Reviewers who tested thresholds were strongly positive, saying the chassis lift helped the Z70 cross raised thresholds or rugs without getting stuck.
Pros: Noise level, Maneuverability and Handling
Cons: Clogging and debris prevention, Bin and Bag
Adaptive chassis lift was one of the most praised hardware features, helping with thresholds, deep-pile carpet, and unusual obstacles.
Pros: Noise level, Tool-change simplicity
Cons: Ongoing ownership costs (bags, filters
Most reviewers praised AdaptiLift for thresholds, rugs and fewer rescues, though one negative test found threshold behavior unreliable.
Pros: Sanitizing performance, Odor control
Cons: Fresh Liquid Pickup Speed, Ongoing ownership costs (bags
Threshold and clearance handling was praised, with the robot able to cross notable obstacles even with the mop attached.
Pros: Clogging and debris prevention, Versatility
Cons: Storage footprint and upright-stand stability, Stair Cleaning
The liftable brush and mop mechanisms were viewed positively because they move out of the way for mopping, carpet avoidance, and surface changes.
Pros: Ease of use, Overall cleaning convenience
Cons: Scratch resistance, Fresh Liquid Pickup Speed
The adaptive chassis and threshold climbing were major strengths, but one test found real-world threshold performance below the claim.
Pros: Overall cleaning convenience, Runtime
Cons: Solution / Liquid system, Crevice / Groove Pickup (Hard Floors)
Adaptive chassis lift is useful for thresholds and obstacles, though one reviewer found it fell short of the advertised maximum threshold.
Pros: Assembly and Setup, Clogging and debris prevention
Cons: Solution / Liquid system, Suitability for heavy-duty use
The lift chassis helped with thresholds and rugs, but reviewers found limits and one warned against a raised-body carpet setting.
Pros: Tool-change simplicity, Battery and Charging
Cons: Cord management, Support and Reliability
Threshold and chassis handling are rated well, with reviewers noting it can cross half-inch-plus and 3/4-inch transitions.
Pros: Assembly and Setup, Self-cleaning cycle
Cons: Odor control, Fresh Liquid Pickup Speed
Threshold handling was mixed, from easy 1 cm step crossing to criticism that advanced chassis lift was removed or limited.
Pros: Maneuverability and Handling, Versatility
Cons: Under-Furniture Pickup, Low-profile design
Threshold handling is mixed: one review praised 2 cm obstacle navigation, while another found the reduced chassis capability limiting.
Pros: Mopping performance, Controls and UI
Cons: Area Rug Handling, Accessories and Tools
Adaptive chassis lift was a clear weakness because the S5A lacks it and cannot handle the same high thresholds as pricier models.
Pros: Clogging and debris prevention, Floorhead design
Cons: Adaptive chassis lift, Solution / Liquid system
