Robot vacuum cleaner: a guide to choosing the best one.

A robot vacuum cleaner (also called a robot vacuum or robot vacuum cleaner ) can be the best "anti-stress" purchase for keeping your home clean every day — but only if you choose the right model for your space.

Below you have a straightforward guide, designed for homes in Portugal (tiles, laminate flooring, carpets, pet fur) and for purchases that are "regret-proof".


1) First you decide: vacuum only, or vacuum + mop?

A) Robot vacuum cleaner for vacuuming only

Ideal for: daily maintenance of dust, crumbs, pet hair and light to medium dirt.
✅ Simpler, usually cheaper.

B) Robot vacuum cleaner with mop (2-in-1)

Ideal for: hard floors (tile, laminate) where you want to "mop" regularly.
⚠️ Important: a mop is great for maintenance, but it doesn't replace a deep clean when there's grease/old footprints.


2) Navigation and mapping: LiDAR vs. camera (vSLAM) — why this changes everything

The robot's "brain" determines whether it cleans in an organized way or just walks around the house.

  • LiDAR (laser): measures distances and creates maps with great precision, aiding in efficient navigation.

  • vSLAM (camera): uses vision/camera to map and orient itself, capturing the environment visually.

✅ Practical tip (very useful for shopping):

  • A house with many rooms and routines → good mapping makes all the difference (areas, rooms, "no-go zones").

  • If you have cables, socks, toys → look for obstacle detection/avoidance (many models combine sensors + AI).


3) Autonomy, recharging and cleaning area (error #1)

For large areas, autonomy is crucial. DECO recommends aiming for an autonomy of at least 100 minutes for cleaning large areas.
Almost all of them return to the base to recharge, but the recharge time varies considerably (some models take from ~1h30 to >5h; average ~3h30).

✅ How to choose without overthinking:

  • Small apartment → "average" autonomy is sufficient

  • Large house → prioritizes autonomy + good mapping (and ideally "automatic resume" after recharging)


4) Self-emptying tank and station: is it worth it?

Robots have small dustbins (DECO typically refers to 0.2 L to 1 L ).
That's why stations/docks with larger tanks that automatically empty the robot were developed.

✅ It's definitely worth it if:

  • Do you have pets? (Their fur grows back quickly)

  • Do you have a big house?

  • Do you really want "zero maintenance" on a daily basis?

⚠️ It may not be worth it if:

  • You have a small house and don't mind emptying it 2-3 times a week.

  • You have little space for the station.


5) Carpets, fur, and corners: what to look for

Rugs and carpets

  • He is looking for " carpet boost " (increased power on the carpet) and an effective main brush.

  • Check if the robot can climb your type of carpet (pile height and fringe).

Pets

  • Prioritize anti-tangle (or easy-to-clean) brushes and good sealing/filtering.

  • If you have a lot of hair → a self-draining station is a real upgrade.

Corners and baseboards

DECO tests, among other things, its effectiveness in corners and crevices , as well as on hard floors and carpets.
✅ In practice: shape, side brush, and navigation have a big influence here.


6) App and control: the functions that really matter

Search for at least:

  • Map by divisions + names of the divisions

  • no-go zones / virtual barriers

  • scheduling (automatic cleaning)

  • power adjustment and (if applicable) mop water levels

  • Cleaning history and maintenance alerts

If you want full automation, voice integrations (assistants) can be "extras," but they're not essential.


7) Maintenance and consumables (to make the robot last for years)

Simple routine:

  • Clean the main and side brushes (bristles).

  • Empty the tank (or change the station bag)

  • clean sensors and wheels

  • Wash/replace filters as needed.

  • Replace consumables (brushes/filters/mops) when necessary.

✅ Golden rule: a well-maintained robot retains suction, navigation, and avoids odors.


FAQ

What is the best robot vacuum cleaner for homes with carpets?
It seeks good mapping, "carpet boost," and an effective brush. On higher carpets, it confirms its climbing ability and power.

Is a robot vacuum cleaner with a mop worth it?
Yes, for maintenance on hard floors. For heavy dirt/grease, you still need to clean manually from time to time.

Is a self-emptying station worth it?
It's especially useful in large homes with pets because the robot's tank is small and fills up quickly.

How long does it take for a robot to recharge?
It varies considerably between models (there are cases ranging from ~1h30 to >5h; average ~3h30).

Is LiDAR better than a camera?
These are different technologies: LiDAR measures distances with a laser and usually maps with high precision; vSLAM uses a camera/vision to map.
