Adaptive chassis lift

Step/threshold climbing is a standout feature across nearly every source, with repeated claims and demonstrations of clearing tall transitions that stop other robots. Reviewers treat it as a real functional advantage for multi-room homes with raised thresholds.

The self-righting design is a standout feature: multiple reviewers emphasize that if the canister topples, it can right itself and keep going. This reduces interruptions that are common with typical canister vacuums.

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 still viewed as meaningfully better than average.

QuickShift’s rail/lift behavior is frequently praised for making under‑furniture cleaning easier than many uprights. Some testers still find the adjustment less smooth or a bit finicky compared with premium lift‑away designs.

Threshold and transition handling is generally strong, with reports of confidently crossing room thresholds and climbing onto rugs. This supports mixed-floor homes with multiple surface changes.

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 contact on uneven surfaces.

The chassis and wheel design can handle modest thresholds and some taller rugs better than many bots, improving room-to-room coverage. Extremely tall steps remain out of scope and require manual moves.

Threshold handling is described as capable for typical door transitions, with some reviewers noting it can climb modest height changes without drama.

The Easy Leap/threshold system is useful for modest transitions (and getting onto thicker rugs), but it’s not at flagship ‘leg’ levels and performance can vary with real-world threshold shapes.

Cleaner-head height or gate adjustments help it transition between surfaces and handle variable pile heights, though very thick carpet can still feel grabby.

The lift mechanism is a standout, helping the robot climb saddles, transitions, and some rugs while keeping the mop off carpet. Performance can vary with very tall thresholds or detection timing.

The lift/threshold system helps with moderate transitions and carpet behavior, but results are mixed on very tall or flat thresholds and a few reviewers call the clearance claims over-optimistic.

Adaptive chassis lift/threshold handling is a helpful capability for small steps and thresholds (noted around ~0.79 inches), but it’s not positioned as the best-in-class step climber versus specialized competitors.

The lift/threshold behavior is a noted advantage for handling bumps and some transitions, though it does not solve every real-world snag scenario and may require supervision on first runs.

No adaptive chassis lift, but it still clears many thresholds; deep rugs may suit a lift-equipped model better.

Threshold handling is described as adequate for small transitions (often cited around 20mm/2cm). Reviews also note it won’t handle larger steps/thresholds well, which can limit access to certain rooms in some homes.

Threshold/step climbing is limited, with at least one review warning it cannot clear taller thresholds (around 2.5 cm) without assistance or ramping.

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 roughly 3/4 inch), but may struggle on taller transitions or inconsistent thresholds.

Multiple reviews note it lacks an advanced adaptive chassis lift system, limiting its ability to handle taller thresholds. It may clear small bumps, but it is not designed for aggressive step or threshold climbing.

Reviews explicitly note it does not have an adaptive chassis lift feature. It can still handle standard thresholds, but it won’t match lift-equipped robots for challenging height changes.

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 a notable constraint.
