Shark Navigator Robot Vacuum RV2120AE (Grey, Self-Empty Base)

How does the SmartPath navigation work compared to other robot vacuums?

The SmartPath system uses spot LiDAR technology to scan and map your home with precision. Unlike basic robots that bump randomly around furniture, this creates detailed floor plans and cleans in organised row-by-row patterns. The mapping ensures up to 1.5 times better coverage than traditional navigation methods, systematically covering every accessible area without missing spots or repeatedly cleaning the same areas.

Does the self-empty base require special bags like other brands?

No, the self-empty base is completely bagless, which saves significant money over time. Other robot vacuum brands require expensive proprietary disposal bags that can cost £20-30 annually. This Shark model uses a reusable container that holds up to 60 days of dirt and debris. You simply empty the container when full and reuse it indefinitely without ongoing bag purchases.

Will this robot vacuum get tangled with pet hair like my previous one?

The anti-hair wrap technology specifically prevents hair tangles that plague other robot vacuums. The self-cleaning brushroll design actively separates hair and prevents it from wrapping around the brush mechanism. This engineering breakthrough means you won't need to manually cut hair from the brushroll every few cleaning cycles, making it ideal for homes with pets or long-haired family members.

What happens if the robot encounters obstacles or gets stuck?

Advanced object detection sensors identify furniture, cables, shoes and other obstacles, allowing the robot to navigate around them automatically. The system adapts to daily changes in your home layout, so you don't need to tidy up before cleaning. If the robot does encounter an unusual situation, it will attempt alternative routes and send notifications through the app rather than simply stopping.

How long does the battery last and what happens if it runs out mid-clean?

The lithium-ion battery provides up to 60 minutes of continuous cleaning time. When battery levels drop during a cleaning session, the robot automatically returns to its charging base. Once recharged, it resumes cleaning exactly where it left off, ensuring your entire home gets cleaned even if it requires multiple battery cycles to complete the job.

Can I control which rooms get cleaned and when?

Yes, the companion app allows you to create custom room boundaries, set no-go zones and schedule cleaning times for specific areas. You can clean your entire home, individual rooms, or spot-clean specific areas using either the app or voice commands. The scheduling feature lets you set daily or weekly cleaning routines that run automatically.

How does the suction power compare to upright vacuums?

While robot vacuums can't match the raw power of full-size uprights, this model delivers up to 50% more suction than competing robot vacuums. The two power levels provide adequate cleaning for daily maintenance on both carpets and hard floors. For deep cleaning or heavily soiled areas, you may still need occasional manual vacuuming, but for regular maintenance this handles most household dirt effectively.

What maintenance does this robot vacuum require?

Maintenance is minimal thanks to the self-cleaning brushroll and bagless self-empty system. You'll need to empty the self-empty base container every 60 days, clean the foam filter occasionally and replace the side brush when worn. The anti-hair wrap technology eliminates the frequent brushroll cleaning required by other models. Overall maintenance requirements are significantly lower than traditional robot vacuums.
