The robot vacuum with the grabby arm, Roborock’s Saros Z70, has dropped to $1,399.99 at Amazon. That’s $1,199.01 off its regular list price of $2,599, a hefty 46 percent discount and Amazon’s lowest price tracked by deal watchers at sites like Camelcamelcamel.
At this price point, Roborock’s most headline-grabbing model transitions from a niche showpiece to a serious player for high-end cleaning setups — even if the robotic arm concept remains more of a conversation starter than a must-have feature.
The robotic arm everyone is talking about on the Z70
The Saros Z70’s integral arm is used to remove small impediments so that the bot can complete a task without human assistance. In demos, it suctions socks, toys, and light detritus into a pile to the side before going over an area as part of the cleaning pass.
Early independent testers have found it to be clever but not reliable, especially with items that are irregular in shape and soft fabrics. The good news: it’s completely optional. You can turn off the arm in settings or limit it to individual rooms and categories of objects, and use your Z70 as a traditional obstacle avoidance cleaner when home cleaning is more important.
The Core Cleaning Still Carries The Pitch
Behind all the flourish, the Z70 is a typical Roborock flagship: powerful suction and firm brush agitation for carpets, along with a pressure-sensitive mopping system that scrubs hard floors with a consistent coverage pattern.
Its 3D mapping and LiDAR navigation create accurate floor plans and direct the bot methodically instead of bumping around.
The multi-function dock performs those hated tasks like automatic dustbin clearing, washing and drying the mop, and refilling the water tank, so you’re left with what can become a once-in-a-while emptying of the bin and checking the pads. That’s the real time-saver for large houses and pet owners who might want reliable, repeatable results — all without daily tinkering.
Price context and rivals in the premium robot market
$1,399.99 is the same bar I’m willing to accept for other premium all-in-ones that have been announced lately, including the Ecovacs Deebot X2 Omni and Dreame’s top-of-the-line L-series models, and just north of deals we frequently see on something like the iRobot Roomba Combo j7+, which comes with its own separate self-emptying base.
Roborock’s in-house S8 MaxV Ultra is a common point of comparison for suction and AI navigation; the Z70 compounds that by adding an arm experiment on top of the same formula.
Consumer Reports and other testing labs tend to focus more on aspects like pickup performance, navigation reliability, and maintenance costs ahead of flashy features. On those fronts, Roborock’s higher-end units are always highly rated when it comes to mapping and dock automation. The cut-price potential of the Z70 makes for a more fundamental recommendation if you never make use of the arm.
Industry watchers like IDC say that premium floor care is one of the faster-growing corners of the smart home, as docks get smarter and object recognition improves. The Z70 ticks those boxes while pushing the boundaries of what a domestic robot can achieve.
Who should consider the Z70 and when it makes sense
Homes with mixed surfaces, pets, and multi-room floor plans will benefit most from the Z70’s mapping and dock maintenance. The arm is there to help on good days, if you’re a constant victim of street debris, but expect to do some tidying before starting runs if you don’t turn it off entirely for consistency.
Prior to purchase, make sure you have room for the dock, skim the most recent firmware notes in the Roborock app for news about stability updates, and check your retailer’s return window. Like any high-end robot, long-term happiness can also depend on software updates and how easily you can find replacement brushes, filters, and mop pads.
The bottom line on value, features, and this discount
This is the best price yet on Roborock’s most impressive robot. The arm is fun to have, but it’s more of an extra than a daily driver; the value comes from the vacuuming, scrubbing, mapping, and hands-off dock. At 46% off, the Saros Z70 starts to make sense for buyers who seek top-tier cleaning without a moonshot premium.
