Is the Roborock Saros Z70 worth its current price?

The reviewer initially purchased the Roborock Saros Z70 for $2,000, which he considered far too expensive for its capabilities. He noted that a recent sale price of around $1,200 is much more reasonable. Despite the price reduction, he stresses that its first-generation robotic arm is limited and the navigation system often gets stuck.

How reliable is the robotic arm on the Roborock Saros Z70?

The robotic arm on the Z70 is a first-generation feature and is quite limited in its functionality. The reviewer observed it occasionally jamming on shoelaces during its cleaning cycles, though he noted its durable build prevented any damage. He hasn't seen significant software updates to improve its performance over six months of use.

Does the Roborock Saros Z70 clean floors effectively?

Yes, the robot vacuum cleans very well, delivering strong performance in picking up dirt and debris. The reviewer demonstrated this by cutting open the dust bag after six months, revealing it was completely full and compacted with dog hair and other household dirt. Its specialized brush design also effectively prevents long hair from wrapping around.

What is the navigation performance like on the Roborock Saros Z70?

The Roborock Saros Z70 uses a 'StarSight' navigation system rather than traditional LiDAR, and the reviewer found it gets stuck quite often. It particularly struggles with U-shaped or rod-shaped furniture, requiring the user to set up no-go zones. While it records a history of successful cleanings, its pathfinding is not perfect, leading to occasional bumps.

What maintenance is required for the Roborock Saros Z70?

The reviewer performed a deep dive into maintenance, including cleaning the clean and dirty water tanks, solution tank, filter, dust bag, sensors, side brush, main brush, and mop pads. He highlights that the filter needs frequent cleaning, and the dust bag, if not replaced, can fill completely within six months. The robotic arm itself requires very little maintenance, mainly just blowing off any dust.

Source verdict

The reviewer concludes that the Roborock Z70 is very well-built and cleans effectively, but finds its original $2000 price too high, suggesting $1200 is more reasonable. While the Generation 1 robotic arm is a novel feature, it has limitations, often jams, and lacks significant software improvements. The robot also struggles with navigation around specific furniture types.

About this source

This video provides a deep dive into the maintenance procedures for the Roborock Saros Z70 robot vacuum after six months of real-world use. The reviewer demonstrates cleaning various components, discusses the performance of its Generation 1 robotic arm, and shares his final verdict on its value and effectiveness.

Review notes

The Roborock Saros Z70 is a well-built robot vacuum that delivers strong cleaning performance, but its first-generation robotic arm and StarSight navigation are significant bottlenecks. After six months, the reviewer observed the robotic arm frequently jamming on shoelaces, though the robot's robust build prevented damage. Its StarSight navigation system, which lacks traditional LiDAR, often causes the unit to get stuck around U-shaped furniture. However, the vacuum's core cleaning function performs very well, evidenced by a completely full dust bag after six months of use. If you prioritize robust cleaning and durable construction and are willing to set up no-go zones, this robot might suit you at a reduced price. However, if you expect flawless object sorting or advanced navigation, you should consider alternatives with more mature robotic arm technology and LiDAR.

What the reviewer liked

Robot is extremely well-built and durable
Delivers strong cleaning performance
Robotic arm is durable and didn't fail even when jammed
Dust bag has good capacity, collecting a lot of debris over time
Ionizing beads/tablets prevent odor in the dirty water tank
Specialized brush design prevents long hair wrap
Maintenance tasks are straightforward to perform

What the reviewer criticised

Original price of $2,000 was too expensive for its capabilities
Robotic arm is generation one, very limited, and sometimes jams on shoelaces
Lacks LiDAR navigation, using 'StarSight' which causes it to get stuck often around U-shaped/rod-shaped furniture
Thin design can lead to getting into trouble and bumping into objects
Navigation is not perfect, despite mapping capabilities
Dust bin size is relatively small before auto-emptying

Structured claims

The robotic arm requires very little maintenance, mainly just blowing it off.

reviewer_claimstrong

The Roborock Saros Z70 robot is very well-built, with its robotic arm withstanding jams without failure.

reviewer_claimstrong

The Roborock Saros Z70 is a reasonable purchase at its current price of around $1200, but was too expensive at its original $2000 price point.

reviewer_claimmoderate

The Generation 1 robotic arm on the Roborock Saros Z70 has limited functionality, picks up very little, sometimes jams, and has not seen significant software improvements.

reviewer_claimstrong

The Roborock Saros Z70 provides very good cleaning performance, as evidenced by its full dust bag after 6 months of use and extensive cleaning history.

reviewer_claimstrong

The robot often gets stuck on U-shaped and rod-shaped furniture due to its navigation system, which lacks LiDAR in the front.

reviewer_claimstrong

The dust bag system is effective, completely full after 6 months, simple to use, and does not leak, offering a benefit over bagless systems by not requiring extra filter cleaning.

reviewer_claimstrong

The Roborock Saros Z70 features a specialized brush roller with cutters that effectively prevents long hair from wrapping around it.

reviewer_claimmoderate

The base station for the Roborock Saros Z70 has a removable cleaning tray, making maintenance easier and more convenient compared to systems that require cleaning on hands and knees.
