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
The adaptive chassis lift/threshold capability is a standout differentiator, helping it clear taller transitions than many robots. A few reviewers suggest real-world limits can be below marketing claims, but it’s...
Pros: Hard Floor — Fine Dust Pickup, Hard Floor — Large Debris Intake
Cons: None
Threshold handling is a standout: reviews report it can climb around half-inch to three-quarter-inch transitions and generally adapts well to small bumps. Wheels and a floating brush/chassis design help maintain...
Pros: Privacy controls, Stair Cleaning
Cons: Odor control, Hair Pickup — Carpets
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
No adaptive chassis lift, but it still clears many thresholds; deep rugs may suit a lift-equipped model better.
Pros: Low-profile design, Overall durability/longevity
Cons: Clogging &, debris prevention
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
Multiple reviewers emphasize that the S5X does not have the higher-end chassis-lift system found on pricier Curv variants. It can still handle small thresholds (commonly described around 2 cm or...
Pros: Hair‑Wrap / Tangle Resistance, Dirty water sensor
Cons: Accessories &, Tools
This model does not include an adaptive lift chassis, which limits threshold climbing compared with the higher Edge model and some flagships. If your home has tall transitions, this is...
Pros: Odor control, Hair‑Wrap / Tangle Resistance
Cons: Adaptive chassis lift, Headlight &
