Let’s dive in and make sure you get the most value out of your pool robot—whether you already own one or you’re just doing your homework before you buy.

Section 1: General Basics 

1. What is a robotic pool cleaner and how does it work?

A robotic pool cleaner is a self-contained, plug-in device that automatically cleans your pool using electric motors, rotating brushes, and onboard filters. Unlike suction or pressure-side cleaners that rely on your pool's pump system, robotic models are fully independent. You simply plug it into an outlet, drop it into the pool, and let it do the work.

2. Can I leave my robotic pool cleaner in the pool all the time?

It’s tempting to just leave it in, but manufacturers generally don’t recommend it. While most robotic cleaners are waterproof and safe to use for extended cleaning sessions, long-term submersion can wear down seals, electronics, and components more quickly—especially in chlorinated or saltwater environments.

Best practice: Remove the cleaner after each use, clean the filters, and store it in a shaded, dry area when not in operation.

3. Can I swim while the pool robot is working?

Technically, yes—but it's not ideal. Robotic cleaners are low-voltage and safe by design, but for both safety and performance reasons, it's better to avoid swimming while the robot is in operation.

Also, human activity can disrupt the cleaner's path or cause it to miss areas during its cleaning cycle.

4. Can I run my pool robot in the rain?

Most robotic pool cleaners and their control units are water-resistant, but the power supply unit is not waterproof. If it starts raining, you should remove or safely cover the power supply to prevent damage or electrical hazard.

5. Can I use a pool robot after shocking the pool?

Wait at least 24–48 hours after shocking your pool before using a robotic cleaner. The high chlorine or chemical levels could degrade internal components, seals, and brushes.

6. Do I need to turn off the pool filter while the robot is working?

You don’t have to, but it’s usually beneficial to run the robot independently. Since robotic pool cleaners have their own filtration system, keeping your pool’s pump and filter off can help conserve energy and allow the robot to trap more debris efficiently.

7. How often should I run my robotic pool cleaner?

This depends on pool usage, size, and surroundings. For most residential pools, 2–3 times per week is enough during swim season. If your pool is under trees, used daily, or in an area with heavy debris (like pollen or dust), daily cleaning might be necessary.

8. Can robotic pool cleaners be used in saltwater pools?

Yes—most modern robotic pool cleaners are built to handle saltwater environments. Just make sure the manufacturer explicitly states saltwater compatibility.

Salt can be corrosive over time, so it's especially important to rinse the cleaner with fresh water after each use and store it properly to extend its lifespan.

Section 2: Cost & Value

9. How much does a robotic pool cleaner cost?

Robotic pool cleaners typically range in price from $300 to over $1,500. Entry-level models with basic functionality may cost between $300–500, while high-end units with advanced features like Wi-Fi, smart navigation, and wall-climbing abilities often exceed $500.

10. Are robotic pool cleaners worth the investment?

Yes—for most pool owners, a robotic cleaner pays for itself over time. While the upfront cost is higher than suction or pressure cleaners, the benefits are substantial:

  • Lower long-term energy costs
  • Reduced wear on your pool’s pump and filter
  • Better cleaning performance
  • Time savings—no more manual vacuuming
  • Extended life for your pool surface due to regular cleaning
11. Why are robotic pool cleaners more expensive than other types?

Robotic cleaners are standalone machines with their own motors, sensors, microprocessors, and filtration systems. They don’t rely on your pool’s plumbing or pump, which makes them more efficient—and more complex.

12. Are there affordable models that still perform well?

Absolutely. If your pool is small or doesn’t accumulate heavy debris, there are great models under $600 that can clean floors and some walls effectively. If you're not familiar with the market, take a look at Mammotion's newest pool cleaning robot, the SPINO E1, which is sure to meet your needs.

Section 3: Features & Performance

13. Do robotic pool cleaners pick up dirt and fine debris?

Yes—robotic pool cleaners are designed to handle everything from large leaves to fine dirt, sand, and silt. Most models come with dual-layer filtration systems that separate larger debris from tiny particles, preventing cloudiness and improving water clarity.

14. Does a robotic pool cleaner pick up leaves and twigs?

Most robotic pool cleaners can handle small to medium leaves and twigs. However, if your pool is located under trees and gets large volumes of debris, choose a model with:

  • A large-capacity filter basket
  • Strong suction power
  • Wide intake ports
15. Can robotic pool cleaners clean algae?

Yes—light algae, especially surface-level and early-stage growth, can be removed by robotic cleaners thanks to their rotating brushes. However, they won’t eliminate an active algae bloom.

16. Do robot pool cleaners climb walls and clean the waterline?

It depends on the model. Mid-range and premium models often have wall-climbing capabilities and can scrub all the way up to the tile line. Entry-level robots may only clean the pool floor.

17. Do I still need to brush my pool if I have a robot?

Not entirely, but occasional manual brushing is still recommended. Robotic cleaners can’t always reach narrow steps, complex ledges, or corners. Brushing helps loosen algae or grime so the robot can pick it up more effectively.

18. Do robotic cleaners ever get stuck or miss areas?

Older or budget models may occasionally get stuck on main drains, ladders, or irregular steps. Modern robots use advanced navigation, gyroscopes, and cordless design to reduce missed spots and ensure full pool coverage.

19. How long does a robotic pool cleaner take to clean a pool?

Most robotic pool cleaners complete a cleaning cycle in 1.5 to 3 hours, depending on pool size, shape, and debris level. Some models let you adjust cleaning cycles or choose “quick clean” modes for faster jobs.

20. Do robotic pool cleaners use a lot of electricity?

Not at all. They’re among the most energy-efficient pool cleaning options. Most models use 50–100 watts per hour, similar to a household light bulb—far less than running a traditional pool pump.

21. Do robotic cleaners plug into a regular outlet?

Yes. Robotic pool cleaners come with a low-voltage transformer power supply that plugs into a standard 110V outlet. Some newer models are cordless and battery-powered, offering more flexibility (though they often have shorter runtimes).

Section 4: Usage, Maintenance & Storage

22. How often should I robot vacuum my pool?

For most residential pools, running the robotic cleaner 2–3 times per week is ideal during swim season. However, if your pool gets heavy use, sits under trees, or collects a lot of debris or pollen, you may want to run it daily or every other day.
