum for each floor or one robot vacuum for multiple floors?

    Option 1: One robot vacuum cleaner per floor

    That’s undoubtedly the most convenient alternative.

    For example, if you have a house with 3 floors, you can buy 3 vacuum robots and put them on each floor.

    Advantage: They’ll clean the entire house at the same time. You don't have to carry the robot vacuum from floor to floor. This saves effort and time.

    Disadvantage: It may be convenient, but it’s quite expensive. You’d have to buy a total of 3 vacuum robots (instead of just one).

    Therefore we’d go with option 2 instead.

    Option 2: One robotic vacuum cleaner for multiple floors

    With this option, you have "only" one robotic vacuum that cleans the entire house.

    Your robot vacuum (including the charging station) is therefore only on one floor at a time ("main floor").

    If you want it to clean another floor, you have to carry the robotic vacuum to the (second/third) floor and let the little household helper do its work.

    As soon as it has completed its tasks, you have to carry it back to the main floor. The charging station will be there, too, and the robot vacuum can recharge its battery.

    Advantage: Cost-effective variant.

    Disadvantage: You have to carry the robotic vacuum from floor to floor, which takes more time and effort. You can’t clean several floors at the same time.

    A valuable addition: You could put one charging station on each floor. This way, you wouldn’t have to carry the robotic vacuum cleaner back to the main floor (where the charging station is) after cleaning. You’d only have to move the robot vacuum when you want it to clean another floor.

    Robot vacuums for several (separate) rooms

    It may happen that your robot vacuum can’t enter several rooms due to an insurmountable elevation (e.g. very high door threshold).

    A terrace or balcony are typical examples of that.

    This means that your robotic vacuum cleaner can’t reach the other room.

    Thus, this room is like a second floor.

    So if you want your little household helper to clean both rooms, it should be able to save several maps.

    In our detailed review, "Robot vacuum cleaners for high doorsteps", we address exactly that problem. We’ll show you numerous models that overcome heights well and how your little household helper can climb seemingly insurmountable heights with the help of a robot vacuum doorstep ramp.

    Robotic vacuum cleaner for multiple floors: What should I consider when buying?

    If you live in a house with multiple floors, there are a few things you should keep in mind when buying your robot vacuum.

    The following criteria are essential:

    • Possibility of saving multiple maps
    • Extensive app functions
    • It shouldn’t be only suitable for use on several floors, but also an all-round excellent vacuum robot.
    • Must have crash sensors
    • Good navigation
    • Long battery runtime
    • With wipe function?
    • Individual adjustment of suction power (and water intensity) per floor or room
    • Weight of the robot vacuum
    • Price-performance ratio

    We’ll take a close look at each criterion now.

    Basic Requirement no. 1: Smart Mapping Technology. The robot vacuum must be able to save several maps for multiple floors.

    If you want to use a robot vacuum in a multi-storey house, the device must be able to create and save several maps for several floors (Multi Floor Mapping technology).

    Robot vacuums can create multiple maps of multiple floors and save them in the mobile phone app.

    As soon as you place down the robot vacuum on the second floor, it recognises this and automatically pulls up the correct map.

    This way, your little household helper doesn't have to reorientate himself whenever he has to vacuum the second floor.

    That makes cleaning the second floor much faster, too.

    Another advantage: You always have a detailed map (floor plan) of the second floor, which you can edit as you please (set up virtual walls, merge or separate rooms if necessary, etc.).

    You can find out which features and settings are essential in the next chapter, "Extensive app functions".

    This way you can personalise the daily floor cleaning according to your wishes.

    The key question here is: How many floors does your home have? The robot vacuums can save different amounts of maps. From 2 to 10 maps, anything is possible.

    Basic requirement no. 2: Extensive app functions

    The mobile app determines the intelligence of a “smart” robotic vacuum. And

    It should provide numerous useful functions that make cleaning several floors easier.

    These are the must-have features:

    • Define no-go zones / virtual walls (exclude areas from cleaning - e.g. the children's play corner).
    • Room separation or merging
    • Definition of no-mop zones (e.g. for carpets)
    • Schedule cleaning (e.g. setting the start time of the cleaning)
    • Setting the order of the rooms that the robot vacuum should clean
    • Single room cleaning (send the vacuum to a specific room only)
    • Spot Cleaning (Let the vacuum clean a particular spot)
    • Choosing suction power and water intensity per room (so it can clean very dirty rooms in a stronger cleaning mode/water intensity than less dirty rooms)

    The functions listed above extend the flexibility enormously and make cleaning multiple floors much more manageable.

    Basic Requirement no. 3: Your robotic vacuum for several floors should have an all-round good performance

    The robotic vacuum cleaner shouldn’t only be suitable for use in a house/flat with several floors. It should have top performance in all other relevant areas, too.

    All our top 5 models for multiple floors convinced us in our extensive tests.

    In addition to this, the robot vacuums are also particularly suitable for use in homes with multiple floors.

    It must have crash sensors

    If you have a house/apartment with 2 (or more) floors, there are usually "real abysses".

    Robot vacuum stands in front of a staircase

    Therefore, your robotic vacuum should have built-in crash sensors. They are located on the robot vacuum’s bottom side and are a somewhat standard feature of modern models.

    Crash sensors on the bottom side of a robot vacuum

    It detects precipices in time with these sensors. The robot vacuum will stop immediately and look for another way.

    This way, there’ll be no drama - such as your household helper falling down the stairs.

    Important tip: Always make sure that the crash sensors are clean. We recommend cleaning the sensors with a cloth at regular intervals.

    Navigation

    Your robot vacuum has to clean a huge area if you want to use it on several floors.

    That quickly adds up to cleaning areas of more than 100 m².

    Therefore, you should pay particular attention to navigation.

    The prerequisite for good navigation: the robot vacuum should clean your home seamlessly.

    Navigation speed is also essential. After all, you don't want the robot vacuums to take forever for cleaning the entire home.

    All our "top robot vacuums for multiple floors" have seamless and relatively fast navigation. It took them about ~38 - 50 minutes to clean our 80 m² flat.

    Charging dock and battery: Good battery life is a must

    Your robot vacuum for multiple floors should have a long-lasting and powerful battery.

    Ideally, the robot vacuum should be able to clean several floors in one go without needing a charge in between.

    That’s better because the charging dock may be on a different floor.

    Battery runtimes of 90 minutes and more are sufficient. It can usually clean areas of 150 m² to 250 m² during that time.

    Furthermore, it’s more convenient if your robot vacuum has a "Recharge & Resume" function.

    If the battery runs out during the cleaning, the little household helper returns to the charging station by itself. As soon as the battery is charged, the robotic vacuum continues its cleaning route where it left off.

    It’s a great feature that saves a lot of time.

    A practical tip: If you don’t want to put one charging dock on each floor, you should let the robot vacuum clean the floor without the charging station first. Then you can take it to the "main floor" (where the charging station is) and let it clean there.

    Your advantage: If the battery runs out, the robot vacuum will return to the charging dock by itself and recharge the battery.

    The robotic vacuum will continue cleaning at the same spot where it had to stop. It’ll clean your home seamlessly, even if it has to interrupt its trip, thanks to the "Recharge & Resume" function.

    Mopping Function

    Do you want the robot to vacuum AND mop the floors in your home?

    Robot vacuum with mop do both (vacuuming and mopping) in one go.

    Robot Vacuum with mopping function vacuums and mops the floor at the same time

    The mopping function can’t replace wiping by hand yet.

    Nevertheless, this function ensures that the robot will free your floors from the last traces of dust and dirt. Your home will look even cleaner.

    If you want to learn more about the 2-in-1 hybrid models, then take a look at our detailed "Robot vacuums with wiping function review". Here you’ll find everything you need to know about the topic. We’ll also give you a few tips & tricks to improve your device’s mopping performance.

    You can find a lot of dirt on an entire floor...

    Dirty mop after mopping an entire floor.

    You should rinse the mop thoroughly under running water after each floor.

    Or you could also get a separate mop for each floor. Reusable mops are available on Amazon at a low price.

    Individual setting of suction power (and water intensity) per floor or room

    Different floors can have very different levels of soiling.

    or:

    Different floors can have different floor types (hardwood-floors, low-pile carpet, high-pile carpet).

    There may be highly sensitive laminate flooring on the first floor, whereas the basement has robust tiles.

    Your robotic vacuum cleaner should be able to cope well with all floor types (and all kinds of dirt).

    Modern robot vacuums have a great feature for this:

    You can control the suction power and the water intensity (if there is a wiping function) via the app.

    You can set the suction power and water intensity individually per room in the app

    This means that you can let the robot vacuum clean the basement with the tiled floor at the highest suction level/highest water intensity. For the living area (sensitive laminate flooring), it’ll use the medium power mode/water intensity.

    That increases the flexibility for daily floor cleaning even more.

    Weight of the robotic vacuum cleaner

    The weight of the robotic vacuum cleaner is also quite important.

    If you want that your household helper cleans several floors, you also have to carry it back and forth between the floors.

    The robot vacuums usually weigh approx. 4 - 5 kg

    Thus: the lighter the robot, the better.

    Some models (e.g. iRobot Roomba i7+) also have a practical carrying handle.

    With this, it’s effortless to carry the robot vacuum from one floor to another.

    A somewhat hidden but handy feature!

    Budget and Price-Performance

    You usually have a limited budget.

    Therefore, your new household helper should fit into the budget and offer the best performance/quality possible for the price at the same time.

    Whether it's a price-performance winner (Roborock S5 Max) or a luxury model (iRobot Roomba i7+) - our selection of the "Top robot vacuums for multiple floors" has a model for every budget.

    Conclusion

    Some robot vacuums are very well suited for use in a house with multiple floors.

    Certain functions make it possible.

    The most important one is undoubtedly the possibility to save several maps (for multiple floors).

    These are other features that the robotic vacuum should have:

    • a long-lasting battery and a "recharge & resume" function,
    • a good app with many useful functions,
    • a low weight,
    • fast and seamless navigation,
    • a wipe function (if desired),
